The FAA issued an ADDocket FAA-2012-0222– on September 6 for some versions of the Eurocopter AS350. The directive, which is effective from October 11 this year, was issued after an in-flight fire caused by the ignition of hydraulic fluid leaking from a damaged forward servo-control hydraulic hose. The AD is intended to prevent the forward servo-control hydraulic hoses from becoming damaged and leaking hydraulic fluid that could ignite in flight.

The FAA is adopting an Airworthiness Directive (AD 2012-08-11) for certain Bombardier Dash 8-400 turboprop aircraft, to alleviate potential landing gear issues. The problems were identified during testing, which showed that failure of a retract-port, flexible hose on the main-landing-gear actuator could result in excessive leakage of hydraulic fluid.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Eurocopter AS350 helicopters. Prompted by an in-flight fire caused by ignition of hydraulic fluid leaking from a damaged forward (pitch) servo-control hydraulic hose, the proposed AD is intended to prevent the forward servo-control hydraulic hoses from becoming damaged and leaking hydraulic fluid that could ignite in flight, which can result in loss of main rotor control, power loss, structural damage, propagation of fire and subsequent loss of control of the helicopter.
