Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2006-22-15 for 
all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 
747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 
747SP series airplanes. AD 2006-22-15 required repetitive inspections 
for cracking of certain panel webs and stiffeners of the nose wheel 
well (NWW), and corrective actions if necessary; and replacement of 
certain panels with new panels, which terminates the repetitive 
inspections. This new AD reduces a compliance time and adds certain 
inspections and an applicable repair. This AD was prompted by multiple 
reports of fatigue cracking in the NWW top panel and side panel webs 
and stiffeners. We are issuing this AD to prevent fatigue cracking of 
the NWW side and top panels, which could result in a NWW 
depressurization event severe enough to reduce the structural integrity 
of the fuselage.

DATES: This AD is effective April 22, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 22, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to supersede AD 2006-22-15, Amendment 39-14812 (71 
FR 64884, November 6, 2006) (``AD 2006-22-15''). AD 2006-22-15 applied 
to all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-
200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, 
and 747SP series airplanes. The SNPRM published in the Federal Register 
on September 18, 2015 (80 FR 56407) (``the SNPRM''). We preceded the 
SNPRM with a notice of proposed rulemaking (NPRM) that published in the 
Federal Register on November 17, 2014 (79 FR 68388) (``the NPRM''). The 
NPRM proposed to continue to require repetitive inspections for 
cracking of

[[Page 14708]]

certain panel webs and stiffeners of the NWW, and corrective actions if 
necessary; and replacement of certain panels with new panels, which 
terminates the repetitive inspections. The NPRM proposed to reduce a 
compliance time and add certain inspections and repair if necessary. 
The NPRM was prompted by reports of fatigue cracking in the panel webs 
and stiffeners of the NWW found prior to the inspection threshold of AD 
2006-22-15. The SNPRM revised the NPRM by specifying a repetitive 
inspection interval for a certain NWW area inspection. We are issuing 
this AD to prevent fatigue cracking of the NWW side and top panels, 
which could result in a NWW depressurization event severe enough to 
reduce the structural integrity of the fuselage.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the SNPRM and 
the FAA's response to each comment.

Support for the SNPRM

    Two commenters supported the SNPRM. One commenter stated that the 
FAA should continue to execute its administrative power to ensure 
traveler safety and industry compliance, adding that while the original 
rule was good, ensuring that specifics are covered and timetables are 
available is an important improvement.

Request for Credit for Compliance Times in Previously Approved 
Alternative Methods of Compliance (AMOCs)

    Boeing requested that we allow credit for the compliance times in 
previously approved AMOCs, if the compliance times are acceptable 
according to the SNPRM.
    We agree with the commenter's request. We have revised paragraph 
(p)(4) of this AD to state that: AMOC actions approved previously for 
AD 2006-22-15 are approved as AMOCs for the corresponding actions of 
this AD. In addition, paragraph (p)(4) of this AD states that the 
compliance times in AMOCs approved previously for AD 2006-22-15 are not 
approved for the corresponding actions and compliance times in this AD, 
if this AD specifies an earlier compliance time than that specified in 
AD 2006-22-15; and that compliance times in AMOCs approved previously 
for AD 2006-22-15 that meet the requirements of this AD are acceptable.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the change described previously and minor editorial 
changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the SNPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed the following Boeing service bulletins.
    <bullet> Boeing Alert Service Bulletin 747-53A2808, dated November 
30, 2012. This service information describes procedures for replacement 
of the side and top panel webs, support beams, and stiffeners of the 
NWW; an inspection for cracking of the attaching structural elements 
that are common to the removed top and side panels of the NWW; 
repetitive post-modification inspections for cracks in the top and side 
panel webs and stiffeners; and repairs.
    <bullet> Boeing Service Bulletin 747-53A2465, Revision 5, dated 
July 11, 2013. This service information describes procedures for doing 
inspections for cracking of the NWW side panel and top panel webs and 
longitudinal stiffeners for cracks, and related investigative and 
corrective actions.
    <bullet> Boeing Service Bulletin 747-53A2562, Revision 3, dated 
July 11, 2013. This service information describes procedures for 
replacement of the side and top panel webs and certain stiffeners of 
the NWW; an inspection for cracks in attaching structural elements that 
are common to the removed top panel and side panels; repetitive post-
modification inspections for cracks in the top and side panel webs and 
stiffeners; and repairs.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

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

[[Page 14709]]

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.

(p) 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 paragraph (q)(1) of this AD. 
Information may be emailed to: <a href="/cdn-cgi/l/email-protection#665f4b27282b4b35030712120a034b2725294b272b29254b34031713031512152600070748010910"><span class="__cf_email__" data-cfemail="dbe2f69a9596f688bebaafafb7bef69a9894f69a969498f689beaaaebea8afa89bbdbabaf5bcb4ad">[email&#160;protected]</span></a>.
    (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, modification, or alteration 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. To be approved, the 
repair method, modification deviation, or alteration deviation must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
    (4) AMOC actions approved previously for AD 2006-22-15 are 
approved as AMOCs for the corresponding actions of this AD. The 
compliance times in AMOCs approved previously for AD 2006-22-15 are 
not approved for the corresponding actions and compliance times in 
this AD, if this AD specifies an earlier compliance time than that 
specified in AD 2006-22-15. Compliance times in AMOCs approved 
previously for AD 2006-22-15 that meet the requirements of this AD
