ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. AGENCY: We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 767–300 and 767–300F series airplanes. The NPRM proposed to require modification and installation of components in the main equipment center. For certain other airplanes, the NPRM proposed to require modification, replacement, and installation of flight deck air relief system (FDARS) components. The NPRM was prompted by reports of malfunctions in the flight deck display units, which resulted in blanking, blurring, or loss of color on the display. This action revises the NPRM by revising the applicability; adding certain modifications; and clarifying certain requirements. We are proposing this supplemental NPRM (SNPRM) to prevent malfunctions of the flight deck display units, which could affect the ability of the flightcrew to read the displays for airplane attitude, altitude, or airspeed, and consequently reduce the ability of the flightcrew to maintain control of the airplane. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes. DATES: We must receive comments on this SNPRM by July 11, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov.

Discussion We issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 767–300 and 767–300F series airplanes. The NPRM published in the Federal Register on September 25, 2013 (78 FR 58970) (‘‘the NPRM’’). The NPRM proposed to require modification and installation of components in the main equipment center. For certain other airplanes, the NPRM proposed to require modification, replacement, and installation of FDARS components. Actions Since the NPRM Was Issued Since we issued the NPRM, we have reviewed Boeing Alert Service Bulletin 767–21A0245, Revision 2, dated September 27, 2013 (for Model 767– 300F series airplanes). We referred to Boeing Alert Service Bulletin 767–21– 0245, Revision 1, dated September 30, 2010, as an appropriate source of service information for accomplishing certain actions specified in the NPRM. Boeing Alert Service Bulletin 767–21A0245, Revision 2, dated September 27, 2013, adds instructions for modifications to reduce noise in the flight compartment when the 3-way valve is operating by removing flex ducts that connect the center and aft parts of the air distribution diffuser in the main deck cargo compartment, installing caps and an orifice assembly in the area forward of the main equipment center and under the flight deck floor, and installing an FDARS. Boeing Alert Service Bulletin 767–21A0245, Revision 2, dated September 27, 2013, also identifies concurrent actions (relay installation and related wiring changes). Those concurrent actions are described in Boeing Service Bulletin 767–21–0235, dated October 8, 2009; and Boeing Service Bulletin 767–21–0235, Revision 1, dated July 29, 2011. We have also reviewed Boeing Alert Service Bulletin 767–21A0247, Revision 1, dated April 9, 2013 (for Model 767– 300F series airplanes). We referred to Boeing Alert Service Bulletin 767– 21A0247, dated October 10, 2011, as an appropriate source of service information for accomplishing certain actions specified in the NPRM. Boeing Alert Service Bulletin 767–21A0247, Revision 1, dated April 9, 2013, adds airplanes to the effectivity of the service bulletin and includes procedures for E:\FR\FM\27MYP1.SGM 27MYP1 rmajette on DSK2TPTVN1PROD with PROPOSALS Federal Register / Vol. 81, No. 103 / Friday, May 27, 2016 / Proposed Rules changes to the 3-way valve control logic, modifications to reduce noise in the flight compartment and main cargo air distribution system (MCADS), and installation of an FDARS. The service bulletin also adds concurrent actions (relay installation and related wiring changes) for a certain group of airplanes. Those concurrent actions are described in Boeing Service Bulletin 767–21– 0235, dated October 8, 2009; and Boeing Service Bulletin 767–21–0235, Revision 1, dated July 29, 2011. We also have reviewed Boeing Service Bulletin 767–31–0073, dated October 12, 1995, which is referred to as concurrent service information in Boeing Service Bulletin 767–21–0244, Revision 1, dated March 8, 2010 (which is referred to as an appropriate source of service information for changing the 3way valve control logic and installing a cooling system for the flight deck display equipment). Boeing Service Bulletin 767–31–0073, dated October 12, 1995, describes procedures for installation of an in-flight engine indication and crew alerting system (EICAS) for the maintenance data selection system. We have revised paragraphs (c)(2), (h)(1), and (j) of this proposed AD to refer to Boeing Alert Service Bulletin 767–21A0245, Revision 2, dated September 27, 2013. We have also revised paragraphs (c)(3) and (h)(2) of this proposed AD to refer to Boeing Alert Service Bulletin 767–21A0247, Revision 1, dated April 9, 2013. In addition, we removed paragraph (k) of the proposed AD (in the NPRM), ‘‘Credit for Previous Actions,’’ from this proposed AD because operators that have accomplished the actions in Boeing Service Bulletin 767–21–0245, dated April 16, 2010; or Boeing Alert Service Bulletin 767–21A0245, Revision 1, dated September 30, 2010; must do additional work when accomplishing the procedures specified in Boeing Alert Service Bulletin 767–21A0245, Revision 2, dated September 27, 2013. We have redesignated paragraph (j) of the proposed AD (in the NPRM), ‘‘Concurrent Requirements,’’ as paragraph (k)(1) of this proposed AD. In addition, we have added a new paragraph (k)(2) to this proposed AD to address the concurrent actions (relay installation and related wiring changes) identified in Boeing Alert Service Bulletin 767–21A0247, Revision 1, dated April 9, 2013. Also since the issuance of the NPRM, we have reviewed Boeing Alert Service Bulletin 767–21A0254, dated June 7, 2013 (which was not referenced in the NPRM). Boeing Alert Service Bulletin 767–21A0254, dated June 7, 2013, VerDate Sep<11>2014 15:22 May 26, 2016 Jkt 238001 describes procedures for installing the FDARS and activating the 3-way valve control logic change for certain Model 767–300F series airplanes. We have redesignated paragraph (g) of the proposed AD (in the NPRM) as paragraph (g)(1) of this proposed AD, and added a new paragraph (g)(2) to this proposed AD to require the actions in Boeing Alert Service Bulletin 767– 21A0254, dated June 7, 2013. Comments We gave the public the opportunity to comment on the NPRM. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Clarify the Applicability of the Proposed AD (in the NPRM) Boeing requested we state that the proposed AD (in the NPRM) does not apply to Model 767–300 (passenger) series airplanes. Boeing explained that the 3-way valve control logic for Model 767–300 (passenger) series airplanes is significantly different from the 3-way valve control logic for Model 767–300F and Model 767–300BCF (Boeing Converted Freighter) series airplanes. Boeing indicated that, on Model 767– 300 (passenger) series airplanes, pack air (which is a moisture source on the freighter airplanes) to the flight deck instruments and equipment is rarely used. Boeing added that Model 767–300 (passenger) series airplanes only utilize airplane pack air during override and fuel jettison modes, and there have not been reports of moisture-related display blanking on these airplanes. We find that clarification is necessary. This proposed AD applies to Model 767–300 and 767–300F series airplanes, as identified in certain service information. ‘‘Model 767–300 series airplanes’’ could include both passenger and BCF series airplanes. According to the U.S. type certificate data sheet for Model 767 airplanes, a Model 767– 300BCF series airplane is a Model 767– 300 (passenger) series airplane that has been modified in accordance with specific service information to operate in a freighter configuration. The service information identified