On July 20, 2024, a Hawker 90 andXP, registration N526FC, was involved in an accident near Telluride, Colorado. The aircraft was operating as a Part 91 positioning flight from Telluride Regional Airport (TEX) to Miami Executive Airport (TMB).
What happened
During the takeoff roll on runway 27, the pilot observed that the aircraft had not reached 75% of the planned takeoff speed by the midpoint of the runway. The pilot subsequently decided to abort the takeoff. Despite the use of brakes, air brakes, and thrust reversers, the aircraft failed to slow down. Upon application of maximum braking, the aircraft veered to the right, exited the runway, and traveled over the engineered material arresting system (EMAS). The aircraft came to a stop approximately 150 feet from the runway threshold, resting partially on the EMAS and partially on a grass field.
Following the excursion, the pilot attempted to shut down the two Honeywell TFE731-50R turbofan engines by closing the high-pressure and low-pressure fuel flow controls, but the engines continued to run. Airport personnel disconnected the aircraft batteries in an attempt to stop the engines, which was also unsuccessful. The engines finally ceased operation after the pilot utilized manual control of the fuel control unit. The crew, consisting of the pilot and copilot, exited the aircraft via the front left cabin door and were not injured.
Post-event inspection by the pilot revealed that the wing flaps were fully retracted rather than being extended to the calculated 15°.
The investigation
At the time of the accident, the airport was at an elevation of 9,069 feet, with an estimated density altitude of 11,081 feet. Weather conditions were VMC with an easterly wind. The investigation noted that the EMAS sustained damage during the event. The aircraft sustained substantial damage to the lower fuselage. No ADS-B data was available for the departure from runway 27.
