What to do
Operators must remove engine components before exceeding their life limits and perform all applicable maintenance tasks within specified thresholds and intervals starting from 2 January 2023. Any discrepancies found during inspections must be corrected within the specified compliance times or before the next flight. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months of the effective date to incorporate the updated limitations and tasks.
Summary
EASA Airworthiness Directive 2022-0255 is an airworthiness directive affecting SAFRAN Helicopter Engines RTM 322-01/9 engines, commonly installed on NH Industries NH90 military helicopters. It mandates compliance with updated airworthiness limitations and maintenance tasks as specified in the SAFRAN RTM 322-01/9 Engine Base Maintenance Manual Airworthiness Limitations Section approved on 30 October 2022. This directive ensures continued airworthiness by enforcing mandatory inspections and life limits for engine components.
What changed
This directive supersedes EASA AD 2022-0117 and introduces new and more restrictive maintenance tasks and life limits, including mandatory inspections for engines equipped with a new combustion chamber part number. It updates the Airworthiness Limitations Section to reflect these changes and requires operators to revise their Aircraft Maintenance Programme accordingly.
Why it matters
Compliance with EASA Airworthiness Directive 2022-0255 is critical for aviation professionals to maintain the safety and airworthiness of RTM 322-01/9 engines. Operators and maintenance organizations must implement the updated maintenance tasks and life limits to avoid unsafe conditions and ensure regulatory compliance. Failure to comply could result in unsafe engine operation and regulatory penalties.
