14 CFR Part 39
[Docket No. FAA-2013-0362; Directorate Identifier 2013-NM-030-AD;
Amendment 39-17531; AD 2013-15-15]

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
The Boeing Company Model 727 airplanes. This AD was prompted by an
evaluation by the design approval holder indicating that the frame-to-
floor beam attachment is subject to widespread fatigue damage. This AD
requires repetitive high frequency eddy current inspections for any
crack of the frames at body station (STA) 188 through STA 344, and
repair if necessary. We are issuing this AD to detect and correct
fatigue cracking at the frame-to-floor beam attachment, on both the
left- and right-sides, which could result in reduced structural
integrity of the airplane, and decompression of the cabin.
DATES: This AD is effective September 20, 2013.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of September 20,
2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
The NPRM published in the Federal Register on May 3, 2013 (78 FR
25905). The NPRM proposed to require repetitive high frequency eddy
current inspections for any crack of the frames at body STA 188 through
STA 344, and repair if necessary.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comments received.
Boeing stated that it supports the NPRM (78 FR 25905, May 3, 2013).
Fedex stated that the NPRM (78 FR 25905, May 3, 2013) will be
effective for twenty of its Model 727-200 airplanes, the inspection
threshold and intervals will fit within its planned scheduled
maintenance checks and therefore will be no impact to available lift,
the number of man-hours and elapsed time to accomplish the inspections
will not impact the overall span-time of its planned scheduled
maintenance check, and the inspections do not require any special
inspection techniques, training, or tooling.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
thisAD as proposed--except for minor editorial changes. We have
determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (78 FR 25905, May 3, 2013) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 25905, May 3, 2013).

Costs of Compliance
We estimate that this AD affects 106 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspection................ 118 work-hours x $85 $0 $10,030 per $1,063,180 per
per hour = $10,030 inspection cycle. inspection cycle.
per inspection cycle.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in 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.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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):
2013-15-15 The Boeing Company: Amendment 39-17531; Docket No. FAA-
2013-0362; Directorate Identifier 2013-NM-030-AD.
(a) Effective Date
This AD is effective September 20, 2013.
(b) Affected ADs
None.
(c) Applicability
This AD applies to The Boeing Company Model 727, 727C, 727-100,
727-100C, 727-200, and 727-200F series airplanes, certificated in
any category, as identified in Boeing Special Attention Service
Bulletin 727-53-0234, dated January 17, 2013.
(d) Subject
Joint Aircraft System Component (JASC)/Air Transport Association
(ATA) of America Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by an evaluation by the design approval
holder indicating that the frame-to-floor beam attachment is subject
to widespread fatigue damage. We are issuing this AD to detect and
correct fatigue cracking at the frame-to-floor beam attachment, on
both the left- and right-sides, which could result in reduced
structural integrity of the airplane, and decompression of the
cabin.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Inspection and Repair
Before the accumulation of 61,000 total flight cycles, or within
24 months after the effective date of this AD, whichever occurs
later, do a high frequency eddy current inspection for cracking of
the frames (for certain stations), in the area of the floor beam
attachments on both the left- and right-sides of the airplane, in
accordance with the Accomplishment Instructions of Boeing Special
Attention Service Bulletin 727-53-0234, dated January 17, 2013.
Repeat this inspection thereafter at intervals not to exceed 20,000
flight cycles. If any crack is found during any inspection required
by this AD, before further flight, repair the crack using a method
approved in accordance with the procedures specified in paragraph
(h) of this AD.
(h) Alternative Methods of Compliance (AMOCs)
(1) The Manager, Seattle Aircraft Certification Office (ACO),
FAA, has the authority to approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19. In accordance with 14
CFR 39.19, send your request to your principal inspector or local
Flight Standards District Office, as appropriate. If sending
information directly to the manager of the ACO, send it to the
attention of the person identified in the Related Information
section of this AD. Information may be emailed to: [email protected].
(2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the local flight standards district office/certificate holding
district office.
(3) An AMOC that provides an acceptable level of safety may be
used for any repair required by this AD if it is approved by the
Boeing Commercial Airplanes Organization Designation Authorization
(ODA) that has been authorized by the Manager, Seattle ACO, to make
those findings. For a repair method to be approved, the repair must
meet the certification basis of the airplane, and the approval must
specifically refer to this AD.
