Narrative:The aircraft crashed into the Kiroli Hills while on approach to Bombay at night.
PROBABLE CAUSE: Combination of the following factors:
(1) Momentary/intermittent loss of electrical contact in G/S system of aircraft which gave the pilot an erroneous impression of the interception of the glide slope;
(2) Failure of the pilot to discharge his obligations under DOC 4444 by failing to use the glidepath facility only after the Outer Marker and also in descending below 2910 feet without first cross-checking over the Outer Marker;
(3) Failure of the radar controller to discharge his obligations under DOC 4444 of giving position information to the aircraft from time to time, use of incorrect and/or non-standard phraseology and also failure to inform the aircraft about the loss of radar contact.
