Airworthiness Directive · Amendment 39-9584 · Aviat Aircraft Inc. Models S-2A, S-2B, and S-2S Airplanes (Formerly Pitts Models S-2A, S-2B, and S-2S Airplanes)
Aviat Aircraft Inc. Models S-2A, S-2B, and S-2S Airplanes (Formerly Pitts Models S-2A, S-2B, and S-2S Airplanes)
Superseded. A later AD replaced this one: AD 96-09-08 R1. Comply with the one in force.
Models S-2A, S-2B, and S-2S airplanes (formerly Pitts Models S-2A, S-2B, and S-2S airplanes), all serial numbers, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to Aviat Aircraft Inc., Models S-2A, S-2B, and S-2S airplanes (formerly Pitts Models S-2A, S-2B, and S-2S airplanes). This action requires inspecting the longerons aft of the rear cabane struts for cracks, and if cracked, prior to further flight, repairing the cracks. Reports of longeron failure caused by fatigue aft of the rear cabane struts prompted this action. The actions specified by this AD are intended to prevent cracking and subsequent failure of the longerons resulting in possible loss of control of the airplane.
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.
