TSB spokesman Bill Yearwood said they’ll be looking at factors including pilot training, weather and the condition of the plane.

He says investigators hope to find flight any data recorders, expected to provide an update on the investigation.

Beverly Harvey, the investigator in charge, said “the aircraft was not equipped with, nor was it required to carry a cockpit voice recorder or a flight data recorder or a flight data recorder.”

“However, the team will be reviewing any electronic components on the aircraft from which we can retrieve any data to help understand the flight profile,” Harvey said. “The initial examinations suggests the aircraft was destroyed from high deceleration forces after a vertical descent. There were no emergency or distress calls made. No emergency locator transmitter signal was received.”

Photos of the crash site were released by the TSB Saturday.

“The current site, is currently under the control of the BC Coroner Service. The TSB has been granted access to the site. There are currently five TSB investigators on this site. The coroner still has control of the site, the victims are still there,” Harvey said.

Harvey said she “would like to have this investigation completed within one year.”

The aircraft, meantime, has been identified as a Cessna Citation that was built in 1974.

A preliminary Transport Canada report says it climbed to 8,600 feet before disappearing from radar.

Norjet says it will fully-co-operate with the Transportation Safety Board investigation.
