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.

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

    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.

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.

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

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.
