Suspicion of mid flight explosion arose when the cargo hold area were recovered from the wreckage. Pieces of burnt fuselage parts of the left side of the underbelly of the aircraft were found approximately 100 feet away from the crater created by the impact of the aircraft with the ground. The burnt parts contained a portion of the registration number and another section of the skin with the other part of the registration number. The two pieces matched and were suspected to emanate from the left side of the fuselage.
