Probable cause
The excessive taxi speed used by the pilot exiting the runway via a high-speed taxiway resulting in a loss of control. A factor was the crosswind.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During landing roll, the aircraft exited the runway via a high-speed taxiway and despite heavy breaking by the pilot the aircraft nosed over. Wind at the time was a direct cross wind recorded at 10 knots.
Factual narrative
On October 14, 1999, at 1015 mountain daylight time, a Cessna 180D, N6425X, sustained substantial damage when it nosed over during landing roll at Denver International Airport, Denver, Colorado. The private pilot and his pilot certificated passenger were not injured. The flight was operating under Title 14 CFR Part 91 and no flight plan was filed. This personal flight departed Boulder, Colorado, at 0945. Visual meteorological conditions prevailed.
According to the pilot, he was exiting the runway (17R) with a right turn onto a high-speed taxiway when the tail and right wing began to rise. The application of heavy breaks had no effect and the aircraft nosed over.
At the time of the accident, Denver International Airport recorded wind was from 270 degrees magnetic at 10 knots. There were no gusts recorded.
The pilot provided information that he did not believe there was any aircraft malfunction or failure. This was verified by an FAA inspector who examined the aircraft.
