Aircraft Accident/Incident Report

Pittsfield, Pennsylvania 16340
Friday, October 5, 2001 14:40 EDT

NTSB Narrative Summary Released at Completion of Accident

The airplane was cruising at 11,000 feet when the air traffic controller noticed it was over 40 degrees off its assigned heading. The controller contacted the pilot, who said he would correct his heading. The controller then offered him a direct course to his destination, which the pilot accepted. The controller observed the airplane make another "hard left turn," and queried the pilot again, but received no reply. The airplane lost 4,000 feet during a 24-second period, after which, radar contact ceased. Witnesses on the ground saw the airplane descend out of the clouds in a vertical spiral, then saw the left wing depart. The engine was running in an overspeed condition. Toxicological testing of the pilot, a retired medical doctor, revealed the presence of a barbiturate, an antidepressant, an antihistamine sometimes prescribed as a sleep aid, and quinine.

NTSB Probable Cause Narrative

The pilot's loss of control in flight due to spatial disorientation, and his subsequent overstress of the airplane during a recovery attempt. A factor in the accident was the pilot's use of inappropriate medications.
