SUPPLEMENTARY INFORMATION: 

Discussion

    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.

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 inspection of the aft wing spars with repair as 
necessary.

Interim Action

    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.

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 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

[[Page 37173]]

be approved and available shortly after publication of this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
              Action                      Labor cost             Parts cost           product        operators
----------------------------------------------------------------------------------------------------------------
Inspection of the aft wing spars..  11 work-hours x $85    Not applicable.......            $935         $33,660
                                     per hour = $935.
----------------------------------------------------------------------------------------------------------------

    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.

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.
