AD/RYAN/2 - Seat Restraint Installations - Modifications - CANCELLED

What this does: This document cancels a previous aircraft safety rule about seatbelts for Ryan ST series aeroplanes.

Who it affects: Owners and operators of Ryan ST series aircraft (a type of vintage light aircraft).

What it means:

• A 1972 rule that required shoulder harnesses (upper torso restraints) in these aircraft is now cancelled.
• The cancellation took effect on 17 January 2008.
• The safety requirements haven't disappeared—they've been moved to a general rule covering multiple aircraft types (AD/GENERAL/74 Amendment 1).
• If you own one of these planes, you no longer need to follow this specific document; check the general directive instead for harness requirements.
