Airworthiness Directive · Amendment 39-18292 · Wing ribs/bulkhead
Piper Aircraft, Inc. Airplanes
Superseded. A later AD replaced this one: AD 2016-07-21. Comply with the one in force.
This AD applies to Piper Aircraft, Inc. Model PA-28-161 airplanes, serial numbers 2842393 through 2842395; Model PA-28-181 airplanes, serial numbers 2843769 through 2843775 and 2843779 through 2843791; and Model PA-28R-201 airplanes, serial number 2844152, certificated in any category.
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-28-161, PA-28-181, and PA-28R-201 airplanes. This AD requires inspecting the right wing rib at wing station 140.09 for cracks and taking necessary corrective action. This AD was prompted by a report of cracks found in the wing rib bead radius that were formed during production. We are issuing this AD to correct the unsafe condition on these products.
(1) Within the next 25 hours time-in-service after October 29, 2015 (the effective date of this AD), inspect the right wing rib at wing station (WS) 140.09 for cracks following the INSTRUCTIONS section of Piper Aircraft, Inc. Service Bulletin No. 1279, dated August 26, 2015.
(2) If any crack is detected during the inspection required by paragraph (g)(1) of this AD, before further flight, obtain and implement an FAA-approved repair scheme, approved specifically for this AD. At the operator's discretion, assistance may be provided by contacting Piper Aircraft, Inc. at the address identified in paragraph (k)(3) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
