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 M7 Aerospace LLC Models SA227–AT, SA227–AC, SA227–BC, SA227–CC, and SA227–DC airplanes equipped with a bayonet shear pin main cabin door latching mechanism. The NPRM published in the Federal Register on May 14, 2014 (79 FR 27505). The NPRM was prompted by reports of fatigue cracking of the main cabin door surround structure. Investigation revealed that the fatigue cracks are related to a change in loading due to design changes in the door surround structure and the door latching system. 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 42661 received no comments on the NPRM (79 FR 27505, May 14, 2014) 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. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (79 FR 27505, May 14, 2014) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 27505, May 14, 2014). Costs of Compliance We estimate that this AD affects 250 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Threshold high frequency eddy current (HFEC)/low frequency eddy current (LFEC)/detailed visual inspection. 2.5 work-hours × $85 per hour = $212.50. Not Applicable ................. $212.50 $53,125 We estimate the following costs to do any necessary repairs that will be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these repairs: ON-CONDITION COSTS Action Labor cost Parts cost Cost per product Repair Installation ......................................................... 48 work-hours × $85 per hour = $4,080 ...................... $6,670 $10,750 mstockstill on DSK4VPTVN1PROD with RULES 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 VerDate Mar<15>2010 17:54 Jul 22, 2014 Jkt 232001 should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information Collection Clearance Officer, AES–200. 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 PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 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, E:\FR\FM\23JYR1.SGM 23JYR1 42662 Federal Register / Vol. 79, No. 141 / Wednesday, July 23, 2014 / Rules and Regulations (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.

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 the specified products. The NPRM was published in the Federal Register on April 10, 2014 (79 FR 19844). The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: There have been reports of damage in excess of acceptable criteria to the highpressure fuel line from the P&WC PW150A engine flowmeter to the flow divider. Damage has included fretting wear through contact with the engine igniter cables. The contact is the result of incorrectly routed igniter cables. While there has been no report of associated fuel leakage, the fretting wear, if undetected, could progress to a point where highpressure fuel would leak into the engine nacelle. Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. E:\FR\FM\23JYR1.SGM 23JYR1

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 M7 
Aerospace LLC Models SA227-AT, SA227-AC, SA227-BC, SA227-CC, and SA227-
DC airplanes equipped with a bayonet shear pin main cabin door latching 
mechanism. This AD was prompted by fatigue cracks found in the internal 
door surround doubler, the fuselage external skin, and the door corner 
fittings at the fuselage upper forward corner of the main cabin door 
cutout. This AD requires repetitively inspecting the four corners of 
the main cabin door cutout for cracks, making necessary repairs, and 
reporting inspection results to M7 Aerospace LLC. We are issuing this 
AD to correct the unsafe condition on these products.

DATES: This AD is effective August 27, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 27, 
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 M7 Aerospace LLC Models 
SA227-AT, SA227-AC, SA227-BC, SA227-CC, and SA227-DC airplanes equipped 
with a bayonet shear pin main cabin door latching mechanism. The NPRM 
published in the Federal Register on May 14, 2014 (79 FR 27505).
    The NPRM was prompted by reports of fatigue cracking of the main 
cabin door surround structure. Investigation revealed that the fatigue 
cracks are related to a change in loading due to design changes in the 
door surround structure and the door latching system. 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 (79 FR 27505, May 14, 
2014) 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. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 27505, May 14, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 27505, May 14, 2014).

Costs of Compliance

    We estimate that this AD affects 250 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 Independence Ave. SW., Washington, DC 20591. ATTN: Information 
Collection Clearance Officer, AES-200.

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,

[[Page 42662]]

    (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.
