EASA AD 2023-0143
Time Limits / Maintenance Checks — Airworthiness Limitations Section — Amendment
Summary
EASA Airworthiness Directive 2023-0143 is an amendment concerning the Airbus Helicopters AS 332 L model. It mandates compliance with the updated Airworthiness Limitations Section (ALS) for time limits and maintenance checks to ensure continued airworthiness. This directive replaces previous maintenance instructions with a more current and segregated ALS document.
What Changed
EASA Airworthiness Directive 2023-0143 introduces the requirement to follow the Airbus Helicopters AS 332 L ALS Revision 009 dated 2022-07-27, replacing the earlier maintenance instructions from the Master Servicing Manual. It cancels the previous AD 2010-0234 and requires operators to incorporate new or more restrictive maintenance tasks and life limits into their Aircraft Maintenance Programme.
Why It Matters
This directive is critical for operators and maintenance organizations to maintain the safety and airworthiness of AS 332 L helicopters by ensuring compliance with the latest mandatory maintenance tasks and life limits. Failure to comply could lead to unsafe conditions and regulatory non-compliance. It streamlines maintenance requirements by consolidating airworthiness limitations into a dedicated ALS document.
What To Do
Operators must replace components before exceeding service life limits and perform all maintenance tasks within specified intervals as per the ALS starting from 28 July 2023. Any discrepancies found during maintenance must be corrected within the ALS compliance times or before the next flight if no time is specified. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months after the effective date to incorporate the updated ALS tasks and limitations.
