Circumstances:
The aircraft departed during a break in the weather after having waited for a special VFR departure. His departure radio call was the last communication from the flight. The weather remained marginal with icing in the clouds and freezing drizzle. The aircraft was on a flight to transport a dentist and a technical assistant to area villages for US Health Dpt clinical work. There was no pressing or urgent need to adhere to a schedule if the weather dictated a postponement. Aircraft wreckage was located on the side of a mountain at 650 feet above msl. It had collided with an upgrade while in a descending turn. The aircraft broke apart and left wreckage for a distance of 493 feet before coming to rest. The pilot and one passenger remained in the wreckage. The right front passenger was ejected and located near the wreckage. Witnesses at the crash site noted ice 1/8 to 3/4 inches thick on the broken wings and airframe parts during the recovery.
