Abstract

A Boeing 737 passenger aircraft suffered a mid-air explosion in the front toilet area during a scheduled flight and forced the pilot to make an emergency landing. In that process the aircraft overshot the runway damaging its undercarriage and underside. To determine the primary cause of explosion and its exact location, extensive fractographic examination was carried out on the fragments found near the explosion area. These fragments contained signatures characteristic of explosive fracture. The exact location of these fragments in the original aircraft structure was identified. It was concluded that the accident was due to a chemical explosion inside the front toilet of the aircraft. By tracing the trajectories of the projectiles flying in various directions following the explosion, the centre of the explosion, i.e., the location of the explosive device in the aircraft was established to be the waste paper receptacle placed under the wash basin.
