Plain English Summary

2/10 complexity

This Airworthiness Directive mandates a safety upgrade for specific aircraft.

What it requires: Owners must modify the front seat restraint systems in Piper PA-24 Comanche aeroplanes by installing an approved safety harness (seatbelt and shoulder harness system). The installation must follow a design scheme approved by the Secretary (the senior government official responsible for aviation safety at the time).

Who it affects: All owners and operators of Piper PA-24 series aircraft, regardless of specific model variant.

Why it matters: This ensures pilots and front passengers have proper upper-body restraint during turbulence, hard landings, or accidents—significantly improving survival chances compared to basic lap belts alone.

Compliance deadline: The modification must be completed before 1 September 1972.
