Max Trescott and Rob Mark examine the July 20, 2024 runway excursion of Hawker 900XP N526FC at Telluride Regional Airport. The crew planned a Runway 27 departure from an airport elevation of 9,069 feet, with density altitude above 11,200 feet and takeoff calculations using nearly all of the 7,111-foot runway. But the jet began its takeoff with the flaps retracted instead of set to the planned 15 degrees, while a gusty tailwind exceeded the airplane’s operating limitation. Here are Takeoff Videos One and Two.

The aircraft never became airborne. After the crew rejected the takeoff, it ran through the engineered material arresting system and stopped beyond the runway. Both pilots escaped without injury, though the airplane sustained substantial damage and its engines continued running after impact.

Max and Rob analyze the cockpit voice recorder summary, the absence of audible checklist use or takeoff briefing, the missed opportunities to verify flap position, and the hazards of operating with almost no performance margin. They also discuss fuel-loading decisions at mountain airports, the unusual arrival hold on Telluride’s RNAV approach, unofficial instrument procedures, discrepancies in the pilots’ NTSB forms, and the lesson: disciplined checklist use, crew communication, and attention to detail are essential when conditions leave no room for error.