in the applicability of this proposed AD addresses Model 767–300BCF series airplanes and Model 767–300F series airplanes—not passenger airplanes. Therefore, this proposed AD does not apply to Model 767–300 (passenger) series airplanes. We have added this clarification to paragraphs (c), (i), and (k)(3) of this proposed AD. PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 33613 Request To Revise the Proposed AD (in the NPRM) To Remove Certain Service Information References Boeing asked that all references to Boeing Service Bulletin 767–21–0240 be removed from the NPRM, including the applicability statement. Boeing stated that the intent of this service information is to incorporate display improvements on Model 767–300BCF series airplanes. Boeing has confirmed that the actions to prevent display unit blanking included in Boeing Service Bulletin 767–21–0240 have already been incorporated on Model 767–300BCF series airplanes during the conversion, prior to re-delivery. Boeing also asked that all references to Boeing Service Bulletin 767–21–0244 be removed from the NPRM, including the applicability statement. Boeing stated that the intent of this service information is also to incorporate display improvements on Model 767– 300BCF series airplanes. Boeing has confirmed that the actions to prevent display unit blanking included in Boeing Service Bulletin 767–21–0244 have already been incorporated on Model 767–300BCF series airplanes in advance of this proposed AD. Since Boeing Service Bulletin 767– 21–0240 has been incorporated on the affected airplanes during the conversion and prior to re-delivery, we agree with the commenter’s request to remove references to that service bulletin from this proposed AD. Paragraph (c) of this proposed AD has been revised to omit Boeing Service Bulletin 767–21–0240, Revision 1, dated November 12, 2009, from paragraph (c)(1), and subsequent subparagraphs in paragraph (c) have been redesignated accordingly. However, we do not agree with the commenter’s request to remove references to Boeing Service Bulletin 767–21–0244 from this proposed AD. The commenter has not submitted documentation to the FAA for verification that the affected operators of Model 767–300BCF series airplanes have accomplished the actions to prevent display unit blanking that are included in Boeing Service Bulletin 767–21–0244, Revision 1, dated March 8, 2010. Therefore, Boeing Service Bulletin 767–21–0244, Revision 1, dated March 8, 2010, is still referenced in this proposed AD. Paragraph (h)(3) of the proposed AD (in the NPRM) has been omitted from this proposed AD because it referred to Boeing Service Bulletin 767–21–0240, Revision 1, dated November 12, 2009 (which affects airplanes on which the service information has been done during the conversion and prior to re- E:\FR\FM\27MYP1.SGM 27MYP1 33614 Federal Register / Vol. 81, No. 103 / Friday, May 27, 2016 / Proposed Rules rmajette on DSK2TPTVN1PROD with PROPOSALS delivery), and the airplanes identified in this service information have been removed from the applicability of this proposed AD, as explained previously. However, the requirements for the remaining Model 767–300BCF series airplanes (i.e., those subject to accomplishment of Boeing Service Bulletin 767–21–0244) have been moved from paragraph (h)(3) of the proposed AD (in the NPRM) to new paragraph (i) of this proposed AD. Paragraph (k) of this proposed AD, which correlates to paragraph (j) of the proposed AD (in the NPRM), has been revised to remove the concurrent requirements for Model 767–300BCF series airplanes identified in Boeing Service Bulletin 767–21–0240, Revision 1, dated November 12, 2009. The concurrent requirements for Model 767– 300BCF series airplanes identified in Boeing Service Bulletin 767–21–0244, Revision 1, dated March 8, 2010, are retained in paragraph (k)(3) of this proposed AD. Request To Clarify the Requirements of the Proposed AD (in the NPRM) Boeing requested that the requirements of the proposed AD for Model 767–300BCF versus Model 767– 300F series airplanes be clarified. Boeing stated that the intended function of the 3-way valve control logic change is to provide moisture control to mitigate display blanking; however, the intended function of the FDARS is to mitigate the noise that resulted from the 3-way valve control logic change, not to control moisture and mitigate display blanking. Boeing stated that the proposed 3-way valve control logic change and addition of the FDARS should be required for Model 767–300F series airplanes, and only the 3-way valve control logic change should be required for Model 767–300BCF series airplanes. We agree to clarify the requirements of this proposed AD. In light of the commenter’s remarks, we revised paragraphs (g)(1) and (g)(2) of this proposed AD to state that, for Model 767–300F series airplanes, the required actions include the installation of an FDARS and activation of or change to the 3-way valve control logic. We also revised the heading for paragraph (g) of this proposed AD accordingly. In addition, we revised paragraphs (h)(1) and (h)(2) of this proposed AD to state that, for Model 767–300F series airplanes identified in Boeing Alert Service Bulletin 767–21A0245, Revision 2, dated September 27, 2013, and Boeing Alert Service Bulletin 767– 21A0247, Revision 1, dated April 9, 2013, respectively, the required actions VerDate Sep<11>2014 15:22 May 26, 2016 Jkt 238001 include a change of the 3-way valve control logic and MCADS, and installation of an FDARS. We also revised the heading for paragraph (h) of this proposed AD accordingly. As previously discussed, a new paragraph (i) is included in this proposed AD. This paragraph specifies that, for Model 767–300BCF series airplanes, only the installation of the 3way valve control logic and flight deck display equipment cooling system is required. The subsequent paragraphs have been redesignated accordingly. Request To Revise the Number of Affected Airplanes Boeing requested that the number of affected airplanes be changed from 43 to 58. Boeing stated that based on its current records of operators, there are 58 Model 767–300F series airplanes of U.S. registry. Based on the number of affected Model 767–300 and 767–300F series airplanes currently on the U.S. Register, we changed the number of affected airplanes to 52 in the ‘‘Costs of Compliance’’ section of this SNPRM. We also made additional changes to the ‘‘Costs of Compliance’’ section to account for any added requirement of this proposed AD. Effect of Winglets on Accomplishment of the Proposed Actions Aviation Partners Boeing stated that the installation of winglets per Supplemental Type Certificate (STC) ST01920SE (http://rgl.faa.gov/ Regulatory_and_Guidance_Library/ rgstc.nsf/0/ 59027f43b9a7486e86257b1d006591ee/ $FILE/ST01920SE.pdf) does not affect the accomplishment of the manufacturer’s service instructions. We agree with the commenter that STC ST01920SE (http://rgl.faa.gov/ Regulatory_and_Guidance_Library/ rgstc.nsf/0/ 59027f43b9a7486e86257b1d006591ee/ $FILE/ST01920SE.pdf) does not affect the accomplishment of the manufacturer’s service instructions. Therefore, the installation of STC ST01920SE does not affect the ability to accomplish the actions required by this AD. We have not changed this SNPRM in this regard. Additional Change Made to This Proposed AD We incorrectly referred to the original issue date of Boeing Service Bulletin 767–21–0235 as July 29, 2011, throughout the NPRM. We have specified the correct date of the original issue of Boeing Service Bulletin 767– 21–0235 as October 8, 2009, in PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 paragraphs (j) and (k) of this proposed AD. Related Service Information Under 1 CFR Part 51 We reviewed the following service information. • Boeing Alert Service Bulletin 767– 21A0245, Revision 2, dated September 27, 2013.

