## Probable cause

FAILURE OF THE PILOT TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRCRAFT DURING LANDING.  THE ADVERSE WIND CONDITION AND THE PILOT'S LACK OF TOTAL EXPERIENCE WERE RELATED FACTORS.

## 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
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
- On ground/water collision with object, landing - roll
  - airport facilities,runway/landing area condition - sign

## Analysis

THE PLT SAID THAT WHILE ATTEMPTING TO LAND, THE ACFT WAS BLOWN TO THE LEFT OF THE RUNWAY BY A GUST OF WIND. THE ACFT STRUCK AN AIRPORT SIGN, DAMAGING THE LEFT HORIZONTAL STABILIZER. THE PILOT INITIALLY CONSIDERED A GO-AROUND, BUT WAS ABLE TO REALIGN THE AIRPLANE WITH THE REMAINING RUNWAY AND LAND WITHOUT FURTHER INCIDENT.
