## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (cause)
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
- In flight collision with object, landing
  - go-around - attempted, pilot in command
  - airspeed(vso) - not attained, pilot in command (cause)
  - stall - inadvertent, pilot in command
  - object - fence (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

PLT HAD EXECUTED SUCCESSFUL CROSSWIND LANDING AND WAS DECELERATING ON ROLL-OUT WHEN A GUST OF WIND CAUSED THE ACFT TO SWERVE INTO THE WIND. DIRECTIONAL CONTROL COULD NOT BE REGAINED WITH RUDDER SO PLT ELECTED TO ATTEMPT GO-AROUND. ACFT BECAME AIRBORNE IN GROUND EFFECT, STALLED, AND THE LEFT WING DROPPED, STRIKING AN AIRPORT FENCE.

## 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 19841020057429A](https://openairdocs.org/incident/19841020057429A), Oct 20, 1984: Namer HARVARDMK4, Apple Vlley, CA, Substantial damage. Combination of prop wash and gusty crosswind caused partial loss of control. Tried to go around and struck a fence.

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.
