What to do
Operators must replace components before exceeding new life limits and perform all maintenance tasks within specified intervals as detailed in the updated ALS. 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 according to SAFRAN-approved procedures before further flight.
Summary
EASA Airworthiness Directive 2026-0186 is an amendment addressing time limits and maintenance checks for SAFRAN Helicopter Engines RTM 322-01/9 and RTM 322-01/9A models, commonly installed on NH Industries NH90 military helicopters. This directive updates the Airworthiness Limitations Section (ALS) in the engine maintenance manuals to ensure continued airworthiness. It mandates compliance with new and/or more restrictive maintenance tasks and life limits.
What changed
This amendment supersedes the previous EASA AD 2024-0019 by introducing updated Airworthiness Limitations Sections (ALS) in the SAFRAN RTM 322-01/9 and RTM 322-01/9A engine maintenance manuals. The update includes new and more restrictive maintenance tasks and life limits that must be incorporated into the Aircraft Maintenance Programme (AMP). Operators must now comply with these revised requirements to maintain engine airworthiness.
Why it matters
For aviation professionals, this directive ensures that maintenance and life limits reflect the latest safety data, reducing the risk of engine failure due to overlooked or outdated procedures. Operators and maintenance organizations must update their maintenance programs to comply, which is critical for regulatory compliance and safe helicopter operations. Failure to comply could result in unsafe conditions and regulatory penalties.
