Any discrepancies found during maintenance must be corrected before the next flight, following manufacturer instructions or approved alternative methods.
Summary
EASA Airworthiness Directive 2024-0177 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting all Airbus Helicopters EC 175 B models. It mandates compliance with the updated Airworthiness Limitations Section (ALS) Revision 024 to ensure continued airworthiness of these helicopters. The directive consolidates and supersedes previous ADs related to maintenance tasks and life limits for critical components.
What changed
This directive supersedes EASA AD 2021-0038 and Emergency AD 2023-0182-E, incorporating new and more restrictive maintenance tasks and life limitations as defined in the latest AH EC 175 ALS Revision 024. It updates the maintenance program requirements to include these revised limitations and tasks, reflecting the latest safety information and manufacturer instructions.
Why it matters
Compliance with EASA Airworthiness Directive 2024-0177 is essential for operators and maintenance organizations to prevent unsafe conditions caused by exceeding component life limits or missing critical maintenance tasks. It ensures that helicopters remain airworthy by mandating adherence to the latest approved maintenance schedules and corrective actions. This directive also streamlines compliance by allowing incorporation of the updated ALS into the approved Aircraft Maintenance Programme.