This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA’s Determination We are proposing this SNPRM because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Certain changes described above expand the scope of the NPRM. As a result, we have determined that it is necessary to reopen the E:\FR\FM\27MYP1.SGM 27MYP1 Federal Register / Vol. 81, No. 103 / Friday, May 27, 2016 / Proposed Rules comment period to provide additional opportunity for the public to comment on this SNPRM. Requirements of This Proposed AD This proposed AD would require, depending on airplane model and configuration, the following actions: • Replacing the existing duct with a new duct. • Installing an FDARS. • Changing or activating the 3-way valve control logic. • Installing a new altitude switch and pitot tube. • Changing the 3-way valve control logic and MCADS. • Installing a flight deck display equipment cooling system. • Doing a relay installation and related wiring changes. 33615 • Installing an in-flight EICAS for the maintenance data selection system. Refer to the service information described previously for details on the procedures and compliance times. Costs of Compliance We estimate that this proposed AD affects 52 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost 3-way valve control logic and MCADS change, and installation of an FDARS (Boeing Alert Service Bulletin 767–21A0247, Revision 1, dated April 9, 2013; Groups 2 and 3 airplanes). 3-way valve control logic and MCADS change, and installation of an FDARS (Boeing Alert Service Bulletin 767–21A0245, Revision 2, dated September 27, 2013). Replacement of the existing duct, installation of an FDARS, 3-way valve control logic change, and installation of a new altitude switch and pitot tube (Boeing Alert Service Bulletin 767–21A0253, dated October 12, 2012). 3-way valve control logic change and installation of a flight deck display equipment cooling system (Boeing Service Bulletin 767–21–0244, Revision 1, dated March 8, 2010). Relay installation and related wiring changes (Boeing Service Bulletin 767–21–0235, dated October 8, 2009; or Boeing Service Bulletin 767–21–0235, Revision 1, dated July 29, 2011). Installing an in-flight EICAS for the maintenance data selection system (Boeing Service Bulletin 767–31– 0073, dated October 12, 1995). Replacement of the existing duct, installation of an FDARS and activation of 3-way valve control logic (Boeing Alert Service Bulletin 767–21A0254, dated June 7, 2013). According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. rmajette on DSK2TPTVN1PROD with PROPOSALS Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs’’ describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in VerDate Sep<11>2014 15:22 May 26, 2016 Jkt 238001 Cost on U.S. operators 46 work-hours × $85 per hour = $3,910. $21,865 $25,775 .......... $1,185,650 (46 airplanes). 64 work-hours × $85 per hour = $5,440. 18,315 23,755 ............ 47,510 (2 airplanes). 76 work-hours × $85 per hour = $6,460. 55,663 62,123 ............ 248,492 (4 airplanes). 33 work-hours × $85 per hour = $2,805. 0 2,805 .............. 8,415 (3 airplanes).

FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: I. Table of Abbreviations CFR Code of Federal Regulations DHS Department of Homeland Security FR Federal Register NPRM Notice of proposed rulemaking § Section U.S.C. United States Code II. Background, Purpose, and Legal Basis On March 10, 2016, the Fort Armstrong Folk Festival notified the Coast Guard that it will be conducting a 30-minute fireworks display between 9 p.m. and 10 p.m. on August 6, 2016. The fireworks will be launched from a barge in the vicinity of Allegheny River mile 43.5 to mile 44.5. Hazards from fireworks displays include accidental discharge of fireworks, dangerous projectiles, and falling hot embers or other debris. The purpose of this rulemaking is to ensure the safety of vessels and the navigable waters before, during, and after the scheduled event by establishing a 90-minute safety zone beginning 30 minutes before the display until 30 minutes after the display is over during the hours of 8 p.m. to 11 p.m. on the same date. The Coast Guard proposes this rulemaking under authority in 33 U.S.C. 1231. III. Discussion of Proposed Rule The Captain of the Port Pittsburgh (COTP) proposes to establish a safety zone lasting 90 minutes between the hours of 8 p.m. and 11 p.m. on August 6, 2016. The safety zone would cover all navigable waters of the Allegheny River from mile 43.5. to mile 44.5. The PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 33617 duration of the zone is intended to ensure the safety of vessels and these navigable waters before, during, and after the fireworks display scheduled to take place for 30 minutes between 9 p.m. and 10 p.m. on the same date. No vessel or person would be permitted to enter the safety zone without obtaining permission from the COTP or a designated representative. The regulatory text we are proposing appears at the end of this document. IV. Regulatory Analyses We developed this proposed rule after considering numerous statutes and Executive orders related to rulemaking. Below we summarize our analyses based on a number of these statutes and Executive orders and we discuss First Amendment rights of protestors. A. Regulatory Planning and Review Executive Orders 12866 and 13563 direct agencies to assess the costs and benefits of available regulatory alternatives and, if regulation is necessary, to select regulatory approaches that maximize net benefits. Executive Order 13563 emphasizes the importance of quantifying both costs and benefits, of reducing costs, of harmonizing rules, and of promoting flexibility. This NPRM has not been designated a ‘‘significant regulatory action,’’ under Executive Order 12866. Accordingly, the NPRM has not been reviewed by the Office of Management and Budget. This regulatory action determination is based on the size, location, and duration, of the safety zone and the low traffic nature of this area. The safety zone will close a small section of the Allegheny River for less than two hours. Moreover, the Coast Guard would issue a Broadcast Notice to Mariners via VHF–FM marine channel 16 about the zone, and the rule would allow other waterway users to seek permission to enter the zone. Requests to transit the safety zone area would be considered on a case-by-case basis. B. Impact on Small Entities The Regulatory Flexibility Act of 1980, 5 U.S.C. 601–612, as amended, requires Federal agencies to consider the potential impact of regulations on small entities during rulemaking. The term ‘‘small entities’’ comprises small businesses, not-for-profit organizations that are independently owned and operated and are not dominant in their fields, and governmental jurisdictions with populations of less than 50,000. The Coast Guard certifies under 5 U.S.C. 605(b) that this proposed rule would not E:\FR\FM\27MYP1.SGM 27MYP1

