Aircraft involved
Probable cause & findings
THE UNFAVORABLE WIND CONDITION (PROBABLE WHIRLWIND OR SEVERE WIND SHEAR) THAT WAS ENCOUNTERED MOMENTS AFTER LIFT-OFF.
Factual narrative
THE PILOT HAD OBSERVED ADVERSE WEATHER CONDITIONS (WHIRLWINDS) IN THE AREA, BUT DUE TO THICK VEGETATION ON THE AIRPORT, HE WAS NOT AWARE THAT THESE CONDITIONS EXISTED FOR HIS TAKEOFF. HE STATED THAT HE ENCOUNTERED THIS ENVIRONMENT AT LOW AIRSPEED AT LIFTOFF. SUBSEQUENTLY, HE LOST CONTROL OF THE AIRCRAFT & THE LEFT WING TIP HIT THE GROUND, THEN THE ACFT CARTWHEELED & WAS DAMAGED.
