The accident killed Perry Inhofe, the only person aboard the aircraft.

The Eurocopter X3 technology demonstrator flew at 255 knots in level flight, an unofficial record for a helicopter, on June 7. It also reached 263 knots in a dive. “It’s no exaggeration to say that the X3 is clearly in its element at high speeds,” said Hervé Jammayrac, Eurocopter test pilot.

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).

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.

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.
