Plain English Summary

2/10 complexity

Owners and operators of Airparts (NZ) FU24 series aeroplanes must comply with a mandatory CASA Airworthiness Directive requiring a detailed inspection of the forward base of the vertical fin to check for cracking around the fin-to-bulkhead rivet area. Access coverings and fairing must be removed to expose the area.

Any crack found grounds the aircraft until repaired. The inspection must be completed by 8 May 2002 to address a potential tail-structure failure risk.
