EASA AD 2023-0182-E
SUPERSEDED BY EASA AD 2024-0177
Summary
EASA Airworthiness Directive 2023-0182-E is an emergency directive addressing Airbus Helicopters EC 175 B models equipped with specific Emergency Rescue Hoist systems (MP/N 42325-16-6 or MP/N 42325-19-106). It mandates updated maintenance requirements including overhaul and functional checks of the rescue hoist to ensure continued airworthiness. The directive applies to all serial numbers of the EC 175 B helicopter type certificate EASA.R.150 S.
What Changed
This directive introduces revised calendar times for overhaul and functional checks of the affected rescue hoist parts, defining these intervals based on time since manufacture or last overhaul rather than previous criteria. It also adds a new functional check for the slip-clutch torque limiter related to oil condition. These changes correct previous timing errors and add safety measures not covered in earlier directives.
Why It Matters
For operators and maintenance organizations, compliance with EASA AD 2023-0182-E is critical to prevent unsafe conditions related to the rescue hoist system. The updated maintenance intervals and functional checks help ensure the reliability and safety of the hoist, which is vital for rescue operations. Failure to comply could lead to operational restrictions or safety risks during hoist missions.
What To Do
Operators of EC 175 B helicopters with affected rescue hoist parts must replace these parts within specified intervals not exceeding 40 months or 2,000 hoist cycles, whichever occurs first, and perform functional load checks every 6 months or 300 hoist cycles. If discrepancies are found during checks, corrective actions must be taken before next flight. Alternatively, operators may deactivate the hoist or remove the affected part to avoid overhaul requirements. Compliance deadlines depend on the time since manufacture or last overhaul as detailed in the directive.
