What to do
Operators of DA 42, DA 42 M, DA 42 NG, and DA 42 M-NG aeroplanes must replace components before exceeding their life limits and perform all maintenance tasks within specified intervals as per the updated ALS. They must revise their approved Aircraft Maintenance Programme within 12 months after the effective date of 7 October 2026 to incorporate these new requirements. Any discrepancies found during maintenance must be corrected before the next flight or as specified in the maintenance documentation.
Summary
EASA Airworthiness Directive 2026-0183 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Diamond Aircraft Industries GmbH DA 42, DA 42 M, DA 42 NG, and DA 42 M-NG aeroplanes of all serial numbers. This directive mandates compliance with updated airworthiness limitations and maintenance checks as specified in the Airworthiness Limitations Section (ALS) of the aircraft maintenance manuals and associated documents. It ensures continued airworthiness by enforcing life limits and maintenance tasks for critical components.
What changed
EASA Airworthiness Directive 2026-0183 introduces updated and more restrictive maintenance tasks and life limits, including a new life limit for the gas spring of the passenger door latching mechanism. It requires operators to comply with the latest revision 6 of the ALS documents and the associated mandatory service bulletin and temporary revision of the maintenance manual. This AD does not supersede any previous directives but adds new mandatory maintenance requirements.
Why it matters
This directive is critical for aviation professionals as it ensures the continued safe operation of affected Diamond DA 42 series aircraft by enforcing compliance with updated maintenance and life limit requirements. Operators, maintenance organizations, and compliance teams must integrate these changes into their maintenance programs to avoid unsafe conditions and regulatory non-compliance. Failure to comply could lead to unsafe aircraft conditions and regulatory penalties.