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

-----------------------------------------------------------------------

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) for certain The Boeing Company Model 767-300 and 767-300F series 
airplanes. The NPRM proposed to require modification and installation 
of components in the main equipment center. For certain other 
airplanes, the NPRM proposed to require modification, replacement, and 
installation of flight deck air relief system (FDARS) components. The 
NPRM was prompted by reports of malfunctions in the flight deck display 
units, which resulted in blanking, blurring, or loss of color on the 
display. This action revises the NPRM by revising the applicability; 
adding certain modifications; and clarifying certain requirements. We 
are proposing this supplemental NPRM (SNPRM) to prevent malfunctions of 
the flight deck display units, which could affect the ability of the 
flightcrew to read the displays for airplane attitude, altitude, or 
airspeed, and consequently reduce the ability of the flightcrew to 
maintain control of the airplane. Since these actions impose an 
additional burden over that proposed in the NPRM, we are reopening the 
comment period to allow the public the chance to comment on these 
proposed changes.

DATES: We must receive comments on this SNPRM by July 11, 2016.

Discussion

    We issued an NPRM to amend 14 CFR part 39 by adding an AD that 
would apply to certain The Boeing Company Model 767-300 and 767-300F 
series airplanes. The NPRM published in the Federal Register on 
September 25, 2013 (78 FR 58970) (``the NPRM''). The NPRM proposed to 
require modification and installation of components in the main 
equipment center. For certain other airplanes, the NPRM proposed to 
require modification, replacement, and installation of FDARS 
components.

