Probable cause

The pilot's failure to follow procedures pertaining to mountain flying, and the pilot's failure to maintain airspeed that resulted in an inadvertent stall and subsequent in-flight collision with trees and terrain. A factor was the certified flight instructor inadequate supervision of the training flight.

Analysis

The pilot was conducting a mountain flying instructional flight with a certified flight instructor practicing steep turns and emergency course reversal in a canyon after attending a mountain flying course in the morning. The airplane was observed by two witnesses flying at a very low altitude above the trees. The airplane made about five steep left turns, at about a 45-degree angle of bank. The airplane flew back over the witnesses's location and back into the valley. The airplane was observed to start another steep turn to the left and disappeared from view behind the trees. Witnesses heard an increase in engine power followed by the sound of an airplane colliding with trees. Examination of the airplane, flight controls, and engine assembly revealed no anomalies.

Factual narrative

History of flight

On August 10, 2002, about 1620 eastern daylight time, a Cessna 182R, N9307X, registered to the Civil Air Patrol (CAP), operating as a 14 CFR Part 91 training flight, crashed on Cross Mountain, located about 2 ½ miles north west of Lake City, Tennessee. Visual meteorological conditions prevailed and an internal CAP flight plan and a computer weather briefing were obtained. The airplane was destroyed. The airline transport pilot-in-command, airline transport rated certified flight instructor (CFI), and commercial rated pilot passenger were fatally injured. The flight originated from Jacksboro Campbell County Airport, Jacksboro, Tennessee, at an undetermined time. Civil Air Patrol ground search team located the wreckage on August 11, 2002.

The Group Commander for the Group 1 Civil Air Patrol located at Knoxville Downtown Island Airport, Knoxville, Tennessee stated the three pilots attended a mountain flying clinic on the morning of the accident. The pilots were then scheduled to conduct mountain training with a CAP instructor pilot/check pilot. The three pilots departed Knoxville between 1315 to 1330. The Group Commander overheard the CFI tell the other pilots receiving instruction that the commercial pilot passenger would be the first pilot to fly and they would land and switch seats at another airport. The pilots were expected to return at about 1600 according to the CAP Form 104 Mission Flight Plan/Briefing Form completed for the training flight. The crew indicated on CAP Form 104 that they would be flying in Search Area A conducting mountain flying, which includes Lake City, Tennessee, and Cross Mountain.

A witness stated he and a friend were on Cross Mountain scouting for deer when an airplane flew over their location at a very low altitude. The airplane flew into the valley and made about six steep left turns at about 45-degrees angle of bank. The airplane was so low that the witness could see the people in the airplane waving at them. The airplane flew back over their location at about 1620, flew back into the valley, and was observed to make another steep turn to the left before the airplane disappeared from view. They heard the engine go wide open and then heard a sound a few seconds later like trees popping.
