The pilot was a 76 year old woman and the passenger a 74 year old man.
The plane had been missing all evening and should have landed at Ursel Airstrip at 5pm.
Landing had to be postponed due to the sudden snowfall.
A Federal Police helicopter and a Belgian Navy Sea King were used in the search for the missing plane.
Wreckage and two bodies were eventually found in woodland near to Ursel.