Actions Since the NPRM Was Issued

    Since we issued the NPRM, we have reviewed Boeing Alert Service 
Bulletin 767-21A0245, Revision 2, dated September 27, 2013 (for Model 
767-300F series airplanes). We referred to Boeing Alert Service 
Bulletin 767-21-0245, Revision 1, dated September 30, 2010, as an 
appropriate source of service information for accomplishing certain 
actions specified in the NPRM. Boeing Alert Service Bulletin 767-
21A0245, Revision 2, dated September 27, 2013, adds instructions for 
modifications to reduce noise in the flight compartment when the 3-way 
valve is operating by removing flex ducts that connect the center and 
aft parts of the air distribution diffuser in the main deck cargo 
compartment, installing caps and an orifice assembly in the area 
forward of the main equipment center and under the flight deck floor, 
and installing an FDARS. Boeing Alert Service Bulletin 767-21A0245, 
Revision 2, dated September 27, 2013, also identifies concurrent 
actions (relay installation and related wiring changes). Those 
concurrent actions are described in Boeing Service Bulletin 767-21-
0235, dated October 8, 2009; and Boeing Service Bulletin 767-21-0235, 
Revision 1, dated July 29, 2011.
    We have also reviewed Boeing Alert Service Bulletin 767-21A0247, 
Revision 1, dated April 9, 2013 (for Model 767-300F series airplanes). 
We referred to Boeing Alert Service Bulletin 767-21A0247, dated October 
10, 2011, as an appropriate source of service information for 
accomplishing certain actions specified in the NPRM. Boeing Alert 
Service Bulletin 767-21A0247, Revision 1, dated April 9, 2013, adds 
airplanes to the effectivity of the service bulletin and includes 
procedures for

[[Page 33613]]

changes to the 3-way valve control logic, modifications to reduce noise 
in the flight compartment and main cargo air distribution system 
(MCADS), and installation of an FDARS. The service bulletin also adds 
concurrent actions (relay installation and related wiring changes) for 
a certain group of airplanes. Those concurrent actions are described in 
Boeing Service Bulletin 767-21-0235, dated October 8, 2009; and Boeing 
Service Bulletin 767-21-0235, Revision 1, dated July 29, 2011.
    We also have reviewed Boeing Service Bulletin 767-31-0073, dated 
October 12, 1995, which is referred to as concurrent service 
information in Boeing Service Bulletin 767-21-0244, Revision 1, dated 
March 8, 2010 (which is referred to as an appropriate source of service 
information for changing the 3-way valve control logic and installing a 
cooling system for the flight deck display equipment). Boeing Service 
Bulletin 767-31-0073, dated October 12, 1995, describes procedures for 
installation of an in-flight engine indication and crew alerting system 
(EICAS) for the maintenance data selection system.
    We have revised paragraphs (c)(2), (h)(1), and (j) of this proposed 
AD to refer to Boeing Alert Service Bulletin 767-21A0245, Revision 2, 
dated September 27, 2013. We have also revised paragraphs (c)(3) and 
(h)(2) of this proposed AD to refer to Boeing Alert Service Bulletin 
767-21A0247, Revision 1, dated April 9, 2013.
    In addition, we removed paragraph (k) of the proposed AD (in the 
NPRM), ``Credit for Previous Actions,'' from this proposed AD because 
operators that have accomplished the actions in Boeing Service Bulletin 
767-21-0245, dated April 16, 2010; or Boeing Alert Service Bulletin 
767-21A0245, Revision 1, dated September 30, 2010; must do additional 
work when accomplishing the procedures specified in Boeing Alert 
Service Bulletin 767-21A0245, Revision 2, dated September 27, 2013. We 
have redesignated paragraph (j) of the proposed AD (in the NPRM), 
``Concurrent Requirements,'' as paragraph (k)(1) of this proposed AD. 
In addition, we have added a new paragraph (k)(2) to this proposed AD 
to address the concurrent actions (relay installation and related 
wiring changes) identified in Boeing Alert Service Bulletin 767-
21A0247, Revision 1, dated April 9, 2013.
    Also since the issuance of the NPRM, we have reviewed Boeing Alert 
Service Bulletin 767-21A0254, dated June 7, 2013 (which was not 
referenced in the NPRM). Boeing Alert Service Bulletin 767-21A0254, 
dated June 7, 2013, describes procedures for installing the FDARS and 
activating the 3-way valve control logic change for certain Model 767-
300F series airplanes. We have redesignated paragraph (g) of the 
proposed AD (in the NPRM) as paragraph (g)(1) of this proposed AD, and 
added a new paragraph (g)(2) to this proposed AD to require the actions 
in Boeing Alert Service Bulletin 767-21A0254, dated June 7, 2013.

