EASA AD 2022-0067
Time Limits / Maintenance Checks — Airworthiness Limitations Section — Amendment
Summary
EASA Airworthiness Directive 2022-0067 is an amendment addressing time limits and maintenance checks in the Airworthiness Limitations Section for Airbus Helicopters Deutschland GmbH EC135 and EC635 helicopter models. It mandates compliance with updated maintenance tasks and life limits as specified in the latest Airworthiness Limitations Section documents. This directive applies to all variants and serial numbers of the EC135 and EC635 helicopters.
What Changed
This directive supersedes previous ADs 2017-0243, 2018-0168R1, and 2018-0284, consolidating and updating maintenance requirements. It introduces new and more restrictive maintenance tasks and life limits, including repetitive inspections of main rotor actuators and replacement thresholds for components. The updated Airworthiness Limitations Section now governs the continuing airworthiness requirements.
Why It Matters
Compliance with EASA AD 2022-0067 is critical to ensure the continued safe operation of EC135 and EC635 helicopters by preventing unsafe conditions caused by overlooked maintenance or expired life limits. Operators, maintenance organizations, and compliance teams must update their maintenance programs to reflect these changes to avoid regulatory violations and potential safety risks. The directive ensures harmonized and mandatory maintenance standards across affected fleets.
What To Do
Operators must replace components before exceeding life limits and perform all maintenance tasks within specified intervals as per the updated Airworthiness Limitations Section starting from 27 April 2022. Any discrepancies found during inspections require corrective actions within specified times or before next flight if no time is given. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months after the effective date to incorporate all new tasks and limitations.
