SUPPLEMENTARY INFORMATION:
Background The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 to supersede AD 790103, Amendment 393383 44 FR 36, January 2, 1979, Docket No. 78EA69 AD 79
0103 and AD 832003, Amendment 394739 48 FR 45535, October 6, 1983, Docket No. 83CE23AD AD 8320
03. AD 790103 applied to certain Piper Model PA36285 airplanes and required repetitive inspections of spar carry through assembly part number

P/N 9737000, with repair as necessary, until the spar carry through assembly is replaced with P/N 76824
02. AD 832003 applied to Piper Models PA36285, PA36300, and PA36375 airplanes and established life limits for certain wing structural components.
The NPRM published in the Federal Register on March 23, 2021 86 FR
15439. The NPRM was prompted by inconsistencies between the two ADs and the airplanes type certificate. The FAA determined that the life limits for the spar carry through assembly, P/N
9737000 or 7682402, were inadvertently omitted from AD 8320
03 for certain airplanes. In the NPRM, the FAA proposed to add the life limit for the spar carry through assembly for Models PA36285 and PA36300
airplanes, serial numbers 367660123
through 368160023; and Model PA
36375 airplanes, serial numbers 36
7802001 through 368302025. The FAA
also determined the repetitive inspections of the spar carry through assembly required by AD 790103
should apply to both Model PA36285
and Model PA36300 airplanes until the life limit replacement of the spar carry through assembly with P/N
7682402. In the NPRM, the FAA also proposed to require adding the repetitive inspections for the Model PA
36300 airplanes. After the initial life limit replacement of the wing spar carry through assembly, P/N 9737000 with P/N 7682402, the repetitive inspections will no longer be required.
The FAA is issuing this AD to address the unsafe condition on these products.
Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs.
Conclusion The FAA reviewed the relevant data and determined that air safety requires adoption of the AD as proposed.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these products. This AD is adopted as proposed in the NPRM.