Comments

    We gave the public the opportunity to comment on the NPRM. The 
following presents the comments received on the NPRM and the FAA's 
response to each comment.

Request To Clarify the Applicability of the Proposed AD (in the NPRM)

    Boeing requested we state that the proposed AD (in the NPRM) does 
not apply to Model 767-300 (passenger) series airplanes. Boeing 
explained that the 3-way valve control logic for Model 767-300 
(passenger) series airplanes is significantly different from the 3-way 
valve control logic for Model 767-300F and Model 767-300BCF (Boeing 
Converted Freighter) series airplanes. Boeing indicated that, on Model 
767-300 (passenger) series airplanes, pack air (which is a moisture 
source on the freighter airplanes) to the flight deck instruments and 
equipment is rarely used. Boeing added that Model 767-300 (passenger) 
series airplanes only utilize airplane pack air during override and 
fuel jettison modes, and there have not been reports of moisture-
related display blanking on these airplanes.
    We find that clarification is necessary. This proposed AD applies 
to Model 767-300 and 767-300F series airplanes, as identified in 
certain service information. ``Model 767-300 series airplanes'' could 
include both passenger and BCF series airplanes. According to the U.S. 
type certificate data sheet for Model 767 airplanes, a Model 767-300BCF 
series airplane is a Model 767-300 (passenger) series airplane that has 
been modified in accordance with specific service information to 
operate in a freighter configuration. The service information 
identified in the applicability of this proposed AD addresses Model 
767-300BCF series airplanes and Model 767-300F series airplanes--not 
passenger airplanes. Therefore, this proposed AD does not apply to 
Model 767-300 (passenger) series airplanes. We have added this 
clarification to paragraphs (c), (i), and (k)(3) of this proposed AD.

Request To Revise the Proposed AD (in the NPRM) To Remove Certain 
Service Information References

    Boeing asked that all references to Boeing Service Bulletin 767-21-
0240 be removed from the NPRM, including the applicability statement. 
Boeing stated that the intent of this service information is to 
incorporate display improvements on Model 767-300BCF series airplanes. 
Boeing has confirmed that the actions to prevent display unit blanking 
included in Boeing Service Bulletin 767-21-0240 have already been 
incorporated on Model 767-300BCF series airplanes during the 
conversion, prior to re-delivery.
    Boeing also asked that all references to Boeing Service Bulletin 
767-21-0244 be removed from the NPRM, including the applicability 
statement. Boeing stated that the intent of this service information is 
also to incorporate display improvements on Model 767-300BCF series 
airplanes. Boeing has confirmed that the actions to prevent display 
unit blanking included in Boeing Service Bulletin 767-21-0244 have 
already been incorporated on Model 767-300BCF series airplanes in 
advance of this proposed AD.
    Since Boeing Service Bulletin 767-21-0240 has been incorporated on 
the affected airplanes during the conversion and prior to re-delivery, 
we agree with the commenter's request to remove references to that 
service bulletin from this proposed AD. Paragraph (c) of this proposed 
AD has been revised to omit Boeing Service Bulletin 767-21-0240, 
Revision 1, dated November 12, 2009, from paragraph (c)(1), and 
subsequent subparagraphs in paragraph (c) have been redesignated 
accordingly.
    However, we do not agree with the commenter's request to remove 
references to Boeing Service Bulletin 767-21-0244 from this proposed 
AD. The commenter has not submitted documentation to the FAA for 
verification that the affected operators of Model 767-300BCF series 
airplanes have accomplished the actions to prevent display unit 
blanking that are included in Boeing Service Bulletin 767-21-0244, 
Revision 1, dated March 8, 2010. Therefore, Boeing Service Bulletin 
767-21-0244, Revision 1, dated March 8, 2010, is still referenced in 
this proposed AD.
    Paragraph (h)(3) of the proposed AD (in the NPRM) has been omitted 
from this proposed AD because it referred to Boeing Service Bulletin 
767-21-0240, Revision 1, dated November 12, 2009 (which affects 
airplanes on which the service information has been done during the 
conversion and prior to re-

