Introduction
On an unspecified date, a Machen modified Aerostar, registration N900CE, operated by pilot Glenn Cross, was involved in an accident while attempting to land at Marco Island Executive Airport.
Witness Observations
Multiple witnesses monitoring the aircraft's approach for runway 17 reported that the pilot appeared to have difficulty aligning the airplane with the runway centerline. The aircraft was described as unstable about the yaw and roll axes and appeared to be traveling too fast. Winds at the time were from the southwest at approximately 15 knots, gusting to 20 knots.
One witness, a pilot near the touchdown area, observed the right wheel make contact with the runway. The aircraft then climbed back to about 50 feet above ground level without the full addition of engine power. Most witnesses interpreted this as either a go-around or an extended touchdown further down the runway.
The airplane continued, becoming "more and more wobbly," until it entered a climbing attitude accompanied by a sharp left bank and turn. About halfway down the runway, the left wing dropped and contacted terrain to the left of the runway. The aircraft then slid into mangrove trees and was consumed by fire.
Postcrash Examination
Following the accident, examination of the wreckage confirmed flight control continuity from the control surfaces to the cockpit floorboards. No pre-impact condition was found with either engine or propeller that would have precluded proper operation.
A witness who listened to the pilot's initial radio call for approach and landing reported that the pilot communicated no abnormalities.
Toxicology
Postmortem toxicological testing was conducted on specimens from the pilot by the FAA Toxicology and Accident Research Laboratory and the Dade County Medical Examiner. The tests revealed the presence of quinine in the blood and urine. According to the source, side effects of quinine can include disturbances of vision, hearing, and balance.
