Accident Number: GAA17CA507
Date & Time: 08/24/2017, 0745 PDT
Registration: N599CC
Aircraft: CUB CRAFTERS INC CC11 100
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Instructional
Analysis
The student pilot of the tailwheel-equipped airplane was practicing crosswind takeoffs and landings with the flight instructor. During the second landing, a few feet above the runway on short final, the airplane's nose turned sharply to the left. The student reported that his flight instructor yelled a command, took over the controls, and added full power. The flight instructor reported that, after he took the flight controls, he attempted to go around but was unsuccessful. The airplane continued to the left through low brush and down an embankment. The tailwheel struck the edge of the embankment, and the airplane then nosed over.
Both wings and wing struts sustained substantial damage.
The student pilot and flight instructor reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
An automated weather observation station located about 7 miles north of the accident airport reported that, about 8 minutes after the accident, the wind was from 310° at 11 knots. The airplane landed on runway 2.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The student pilot's failure to maintain airplane control while landing in crosswind conditions and the flight instructor's delayed remedial action.
