Incident Overview
A noninstrument-rated pilot, encountering en route weather, decided to divert and land at an en route airport. During the descent to that airport, the pilot reported a loss of engine power.
Witness and Passenger Observations
The passenger stated that the airplane "appeared to be gliding down toward a field and then it started to spin out of control." A witness observed the airplane at an altitude of 150 to 200 feet above ground level with the left wing low, then perpendicular to the sky, followed by a nose-low impact. The impact occurred short of the runway in flat terrain.
Aircraft and Systems Examination
Maintenance records did not reveal any uncorrected maintenance defects. Flight control continuity was confirmed. An engine test run to full throttle did not reveal any discrepancies that would have contributed to a total loss of engine power.
Interior Findings
The right rear forward-facing seat was found detached from the cabin floor, where the nut plates had pulled through the floor.
Toxicology and Medication
Prescription and nonprescription drugs were found in the aircraft. Toxicology tests were positive for Verapamil, a high blood pressure medication that may be approved by the Federal Aviation Administration for use by pilots; however, FAA records did not indicate that the pilot had requested approval to use the drug.
