## Probable cause

THE PILOT'S IMPROPER IFR OPERATION IN ATTEMPTING AN ILS APPROACH IN AN AIRPLANE NOT EQUIPPED WITH AN ILS GLIDE SLOPE RECEIVER. THE WEATHER CONDITIONS WERE FACTORS IN THE ACCIDENT.

## 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)
  - weather condition - obscuration (contributing factor)
  - weather condition - fog (contributing factor)
  - weather condition - below approach/landing minimums (contributing factor)
  - comm/nav equipment,glide slope receiver - not installed (contributing factor)
  - ifr procedure - improper, pilot in command (cause)

## Analysis

THE PILOT HAD BEEN CLEARED FOR THE ILS APPROACH TO RUNWAY 24. HE TERMINATED THE FIRST APPROACH DUE TO AN 'AUTOPILOT PROBLEM.' HE WAS THEN VECTORED FOR THE SECOND APPROACH, AND SHORTLY AFTER REPORTING THE LOCATOR OUTER MARKER INBOUND RADIO COMMUNICATION WAS LOST. THE PUBLISHED CROSSING ALTITUDE AT THE MARKER IS 1,600 FEET. NTAP DATA REVEALED THE AIRPLANE CROSSED THE MARKER AT 800 FEET. THE AIRPLANE WAS NOT EQUIPPED WITH A GLIDE SLOPE RECEIVER/INDICATOR.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
