## Analysis

WHEN THE PLT RECEIVED LDG INSTRUCTIONS THE WIND WAS REPORTED AS BEING CALM. DURING LDG FLARE ON RWY 26, AT 2 FT AGL, A GUST WAS ENCOUNTERED. THE GUST WAS FROM THE ACFT'S 7 O'CLOCK POSITION & THE PLT WAS UNABLE TO MAINTAIN CONTROL OF THE ACFT. HE STATED THAT HE WAS 'JUST ALONG FOR THE RIDE.' THE ACFT TOUCHED DOWN & SLID OFF THE RWY. IT THEN WENT INTO A DITCH, COLLIDED WITH A BERM AND NOSED OVER. THE WIND WAS MEASURED AT 100 DEG, 12 KTS. THE PLT HAS 4475 TOTAL FLT HRS & 96 IN THIS MODEL ACFT.

## 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 19841206064549A](https://openairdocs.org/incident/19841206064549A), Dec 6, 1984: Univar 1082, Chino, CA, Substantial damage. Windshift as aircraft touched down forced aircraft off runway into a ditch. ATC verified windshift with gust.

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.
