[FR Doc. 2013–19528 Filed 8–12–13; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2012–1069; Directorate Identifier 2012–NM–044–AD] RIN 2120–AA64 Airworthiness Directives; the Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. AGENCY: We are revising an earlier proposed airworthiness directive (AD), for all The Boeing Company Model 727 airplanes, which proposed to supersede an existing AD. That NPRM proposed to retain repetitive inspections of the intank fuel boost pump wiring, installation of sleeving over the in-tank fuel boost pump wires, repetitive inspections of a certain electrical wire, sleeve, and conduit, and applicable investigative and corrective actions; and repetitive engine fuel suction feed operational tests. That NPRM proposed to also require replacement of the wire SUMMARY: PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 49217 bundles for the wing and center fuel boost pumps, installation of convoluted liners, and related investigative and corrective actions if necessary. That NPRM also proposed to require replacement of the fuel quantity indicating system (FQIS) wires; a lowfrequency eddy current inspection for cracking; and repair if necessary. That NPRM also proposed to require revising the maintenance program to incorporate changes to the airworthiness limitations section. That NPRM was prompted by a report of damage found to the sleeve, jacket, and insulation on an electrical wire during a repetitive inspection. This action revises that NPRM by revising certain compliance times, specifying a terminating action, and adding a proposed requirement to incorporate another change to the airworthiness limitations section. We are proposing this supplemental NPRM to prevent chafing of the fuel boost pump electrical wiring and leakage of fuel into the conduit, and to prevent electrical arcing between the wiring and the surrounding conduit, which could result in arcthrough of the conduit, and consequent fire or explosion of the fuel tank. 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 supplemental NPRM by September 27, 2013.

That NPRM published in the Federal Register on October 11, 2012 (77 FR 61731). That NPRM proposed to retain repetitive inspections of the intank fuel boost pump wiring to detect chafing of the wire insulation, evidence of electrical arcing, or arc-through of the conduit wall, and applicable corrective VerDate Mar<15>2010 15:30 Aug 12, 2013 Jkt 229001 action; and installation of sleeving over the in-tank fuel boost pump wires. That NPRM also proposed to retain repetitive inspections for damage of a certain electrical wire and sleeve, and arcing damage of the conduit and signs of fuel leakage into the conduit; applicable investigative and corrective actions; and repetitive engine fuel suction feed operational tests. That NPRM proposed to require replacement of the wire bundles for the wing and center fuel boost pumps with new, improved wire bundles, installation of convoluted liners, and related investigative and corrective actions if necessary. That NPRM also proposed to require replacement of the FQIS wires with new, improved wires; a low-frequency eddy current inspection for cracking; and repair if necessary. That NPRM also proposed to require revising the maintenance program to incorporate changes to the airworthiness limitations section. after accomplishing the actions specified in Boeing Alert Service Bulletin 727–28A013, dated August 18, 2010, which is proposed in paragraph (m) of this supplemental NPRM. Actions Since Previous NPRM (77 FR 61731, October 11, 2012) Was Issued Since we issued the previous NPRM (77 FR 61731, October 11, 2012), we have determined that additional limitations are necessary and that the initial compliance time for one task must be reduced. The preamble to AD 2007–11–08, Amendment 39–15065 (72 FR 28594, May 22, 2007) explains that we consider the requirements ‘‘interim action’’ and were considering further rulemaking. We now have determined that further rulemaking is indeed necessary, and this proposed AD follows from that determination. Change to Compliance Time Paragraph (n) of the previous NPRM (77 FR 61731, October 11, 2012) specified a compliance time of 60 months after the effective date of the AD for accomplishing the initial task for Airworthiness Limitation Instruction (ALI) Task 28–AWL–20, ‘‘Fuel Boost Pump Wires in Conduit Installation—In Fuel Tank;’’ and CDCCL Task 28–AWL– 21, ‘‘Fuel Boost Pump Wires in Conduit Installation—In Fuel Tank,’’ of Section B of Boeing 727–100/200 Airworthiness Limitations (AWLs), D6–8766–AWL, Revision August 2010. We have added paragraph (n)(2) to this supplemental NPRM to change the compliance time for accomplishing the initial task to within 72 months after accomplishing the actions specified in Boeing Service Bulletin 727–28A0133, dated October 5, 2011. Comments We gave the public the opportunity to comment on the NPRM (77 FR 61731, October 11, 2012). The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Add Airworthiness Limitations Boeing requested that we add ALI Task 28–AWL–18, ‘‘Fuel Quantity Indicating System (FQIS)—Out-Tank Wiring Lightning Shield to Ground Termination,’’ and Critical Design Configuration Control Limitation (CDCCL) Task 28–AWL–19, ‘‘Fuel Quantity Indicating System (FQIS)— Out-Tank Wiring Lightning Shield to Ground Termination’’ to the original NPRM (77 FR 61731, October 11, 2012). We agree with the request. We have added new paragraph (n)(1) in this supplemental NPRM to require revising the maintenance program to include both tasks. These AWL’s are necessary PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 Request for Correction Boeing requested that we correct the Relevant Service Information section and paragraph (n) of the NPRM (77 FR 61731, October 11, 2012) to refer to Section B rather than Section 9 of Boeing 727–100/200 Airworthiness Limitations (AWLs), D6–8766–AWL, Revision August 2010. Boeing stated that there is no section 9 in that document. We agree with the request. Although the Relevant Service Information is not repeated in this supplemental NPRM, we have made the correction to new paragraph (n)(2) of this supplemental NPRM (which was paragraph (n) of the previous NPRM (77 FR 61731, October 11, 2012)). FAA’s Determination We are proposing this supplemental NPRM 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 previous NPRM (77 FR 61731, October 11, 2012). As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this supplemental NPRM. Proposed Requirements of the Supplemental NPRM This supplemental NPRM would require accomplishing the actions E:\FR\FM\13AUP1.SGM 13AUP1 49219 Federal Register / Vol. 78, No. 156 / Tuesday, August 13, 2013 / Proposed Rules specified in the service information described previously, except as discussed under ‘‘Differences Between the Supplemental NPRM and the Service Information.’’ Differences Between the Supplemental NPRM and the Service Information Although Boeing Alert Service Bulletin 727–28A0133, dated October 5, 2011, specifies that operators may contact the manufacturer for disposition of certain repair conditions, this proposed AD would require operators to repair those conditions using a method approved in accordance with the procedures specified in paragraph (p) of this AD. Costs of Compliance We estimate that this proposed AD affects 569 airplanes of U.S. registry.We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Inspection, test, and corrective actions [retained actions from existing AD 2007–11–08, Amendment 39–15065 (72 FR 28594, May 22, 2007)].

