Probable cause
The pilot's inadequate compensation for wind conditions. Factors were windshear and gusty crosswinds.
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 last en route weather report received by the pilot indicated the winds were from 040 degrees at 10 knots gusting to 25 knots. The nearest weather station reported the winds from 080 degrees at 19 knots gusting to 25 knots. During approach and landing flare to runway 36 the airplane encountered windshear and gusting winds and the pilot initiated a go around. However the airplane contacted the runway, the left main landing gear collapsed and the airplane slid off the left side of the runway.
Factual narrative
On August 1, 1993, at approximately 1245 central daylight time, a Beech 35-33, N864R, sustained substantial damage near Guymon, Oklahoma, following a loss of control during a go around in gusty crosswinds. The private pilot and three passengers did not receive injuries. Visual meteorological conditions prevailed for the personal cross country flight.
The nearest weather reporting station at the time of the accident was reporting the winds from 080 degrees at 19 knots gusting to 25 knots. Witnesses at the site reported the winds variable and gusting in excess of 25 knots.
The Pilot/Operator Report revealed the following information. The flight departed Cheyenne, Wyoming, earlier that day. The pilot received enroute weather from flight watch. Approximately 10 miles northweast of Guymon, Oklahoma, the pilot obtained the local weather over the airport unicom frequency. Winds were reported from 040 degrees at 10 knots gusting to 25 knots. On final approach to runway 36, the airplane encountered moderate turbulence. During the landing flare, the airplane encountered windshear. As the pilot initiated a go around, the left main gear impacted the runway and collapsed. The airplane slid on the ground and came to rest off the left side of the runway.
