EASA AD 2018-0173-E
Equipment & Furnishings — Hoist Carrier Assembly — Inspection
Summary
EASA Airworthiness Directive 2018-0173-E is an emergency directive addressing inspection requirements for the Goodrich electrical hoist carrier assembly installed on Airbus Helicopters AS 332 L2, EC 225 LP, AS 365 N3, and EC175 B models. The directive mandates inspection of specific hoist part numbers to detect incorrect assembly that could lead to carrier assembly loosening and potential load loss. It applies to all serial numbers of the affected helicopter models and requires compliance with Airbus Helicopters Alert Service Bulletins.
What Changed
This new emergency airworthiness directive introduces a one-time inspection requirement for the hoist carrier assembly on affected helicopters due to a reported assembly defect. It also requires inspection before any (re)installation of the affected hoist parts and mandates replacement if incorrect assembly is found. The directive provides detailed part numbers and service bulletin references for compliance.
Why It Matters
This directive is critical for aviation professionals to prevent potential accidents caused by hoist carrier assembly failure, which could result in load loss and injury to people on the ground. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. The directive also clarifies inspection and replacement procedures, helping compliance teams manage regulatory obligations effectively.
What To Do
Operators of AS 332 L2, EC 225 LP, AS 365 N3, and EC175 B helicopters must inspect the hoist carrier assembly before the next hoist operation after 2018-08-10, following the applicable Airbus Helicopters Alert Service Bulletin instructions. If defects are found, the hoist carrier assembly must be replaced before further use. Additionally, any affected hoist part must pass inspection prior to installation or reinstallation on any helicopter.
