Summary
On July 30, 2011, a Cessna 170A (N9741A) was involved in an incident near Mulino, OR. All 3 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 inadequate oversight of his student, and delayed recovery efforts following the student's loss of directional control during landing rollout.
The certified flight instructor (CFI) reported that the purpose of the flight was, in part, to provide the private pilot with recurrent training in furtherance of obtaining a flight review. The student was not current. Following performance of basic airwork in the conventional gear airplane, the CFI asked the student to perform a wheel landing. The CFI said that the student’s landing was successfully performed, but during rollout he exhibited a directional control deficiency. The airplane veered right during rollout on the subsequent landing, and the student attempted to regain directional control. The CFI reported that, due to his lengthy personal relationship with the student, he delayed acquiring control of the airplane.
This incident is documented in NTSB report WPR11CA355. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N9741A.

Analysis
The certified flight instructor (CFI) reported that the purpose of the flight was, in part, to provide the private pilot with recurrent training in furtherance of obtaining a flight review. The student was not current. Following performance of basic airwork in the conventional gear airplane, the CFI asked the student to perform a wheel landing. The CFI said that the student’s landing was successfully performed, but during rollout he exhibited a directional control deficiency. The airplane veered right during rollout on the subsequent landing, and the student attempted to regain directional control. The CFI reported that, due to his lengthy personal relationship with the student, he delayed acquiring control of the airplane. By the time he took the controls, it was too late to avoid the impending ground loop. As the airplane came to a stop on the runway’s gravel shoulder, the left main landing gear separated from the gear box, and the left wing broke.
