EASA AD 2024-0050
Doors — Cargo Doors Closing Mechanism — Inspection
Summary
EASA Airworthiness Directive 2024-0050 is an airworthiness directive addressing the inspection of cargo doors closing mechanisms on Airbus Helicopters EC 175 B models. It focuses on specific left-hand and right-hand cargo doors with certain part numbers related to the closing mechanism attachment. The directive mandates repetitive inspections to detect corrosion and fatigue in the door closing springs to prevent potential in-flight door opening.
What Changed
This new airworthiness directive introduces mandatory repetitive inspections of the closing mechanisms on affected cargo doors of EC 175 B helicopters. It requires replacement of any affected parts found with discrepancies and allows an alternative method of locking the door with a key before flight. The directive does not supersede any previous AD but complements existing safety requirements.
Why It Matters
This directive is critical for operators and maintenance organizations to prevent in-flight cargo door openings that could lead to loss of the door or baggage and possible damage to the helicopter's tail components. Compliance ensures continued airworthiness and safety of EC 175 B helicopters by addressing corrosion and fatigue issues in modified door closing mechanisms. It also helps avoid potential accidents caused by door failures during flight.
What To Do
Operators must inspect the closing mechanism of each affected cargo door within 110 flight hours or 6 months after 7 March 2024, whichever occurs first, and repeat inspections at the same intervals. If discrepancies are found, the affected parts must be replaced before the next flight or the door locked with a key as an alternative. Only serviceable parts may be installed on helicopters from the effective date onward.