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 proposed 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 15:30 Aug 12, 2013 Cost on U.S. operators Cost per product We have received no definitive data that would enable us to provide a cost estimate for the on-condition actions specified in this proposed AD. VerDate Mar<15>2010 Number of U.S. airplanes Parts cost Jkt 229001 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. PO 00000 Frm 00018 Fmt 4702 Sfmt 4702 § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): ■ The Boeing Company: Docket No. FAA– 2012–1069; Directorate Identifier 2012– NM–044–AD. (a) Comments Due Date We must receive comments by September 27, 2013. (b) Affected ADs This AD supersedes AD 2007–11–08, Amendment 39–15065 (72 FR 28594, May 22, 2007). (c) Applicability (1) This AD applies to all The Boeing Company Model 727, 727C, 727–100, 727– 100C, 727–200, and 727–200F series airplanes, certificated in any category. (2) This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections) and/or Critical Design Configuration Control Limitations (CDCCLs). Compliance with these actions and/or CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (p) of this AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane.

Model J–2 airplanes equipped with wing lift struts. AD 99– SUMMARY: VerDate Mar<15>2010 15:30 Aug 12, 2013 Jkt 229001 26–19 currently requires repetitively inspecting the wing lift struts for dents and corrosion; repetitively inspecting the wing lift strut forks for cracks; replacing any dented or corroded wing lift strut; replacing any cracked wing lift strut fork; and repetitively replacing the wing lift strut forks at specified times for certain airplanes. AD 99–26–19 also currently requires incorporating a ‘‘NO STEP’’ placard on the wing lift strut. Since we issued AD 99–26–19, we have been informed that paragraph (c) is being misinterpreted and causing confusion. This proposed AD would clarify the intent of the language currently in paragraph (c) of AD 99–26– 19 and would retain all other requirements of AD 99–26–19.

