(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.
Unsafe condition
This AD was prompted by reports of cracks found in the wing rib on airplanes outside the Applicability, paragraph (c), of AD 2015-20-13. The cracks occurred in production during forming of the wing rib bead radius. We are issuing this AD to detect and correct cracks in the wing rib, which if not corrected, could result in reduced structural integrity of the wing with consequent loss of control.
Affected ADs
This AD replaces AD 2015-20-13, Amendment 39-18292 (80 FR 61725) (“AD 2015-20-13”).
