Détails:
On its way from Trivandrum to Madras, the aircraft was cleared to descent from FL270. Shortly afterwards an explosion took place in the forward lavatory, causing a complete instrument and electrical failure.
The Boeing had to make a flapless landing at Madras (now Chennai). The aircraft touched down 2500 feet past the runway 25 threshold and overran. The right side of the plane caught fire.

PROBABLE CAUSE: "Detonation of an explosive device in the forward lavatory of the aircraft. The aircraft overshot the runway due to high speed of touchdown, non-availability of reverse thrust and anti-skid system due to systems failure consequent on explosion."
