NTSB Identification: ERA14CA140
14 CFR Part 91: General Aviation
Accident occurred Saturday, March 01, 2014 in Mayaguez, PR
Probable Cause Approval Date: 05/21/2014
Aircraft: PIPER PA 18-150, registration: N929SC
Injuries: 1 Minor, 1 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

According to a written statement provided by the pilot to a Federal Aviation Administration inspector, he performed a three-point landing in the tailwheel equipped airplane. The airplane "bounced two times," and then it veered to the right. According to a written statement from the passenger, the "approach was normal, [but the] problems started after touchdown." The airplane turned to the right, the pilot initiated a go around; however, the left wing rose up, and the airplane "lost control" to the right. The airplane came to rest in the grass on the right side of the runway, and incurred substantial damage to the firewall and fuselage. A postaccident examination of the airplane revealed no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's loss of directional control of the airplane during landing, which resulted in a runway excursion.

Accident occurred Saturday, October 15, 2011 in Deland, FL
Probable Cause Approval Date: 02/06/2012
Aircraft: PIPER PA-18-150, registration: N929SC
Injuries: 1 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot was practicing a three point landing in the tailwheel-equipped airplane when the airplane veered to the left after touchdown. The pilot stated that when he tried to correct to the right, he heard an abnormal noise from the tailwheel, and the tailwheel locked. Examination of the accident site revealed that the airplane had exited the right side of the runway, hit a taxiway sign, traveled 50 more yards, and nosed over. Examination of the airplane revealed that the fabric was torn in numerous places, the propeller was broken, the forward left wing strut was bent, the right landing gear was broken and bent up under the fuselage, and the fuselage was twisted. The examination revealed no evidence of any preimpact failure or malfunction of the flight controls; the tailwheel moved freely to the left and right with rudder pedal application, and no binding was noted.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's inadequate directional control during the landing roll.

While practicing three point takeoffs and landings in the tail wheel equipped airplane for a Federal Aviation Administration (FAA) required examination, the pilot experienced a loss of control when the airplane veered to the left after touchdown. The pilot stated that he tried to correct to the right but that he heard an abnormal noise from the tailwheel and then it locked. Examination of the accident site by an FAA inspector revealed that the airplane had run off the right side of the runway, hit a taxiway sign, traveled 50 more yards, and nosed over. Examination of the airplane revealed that its airframe was substantially damaged. The fabric was torn in numerous places, the propeller was broken, the forward left wing strut was bent, the right landing gear was broken and bent up under the fuselage, and the airframe exhibited evidence of torsional deformation. Further examination revealed no evidence of any preimpact failure or malfunction of the flight controls. No binding was discovered and the tailwheel would move freely to the left and right with rudder pedal application.
