Plain English Summary

2/10 complexity

What this is

This is an Airworthiness Directive — a mandatory safety rule issued by the Civil Aviation Safety Authority for owners and operators of DH 87 Hornet Moth aeroplanes (a vintage, single-engine biplane).

What you must do

You must modify the aircraft's seat restraints by fitting a proper safety harness (a restraint system that secures the occupant with straps across the shoulders and torso, not just a lap belt) for each seat.

How to comply

The installation must follow a specific scheme that has been formally approved by the Secretary (the relevant government aviation official). For technical guidance on how to design and approve this scheme, see Airworthiness Advisory Circular No. 62 and its amendment in Circular No. 63.

Why this matters

This ensures pilots and passengers are securely restrained during turbulence or emergency situations, significantly improving safety compared to basic lap belts.
