Probable cause
Pilot's inadequate compensation for the wind conditions.
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 private pilot encountered a whirlwind while on final to his ranch airstrip. He said the turbulence was severe and the plane landed hard, damaging the landing gear, the propeller, and tearing the left wing loose at the root. The pilot originally reported 'minor' damage, but later reported 'substantial' damage to the FAA.
