Probable cause
Directional control was not maintained by the cfi/pic. Factors related to the accident were a gusty cross wind and an airport facility, VASI light.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The CFI said that while practicing takeoffs and landings with a dual student, in a crosswind, the airplane was caught by a wind gust and turned sideways. The CFI took over the controls, but was unable to regain directional control and veered off the runway colliding with a VASI light.
