We are superseding Airworthiness Directive (AD) 2015-20-13 for certain Piper Aircraft, Inc. Models PA-28-161, PA-28-181, and PA-28R- 201 airplanes. AD 2015-20-13 required inspecting the right wing rib at wing station 140.09 for cracks and taking necessary corrective action. This AD retains the actions for AD 2015-20-13 and adds airplanes to the applicability. This AD was prompted by reports that additional airplanes have been found with the same cracks. We are issuing this AD to correct the unsafe condition on these products.
(1) Inspect the right wing rib at wing station (WS) 140.09 for cracks at the following compliance times.
(i) For airplanes previously affected by AD 2015-20-13: Within the next 25 hours time-in-service after (TIS) after October 29, 2015 (the effective date retained from AD 2015-20-13) following the INSTRUCTIONS section of Piper Aircraft, Inc. Service Bulletin No. 1279, dated August 26, 2015, or Piper Aircraft, Inc. Service Bulletin No. 1279A, dated March 3, 2016.
(ii) For airplanes new to this AD: Within the next 25 hours TIS after April 26, 2016 (the effective date of this AD) following the INSTRUCTIONS section of Piper Aircraft, Inc. Service Bulletin No. 1279A, dated March 3, 2016.
(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)(5) 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.
