## Probable cause

THE PILOT'S FAILURE TO PROPERLY ADHERE TO THE PUBLISHED INSTRUMENT APPROACH PROCEDURE WHICH RESULTED IN DESCENT BELOW THE MINIMUM DESCENT ALTITUDE. FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE THE LOW CEILING AND FOG.

## Sequence of events

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

- In flight collision with object, approach - faf/outer marker to threshold (ifr)
  - weather condition - low ceiling (contributing factor)
  - weather condition - fog (contributing factor)
  - ifr procedure - improper, pilot in command (cause)
  - object - tree(s)

## Analysis

THE AIRPLANE DISAPPEARED FROM RADAR ABOUT 1-1/2 MI SHORT OF THE AIRPORT DURING A VOR RUNWAY 13 APPROACH. RADAR DATA SHOWS THAT THE ALTITUDES, DESCENT RATES, AND GROUND SPEEDS WERE CONSISTENT WITH THE APPROACH PROFILE. THE LAST RADAR POSITION OF THE AIRPLANE WAS AT 100 FT ON THE RUNWAY EXTENDED CENTERLINE. THE DEBRIS PATH WAS ALIGNED ON A 130 DEG MAG HEADING. WITNESSES STATED THAT THE VISIBILITY WAS NEAR ZERO IN FOG.

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.
