What happened
During an approach to runway 17 at Marco Island Executive Airport, witnesses observed the Machen modified Aerostar, registration N900CE, struggling to maintain the runway centerline. Observers noted that the aircraft exhibited instability in both roll and yaw, appearing to travel at an excessive speed. Environmental conditions at the time included southwest winds of approximately 15 knots, with gusts reaching 20 knots.
As the aircraft neared the touchdown zone, the right wheel made contact with the ground before the plane climbed back to an altitude of roughly 50 feet above ground level without a significant increase in engine power. While some observers believed the pilot was initiating a go-around, the aircraft continued down the runway with increasing instability. The aircraft eventually entered a climbing attitude accompanied by a sharp left bank. Approximately halfway down the runway, the left wing struck the terrain, causing the aircraft to slide into nearby mangrove trees, where a fire broke out. The accident resulted in one fatality.
Findings
Investigations into the wreckage confirmed that flight control continuity remained intact from the control surfaces to the cockpit floorboards. There were no mechanical issues identified in the engines or propellers that would have prevented normal operation prior to the crash. Additionally, the pilot had reported no abnormalities during the initial radio communications for the approach.
Toxicology results from the pilot's blood and urine samples showed the presence of quinine. This substance is known to cause side effects such as impaired vision, hearing, and balance, which may have contributed to the instability of the aircraft during the approach.
