## Probable cause

THE PILOT IN COMMAND'S IMPROPER INFLIGHT DECISION AND THE MINIMUM DESCENT ALTITUDE DISREGARDED DURING AN INSTRUMENT APPROACH.

## 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)
  - object - tree(s)
  - in-flight planning/decision - improper, pilot in command (cause)
  - minimum descent altitude - disregarded, pilot in command (cause)
- Loss of control - in flight, approach - iaf to faf/outer marker (ifr)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE ACCIDENT AIRPLANE COLLIDED WITH TREES AND TERRAIN AFTER BEING CLEARED FOR A NONPRECISION INSTRUMENT APPROACH. INSTRUMENT METEOROLOGICAL CONDITIONS PREVAILED.  THE MINIMUM DESCENT ALTITUDE FOR THE APPROACH PROFILE FROM AN INTERMEDIATE INTERSECTION TO THE MISSED APPROACH POINT IS 1,460 FEET.  THE ELEVATION OF DESTINATION AIRPORT IS 745 FEET.  THE ELEVATION OF THE ACCIDENT SITE IS 880 FEET.  TWO PERSONS WITNESSED THE ACCIDENT SEQUENCE.  BOTH PERSONS SAW THE AIRPLANE IN LEVEL, LOW ALTITUDE FLIGHT WITH THE LANDING GEAR DOWN BEFORE IT STRUCK THE TREE TOPS.  THEY DESCRIBED HOW THE AIRPLANE PULLED UP AND THEN ROLLED BEFORE IT STRUCK THE GROUND.  ONE WITNESS DESCRIBED HOW THE AIRPLANE WAS FLYING AT THE BASE OF THE CLOUDS.

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.
