Accident occurred Saturday, September 07, 1996 in GLENNALLEN, AK
Probable Cause Approval Date: 04/15/1998
Aircraft: Champion 7GCBC, registration: N88359
Injuries: 2 Fatal.
NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
The airplane made a low pass over a track vehicle and some hunters. The hunters knew the pilot and passenger. The hunters observed the airplane make a nose-high turn and then crash to the ground. One of the hunters, a pilot, said that the airplane appeared to stall during the turn to reverse direction. Postaccident inspection of the airplane disclosed no evidence of any preimpact mechanical deficiency. Toxicological testing of the pilot's blood showed 0.010 mcg/ml chlorpheniramine (an over-the-counter antihistamine with sedative side effects) and unreported levels of pseudoephedring and phenylpropanolamine (over-the-counter decongestants).
The National Transportation Safety Board determines the probable cause(s) of this accident to be: failure of the pilot to maintain adequate airspeed, while maneuvering a low altitude, which resulted in an inadvertent stall and an uncontrolled collision with the terrain. A factor related to the accident was: the pilot's use of a medication with sedative side effects. Full narrative available
