Airworthiness Directives; M7 Aerospace LLC Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all M7 
Aerospace LLC Models SA226-AT, SA226-T, SA226-T(B), SA226-TC, SA227-AC 
(C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, SA227-DC (C-26B), SA227-
TT, SA26-AT, and SA26-T airplanes. This AD was

[[Page 15658]]

prompted by reports of airplanes with multiple fatigue cracks in the FS 
69.31 front pressure bulkhead. This AD requires repetitively inspecting 
(visually) the FS 51.31 front pressure bulkhead on SA26 series 
airplanes and FS 69.31 front pressure bulkhead on SA226 and SA227 
series airplanes for cracks, and repairing any cracked bulkhead; this 
AD also requires reporting certain inspection results to M7 Aerospace 
LLC. We are issuing this AD to correct the unsafe condition on these 
products.

DATES: This AD is effective April 25, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 25, 
2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all M7 Aerospace LLC Models 
SA226-AT, SA226-T, SA226-T(B), SA226-TC, SA227-AC (C-26A), SA227-AT, 
SA227-BC (C-26A), SA227-CC, SA227-DC (C-26B), SA227-TT, SA26-AT, and 
SA26-T airplanes. The NPRM published in the Federal Register on 
December 24, 2013 (78 FR 77618). The NPRM was prompted by reports of 
airplanes with multiple fatigue cracks in the FS 69.31 front pressure 
bulkhead. The NPRM proposed to require repetitively inspecting 
(visually) the FS 51.31 front pressure bulkhead on SA26 series 
airplanes and FS 69.31 front pressure bulkhead on SA226 and SA227 
series airplanes for cracks, and repairing any cracked bulkhead. This 
NPRM also proposed to require reporting certain inspection results to 
M7 Aerospace LLC. We are issuing this AD to correct the unsafe 
condition on these products.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 77618, December 24, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data 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 77618, December 24, 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 77618, December 24, 2013).

Costs of Compliance

    We estimate that this AD affects 360 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800

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.
