Investigator assessment
Analysis narrative
The pilot reported that, during climb-out from a remote airstrip, he encountered an abrupt wind shift and windshear. According to the pilot, the airplane was unable to gain altitude and was eventually “forced” into the ground, causing substantial damage to the left wing, left horizontal stabilizer, and fuselage. The pilot reported that there were no pre-accident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
