Airworthiness Directives; M7 Aerospace LLC Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
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-BC (C-26A), SA227-CC, SA227-DC (C-26B), SA227-AT, and SA227-TT airplanes. This AD requires repetitively inspecting the left and right forward (main) and aft spar wing-to-fuselage attach fittings for cracks and replacing any cracked fitting. This AD also requires reporting certain inspection results to the FAA. This AD was prompted by reports of fatigue cracking in the left and right forward (main) spar wing-to-fuselage attach fittings. We are issuing this AD to correct the unsafe condition on these products.
DATES: The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of September 21, 2012.

We must receive comments on this AD by October 22, 2012.

SUPPLEMENTARY INFORMATION: Discussion

We have received reports of premature fatigue cracks found in the left and right forward (main) spar wing-to-fuselage attach fittings on M7 Aerospace LLC SA226 and SA227 airplanes. Each airplane is equipped with two attach fittings on the forward (main) spar and two on the aft spar on the left and right side of the airplane. An owner/operator of five of the affected airplanes had the left and right forward (main) spar wing-to-fuselage attach fittings inspected, and all five airplanes had cracks in at least one of the attach fittings. On the 5 airplanes, a total of 20 left and right forward (main) spar wing-to-fuselage attach fittings were inspected; 7 of those were found with cracks. The cracks found emanate from the end pad fastener holes to the free edge of the pad and in the fillet radii of the upper outboard corner on both fitting halves.

M7 Aerospace LLC has included inspection of the aft spar attach fittings in the service information since they are similar to the forward fittings in design and experience equivalent load cycles.

This condition, if not corrected, could result in failure of the wing-to-fuselage attach fitting, which could cause the wing to separate from the airplane.

Relevant Service Information

We reviewed M7 Aerospace LLC SA226 Series Service Bulletin 226-53-016, dated July 27, 2012, with Supplement A—SB 226-53-016, dated June 22, 2012; SA227 Series Service Bulletin 227-53-010, dated July 27, 2012, with Supplement A—SB 227-53-010, dated June 22, 2012; and SA227 Series Service Bulletin CC7-53-006, dated July 27, 2012, with Supplement A—SB CC7-53-006 dated June 22, 2012. The service information describes procedures for repetitively inspecting the left and right forward (main) and aft spar wing-to-fuselage attach fittings for cracks and replacing any cracked fitting.

FAA's Determination

We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

AD Requirements

This AD requires accomplishing the actions specified in the service information described previously. This AD also requires sending certain inspection results to the FAA.

FAA's Justification and Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving noticeand comment prior to adoption of this rule because cracks in the wing-to-fuselage attach fittings could cause the fitting to fail, which could result in wing separation from the airplane. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under theADDRESSESsection. Include the docket number FAA-2012-0917 and Directorate Identifier 2012-CE-030-AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.

We will post all comments we receive, without change, tohttp://www.regulations.gov,including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

Costs of Compliance

We estimate that this AD affects 330 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 Inspect the left and right forward (main) and aft spar wing-to-fuselage attach fittings for cracks 52 work-hours × $85 per hour = $4,420 per inspection cycle Not applicable $4,420 per inspection cycle $1,458,600 per inspection cycle.

We estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need this replacement:

On-Condition Costs Action Labor cost Parts cost Cost per product Replace cracked wing-to-fuselage attach fitting pair 100 work-hours × $85 per hour = $8,500 $3,600 $12,100 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.
