MITSUBISHI MU-2B-35, CAROLINA, PUERTO RICO, APRIL 15, 2002–Experiencing a loss of control while orbiting, Mitsubishi N45BS crashed into an automobile service facility near Carolina, Puerto Rico, at 3:03 p.m. IMC prevailed and no flight plan was filed for the Part 91 positioning flight from Rohlsen Airport (TISX), St. Croix, Virgin Islands, to Marin Airport (TJSJ), San Juan, Puerto Rico.
Safe Flight Instrument last month announced it has gained approval for a low-airspeed awareness (LAA) display as part of the angle-of-attack (AOA) computer system used in the EFI-890R retrofit cockpit in a Challenger 601-3A. The retrofit avionics system, developed by Universal Avionics of Tucson, Ariz., presents LAA warnings alongside TAWS, TCAS, weather, navigation and other flight information on four 8- by 9-inch displays.
RAYTHEON KING AIR E90, RENO, NEV., MARCH 13, 2002–The NTSB determined the probable cause of the accident was the pilot’s inadequate approach airspeed for the existing adverse meteorological conditions, followed by his delayed action to avert stalling and subsequent loss of control of the airplane. Contributing factors were reduced visibility due to the inclement weather and icing conditions.
Socata TBM 700, Lancaster, Calif., Dec. 27, 2005–The new owner of TBM N198X was receiving instruction from a CFI/ATP-rated pilot when the airplane crashed on short final approach to Runway 6 at General William J. Fox Airfield (WJF) in VMC.
Ask most professional pilots about either the USAir accident in Pittsburgh or the United Airlines crash in Colorado Springs, when the Boeing 737s flipped upside down before impact, and the discussion often focuses on whether it was wake turbulence, a roll cloud or a rudder hard-over that caused the crashes.
Diamond’s second single-engine D-Jet made its first flight on September 14 in London, Ontario. This D-Jet incorporates aerodynamic improvements derived from flight testing of the first D-Jet and is also production-conforming. Three more D-Jets in the final configuration are under construction, and certification flight testing should begin shortly.
A proposed AD would mandate replacing the pitot probes on nearly 160 U.S.-registered Hawker 800XPs because of reports that they have frozen above FL290, causing erroneous airspeed indications. New probes and their installation would cost about $14,500 per airplane, according to the FAA. Replacement would be required at the next 24-month inspection after the compliance date of the directive. Comments on the proposal are due by November 28.
“Welcome to Lear Jet Country,” a marketing slogan that attached itself to the early-20-series Lear Jet, is likely to be remembered only by industry old-timers who recall the airplane’s ability to take off and climb to 41,000 feet without effort. It is a capability that disappeared with the advent of the Learjet 35/36.
According to the final report of the Irish Department of Transport Air Accidents Investigation Unit (AAIU) published earlier this year, a Beech King Air 90 (registration N712DB) rolled and dived during an August 2006 flight in Ireland because the owner/pilot lost control of the aircraft during a missed approach in instrument conditions. The pilot’s inexperience was deemed a factor.
Emergency AD 2003-08-52 was issued last month for the GE CT7-9B turboprop in response to 12 compressor-stall events in Saab 340Bs over a six-month period. The stalls occurred when pilots throttled back from takeoff power to climb power. Nine of the events involved engines that had the compressor variable geometry (VG) rigged to N1, one of two allowable rigging options that affords slightly higher performance at the expense of stall margin.
