Plain English Summary

2/10 complexity

This Airworthiness Directive (AD) requires owners and operators of specific Piper PA-25 Pawnee agricultural aircraft to modify a structural component called the jury strut (a support brace for the wing).

Who it affects:

Owners of Piper PA-25 aircraft with serial numbers 25-1 through 25-399 (early production models)

What must be done:

Carry out a modification to the jury strut exactly as specified in Piper Service Letter No. 403
The aircraft manufacturer provides the technical instructions; this directive legally mandates compliance with those instructions

When:

Before 1 September 1971 (historical deadline)

Why it matters: Airworthiness Directives are legally binding safety orders issued by the Civil Aviation Safety Authority. This directive addresses a structural integrity issue with the wing support. Operating the aircraft without completing this modification would violate aviation law and compromise safety.
