Plain English Summary

1/10 complexity

This Airworthiness Directive targets a specific safety hazard in Airparts FU24 aircraft (popular as agricultural topdressers and utility planes). If the cockpit rear bulkhead has a bracket for mounting a first aid kit, that bracket poses a head-strike risk to occupants.

What operators must do (choose one):

Option 1: Remove the bracket entirely; or
Option 2: Replace the first aid kit with a protective block made of energy-absorbing material

Why it matters: In turbulence or a hard landing, a rigid metal bracket behind the pilot's head is essentially a head injury waiting to happen. This rule eliminates that risk by either removing the hard point or cushioning it.

Compliance deadline: The work must be completed within 100 hours of flight time after 31 July 1973.
