What to do
Operators of affected helicopters must replace any installed affected rescue hoist assemblies with serviceable parts within specified compliance times—either within 24 months or 1,200 to 1,600 hoist cycles depending on the helicopter group, or within 30 days or 50 hoist cycles from the original AD effective date, whichever occurs later. Installation of affected parts is only allowed if they meet serviceable criteria, and subsequent replacement is mandatory. Compliance must follow the instructions in the applicable Alert Service Bulletins.
Summary
EASA Airworthiness Directive 2025-0051R1 is a regulatory update addressing the replacement of rescue hoist assemblies on various Airbus Helicopters and Leonardo helicopter models, including the H160-B, EC 225 LP, EC 175 B, AS 332 L2, AS 365 N3, EC135, MBB-BK117, AW109SP, AB139, AW139, AW169, and AW189. The directive mandates inspections and replacement of affected hoist assemblies due to potential non-conformant overload clutch assemblies that could lead to hoist failure. This AD applies to all serial numbers of the listed helicopter models and specifies affected part numbers and serviceable part criteria.
What changed
EASA Airworthiness Directive 2025-0051R1 revises the original AD 2025-0051 by correcting the rescue hoist assembly part number for the Leonardo AW109SP helicopter and clarifying that the term 'cycles' refers specifically to 'hoist cycles'. It also updates compliance instructions and timelines for replacement of affected parts.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk involving potential failure of rescue hoist assemblies, which could result in injury to personnel during hoist operations. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and operational safety. The AD provides clear guidance on identifying affected parts and timelines for replacement, helping compliance teams manage regulatory obligations effectively.
