What to do
Operators of affected AW169 helicopters must inspect both fuel tank vent lines within 50 flight hours or 2 months from 16 November 2021, whichever occurs first. If any obstruction or discrepancy is found, the sealant must be removed before the next flight, and approved corrective actions from Leonardo must be followed within the specified compliance time. Contact Leonardo for guidance on corrective measures if needed.
Summary
EASA Airworthiness Directive 2021-0238 is an airworthiness directive issued for Leonardo S.p.A. AW169 helicopters, specifically serial numbers 69006 to 69125 inclusive (except 69040) and serial numbers 69130, 69132, 69133, 69134, 69136, and 69139. The directive mandates inspection of the fuel tank vent lines to ensure they are free from obstructions caused by excessive sealant. This inspection aims to prevent potential fuel starvation that could lead to dual engine flame out.
What changed
EASA Airworthiness Directive 2021-0238 introduces a new mandatory one-time inspection requirement for the fuel tank vent lines on specified AW169 helicopter serial numbers. It requires operators to inspect for sealant obstructions and perform corrective actions if discrepancies are found. This directive does not supersede any previous ADs.
Why it matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition that could cause dual engine flame out due to fuel starvation. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. Failure to comply could result in operational restrictions or safety risks during flight.
