Federal Aviation Administration (FAA), DOT.
Final rule; request for comments.
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) Model PA-46-600TP (M600) airplanes. This AD requires inspection of the aft wing spars with repair as necessary. This AD was prompted by a report from Piper of the aft wing spar cracking during wing assembly. We are issuing this AD to address the unsafe condition on these products.
This AD is effective August 9, 2017.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of August 9, 2017.
We must receive comments on this AD by September 25, 2017.
You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

We received a report from Piper of an aft wing spar cracking during wing assembly on a Model PA-46-600TP (M600) airplane. An investigation of the incident identified that the supplier may have delivered aft wing spars to Piper that did not conform to Piper's type design specifications and requirements. A quality escape during manufacturing resulted in an understrength part, and these nonconforming parts may have been installed on some of the affected airplanes. This condition, if not corrected, could result in failure of the aft wing spar and lead to wing separation with consequent loss of control. We are issuing this AD to correct the unsafe condition on these products.
Related Service Information Under 1 CFR Part 51
We reviewed Piper Aircraft, Inc. Service Bulletin No. 1317A, dated July 26, 2017. The service bulletin describes procedures for a visual inspection of the affected area and describes flight restrictions for allowing the optional special flight permit that allows a one-time flight to a facility capable of doing the inspections and repair required by this AD. 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.
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.
This AD requires inspection of the aft wing spars with repair as necessary.
We consider this AD interim action. We are coordinating with Piper on the development of inspection and repair procedures to address this unsafe condition.
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 notice and comment prior to adoption of this rule because failure of the aft wing spar could result in wing separation with consequent loss of control. 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.
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 final rule. Send your comments to an address listed under the ADDRESSES section. Include the Docket No. FAA-2017-0759 and Product Identifier 2017-CE-023-AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this final rule. We will consider all comments received by the closing date and may amend this final rule because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this final rule.
Costs of Compliance
We estimate that this AD affects 36 airplanes of U.S. registry.
We estimate the following costs to comply with this AD. Piper is currently developing the required inspection method, and the FAA anticipates it will Start Printed Page 37173be approved and available shortly after publication of this AD:
|Action||Labor cost||Parts cost||Cost per product||Cost on U.S. operators|
|Inspection of the aft wing spars||11 work-hours × $85 per hour = $935||Not applicable||$935||$33,660|
We have no way of knowing how many airplanes may need the repair based on the results of the required inspection. Since there is not an approved repair procedure, we have no way of knowing the cost of the required repair.
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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to small airplanes and domestic business jet transport airplanes to the Director of the Policy and Innovation Division.
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.Start List of Subjects
