What this directive does

This Airworthiness Directive (AD) — a legally binding safety order — requires owners and operators of specific Piper Comanche aircraft to install safety wiring on the control tube guide blocks.

Who is affected

This applies only to:

Models: Piper PA-24 and PA-24-250
Serial numbers: 24-80 through 24-1367

What must be done

The aircraft must be modified by fitting safety wiring (a mechanical method using wire to lock bolts in place and prevent them from loosening) to the control tube guide blocks, following the instructions in Piper Service Bulletin No. 178.

Why this matters

Control tubes carry the pilot's control inputs (steering, pitch) to the aircraft's control surfaces. If the guide blocks fail or loosen, the pilot could lose control of the aircraft. This wiring ensures these critical parts stay secure during flight.
