CESSNA 650
THE PILOT STATED THAT THE AIRPLANE STARTED TO WEATHERVANE WHILE TURNING OFF THE RUNWAY ONTO THE TAXIWAY. NOSEWHEEL STEERING WAS INITIATED WITH NEGATIVE RESULTS. FULL POWER WAS APPLIED ON THE THRUST REVERSERS; THE AIRPLANE DEPARTED THE TAXIWAY AND CAME TO A STOP IN THE GRASS. THE PILOT THEN TAXIED FORWARD, AND THE NOSEWHEEL COLLIDED WITH A CEMENT PAD COLLAPSING THE NOSE GEAR. EXAMINATION REVEALED THAT THE LEFT HAND MAIN GEAR ASSEMBLY TRAILING LINK CONNECTORS PW21 AND PW 23 ANTI-SKID TRANSDUCERS WERE CROSSED, AND RESPONDED OPPOSITE OF HOW THEY SHOULD HAVE OPERATED.
On December 1, 1993, about 1538 eastern standard time, a Cessna 650, N700RR, registered to Consolidated International Services Inc., operating as a 14 CFR Part 91 executive/corporate flight, collided with a cement pad while taxiing back to the taxiway in the grass, collapsing the nose gear. Visual meteorological conditions prevailed and an IFR flight plan was filed. The airplane sustained substantial damage. The pilot-in-command, second officer, and two passengers were not injured. The flight originated from Morristown, New Jersey, about 2 hours 15 minutes before the accident. The pilot-in-command stated that after landing the airplane started to weather vane while transitioning to a taxiway. Nosewheel steering was initiated with negative results. Full power was applied on the thrust reversers and the airplane departed the taxiway and came to a stop in the grass. FAA personnel on duty in the control tower asked the pilot if he would be able to taxi the airplane back on to the taxiway. The pilot-in-command evaluated the situation and started to taxi forward. The airplane rolled forward about 10 to 15 feet and the nose gear collapsed. The pilot-in-command exited the airplane, observed that the nosewheel had contacted a cement pad, turned 90 degrees to the left, and the gear had collapsed. Examination of the airplane by personnel from Cessna Product Engineering, and the Director of Maintenance, Consolidated International Services, Inc., revealed the left hand main gear assembly trailing link connectors PW21 and PW23, antiskid transducers were crossed, and responded opposite of how they should have operated. The accident was initially reported to the NTSB by the FAA as an incident. As additional information was received from repair personnel, the incident was reclassified as an accident on December 13, 1993.
THE PIC'S IMPROPER DECISION TO TAXI THE AIRPLANE OFF THE TAXIWAY. CONTRIBUTING TO THE ACCIDENT WAS THE IMPROPER WIRING OF THE ANTI-SKID SYSTEM.
