Plain English Summary

2/10 complexity

What this does: This directive mandates a safety upgrade for all Ryan ST Series aircraft. Owners must modify the seat restraint systems to install proper safety harnesses (shoulder straps, not just lap belts) to better protect occupants during accidents or sudden stops.

Who it affects: Anyone who owns or operates a Ryan ST Series aeroplane.

What must be done: The aircraft owner must fit safety harnesses to the seats following an installation plan (called a "scheme") that has been formally approved by the Secretary (the senior government official responsible for aviation safety). Guidelines for creating this installation plan are available in Airworthiness Advisory Circular No. 62 from March 1972.

Why it matters: This prevents passengers and pilots from being thrown forward or ejected during turbulence, crashes, or hard landings. The deadline for completing this work was 1 January 1974.
