In a Service Bulletin issued May 3, winglet manufacturer Aviation Partners (API) instructed operators with winglet-equipped 800-series Hawkers modified by STC#ST01411SE to reduce maximum permissible altitude to 34,000 feet. “Several instances of aileron/wing oscillations have been reported on the Hawker 800 [series],” the company said. “Aviation Partners and the FAA consider this Service Bulletin to be a safety-related limitation until a design change to preclude the oscillations is developed and FAA approved.”
Loss of control in flight related to the inability to recognize an upset and controlled flight into terrain remain the primary causes of accidents involving transport aircraft.
The FAA has issued a notice of proposed rulemaking for an Airworthiness Directive for certain Embraer Phenom 300s. It is based on an unsafe condition as a result of an inadequate number of drain holes in the primary control surfaces (rudder, elevators and ailerons), which may allow water to accumulate in the control surfaces.
The FAA has issued an Airworthiness Directive for the Gulfstream Aerospace Galaxy and Gulfstream 200, citing cracked nuts found on the aircraft’s production line during routine post-assembly inspection. Investigation revealed that the cracks resulted from hydrogen embrittlement combined with high hardness.
There’s no better way to start off an EAA AirVenture show in Oshkosh, Wis., with a little flying out of the world’s busiest airport (during the week-long show, at least). Last year, the Gobosh folks were kind enough to invite me to fly the Gobosh 700A Light Sport Aircraft (LSA). This year, Remos Aircraft is demonstrating its newest LSA, the GX NXT, a high-wing composite two-seater powered by a 100-hp Rotax 912ULS.
The single-engine turboprop was destroyed but its ATP-certified pilot was unharmed when it departed the runway after touchdown at Montgomery County Airpark. The pilot told investigators that after he crossed the runway threshold at 81 knots and touched down normally, the TBM began to drift to the left. He attempted unsuccessfully to correct the drift by applying right rudder, and then began a
Commander 690, Wenatchee, Wash., Aug. 17, 2009–The twin turboprop suffered damage to its wing spar and ailerons after hitting trees during a family scenic mountain flight. According to a passenger, as the aircraft flew over a local ski area, friends of the family were spotted in the parking lot.
Bombardier Learjet 35A, Goodland, Kan., Oct. 17, 2007–The pilot’s failure to maintain control of the Learjet was the cause of its running off the runway on landing at Renner Field, according to the NTSB.
Bombardier Learjet 35A, Goodland, Kan., Oct. 17, 2007–The Jagee Ventures Learjet broke out of the clouds at 250 feet agl on approach to Runway 30 at Renner Field, slightly left of centerline. The pilot, in aligning the airplane with the centerline, experienced an uncontrolled left and right rolling motion.
Raytheon Aircraft’s failure to provide wing-structure data will delay by several months Aviation Partners’ blended winglet program for the Hawker 800, a program for which the Seattle-based modification designer had hoped to receive certification this summer.
