EASA AD 2023-0083
Time Limits / Maintenance Checks — Airworthiness Limitations Section — Amendment
Summary
EASA Airworthiness Directive 2023-0083 is an amendment addressing the time limits and maintenance checks for Airbus Helicopters EC 120 B models. It mandates compliance with the updated Airworthiness Limitations Section (ALS) Revision 003 to ensure continued airworthiness. This directive applies to all serial numbers of the EC 120 B helicopter.
What Changed
This amendment supersedes previous directives DGAC France AD F-2006-040 and EASA Emergency AD 2010-0026-E by incorporating new and more restrictive maintenance tasks and life limits introduced in ALS Revision 003. It updates the Aircraft Maintenance Programme (AMP) requirements to include these revised tasks and thresholds. Operators must now follow the latest ALS to maintain compliance.
Why It Matters
For aviation professionals, this directive ensures that maintenance and replacement of life-limited parts on the EC 120 B helicopters are performed according to the latest safety standards. It helps prevent unsafe conditions by enforcing stricter maintenance intervals and tasks. Compliance is essential for operators, maintenance organizations, and regulatory teams to maintain aircraft airworthiness and regulatory approval.
What To Do
Operators must replace components before exceeding life limits and perform all maintenance tasks within specified intervals as per ALS Revision 003 starting from 3 May 2023. They must revise the approved Aircraft Maintenance Programme within 12 months of the effective date to incorporate the updated limitations and tasks. Any discrepancies found during maintenance must be corrected before the next flight, following Airbus Helicopters' instructions or approved alternatives.
