## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AIRCRAFT CONTROL DURING THE LANDING PHASE OF THE FLIGHT. FACTORS WERE: GUSTING WIND CONDITIONS AND TURBULENCE.

## Sequence of events

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

- Dragged wing,rotor,pod,float or tail/skid, landing - flare/touchdown
  - weather condition - gusts (contributing factor)
  - weather condition - turbulence (contributing factor)
  - aircraft control - not maintained, pilot in command (cause)
- In flight collision with terrain/water, landing - flare/touchdown

## Analysis

WHILE ON FINAL APPROACH FOR LANDING, THE PILOT REPORTED THAT A GUST OF WIND WAS ENCOUNTERED. DESPITE FLIGHT CONTROL INPUTS TO COUNTERACT THE WIND, A WINGTIP DRAGGED THE GROUND, AND THE GLIDER BROKE UP. THE PILOT STATED THAT IT WAS ABOUT 101 DEGREES AT THE TIME, AND THE AIR WAS ROUGH AND TURBULENT. HE ALSO REPORTED THAT GLIDER OPERATIONS AT THE AIRPORT WERE CANCELLED THE NEXT DAY DUE TO THE ROUGH AIR. HE REPORTED NO MECHANICAL PROBLEMS WITH THE GLIDER.

## 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 19900826035989A](https://openairdocs.org/incident/19900826035989A), Aug 26, 1990: Brasov IS28B2, Savannh, TN, Substantial damage. Turbulence on short final. A wing dipped and caught the ground causing glider to cartwheel.

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.
