Airworthiness Directive · Amendment 39-9645 · Aviat Aircraft, Inc. Models S-1S, S-1T, S-2, S-2A, S-2S, and S-2B Airplanes (Formerly Known as Pitts Models S- 1S, S-1T, S-2, S-2A, S-2S, and S-2B Airplanes)
Aviat Aircraft, Inc. Models S-1S, S-1T, S-2, S-2A, S-2S, and S-2B Airplanes (Formerly Known as Pitts Models S- 1S, S-1T, S-2, S-2A, S-2S, and S-2B Airplanes)
Superseded. A later AD replaced this one: AD 96-12-03 R1. Comply with the one in force.
Models S-1S, S-1T, S-2, S-2A, S-2S, and S-2B airplanes (formerly known as Pitts Models S-1S, S-1T, S-2, S-2A, S-2S, and S-2B airplanes), all serial numbers, certificated in any category, that are equipped with aft lower fuselage wing attach fittings incorporating part number (P/N) 76090, 2-2107-1, or 1-210-102, and where these aft lower fuselage wing attach fittings on both wings have not been modified in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Aviat Service Bulletin (SB) No. 25, dated April 3, 1996.
This amendment adopts a new airworthiness directive (AD) that applies to certain Aviat Aircraft, Inc. (Aviat) Models S-1S, S-1T, S-2, S-2A, S-2S, and S-2B airplanes that are equipped with aft lower fuselage wing attach fittings incorporating either part number (P/N) 76090, 2-2107-1, or 1-210-102. This action requires repetitively inspecting the aft lower fuselage wing attach fitting on both wings for cracks and modifying any cracked aft lower fuselage wing attach fitting. Modifying the aft lower fuselage wing attach fitting on both wings eliminates the repetitive inspection requirement of the AD. Several reports of cracked fuselage wing attach fittings on the affected airplanes prompted this action. The actions specified by this AD are intended to prevent possible in-flight separation of the wing from the airplane caused by a cracked fuselage wing attach fitting.
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.
