From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(.4)After two unsuccessful power-off landing attempts at a short field, the CFI took control of the tail wheel airplane to demonstrate the proper technique. On short final, the CFI told the pilot to "guard the controls", who then placed his hands and feet near the controls. The CFI stated that he wanted the other pilot to correct any erroneous inputs during the landing. The airplane drifted right on touchdown, and the CFI responded with left rudder. The CFI reported that the rudder would move only about 1 inch, when it suddenly 'let go', and full left rudder was applied. The airplane immediately went left, and with little remaining runway, the CFI kicked 'full right rudder to intentionally ground loop the airplane'. The pilot stated that he did not feel the binding. The CFI had a total of 36 hours inmake and model, none in the 90 days. Removal of the floor panels and a examination of the rudder cables verified proper installation, and no 'witness marks' of binding controls were found. (-23) pilot lost control on landing and ground loop the aircraft.

As the FAA filed it

(.4)AFTER TWO UNSUCCESSFUL POWER-OFF LANDING ATTEMPTS AT A SHORT FIELD, THE CFI TOOK CONTROL OF THE TAIL WHEEL AIRPLANE TO DEMONSTRATE THE PROPER TECHNIQUE. ON SHORT FINAL, THE CFI TOLD THE PILOT TO "GUARD THE CONTROLS", WHO THEN PLACED HIS HANDS AND FEET NEAR THE CONTROLS. THE CFI STATED THAT HE WANTED THE OTHER PILOT TO CORRECT ANY ERRONEOUS INPUTS DURING THE LANDING. THE AIRPLANE DRIFTED RIGHT ON TOUCHDOWN, AND THE CFI RESPONDED WITH LEFT RUDDER. THE CFI REPORTED THAT THE RUDDER WOULD MOVE ONLY ABOUT 1 INCH, WHEN IT SUDDENLY 'LET GO', AND FULL LEFT RUDDER WAS APPLIED. THE AIRPLANE IMMEDIATELY WENT LEFT, AND WITH LITTLE REMAINING RUNWAY, THE CFI KICKED 'FULL RIGHT RUDDER TO INTENTIONALLY GROUND LOOP THE AIRPLANE'. THE PILOT STATED THAT HE DID NOT FEEL THE BINDING. THE CFI HAD A TOTAL OF 36 HOURS INMAKE AND MODEL, NONE IN THE 90 DAYS. REMOVAL OF THE FLOOR PANELS AND A EXAMINATION OF THE RUDDER CABLES VERIFIED PROPER INSTALLATION, AND NO 'WITNESS MARKS' OF BINDING CONTROLS WERE FOUND. (-23) PILOT LOST CONTROL ON LANDING AND GROUND LOOP THE AIRCRAFT.
