## Probable cause

THE STUDENT PILOT'S FAILURE TO MAINTAIN AIRCRAFT CONTROL. FACTORS RELATED TO THIS ACCIDENT WERE THE PILOT'S POORLY PLANNED APPROACH, FAILURE TO MAINTAIN THE PROPER GLIDE PATH, DELAY IN RAISING THE FLAPS, AND THE IMPROPER USE OF THE CARBURETOR HEAT.

## Sequence of events

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

- Loss of control - in flight, go-around (vfr)
  - aircraft control - not maintained, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - planned approach - poor, pilot in command (contributing factor)
  - proper glidepath - not maintained, pilot in command (contributing factor)
  - raising of flaps - misjudged, pilot in command (contributing factor)
  - carburetor heat - improper use of, pilot in command (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE STUDENT PILOT WAS EXECUTING TOUCH AND GO TAKEOFFS AND LANDINGS.  WHILE ON FINAL APPROACH THE STUDENT PILOT FAILED TO MAINTAIN THE PROPER GLIDEPATH AND GOT TOO LOW AND EXECUTED A GO AROUND.  THE AIRPLANE WAS CONFIGURED WITH FULL FLAPS AND THE CARBURETOR HEAT WAS ON.  THE STUDENT PILOT ADDED POWER WITHOUT TURNING OFF THE CARBURETOR HEAT AND THE AIRPLANE PITCHED UP.  HE THEN RETRACTED THE FLAPS WITHOUT SUCCESS.  THE AIRPLANE STALLED AND CRASHED ABOUT 1/4 MILE SHORT OF THE RUNWAY.

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.