[[Page 33614]]

delivery), and the airplanes identified in this service information 
have been removed from the applicability of this proposed AD, as 
explained previously. However, the requirements for the remaining Model 
767-300BCF series airplanes (i.e., those subject to accomplishment of 
Boeing Service Bulletin 767-21-0244) have been moved from paragraph 
(h)(3) of the proposed AD (in the NPRM) to new paragraph (i) of this 
proposed AD. Paragraph (k) of this proposed AD, which correlates to 
paragraph (j) of the proposed AD (in the NPRM), has been revised to 
remove the concurrent requirements for Model 767-300BCF series 
airplanes identified in Boeing Service Bulletin 767-21-0240, Revision 
1, dated November 12, 2009. The concurrent requirements for Model 767-
300BCF series airplanes identified in Boeing Service Bulletin 767-21-
0244, Revision 1, dated March 8, 2010, are retained in paragraph (k)(3) 
of this proposed AD.

Request To Clarify the Requirements of the Proposed AD (in the NPRM)

    Boeing requested that the requirements of the proposed AD for Model 
767-300BCF versus Model 767-300F series airplanes be clarified. Boeing 
stated that the intended function of the 3-way valve control logic 
change is to provide moisture control to mitigate display blanking; 
however, the intended function of the FDARS is to mitigate the noise 
that resulted from the 3-way valve control logic change, not to control 
moisture and mitigate display blanking. Boeing stated that the proposed 
3-way valve control logic change and addition of the FDARS should be 
required for Model 767-300F series airplanes, and only the 3-way valve 
control logic change should be required for Model 767-300BCF series 
airplanes.
    We agree to clarify the requirements of this proposed AD. In light 
of the commenter's remarks, we revised paragraphs (g)(1) and (g)(2) of 
this proposed AD to state that, for Model 767-300F series airplanes, 
the required actions include the installation of an FDARS and 
activation of or change to the 3-way valve control logic. We also 
revised the heading for paragraph (g) of this proposed AD accordingly.
    In addition, we revised paragraphs (h)(1) and (h)(2) of this 
proposed AD to state that, for Model 767-300F series airplanes 
identified in Boeing Alert Service Bulletin 767-21A0245, Revision 2, 
dated September 27, 2013, and Boeing Alert Service Bulletin 767-
21A0247, Revision 1, dated April 9, 2013, respectively, the required 
actions include a change of the 3-way valve control logic and MCADS, 
and installation of an FDARS. We also revised the heading for paragraph 
(h) of this proposed AD accordingly.
    As previously discussed, a new paragraph (i) is included in this 
proposed AD. This paragraph specifies that, for Model 767-300BCF series 
airplanes, only the installation of the 3-way valve control logic and 
flight deck display equipment cooling system is required. The 
subsequent paragraphs have been redesignated accordingly.

Request To Revise the Number of Affected Airplanes

    Boeing requested that the number of affected airplanes be changed 
from 43 to 58. Boeing stated that based on its current records of 
operators, there are 58 Model 767-300F series airplanes of U.S. 
registry.
    Based on the number of affected Model 767-300 and 767-300F series 
airplanes currently on the U.S. Register, we changed the number of 
affected airplanes to 52 in the ``Costs of Compliance'' section of this 
SNPRM. We also made additional changes to the ``Costs of Compliance'' 
section to account for any added requirement of this proposed AD.

Effect of Winglets on Accomplishment of the Proposed Actions

    Aviation Partners Boeing stated that the installation of winglets 
per Supplemental Type Certificate (STC) ST01920SE (http://rgl.faa.gov/
Regulatory_and_Guidance_Library/rgstc.nsf/0/
59027f43b9a7486e86257b1d006591ee/$FILE/ST01920SE.pdf) does not affect 
the accomplishment of the manufacturer's service instructions.
    We agree with the commenter that STC ST01920SE (http://rgl.faa.gov/
Regulatory_and_Guidance_Library/rgstc.nsf/0/
59027f43b9a7486e86257b1d006591ee/$FILE/ST01920SE.pdf) does not affect 
the accomplishment of the manufacturer's service instructions. 
Therefore, the installation of STC ST01920SE does not affect the 
ability to accomplish the actions required by this AD. We have not 
changed this SNPRM in this regard.

Additional Change Made to This Proposed AD

    We incorrectly referred to the original issue date of Boeing 
Service Bulletin 767-21-0235 as July 29, 2011, throughout the NPRM. We 
have specified the correct date of the original issue of Boeing Service 
Bulletin 767-21-0235 as October 8, 2009, in paragraphs (j) and (k) of 
this proposed AD.

    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation Programs'' 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
