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.
Aviation Partners now expects to receive certification of its winglets for the Hawker 800 next May, nearly a year later than originally planned. Failure to obtain certain engineering data from Raytheon Aircraft caused the delay, according to Aviation Partners. The Seattle company claims winglets allow the “Hawker 800SP” to fly 30 min longer or 180 nm further and 18 kt faster than a standard Hawker 800.
Cessna is adopting “hybrid” fly-by-wire technology to actuate the flight controls on the Citation Columbus, formerly known as the Large Cabin Concept jet. This is Cessna’s first use of fly-by-wire flight controls in a Citation design, and the system combines electronic and mechanical control of flight control actuators.
Water that pooled under the floor panels of a Falcon 20, froze and restricted the movement of the aileron trim actuator as the airplane was landing at London Stansted Airport is to blame for the airplane’s “frozen” controls, according to the UK Air Accidents Investigation Branch.
CESSNA 650, RAPID CITY, S.D., AUG. 29, 2003–At approximately 4:30 p.m. Cessna N651EJ experienced a right-wing aileron cable failure while cruising at FL390. The flight originated in Marion, Ill., destined for Rapid City (RAP) and was approximately 200 miles southeast of RAP when the incident occurred. The ATP-rated pilot-in-command, the commercial-rated copilot and seven passengers were not injured.
Bombardier Learjet 35A, Nashville, Tenn., Dec. 26, 2006–The pilot’s inadequate compensation for a gusty crosswind, which resulted in loss of control and a wing strike on the runway, was responsible for the landing accident involving a Secure Air Charter Learjet, according to the NTSB.
When the Citation Sovereign receives certification, expected before year-end, it will include modifications that reduce lateral control forces. According to Cessna, initial flight tests showed lateral forces at high speeds of 40 to 50 pounds for roll rates of less than 10 degrees per second.
