## Analysis

THE AIRCRAFT WAS APPROXIMATELY 180 LBS OVER MAX RECOMMENDED TAKEOFF GROSS WEIGHT AND USED ALMOST ALL OF A 3560 FOOT RUNWAY TO TAKE OFF. THE PILOT STATED THAT AFTER LIFTOFF THE AIRCRAFT WOULD NOT TURN LEFT AND BEGAN TO TURN RIGHT ON ITS OWN. HE CLIMBED TO APPROX 150 FEET AND BEGAN TO SETTLE BACK TOWARD THE GROUND IN THIS CONTINUOUS RIGHT TURN. HE THEN STRUCK A UTILITY POLE THEN THE GROUND. AN ENGINE TEARDOWN REVEALED NOTHING THAT WOULD HAVE CAUSED AN INFLIGHT ENGINE PROBLEM. THE PILOT WAS FLYING ON AN EXPIRED MEDICAL CERTIFICATION AND DID NOT HAVE A BIENNIAL FLIGHT REVIEW WITHIN THE LAST 24 MONTHS. IN ADDITION, THE AIRCRAFT HAD NOT HAD AN ANNUAL INSPECTION SINCE 1981.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
