ANCHORAGE (KTUU) - The National Transportation Safety Board released its preliminary report on the deadly plane crash in Moose Pass on Friday, June 28.
NTSB says the aircraft, a Maule M6, was flying from Seward and heading to Anchorage when it crashed into a mountain.
Some key takeaways from the preliminary report:
- The discovery of a Garmin GPSMAP 496 GPS receiver, capable of storing route-of-flight data.
-Through the discovery of the GPS, NTBS was able to map the plane’s flight path.

After passing the intersection of the Sterling and Seward Highways, a right 180° turn was initiated to the southeast, and shortly thereafter, the airplane began a descent an altitude of 1,215 feet. It then turned to the north, gained altitude to 2,032 feet. The last fully recorded in flight data point was taken at 4:08:01 p.m. from an altitude of 1,587 feet. and a 0 mph groundspeed.
Those killed are said to be the pilot, 73-year-old Michael Scott Christy and his wife, 69-year-old Jean Tam, both from Anchorage, along with 29-year-old Suzanne Glass from Sterling, Virginia.
Troopers say 28-year-old Andrea Joy Cooper is the sole survivor of the crash.
