What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The CFI and student pilot (sp) was cleared for takeoff at khio runway 31L at approximately 1555 PST in privacy data omitted, CE-152. The sp was performing the takeoff while the CFI was monitoring.
The sp slowly added power and the takeoff was initiated. The CFI had the controls guarded. Approx 2-3 seconds after the power was added the CFI side door opened. The CFI momentarily glanced to look over at the door when the sp did not let the nose down enough and the tail skid strike occurred. Both CFI and sp noticed the tailstrike immediately and the CFI took controls and aborted the takeoff. Khio tower was contacted and notified of the aborted takeoff and the aircraft successfully taxied off of the runway and back to the school.
