Bombardier Learjet 35, Ciudad Victoria, Mexico, Feb. 5, 2009–The jet lost control upon landing at Ciudad Victoria Airport. After touchdown, the aircraft slid off the runway onto the grass and came to rest upright after a 180-degree left turn. The landing gear collapsed, resulting in damage to the landing gear structural supports. Neither of the two crew-members was injured. Mexico’s civil aviation authorities are investigating the accident.
Rockwell 690C, Minden, Nev., May 2, 2008–The board was unable to determine why both main landing gear collapsed, substantially damaging the Twin Commander while it taxied for takeoff at Minden-Tahoe Airport. An FAA inspector said the landing gear’s clamshell doors remained in the closed position, inconsistent with its being in an in-transit operating mode. The gear select handle was found in the “down” position.
The FAA returned the repair station certificate that it suspended from AAR Landing Gear Services on February 10, and the AAR division immediately resumed working on customer landing gears. While the FAA claimed that AAR “returned aircraft parts to service as being overhauled when they were not, and failed to perform required maintenance procedures,” the company filed a petition for review with the NTSB.
Bombardier CL600-2B19 CRJ, Philadelphia, Dec. 14, 2008–The Air Wisconsin CRJ landed at Philadelphia International Airport with the left main landing gear retracted. En route, the crew had noted problems with the left gear and could not get it to lower. They landed with the nosegear and the right gear down and locked. Maintenance had been performed on the landing-gear systems before the flight.
A preliminary report issued by the NTSB yesterday on the facts surrounding the December 20 accident of a Continental Airlines Boeing 737-500 at Denver International Airport noted that after the captain unsuccessfully tried to correct the airplane’s deviation from the runway centerline on takeoff with the rudder, he tried briefly to use the tiller to manipulate the steering of the nosegear.
Bombardier DHC-8-311 Dash 8, Philadelphia, Nov. 16, 2008–The nosegear of the Piedmont Dash 8 failed to extend on approach to Philadelphia International Airport and the crew made a go-around to try to get it down. Unable to correct the problem by performing the alternate landing gear extension procedure, the crew landed on the main gear and attempted to delay the nose from touching down until the slowest speed possible.
Construcciones Aeronauticas SA CASA 212-200, Toksook Bay, Alaska, Nov. 1, 2008–The Arctic Transportation Services CASA 212 made a forced landing on the tundra when the captain was unable to maintain altitude after the right engine experienced a problem. The airplane was on a VFR approach to Toksook Bay, when the copilot added power. The right engine failed to respond, and the aircraft yawed right.
The UK Air Accidents Investigation Branch (AAIB) has issued four safety recommendations in response to an incident in which a burst tire on a Bombardier Global Express caused “extensive damage” to the flight control system.
Cessna 750 Citation X, New York, N.Y., April 3, 2008–The Citation X ran off the runway on landing at John F. Kennedy International Airport because of the copilot’s failure to maintain directional control during the landing roll. A contributing factor was a loss of system A hydraulic fluid for undetermined reasons and the flight crew’s failure to follow the checklist sequence.
Hawker Beechcraft King Air C90, Baton Rouge, La., April 25, 2008–Structural failure of the right main landing gear torque knee caused the King Air’s gear to collapse on landing at Baton Rouge Metropolitan Airport, the NTSB determined. Failure to inspect the torque knee at the designated 1,000-hour interval, as required by AD 2002-01-10, was a contributing factor.
