An NTSB preliminary report posted yesterday provides details on a May 4 incident involving a Hawker 800A that went of control and lost more than 10,000 feet before recovering. N71MT, owned and operated by Raytheon Aircraft, was on a maintenance test flight and the crew was setting up for a stall series at 17,000 feet near Lincoln, Neb.
An excerpt from the NTSB’s update on its investigation into the crash of the Cirrus SR20 that hit the 30th floor of an apartment building on October 11 while trying to make a U-turn over the East River (New York) provides insight into the role of the wind. “Radar data indicate that the airplane was flying over the east side of Roosevelt Island prior to initiating a 180-degree turn.
Safe Flight is celebrating its 60th year of producing products to make aviation safer. In 1944, Leonard Greene saw an airplane flown by a friend appear to simply fall out of the sky, killing the pilot and destroying the airplane. Greene, an engineer, started Safe Flight Instrument Corp. in 1946 to develop lift instrumentation that would warn a pilot of an approaching stall. Safe Flight (Booth No.
Aviation Technology Group has added Goodrich Aircraft Interior Products, Kavlico, Moritz and Parker Aerospace to its list of suppliers for its Williams FJ33-powered Javelin business jet and derivatives. Under the terms of the contracts, Goodrich will supply pilot seats, Kavilco the throttle quadrant, Moritz the power distribution system and Parker the hydraulics.
A sage old pilot once neatly captured the purpose of business aviation: “People buy airplanes because they want to go places…fast.”
Spectrum Aeronautical (Booth No. 2142) continues to develop its Model 33 VLJ following the fatal crash of its sole prototype on July 25. In recent weeks the company has buttressed its engineering staff with new hires and is proceeding with the design and building of a conformal test article that will fly “in about a year,” according to Austin Blue, Spectrum’s president.
Quest Aircraft’s Kodiak turboprop single, which last month neared 100 flight hours, started FAA flight testing in late March. The Sandpoint, Idaho-based company also said the 10-seat airplane has successfully flown at all corners of its c.g. envelope and the projected stall speeds have been validated.
In its determination of probable cause, the NTSB implicated a history of stability issues at high Mach speeds in the April 26, 2003, crash of Sino Swearingen’s number-one SJ30-2 prototype. Company test pilot Carroll Beeler was killed in the accident.
A new pitch actuator will be required in some 330 U.S.-registered Pilatus PC-12s if the FAA adopts a proposed AD. The directive will require certain flap and autopilot limitations until the new actuator is installed. Pilatus reports the new actuator, which removes the flap-in-motion signal to the autopilot, is designed to prevent an abrupt nose-down pitch when the autopilot is disengaged while the flaps are at a 40-degree setting.
Challenger 600, Tupelo, Miss., March 9, 2005–Inadequate design of the STCed microphone jack assembly, resulting in restricted aft movement of the control column, was blamed for the accident of Romeo Mike Aviation’s Challenger.
