Probable cause

The pilot's inadequate compensation for the wind conditions, and his failure to maintain directional control. A factor relating to the accident 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

The pilot said that prior to takeoff, he estimated the wind to be from 260 degrees at 8 to 10 knots. He said that during the takeoff roll on runway 33, he was unable to maintain runway heading. The airplane went off the right side of the runway, cleared a drainage ditch, and impacted the opposite embankment. After the accident, the pilot said the wind was from 260 degrees at 20 knots (23 mph) with gusts to 25 knots (29 mph). According to a Cessna Aircraft Company spokesman, the airplane was flight tested in a 30 mph direct crosswind.

Factual narrative

On January 20, 1996, approximately 1100 mountain standard time, a Cessna 180, N6502A, was destroyed when it impacted terrain during takeoff at Buena Vista, Colorado. The private pilot was not injured. Visual meteorological conditions prevailed at the time, and no flight plan was filed for the personal flight being conducted under Title 14 CFR Part 91. The flight was originating at the time of the accident.

The following is based on the Pilot/Operator Aircraft Accident Report. Prior to takeoff from runway 33, the pilot estimated the wind to be from 260 degrees at 8 to 10 knots. Although the initial takeoff roll was normal, the pilot was unable to maintain runway heading. The airplane went off the right side of the runway, cleared a drainage ditch, and impacted the opposite embankment. The pilot said after the accident he estimated the wind to be from 260 degrees at 20 knots (23 mph) with gusts to 25 knots (29 mph).

According to a Cessna Aircraft Company spokesman, the Cessna 180 Owner's Manual does not report a maximum demonstrated crosswind component. However, the airplane was certificated under CAR 3 (Civil Aviation Regulations) on December 23, 1952, and, according to the Technical Inspection Report (TIR), the airplane was flight tested in a 30 mph direct crosswind (0.2 Vso).
