N89B – CLASSIC AIRCRAFT CORP WACO YMF – 2009-11-16 NTSB Accident Report

On November 16, 2009, a Classic Aircraft Corp WACO YMF (N89B) was involved in an incident near Dunnellon, FL. All 2 people aboard were uninjured. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this incident to be: The certified flight instructor’s delayed response to the student pilot's loss of directional control while landing, which resulted in a ground-loop. Contributing to the accident was the student pilot's loss of directional control.

The student pilot was receiving instruction in a tailwheel equipped biplane from a certified flight instructor (CFI). During the second landing, the student pilot landed the airplane on the runway fast and bounced; the airplane started to veer left. The student pilot corrected with right rudder application. The CFI applied full left rudder when the airplane veered to the right again, which had no effect on the airplane’s direction of travel; the student pilot then applied right brake during the CFI’s correction. The airplane continued right until it ground-looped. The biplane incurred substantial damage to both upper wings and left lower wing. The flight crew reported no mechanical deficiencies prior to the accident.

This incident is documented in NTSB report ERA10CA076. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N89B.
