NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

Witnesses reported that they observed the airplane make a normal takeoff. According to them, after starting to climb, the airplane entered a descent and crashed. They reported seeing the airplane in a right-wing low position before it impacted the ground in a nose down attitude. Examination of the airplane and the engine did not reveal any abnormalities. The pilot's last log book entry was dated 11/22/95. On 11/29/95, he had coronary artery bypass surgery. On 5/15/97, the FAA Aeromedical Certification Division denied the pilot a medical certificate 'due to objective evidence of myocardial ischemia by radionuclide scintigraphy.' An autopsy report of the pilot noted 'minimal cardiac tissue' for examination. Toxicology testing detected unspecified levels of metoprolol (a medication which reduces the heart rate response to stress) in the pilot's blood and liver fluid.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

failure of the pilot to maintain control of the airplane during the initial climb after takeoff. The pilot's physiological conditions was a possible factor.
