Hydraulic fluid

September 10, 2012 - 2:10pm

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.

Business jet manufacturers are quietly progressing toward more-electric architectures, where electricity replaces hydraulic and pneumatic power in systems such as brakes, landing gear or even control-surface actuation. This avoids the use of environmentally unfriendly hydraulic fluids and ultimately should help reduce fuel burn.

Dassault Aviation could launch an all-electric Falcon business jet program in 2014 or 2015, said company engineers at a conference held by the ASTech Paris Region aerospace cluster at the Paris Air Show in June.

Thales is to provide quadruple-redundant computers for the Gulfstream G650’s fly-by-wire (FBW) flight controls. The new large-cabin, ultra-long-range business jet will be the first to feature Thales’ Quad-Dual architecture. While Thales will act as Gulfstream’s deputy, the aircraft manufacturer retains authority for FBW system integration.

Nobody likes to disconnect a push-pull primary fluid line and take a shower in jet fuel or hydraulic fluid, especially in a combat situation. To avoid this all-to-common scenario on the new multinational F-35 Joint Strike Fighter, Lockheed Martin chose Eaton’s new Ultra-Mate couplings for primary fluid conveyance applications.

Four reported incidents of in-flight loss of hydraulic fluid led to an emergency AD being issued Friday for the 139 in-service Premier Is. None of the incidents led to any mishaps, according to Raytheon Aircraft. The problem has been traced to the failure of a hydraulic tube assembly in the left engine. The directive requires a visual inspection of the affected part before further flight and thereafter at intervals of 50 hours.

Eaton (Hall 4 Stand F12) has been selected by Embraer to provide five packages for Embraer’s Phenom 100 very light jet. These include the hydraulic power generation package, design of the aircraft’s flap system and landing gear control hydraulic components. It will also supply miscellaneous cockpit controls including the throttle, landing gear and flap selectors.
