AD/DHA-3/26 - Front Seat Restraint Installation - Modification - CANCELLED

What this document does

This officially cancels an old aviation safety rule that applied to DHA-3 Drover aircraft (a small Australian-made aeroplane from the 1950s-60s).

What was the old rule?

Back in 1972, the Civil Aviation Safety Authority required owners of Drover aircraft (certified before 1967) to install upper torso restraints — essentially shoulder harnesses or seatbelts — on front seats to protect pilots and passengers during crashes.

What changed?

As of 17 January 2008, this specific rule for Drovers no longer exists. Owners should instead follow a general safety directive called AD/GENERAL/74 Amendment 1, which applies to all aircraft types, not just Drovers.

Who does this affect?

Owners and operators of DHA-3 Drover series aircraft. They must now comply with the general directive rather than this specific one.
