AD NUMBER: 2012-17-03
PRODUCT: Certain Eurocopter France Model AS350 helicopters.
SUBJECT: Airworthiness Directive 2012-17-03
ACTION: Final Rule
SUMMARY: This AD requires installing protection sleeves over certain forward (pitch) servo-control hydraulic hoses. This AD was prompted by an in-flight fire caused by the ignition of hydraulic fluid leaking from a damaged forward servo-control hydraulic hose.
This AD's actions are intended to prevent the forward servo-control hydraulic hoses from becoming damaged and leaking hydraulic fluid that could ignite in flight, which could result in loss of main rotor (M/R) control, power loss, structural damage, propagation of fire, and subsequent loss of control of the helicopter.
DATES: This AD is effective October 11, 2012.
