## 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
  - compensation for wind conditions - improper, pilot in command (contributing factor)
- On ground/water collision with object, landing - roll
  - object - runway light (contributing factor)
  - remedial action - improper, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (cause)

## Analysis

DURING A VFR CROSS COUNTRY FLT, WX CONDITIONS ALONG THE ROUTE INDUCED THE PLT TO DIVERT TO THE ANGWIN ARPT. AFTER AN OVERFLT TO OBTAIN WIND INFORMATION FROM THE WIND SOCK, THE PLT SAID HE ENTERED THE PATTERN AND COMPLETED A NORMAL APPROACH AND TOUCHDOWN. SHORTLY AFTER TOUCHDOWN, THE PLT STATED THAT HE 'GOT CAUGHT BY A GUST (OF) CROSSWIND AND STRUCK (A) WINGTIP ON (A) RUNWAY LIGHT WHILE COMPENSATING FOR (THE) CROSS WIND.' THE PLT ESTIMATED THE WINDS AS FROM 270 DEGREES AT 10 KTS WITH GUSTS TO 20 KTS. THE CLOSEST OFFICIAL WX REPORTING STATION (18 NM WEST) REPORTED WINDS FROM 170 DEGREES AT 5 KTS.
