EASA AD 2024-0240
Aeroplane Flight Manual — Section Normal Procedures / Flight Director Lateral Offset — Amendment
Summary
EASA Airworthiness Directive 2024-0240 is an amendment concerning the Aeroplane Flight Manual Section Normal Procedures / Flight Director Lateral Offset for Pilatus PC-24 aeroplanes. It addresses an issue with inaccurate flight director calculations on approach caused by certain software versions. This directive applies to all PC-24 aircraft serial numbers and mandates updates to the flight manual procedures.
What Changed
This directive requires the implementation of Pilatus PC-24 Aeroplane Flight Manual Temporary Revision 02371-075 to introduce an abnormal procedure that mitigates errors in flight director lateral offset calculations. The amendment specifically targets aircraft with APEX Build 5.3 and below software versions. It is an interim action pending further regulatory updates.
Why It Matters
The inaccurate flight director calculations can increase pilot workload and reduce safety margins during approach, which is critical for safe flight operations. Compliance ensures that pilots are informed of the abnormal procedure to manage lateral offset errors effectively. Operators and maintenance teams must update manuals and train crews to maintain regulatory compliance and flight safety.
What To Do
Operators must implement the Aeroplane Flight Manual Temporary Revision 02371-075 within 30 days of the directive's effective date, inform all flight crews, and operate the aircraft accordingly. Incorporating this temporary revision or a later approved AFM revision satisfies the directive's requirements. Alternative methods of compliance may be approved by EASA upon request.
