History of Flight
On 20 March 2008 at approximately 1250Z, an instructor and a student pilot were conducting circuit training at Brakpan Benoni Aerodrome (FABB) in a Piper PA-28-140 aircraft, registration ZS-FAC. The first approach and landing were uneventful, though the student had difficulty maintaining the runway centre line. During the second approach, the student abruptly applied full left rudder, causing an abrupt left yaw. The instructor applied corrective right rudder without informing the student that she had taken control. The student also applied full right rudder to correct the left yaw, resulting in both pilots applying right rudder simultaneously. The aircraft landed hard on the nose gear, causing the nose gear to collapse. The aircraft veered to the right and the propeller struck the ground.
Aircraft Damage
The aircraft sustained damage to the nose landing gear, the bottom nose section, and the propeller. No other damage was reported.
Personnel Information
The instructor, a 31-year-old female, held a valid Commercial Pilot Licence with Instrument and Instructor (Grade III) ratings. She had 950 total flying hours, including 59 hours on the PA-28-140, but had not flown the type in the previous 90 days. The student, a 19-year-old female, held a valid Student Pilot Licence and had 25.8 total flying hours, with 15.2 hours on type.
Meteorological Information
Weather conditions were fine, with wind from 180 degrees at 6 knots, visibility CAVOK, temperature 27°C, and no cloud cover.
Aerodrome Information
Brakpan Benoni Aerodrome is an unregistered airfield with a single runway designated 18/36, measuring 1440 metres by 15 metres, surfaced with tar. The accident occurred on Runway 18.
Additional Findings
It was noted during the investigation that the aircraft did not have brakes installed on the instructor's side. No system or engine malfunctions were identified.
Probable Cause
The accident was attributed to a hard landing resulting from both pilots manipulating the controls simultaneously, both applying right rudder. A contributory factor was the instructor's failure to intervene in time to rectify the situation when the student was losing control.
