NTSB releases prelim report on deadly Moose Pass plane crash


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.

-The NTSB report says visibility at the time was 7 miles.

With this data, officials are able to map out minute by minute where the plane was and its altitude.

Looking at the flight path the GPS provided, you can see the plane was heading northwest along the Sterling Highway at various GPS altitudes. 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.

When the crash was reported, the Air National Guard's 210th Air Rescue Squadron responded. An Air National Guard HH-60G helicopter crew discovered the accident site, and Cooper was subsequently evacuated.

NTSB says she was taken to a medical facility in Anchorage.

Officials say a detailed wreckage examination is pending following the recovery of the airplane.
