What this does: This is a safety mandate requiring operators of DHC-6 Twin Otter aircraft to upgrade the pilot seatbelts to full safety harnesses.

Key requirements:

The modification: Each front (pilot) seat must be fitted with a proper safety harness restraint system (not just a simple lap belt).

Guidelines: Installation guidance is available in Airworthiness Advisory Circular No. 62 (March 1972).
Deadline: The work had to be completed before 1 October 1973.

Why it matters: This improves pilot protection during turbulence, hard landings, or accidents by ensuring pilots remain properly secured at their controls.
