Probable cause
Inadequate compensation for wind conditions by the (private rated) dual student and his failure to maintain directional control, which resulted in an inadvertent ground swerve, and inadequate supervision by the instructor pilot (CFI). A factor related to the accident was: the unfavorable wind conditon.
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 instructor (CFI) and a private rated dual student were performing a familiarization flight. The CFI said the dual student made several touch and go landings on rwy 26L, with winds estimated by the CFI as being from 270 deg at 15 gusting 25 KTS. The CFI reported that during the last touchdown, the acft was angled to the left. The plane departed the rwy to the left and the horizontal stabilizer struck a rwy light, resulting in substantial damage.
