Narrative:A Cessna 560XL, registration N560AR, was destroyed when it impacted a commercial structure in Farmington, Connecticut.
All four on board have died.
According to preliminary data recovered from the airplanes flight data recorder (FDR), both thrust levers were set at 66°, and both engines remained at 91% N1 throughout the takeoff roll from runway 02, a 3665-ft-long runway.
Tire skid marks from the right main landing gear tire were found, beginning about 2360 ft from the approach end of the runway. Left main landing gear tire skid marks were noted beginning about 2480 ft from the approach end of the runway.
While at an airspeed of about 100 knots, the pilot attempted to raise the nose of the aircraft, but pitch of the airplane minimally changed to about +1°. The weight-on-wheels (WOW) indication remained in an on-ground state until beyond the departure end of the runway where the terrain began sloping downward. After departing the runway at an indicated airspeed of about 120 knots, the airplanes pitch rapidly increased to about +22°and the stick shaker activated. The aircraft lifted off briefly and impacted a powerline pole, which caused a small explosion near the right engine. The airplane then began to oscillate about its pitch and roll axis and the airplane subsequently impacted a building.
An investigation of the wreckage showed that the parking brake handle in the cockpit, and the respective valve that it controlled, were both found in the brake set position.
Probable Cause:
Probable Cause: The pilot-in-commands failure to release the parking brake before attempting to initiate the takeoff, which produced an unexpected retarding force and airplane-nose-down pitching moment that prevented the airplane from becoming airborne within the takeoff distance available and not before the end of the airport terrain. Contributing to the accident were the
airplanes lack of a warning that the parking brake was not fully released and the Federal Aviation Administrations process for certification of a derivative aircraft that did not identify the need for such an indication.
