Plain English Summary

4/10 complexity

This mandatory Airworthiness Directive covers all Fokker F27 aircraft in Australia, requiring inspection, repair or retirement of airframe and landing-gear components to the specific Fokker and Dowty Rotol documents, and permanent removal from service before 90,000 flights.

Operators cannot use flight-data or fatigue-meter allowances to extend that limit, and aircraft with known unrepaired cracks may not fly without CASA or an authorised structural engineer’s approval. Amendment 7 removes permissive wording so only the exact listed document revisions apply.
