FAA AD Differences Note 1: This AD differs from the MCAI and/or service information as follows: No differences. Other FAA AD Provisions Reason (e) The mandatory continuing airworthiness information (MCAI) states: There have been several in-service reports of finding trapped water on the bottom of the cockpit windshield frames (or lower windshield frames) that resulted in either corrosion or water ingress into the cockpit. In one occurrence, the trapped water caused severe corrosion of numerous anchor nuts that secure the windshield to the lower windshield frame, such that the intended fastening function was seriously compromised. Corrosion of the lower windshield frames, including the anchor nuts that secure the windshield to the aircraft structure, can result in a serious structural degradation possibly leading to the loss of the windshield during flight. Also, water could leak into the cockpit and cause either a malfunction or failure of the electrical and electronics systems in the area of the cockpit instrument panels. * corrective actions, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 8–53–78, Revision D, dated July 6, 2010 (for Model DHC–8–101, –102, –103, –106, –201, –202, –301, –311, and –315 airplanes); or 84–53–43, dated April 27, 2010 (for Model DHC–8–401 and –402 airplanes); except where these service bulletins state to contact the manufacturer, contact the New York Aircraft Certification Office or Transport Canada Civil Aviation (TCCA) or its delegated agent.

VerDate Mar<15>2010 16:25 Apr 29, 2011 Jkt 223001 SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. That NPRM published in the Federal Register on December 28, 2010 (75 FR 81508). That NPRM proposed to require, for certain airplanes, replacing certain boost pump relays with ground fault interrupter (GFI) relays. For certain other airplanes, that NPRM proposed to require installing new panels in the main equipment center, making certain wiring changes, installing new GFI relays in the new panels, and installing new electrical load management system (ELMS) software. For certain other airplanes, that NPRM proposed to require doing certain bond resistance measurements, and corrective actions if necessary. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal and the FAA’s response to each comment. Boeing supported the NPRM. Request to Extend Compliance Time American Airlines (AAL) requested that we extend the compliance time in paragraphs (g) and (h) of the NPRM for the work done in accordance with Boeing Service Bulletin 777–28A0037, Revision 2, dated September 20, 2010, from 36 months to 60 months. AAL stated that they have already accomplished Boeing Service Bulletin 777–28A0037, Revision 1, dated June 15, 2009, on 75 percent of their Model 777 fleet. The proposed 36-month compliance time would require special scheduling for those airplanes. AAL proposed that the compliance time for all actions in the NPRM be extended to 60 months to be consistent with the 60month compliance time in paragraph (i) of the NPRM for the GFI relay replacement for the main tank boost pumps specified in Boeing Service Bulletin 737–28A0038, Revision 1, dated September 20, 2010. We disagree with the request to extend the compliance time for the actions required by paragraphs (g) and (h) of the NPRM (bond resistance measurements and the installation of new panels, new fuel pump control GFI relays, software, and wiring changes). In developing appropriate compliance times for those actions, we considered the safety implications and practical aspects of accomplishing these actions PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 within a period of time that corresponds to the normal scheduled maintenance for most affected operators. In consideration of these items, we have determined that a 36-month compliance time will ensure an acceptable level of safety and allow those actions to be done during scheduled maintenance intervals for most affected operators. However, under the provisions of paragraph (k) of this AD, we will consider requests for approval of an alternative method of compliance (AMOC) if sufficient data are submitted to substantiate that the request would provide an acceptable level of safety. We have not changed this AD in this regard. Request To Delay Rule Pending Release of New Service Bulletins Japan Airlines (JAL) requested that we delay the issuance of this AD until Boeing and GE Aviation publish new revisions to their service information (referenced in the NPRM) to include certain changes. JAL stated these changes are to correct or add numbers for wires, modules, connectors, and figures. JAL also stated that, in addition, certain GE Aviation service information also needed to be revised to add another procedure to install labels or separate the labels from the conversion kit. JAL explained that when it receives the labels as part of the conversion kit, the remaining shelf life of the labels is not adequate to allow the labels to be installed on the airplanes. JAL is concerned that, unless the service information is revised, these issues could delay incorporation of this AD or result in multiple AMOC requests. JAL stated that they are in communication with Boeing and GE Aviation in regard to these issues with the service information. We agree with JAL’s concerns about the shelf life of the labels possibly affecting operators’ ability to comply with this AD within the required compliance times. This AD requires all actions, including labeling, in the Accomplishment Instructions of Boeing Service Bulletins 777–28A0038, Revision 1; and 777–28A0037, Revision 2; both dated September 20, 2010; to be accomplished. We have added paragraph (j) to this AD to provide an optional method of labeling panels. However, we disagree with the request to delay this AD until Boeing and GE Aviation issue revised service information to correct or add numbers for wires, modules, connectors, and figures. No data or information to justify that request was provided. However, under the provisions of paragraph (k) of this AD, we will consider requests for E:\FR\FM\02MYR1.SGM 02MYR1 24347 Federal Register / Vol. 76, No. 84 / Monday, May 2, 2011 / Rules and Regulations an AMOC if sufficient data are submitted to substantiate that the change would provide an acceptable level of safety. We have not changed the AD in this regard. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD burden on any operator or increase the scope of the AD. with the change described previously and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic Costs of Compliance We estimate that this AD will affect 130 airplanes of U.S. registry. The following table provides the estimated costs for U.S. operators to comply with this AD.

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. jlentini on DSKJ8SOYB1PROD with RULES Jkt 223001 Number of U.S.registered airplanes Cost per product 3 $85 $25,577 $25,832 126 3 85 52,545 52,800 0 4 85 37,257 37,597 4 4 85 17,816 18,156 0 76 85 29,934 36,394 130 (2) Is not a ‘‘significant rule’’ under 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.

Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal and the FAA’s response to each comment. Support for the NPRM Boeing supported the contents of the NPRM. Request To Include References to Airplane Maintenance Manual United Airlines (UAL) stated that it is concerned about the actions in Boeing Alert Service Bulletin 747–54A2232, dated April 15, 2010, being undone and leading to the same condition. UAL suggested that we revise the NPRM to include airplane maintenance manual (AMM) references, including a check for marker BAC27EPP667 before installing the access door. As an alternative, UAL also suggested that the mid-pivot access door part number could be changed instead of keeping the same part number. UAL stated that if the NPRM is not changed to incorporate one of the two options, then the required actions could be undone if doors without the marker are installed. We disagree with the request to revise this AD. Section 39.7 of the Federal Aviation Regulations (14 CFR 39.7) states the following: ‘‘Anyone who operates a product that does not meet the requirements of an applicable airworthiness directive is in violation of this section.’’ Therefore, operators are prohibited from installing a door that does not meet the requirements of this AD. However, operators are permitted to add a check to applicable AMM to prevent installing the incorrect access door. We have not changed the final rule in regard to this issue.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
the specified products. That NPRM published in the Federal Register on 
December 28, 2010 (75 FR 81508). That NPRM proposed to require, for 
certain airplanes, replacing certain boost pump relays with ground 
fault interrupter (GFI) relays. For certain other airplanes, that NPRM 
proposed to require installing new panels in the main equipment center, 
making certain wiring changes, installing new GFI relays in the new 
panels, and installing new electrical load management system (ELMS) 
software. For certain other airplanes, that NPRM proposed to require 
doing certain bond resistance measurements, and corrective actions if 
necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
and the FAA's response to each comment. Boeing supported the NPRM.

Request to Extend Compliance Time

    American Airlines (AAL) requested that we extend the compliance 
time in paragraphs (g) and (h) of the NPRM for the work done in 
accordance with Boeing Service Bulletin 777-28A0037, Revision 2, dated 
September 20, 2010, from 36 months to 60 months. AAL stated that they 
have already accomplished Boeing Service Bulletin 777-28A0037, Revision 
1, dated June 15, 2009, on 75 percent of their Model 777 fleet. The 
proposed 36-month compliance time would require special scheduling for 
those airplanes. AAL proposed that the compliance time for all actions 
in the NPRM be extended to 60 months to be consistent with the 60-month 
compliance time in paragraph (i) of the NPRM for the GFI relay 
replacement for the main tank boost pumps specified in Boeing Service 
Bulletin 737-28A0038, Revision 1, dated September 20, 2010.
    We disagree with the request to extend the compliance time for the 
actions required by paragraphs (g) and (h) of the NPRM (bond resistance 
measurements and the installation of new panels, new fuel pump control 
GFI relays, software, and wiring changes). In developing appropriate 
compliance times for those actions, we considered the safety 
implications and practical aspects of accomplishing these actions 
within a period of time that corresponds to the normal scheduled 
maintenance for most affected operators. In consideration of these 
items, we have determined that a 36-month compliance time will ensure 
an acceptable level of safety and allow those actions to be done during 
scheduled maintenance intervals for most affected operators. However, 
under the provisions of paragraph (k) of this AD, we will consider 
requests for approval of an alternative method of compliance (AMOC) if 
sufficient data are submitted to substantiate that the request would 
provide an acceptable level of safety. We have not changed this AD in 
this regard.

Request To Delay Rule Pending Release of New Service Bulletins

    Japan Airlines (JAL) requested that we delay the issuance of this 
AD until Boeing and GE Aviation publish new revisions to their service 
information (referenced in the NPRM) to include certain changes. JAL 
stated these changes are to correct or add numbers for wires, modules, 
connectors, and figures. JAL also stated that, in addition, certain GE 
Aviation service information also needed to be revised to add another 
procedure to install labels or separate the labels from the conversion 
kit. JAL explained that when it receives the labels as part of the 
conversion kit, the remaining shelf life of the labels is not adequate 
to allow the labels to be installed on the airplanes. JAL is concerned 
that, unless the service information is revised, these issues could 
delay incorporation of this AD or result in multiple AMOC requests. JAL 
stated that they are in communication with Boeing and GE Aviation in 
regard to these issues with the service information.
    We agree with JAL's concerns about the shelf life of the labels 
possibly affecting operators' ability to comply with this AD within the 
required compliance times. This AD requires all actions, including 
labeling, in the Accomplishment Instructions of Boeing Service 
Bulletins 777-28A0038, Revision 1; and 777-28A0037, Revision 2; both 
dated September 20, 2010; to be accomplished. We have added paragraph 
(j) to this AD to provide an optional method of labeling panels. 
However, we disagree with the request to delay this AD until Boeing and 
GE Aviation issue revised service information to correct or add numbers 
for wires, modules, connectors, and figures. No data or information to 
justify that request was provided. However, under the provisions of 
paragraph (k) of this AD, we will consider requests for

[[Page 24347]]

an AMOC if sufficient data are submitted to substantiate that the 
change would provide an acceptable level of safety. We have not changed 
the AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the change described previously and minor editorial 
changes. We have determined that these minor changes:
     [Agr]re consistent with the intent that was proposed in 
the NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Costs of Compliance

    We estimate that this AD will affect 130 airplanes of U.S. 
registry. The following table provides the estimated costs for U.S. 
operators to comply with this AD.

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

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.
