Accident occurred Monday, October 11, 1993 in GREEN VALLEY, CA
Probable Cause Approval Date: 09/13/1994
Aircraft: NORTH AMERICAN T-6G, registration: N7765C
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 CFI planned to check out his student, who was a foreign country airline pilot, in the North American T-6G. The CFI planned to fly in a northward direction to Lancaster, which required traveling over rising mountainous terrain. At departure, a broken ceiling existed with a 3,000-foot msl base. Witnesses observed the northbound T-6G flying below the clouds and maneuvering up a canyon. Seconds before the airplane made a 180-degree course reversal turn and impacted the side of a mountain, it was observed flying in a northward direction 100 to 200 feet over a home and just below the cloud bases. The visibility was estimated at 0.25 miles, and the crash site elevation was about 3,600 feet msl.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

the CFI's failure to maintain the proper altitude while flying over mountainous terrain, and his inadvertent flight into instrument weather conditions. Contributing factors were the CFI's improper in-flight decision to fly at the low altitude and his misjudged evaluation of the weather.