(currently Piper Aircraft, Inc.) J–2 series airplanes equipped with wing lift struts. We issued AD 99–26– 19 because J–2 series airplanes were inadvertently omitted from the applicability of AD 99–01–05, Amendment 39–10972 (63 FR 72132, December 31, 1998, (‘‘99–01–05’’). AD 99–01–05 was issued to supersede AD 93–10–06, Amendment 39–8586 (58 FR 29965, May 25, 1993), which previously included J–2 series airplanes in the Applicability section, in order to include a terminating action for repetitively inspecting and replacing the wing lift struts and the wing lift strut forks. We issued both ADs to detect and correct corrosion and cracking on the front and rear wing lift struts and forks, which could cause the wing lift strut to fail. This failure could result in the wing separating from the airplane. E:\FR\FM\13AUP1.SGM 13AUP1

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 all The Boeing Company Model 727 airplanes, which proposed to 
supersede an existing AD. That NPRM proposed to retain repetitive 
inspections of the in-tank fuel boost pump wiring, installation of 
sleeving over the in-tank fuel boost pump wires, repetitive inspections 
of a certain electrical wire, sleeve, and conduit, and applicable 
investigative and corrective actions; and repetitive engine fuel 
suction feed operational tests. That NPRM proposed to also require 
replacement of the wire bundles for the wing and center fuel boost 
pumps, installation of convoluted liners, and related investigative and 
corrective actions if necessary. That NPRM also proposed to require 
replacement of the fuel quantity indicating system (FQIS) wires; a low-
frequency eddy current inspection for cracking; and repair if 
necessary. That NPRM also proposed to require revising the maintenance 
program to incorporate changes to the airworthiness limitations 
section. That NPRM was prompted by a report of damage found to the 
sleeve, jacket, and insulation on an electrical wire during a 
repetitive inspection. This action revises that NPRM by revising 
certain compliance times, specifying a terminating action, and adding a 
proposed requirement to incorporate another change to the airworthiness 
limitations section. We are proposing this supplemental NPRM to prevent 
chafing of the fuel boost pump electrical wiring and leakage of fuel 
into the conduit, and to prevent electrical arcing between the wiring 
and the surrounding conduit, which could result in arc-through of the 
conduit, and consequent fire or explosion of the fuel tank. 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 supplemental NPRM by September 
27, 2013.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    We issued an NPRM to amend 14 CFR part 39 to include an AD that 
would apply to to all Boeing Model 727, 727C, 727-100, 727-100C, 727-
200, and 727-200F series airplanes, certificated in any category. That 
NPRM published in the Federal Register on October 11, 2012 (77 FR 
61731). That NPRM proposed to retain repetitive inspections of the in-
tank fuel boost pump wiring to detect chafing of the wire insulation, 
evidence of electrical arcing, or arc-through of the conduit wall, and 
applicable corrective action; and installation of sleeving over the in-
tank fuel boost pump wires. That NPRM also proposed to retain 
repetitive inspections for damage of a certain electrical wire and 
sleeve, and arcing damage of the conduit and signs of fuel leakage into 
the conduit; applicable investigative and corrective actions; and 
repetitive engine fuel suction feed operational tests. That NPRM 
proposed to require replacement of the wire bundles for the wing and 
center fuel boost pumps with new, improved wire bundles, installation 
of convoluted liners, and related investigative and corrective actions 
if necessary. That NPRM also proposed to require replacement of the 
FQIS wires with new, improved wires; a low-frequency eddy current 
inspection for cracking; and repair if necessary. That NPRM also 
proposed to require revising the maintenance program to incorporate 
changes to the airworthiness limitations section.

Actions Since Previous NPRM (77 FR 61731, October 11, 2012) Was Issued

    Since we issued the previous NPRM (77 FR 61731, October 11, 2012), 
we have determined that additional limitations are necessary and that 
the initial compliance time for one task must be reduced. The preamble 
to AD 2007-11-08, Amendment 39-15065 (72 FR 28594, May 22, 2007) 
explains that we consider the requirements ``interim action'' and were 
considering further rulemaking. We now have determined that further 
rulemaking is indeed necessary, and this proposed AD follows from that 
determination.

Comments

    We gave the public the opportunity to comment on the NPRM (77 FR 
61731, October 11, 2012). The following presents the comments received 
on the NPRM and the FAA's response to each comment.

Request To Add Airworthiness Limitations

    Boeing requested that we add ALI Task 28-AWL-18, ``Fuel Quantity 
Indicating System (FQIS)--Out-Tank Wiring Lightning Shield to Ground 
Termination,'' and Critical Design Configuration Control Limitation 
(CDCCL) Task 28-AWL-19, ``Fuel Quantity Indicating System (FQIS)--Out-
Tank Wiring Lightning Shield to Ground Termination'' to the original 
NPRM (77 FR 61731, October 11, 2012).
    We agree with the request. We have added new paragraph (n)(1) in 
this supplemental NPRM to require revising the maintenance program to 
include both tasks. These AWL's are necessary after accomplishing the 
actions specified in Boeing Alert Service Bulletin 727-28A013, dated 
August 18, 2010, which is proposed in paragraph (m) of this 
supplemental NPRM.

