14 CFR Part 39
[Docket No. FAA-2012-1319; Directorate Identifier 2012-NM-179-AD]
RIN 2120-AA64
Airworthiness Directives; the Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to revise an existing airworthiness directive (AD)
that applies to all The Boeing Company Model 757 airplanes. The
existing AD currently requires revising the maintenance program by
incorporating new and revised fuel tank system limitations in the
Airworthiness Limitations (AWLs) section of the Instructions for
Continued Airworthiness; and requires the initial inspection of certain
repetitive AWL inspections to phase-in those inspections, and repair if
necessary. Since we issued that AD, we have found errors in paragraph
references in the existing AD. This proposed AD would revise those
paragraph references to refer to the correct paragraphs. We are
proposing this AD to prevent the potential for ignition sources inside
fuel tanks caused by latent failures, alterations, repairs, or
maintenance actions, which in combination with flammable fuel vapors,
could result in a
[[Page 6248]]
fuel tank explosion and consequent loss of the airplane.

Discussion
On June 6, 2012, we issued AD 2012-12-15, Amendment 39-17095 (77 FR
42964, July 23, 2012), for all The Boeing Company Model 757 airplanes.
That AD superseded AD 2008-10-11, Amendment 39-15517 (73 FR 25974, May
8, 2008). AD 2012-12-15 requires revising the maintenance program by
incorporating new and revised fuel tank system limitations in the
Airworthiness Limitations (AWLs) section of the Instructions for
Continued Airworthiness to satisfy Special Federal Aviation Regulation
No. 88 requirements; and requires the initial inspection of certain
repetitive AWL inspections to phase-in those inspections, and repair if
necessary. That AD resulted from a report that an AWL required by a
previous AD must be revised. We issued that AD to prevent the potential
for ignition sources inside fuel tanks caused by latent failures,
alterations, repairs, or maintenance actions, which in combination with
flammable fuel vapors, could result in a fuel tank explosion and
consequent loss of the airplane.
Actions Since Existing AD Was Issued
Since we issued AD 2012-12-15, Amendment 39-17095 (77 FR 42964,
July 23, 2012), we have found errors in paragraph references in the
existing AD. The second sentence in paragraph (h)(1) of the existing AD
refers to paragraph (n) of that AD, which is a compliance time for AWL
No. 28-AWL-26. The correct reference should be to paragraph (l) of that
AD, which is a compliance time for AWL No. 28-AWL-03. The last sentence
in paragraph (l) of the existing AD refers to paragraph (h)(2) of that
AD, which is a definition of a detailed inspection. The correct
reference should be to paragraph (h)(1)(ii) of that AD, which
references a specific AWL and compliance time.
FAA's Determination
We are proposing this AD 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.
Proposed AD Requirements
This proposed AD would retain all requirements of AD 2012-12-15,
Amendment 39-17095 (77 FR 42964, July 23, 2012). This proposed AD would
revise certain paragraph references.
Costs of Compliance
We estimate that this proposed AD affects 639 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
AWLs revisions [retained actions 9 work-hours x $85 None............... $765 $488,835
from existing AD (AD 2012-12- per hour = $765.
15, Amendment 39-17095 (77 FR
42964, July 23, 2012))].
Inspections [retained actions 8 work-hours x $85 None............... 680 434,520
from existing AD (AD 2012-12- per hour = $680.
15, Amendment 39-17095 (77 FR
42964, July 23, 2012))].
----------------------------------------------------------------------------------------------------------------
The new requirements of this proposed AD add no additional economic
burden.
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,
[[Page 6249]]
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 have 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 that the 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 AD:
The Boeing Company: Docket No. FAA-2012-1319; Directorate Identifier
2012-NM-179-AD.
(a) Comments Due Date
The FAA must receive comments on this AD action by March 18,
2013.
(b) Affected ADs
This AD revises AD 2012-12-15, Amendment 39-17095 (77 FR 42964,
July 23, 2012). Certain requirements of this AD terminate certain
requirements of AD 2008-11-07, Amendment 39-15529 (73 FR 30755, May
29, 2008); AD 2008-06-03, Amendment 39-15415 (73 FR 13081, March 12,
2008); and AD 2009-06-20, Amendment 39-15857 (74 FR 12236, March 24,
2009).
(c) Applicability
(1) This AD applies to all The Boeing Company Model 757-200, -
00PF, -200CB, and -300 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 these inspections, 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 of an alternative method of compliance (AMOC)
according to paragraph (s) 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.
(d) Subject
Joint Aircraft System Component (JASC)/Air Transport Association
(ATA) of America Code 28: Fuel.
(e) Unsafe Condition
This AD results from a design review of the fuel tank systems.
The Federal Aviation Administration is issuing this AD to prevent
the potential for ignition sources inside fuel tanks caused by
latent failures, alterations, repairs, or maintenance actions,
which, in combination with flammable fuel vapors, could result in a
fuel tank explosion and consequent loss of the airplane.
(f) Compliance
You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
have already been done.
(g) Retained Revision of Airworthiness Limitations (AWLs) Section
This paragraph restates the requirements of paragraph (g) of AD
2012-12-15, Amendment 39-17095 (77 FR 42964, July 23, 2012). Before
December 16, 2008, revise the AWLs section of the Instructions for
Continued Airworthiness (ICA) by incorporating the information in
the subsections specified in paragraphs (g)(1) through (g)(3) of
this AD into the maintenance planning data (MPD) document; except
that the initial inspections specified in table 1 to paragraph
(h)(1) of this AD must be done at the compliance times specified in
table 1 to paragraph (h)(1) of this AD. Accomplishing the
requirements of paragraph (k) of this AD terminates the requirements
of this paragraph.
