The Hawker was off-loading fuel at the Sandy Lake Airport when something went wrong and the plane caught on fire.
Regional Manager of the Transportation Safety Board Peter Hildebrand says they are trying to find out what exactly went wrong.
Hildebrand says he hopes to speak with the two crew members in the next day or so and get more information on what possibly caused the fire.
The TSB is also talking with Wasaya officials.
Meantime, a Sandy Lake First Nations firefighter says yesterday's fire could have been a lot worse.
Ringo Fiddler says firefighters received the call just before 2 o'clock in the afternoon and it took about 5-minutes for crews to arrive.
Fiddler says flames were shooting as high as 40-feet into the air and full fuel tanks were about 25-feet away.
He says firefighters had to fight the fire about 50-feet away from the blaze.
Fiddler says the fire started near the fuel tank.
No one was injured in the incident.
