## Probable cause

THE PILOT-IN-COMMAND'S FAILURE TO MAINTAIN A PROPER GLIDEPATH.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- In flight collision with terrain/water, approach - faf/outer marker to threshold (ifr)
  - light condition - dark night (contributing factor)
  - weather condition - fog (contributing factor)
  - weather condition - low ceiling (contributing factor)
  - proper glidepath - not maintained, pilot in command (cause)

## Analysis

DURING THE SECOND ILS APPROACH THE AIRPLANE DESCENDED BELOW THE GLIDEPATH AND IMPACTED THE TERRAIN 2,500 FEET SHORT OF THE INTENDED LANDING RUNWAY. THE PILOT INDICATED THAT A FAILURE IN THE APPROACH LIGHTING SYSTEM CONTRIBUTED TO THE ACCIDENT.  A POST ACCIDENT FUNCTIONAL CHECK OF THE APPROACH LIGHTING SYSTEM FAILED TO REVEAL ANY ANOMALIES.
