SUPERSEDED BY EASA AD 2023-0021
Summary
EASA Airworthiness Directive 2022-0008 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting GE Aviation Czech H75, H80, and H85 engine models installed on various aircraft including the Aircraft Industries L410-UVP-E20 and L410-NG, RUAG Aerospace Do 28 series, Thrush Aircraft 510G and S-2R series, and Viking Air DHC-3 Otter aeroplanes. The directive mandates compliance with updated airworthiness limitations published in the GEAC Engine Maintenance Manual to ensure continued safe operation of these engines.
What Changed
This directive introduces updated coefficients for calculating the cyclic and safe life of the main shaft and incorporates new or more restrictive maintenance tasks and life limits as specified in the latest Airworthiness Limitations Section of the GEAC Engine Maintenance Manual Revision 22. It requires operators to replace components before exceeding life limits and to perform maintenance tasks within specified thresholds and intervals.
Why It Matters
Compliance with EASA Airworthiness Directive 2022-0008 is critical for aviation professionals to maintain engine safety and airworthiness. Failure to adhere to the updated maintenance requirements could lead to unsafe conditions and potential engine failures. Operators, maintenance organizations, and compliance teams must ensure their maintenance programs reflect these changes to avoid regulatory non-compliance and ensure continued airworthiness.
What To Do
Affected operators must implement the updated maintenance tasks and life limits from the GEAC Engine Maintenance Manual starting from the effective date of 2022-02-02. They must revise their approved Aircraft Maintenance Programme within 12 months of the effective date to incorporate these changes. Any discrepancies found during maintenance must be corrected before the next flight, and if corrections are not covered by existing instructions, GEAC must be contacted for approved procedures.
