## Probable cause

THE PILOT-IN-COMMAND'S (CFI) INADEQUATE SUPERVISION OF THE DUAL STUDENT PILOT AND THE DUAL STUDENT'S INADVERTENT APPLICATION OF THE BRAKES.

## Sequence of events

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

- In flight collision with object, takeoff - initial climb
  - touchdown - inadvertent, dual student
  - brakes(normal) - inadvertent activation, dual student (cause)
  - supervision - inadequate, pilot in command(cfi) (cause)
  - aborted landing - initiated, pilot in command(cfi)
  - object - tree(s)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE FLIGHT INSTRUCTOR WAS TRAINING THE PRIMARY STUDENT IN DETERMINING FLARE HEIGHT.  DURING A LOW PASS DOWN THE RUNWAY, THE AIRPLANE'S MAIN WHEELS TOUCHED THE RUNWAY, SEVERAL TIMES, WITH THE STUDENT INADVERTENTLY APPLYING BRAKES. THE INSTRUCTOR ATTEMPTED TO ABORT THE INADVERTENT LANDING BY APPLYING FULL POWER, AND REDUCING THE FLAPS FROM 30 DEGREES TO 10 DEGREES; HOWEVER, THE AIRPLANE DID NOT CLEAR TREES 200 YARDS BEYOND THE DEPARTURE END OF THE 3,500 FOOT LONG RUNWAY.  THE AIRPLANE IMPACTED THE TREES AND DESCENDED INTO THE TERRAIN.

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.
