## Probable cause

THE DUAL STUDENT'S INADEQUATE COMPENSATION FOR WIND CONDITIONS AND INADEQUATE SUPERVISION BY THE FLIGHT INSTRUCTOR. FACTORS WERE: WIND GUSTS, WIND SHEAR AND TURBULENCE.

## Sequence of events

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

- Loss of control - in flight, approach - vfr pattern - final approach
  - weather condition - gusts (contributing factor)
  - weather condition - turbulence (contributing factor)
  - weather condition - windshear (contributing factor)
  - supervision - inadequate, pilot in command(cfi) (cause)
  - compensation for wind conditions - inadequate, dual student (cause)
  - aircraft control - not maintained, dual student (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE COMMERCIAL DUAL STUDENT AND CFI WERE PERFORMING A VISUAL APPROACH. THE STUDENT WAS AT THE CONTROLS AND IN THE LEFT SEAT. THEY WERE AWARE OF WIND SHEAR ALERTS AT A NEARBY AIRPORT, AND MODERATE TURBULENCE WAS OBSERVED ON FINAL APPROACH PRIOR TO THE ACCIDENT. AT ABOUT 30 FEET AGL, THE NOSE DROPPED SHARPLY. BOTH PILOTS INITIATED A GO AROUND, HOWEVER THE AIRCRAFT COLLIDED WITH THE RUNWAY IN A NOSE HIGH ATTITUDE. THE PILOTS REPORTED NO MECHANICAL PROBLEMS WITH THE AIRPLANE.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19920319007039A](https://openairdocs.org/incident/19920319007039A), Mar 19, 1992: Piper PA44180, Marietta, GA, Substantial damage. Simulated engine out. Aircraft pitched down on short final. Began nose high go around. Tail hit. Control was lost.

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.
