Mysterious ‘deviation’ derailed Continental jet - The Denver Post
Nothing easy to figure out here…
The plane continued out of the gully, bouncing over Kewaunee Street, the DIA service road, where the main landing gear apparently was sheared off. The main landing gear and brakes “were found in good condition by visual examination,” NTSB said. “There were no signs of hydraulic leaking or flat spots on the tires. The flight deck controls and corresponding control surfaces were found to be in the takeoff configuration.”
NTSB added that a preliminary examination of the jet’s rudder system “revealed no abnormalities or malfunctions.”
The agency said inspection of the plane’s engines and information from the flight data recorder “has not indicated any evidence of pre-impact malfunctions with either engine.”
“The FDR data shows that number one engine power was reduced before that of the number two engine during the accident sequence, and examination of the engine indicates that this reduction is consistent with snow and earth ingestion as the airplane departed the runway,” NTSB said.
The plane’s No. 1 engine was severed from the left wing toward the end of the accident sequence and was found lying next to the wrecked jet. The No. 2 engine remained attached to the right wing.
“FDR data also shows that both engines were commanded into reverse thrust following rejection of the takeoff by the flight crew, which occurred after the aircraft had already left the runway,” NTSB added.

The area that is now DIA was the area where a lot of Microburst were found before the airport was built and after we learned about Microburst from the landing accidents in other states. I remember Citation Jet flying tests over the area for several months to determine how bad the Microburst were in the area. DIA has wind sheer measuring devices all over it to alert pilots of Microburst before they are in them. but no indicators show this was happening here.
