Abstract
The FAA is superseding Airworthiness Directive (AD) 79-01-03, which applied to certain Piper Aircraft, Inc. (Piper) Model PA-36-285 airplanes, and AD 83-20-03, which applied to Piper Models PA-36-285, PA-36-300, and PA-36-375 airplanes. AD 79-01-03 required repetitive inspections of the spar carry through assembly until replaced with a different part numbered spar carry through assembly. AD 83-20-03 established life limits for the wing spar structural components. This AD retains the requirements in AD 79-01-03 and AD 83-20-03 and requires the spar carry through assembly inspection from AD 79-01-03 for additional airplanes and adds life limits for certain wing structural components previously omitted from AD 83-20-03 for certain serial numbered airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
