14 CFR Part 39

[Docket No. FAA-2013-0302; Directorate Identifier 2013-NM-019-AD; 
Amendment 39-17503; AD 2013-13-15]
RIN 2120-AA64


Airworthiness Directives; the Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding airworthiness directive (AD) 87-02-07, 
which applied to all The Boeing Company Model 737-100 and -200 series 
airplanes. AD 87-02-07 required replacement of certain underwing fuel 
tank access covers with stronger, fire-resistant covers. This new AD 
also requires inspecting fuel tank access doors to determine that 
impact-resistant access doors are installed in the correct locations, 
inspecting application of stencils and index markers of impact-
resistant access doors, doing corrective actions if necessary, revising 
the maintenance program, and adding airplanes to the applicability. 
This AD was prompted by reports of standard access doors installed 
where impact-resistant access doors are required, and reports of 
impact-resistant doors without stencils. We are issuing this AD to 
prevent foreign object penetration of the wing tank, which could lead 
to a fuel leak near ignition sources (engine, hot brakes), consequently 
leading to a fuel-fed fire.

DATES: This AD is effective August 20, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of August 20, 
2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 87-02-07, Amendment 39-5506 (Docket No. 86-NM-
175-AD; 52 FR 518, January 7, 1987), (``AD 87-02-07''). AD 87-02-07 
applied to the specified products. The NPRM published in the Federal 
Register on April 10, 2013 (78 FR 21279). The NPRM proposed to continue 
to require replacement of certain underwing fuel tank access covers 
with stronger, fire-resistant covers. The NPRM also proposed to require 
inspecting fuel tank access doors to determine that impact-resistant 
access doors are installed in the correct

[[Page 42416]]

locations, inspecting application of stencils and index markers of 
impact-resistant access doors, doing corrective actions if necessary, 
revising the maintenance program, and adding airplanes to the 
applicability.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received.

Concurrence With NPRM (78 FR 21279, April 10, 2013)

    Boeing stated that it concurs with the content of the NPRM (78 FR 
21279, April 10, 2013).

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD 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 21279, April 10, 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 21279, April 10, 2013).

Costs of Compliance

    We estimate that this AD affects 128 airplanes of U.S. registry.
    We estimate the following costs 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

    We have determined that 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

access doors to determine that impact-resistant access doors are 
installed in the correct locations, and an inspection for proper 
application of stencils and index markers of impact-resistant access 
doors; and do all applicable corrective actions; in accordance with 
the Accomplishment Instructions of Boeing Service Bulletin 737-28-

100/200/200C/300/400/500 Airworthiness Limitations (AWLs) and 
Certification Maintenance Requirements (CMRs), Document D6-38278-
CMR, Revision August 2012.

(i) No Alternative Critical Design Configuration Control Limitations 
(CDCCLs)

    After accomplishing the revision required by paragraph (h) of 
this AD, no alternative CDCCLs may be used unless the CDCCLs are 
approved as an alternative method of compliance (AMOC) in accordance 
with the procedures specified in paragraph (j) of this AD.

(j) 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: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (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.
