Probable cause

The pilot's inadequate commpensation for 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.

Loss of control - on ground/waterLanding - roll
Weather condition - crosswind
Compensation for wind conditions - inadequatePilot in commandCause
Main gear collapsedLanding - roll

Analysis

The pilot reported that he was landing in a right crosswind. He lost directional control and allowed the left wing to contract the ground. His written statement says, in part: 'during the rollout phase of the landing I was leaving the shltered portion of the runway and was subjected to a 10 knot crosswind at a cirtical phase of the landing'.
