NTSB description


On December 13, 1995, at 1816 Pacific standard time, N5GM, a Cessna 340A, was destroyed when it collided with terrain at Mount Spokane, near Mead, Washington. The commercial pilot, who was the sole occupant of the aircraft, was fatally injured. The aircraft had departed Spokane International airport at 1806 and was operating under 14 CFR 91 at the time of the crash. The pilot was en route on the business flight to pick up his employer at Sandpoint, Idaho. No flight plan was filed for the flight. According to a pilot who was vectored to the vicinity of the accident about ten minutes after the occurrence, instrument meteorological conditions prevailed at the accident site. No ELT signal was reported, and no ELT was found at the accident site.

According to N-TAP radar data, the aircraft was maintaining a constant heading and 5600 feet altitude from 1811:03 until 1815:41, with no heading or altitude changes observed before impacting with the 5867 foot peak. An altimeter found at the site read 5520 feet.

The pilot was in contact with Air Traffic Control throughout his flight. Extracts of the transcript follow. The complete transcript is attached.

After departure from Spokane, the pilot established communications with the East Radar Controller at Spokane Approach Control, checking in at 1809:15. At 1809:30, the controller confirmed radar contact and asked the pilot to verify his level- off altitude. The pilot stated "...five thousand five hundred."

At 1810:34, the controller stated "...we show an IFR flight plan filed off Spokane going to Yakima. Do you still want to pick that up or do you want us to move it over to Sandpoint?" The pilot stated "I'd like to move that over to Sandpoint; we had a change of plans at the last minute."

Between 1810:34 and 1814:50, there were several communications exchanges between the pilot and radar controller concerning flight planning. At 1814:50, the controller asked the pilot to verify that his destination was Yakima. The pilot responded "That's affirmative; destination is Yakima."

There were no further communications from N5GM.

At 1817:21, the controller attempted to advise the pilot that he could pick up his IFR clearance off Sandpoint. There was no response. The controller had another aircraft attempt to establish communications.


The crew of an aircraft vectored to the vicinity of the accident shortly after the accident stated that instrument meteorological conditions were encountered in the vicinity of Mount Spokane.


The wreckage was found on the south face of Mount Spokane, on a slope estimated at 30 degrees upslope. The wreckage distribution path was approximately 800 feet from initial impact to the final pieces along the path. A multitude of small parts and pieces were scattered along the distribution path, which was estimated to be oriented about 30-40 degrees magnetic. The following description does not detail all pieces identified, but is limited to larger pieces. At the initial impact point, four craters were found dimensionally separated by distances similar to the dimensions between the engines and wing tip tanks. Ninety-six paces from the craters, the empennage was found. The rudder was displaced to the right, and the right elevator trim tab was down. The left elevator surface was partially separated from the horizontal stabilizer. About eight feet of the aft fuselage and tailcone, which were crushed and folded, remained attached to the empennage. A road was immediately upslope of the empennage. Further upslope, at 148 paces, a propeller blade was found; at 180 paces, an aileron was found. At 200 paces, two propeller blades were found. At 265 paces, a propeller with three blades was found. A few paces further, and about fifty feet upslope of that propeller, an engine, SN290589-R (the right engine, according to log book entries), was found. At 275 paces, and about 30 paces downslope, an engine, SN 276759-R (the left engine according to log books) was found. The right wing was found at 300 paces, and the fuselage was found at 350 paces.

The fuselage exhibited torn skin at the aft pressure bulkhead, with the tailcone completely separated. The forward fuselage exhibited extensive crushing aft to the leading edge of the wing. The right wing center section, out to the nacelle, remained attached to the fuselage. The left wing, extensively crushed, remained attached to the inboard left wing center section, and the nacelle remained attached. The fuselage section was resting about 180 degrees from the wreckage distribution path.

All propeller blades exhibited extensive leading edge and tip damage, with chordwise scratching. Control cable continuity could not be established due to the separation of aircraft components, however control cable continuity was established from the separated cables to the elevator and rudder horns.


An autopsy of the pilot was performed by Drs. Lindholm and Venzon at the Forensic Institute, and Holy Family Hospital, Spokane, Washington, on December 14 and 15, 1995.

Toxicological testing was performed by the Washington State Toxicology Laboratory. Blood ethanol was negative, and carbon monoxide was under 5% saturation.


The Safety Board did not assume possession of the wreckage. Subsequently, a release form was not required or signed. The wreckage was removed from the site and placed in storage at Discount Air Salvage, Deer Park, Washington.