Request for Correction

    Boeing requested that we correct the Relevant Service Information 
section and paragraph (n) of the NPRM (77 FR 61731, October 11, 2012) 
to refer to Section B rather than Section 9 of Boeing 727-100/200 
Airworthiness Limitations (AWLs), D6-8766-AWL, Revision August 2010. 
Boeing stated that there is no section 9 in that document.
    We agree with the request. Although the Relevant Service 
Information is not repeated in this supplemental NPRM, we have made the 
correction to new paragraph (n)(2) of this supplemental NPRM (which was 
paragraph (n) of the previous NPRM (77 FR 61731, October 11, 2012)).

Change to Compliance Time

    Paragraph (n) of the previous NPRM (77 FR 61731, October 11, 2012) 
specified a compliance time of 60 months after the effective date of 
the AD for accomplishing the initial task for Airworthiness Limitation 
Instruction (ALI) Task 28-AWL-20, ``Fuel Boost Pump Wires in Conduit 
Installation--In Fuel Tank;'' and CDCCL Task 28-AWL-21, ``Fuel Boost 
Pump Wires in Conduit Installation--In Fuel Tank,'' of Section B of 
Boeing 727-100/200 Airworthiness Limitations (AWLs), D6-8766-AWL, 
Revision August 2010. We have added paragraph (n)(2) to this 
supplemental NPRM to change the compliance time for accomplishing the 
initial task to within 72 months after accomplishing the actions 
specified in Boeing Service Bulletin 727-28A0133, dated October 5, 
2011.

FAA's Determination

    We are proposing this supplemental NPRM 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 
previous NPRM (77 FR 61731, October 11, 2012). As a result, we have 
determined that it is necessary to reopen the comment period to provide 
additional opportunity for the public to comment on this supplemental 
NPRM.

Proposed Requirements of the Supplemental NPRM

    This supplemental NPRM would require accomplishing the actions

[[Page 49219]]

specified in the service information described previously, except as 
discussed under ``Differences Between the Supplemental NPRM and the 
Service Information.''

Differences Between the Supplemental NPRM and the Service Information

    Although Boeing Alert Service Bulletin 727-28A0133, dated October 
5, 2011, specifies that operators may contact the manufacturer for 
disposition of certain repair conditions, this proposed AD would 
require operators to repair those conditions using a method approved in 
accordance with the procedures specified in paragraph (p) of this AD.

Costs of Compliance

    We estimate that this proposed AD affects 569 airplanes of U.S. 
registry.We estimate the following costs to comply with this proposed 
AD:

                                                                     Estimated Costs

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 proposed 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

The Boeing Company: Docket No. FAA-2012-1069; Directorate Identifier 
2012-NM-044-AD.

(a) Comments Due Date

    We must receive comments by September 27, 2013.

(b) Affected ADs

    This AD supersedes AD 2007-11-08, Amendment 39-15065 (72 FR 
28594, May 22, 2007).

(c) Applicability

    (1) This AD applies to all The Boeing Company Model 727, 727C, 
727-100, 727-100C, 727-200, and 727-200F series airplanes, 
certificated in any category.
    (2) This AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections) and/or Critical 
Design Configuration Control Limitations (CDCCLs). Compliance with 
these actions and/or CDCCLs is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired 
in the areas addressed by this AD, the operator may not be able to 
accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according 
to paragraph (p) of this AD. The request should include a 
description of changes to the required actions that will ensure the 
continued operational safety of the airplane.

[[Page 49220]]

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 28, Fuel.

(e) Unsafe Condition

    This AD was prompted by a report of damage found to the sleeve, 
jacket, and insulation on an electrical wire during a repetitive 
inspection. We are issuing this AD to prevent chafing of the fuel 
boost pump electrical wiring and leakage of fuel into the conduit, 
and to prevent electrical arcing between the wiring and the 
surrounding conduit, which could result in arc-through of the 
conduit, and consequent fire or explosion of the fuel tank.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Retained Compliance Times

    This paragraph restates the requirements of paragraphs (f), (g), 
and (h) of AD 2007-11-08, Amendment 39-15065 (72 FR 28594, May 22, 
2007).
    (1) For airplanes with 50,000 or more total flight hours as of 
June 28, 1999 (the effective date of AD 99-12-52, Amendment 39-11199 
(64 FR 33394, June 23, 1999)): Within 20 days after June 28, 1999,
