This amendment supersedes Airworthiness Directive (AD) 93-10- 06, which currently requires repetitively inspecting the wing lift struts and wing lift strut forks for cracks or corrosion on all airplane models of The New Piper Aircraft, Inc. (Piper) that are equipped with wing lift struts, and replacing any strut or fork found cracked or corroded. This AD clarifies certain requirements of AD 93- 10-06, eliminates the lift strut fork repetitive inspection requirement on the Piper PA-25 series airplanes, incorporates models inadvertently omitted from AD 93-10-06, and requires fabricating and installing a placard on the lift strut. This AD results from reports, questions, and information received from the field on AD 93-10-06, which show a need to clarify and add information that will more fully achieve the safety intent of that AD. The actions specified by this AD are intended to prevent in-flight separation of the wing from the airplane caused by corroded wing lift struts or cracked wing lift forks, which could result in 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.
