Probable cause
Poor in flight planning/decision by the pilot in command. Factors to the accident were: down drafts, proper alignment was not maintained and inadequate remedial action.
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
Just after take off, the airplane encountered a down draft. The pilot lowered the nose of the airplane to increase airspeed and made a right turn passing over buildings, hangars, and the parking ramp. The airplane completed a 360 degree turn and the right wing contacted the ramp. The pilot was able to continue to fly the airplane and returned for landing without further incident.
