The National Transportation Safety Board’s preliminary report on the November 10 crash of a Mitsubishi MU-2B on approach to Runway 18L at Tulsa, Okla., quotes a witness as saying that the turboprop’s left propeller did not appear to be turning moments before the crash. The accident killed Perry Inhofe, the only person aboard the aircraft.
The Eurocopter X3 hybrid made its record-breaking speed run just 10 days before the opening of the Paris Air Show, so it was not surprising that the EADS company brought both the unique aircraft and its crew to the Le Bourget biennial event. On June 7, the X3 flew at 255 knots in level flight and 263 knots in a dive, besting the previous record set by the Sikorsky X2 in September 2010 (250 knots level and 260 knots in descent).
GE Aviation Systems is looking to rename its integrated vehicle health monitoring system now that it is ready to see it enter service. The product has a launch application on an undisclosed business jet and is also being evaluated by prospective airline clients. “This turns unscheduled events into scheduled events and could save roughly $8 billion for the industry,” said president and CEO Lynn Bolsinger.
Boeing has added Hamilton Sundstrand to its team of suppliers on the KC-46 aerial tanker, awarding it a contract to supply its environmental-control system, electric-power generation system, emergency ram-air turbine system, fans and engine bleed-air system, engine controls and accessories, bleed-air leak detection system and the engine/APU fire detection and overheat detection system.
According to an industry source, Piaggio will announce more improvements for the P.180 Avanti twin turboprop before year-end. While the source wouldn’t discuss more details, one of the most obvious areas that Piaggio has yet to address is the Avanti’s unmistakable whine, which has led to its being the only modern turboprop banned under noise restrictions at Santa Monica (Calif.) Airport.
Sabreliner NA-265-80, Fort Lauderdale, Fla., Feb. 1, 2008–Depletion of pressure in the aircraft’s hydraulic system, along with the pilot’s failure to operate the emergency braking system properly, was to blame for a taxiing accident that damaged three other airplanes, according to the NTSB. A non-functioning hydraulic system aural warning in the aircraft was also found to be a contributing factor.
Hawker Beechcraft C99, Kearney, Neb., Jan. 6, 2010–The turboprop twin, operating under Part 135, was substantially damaged during a hard landing in IMC at Kearney Municipal Airport. The pilot reported that he cycled the de-icing boots before the final approach fix after noting light to moderate icing.
Sabreliner NA-265-80, Fort Lauderdale, Fla., Feb. 1, 2008–While taxiing the Sabreliner from the repair station–following a months-long stay for corrosion repairs–the pilots attempted to maneuver around a Cessna Caravan that had stopped, facing it on the same ramp. As it passed, the Sabreliner’s left wing struck the Caravan’s rotating propeller, causing damage to both aircraft.
Before the long-delayed first flight of the A400M, the new airlifter’s TP400 turboprop was flown 18 times on a C-130 flight test bed (FTB) modified and flown by Marshall Aerospace. This was a challenging task, since the TP400 produces 2.5 times the thrust of a C-130’s standard T56 engine and weighs twice as much.
Before the long-delayed first flight of the A400M, the new airlifter’s TP400 turboprop was flown 18 times on a C-130 flight test bed (FTB) modified and flown by Marshall Aerospace. During a presentation to the UK’s Royal Aeronautical Society last October, Marshall’s chief test pilot Iain Young and flight test engineer Rob Boyle described the challenging task.
