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.

(-23) The pilot was landing on runway 07 at Grangeville 'S80' id. Upon roll out the pilot lost control of the aircraft. The aircraft exited the runway on the right side, proceeding into a ditch in which the right main gear struck a drainage gutter at the bottom of said ditch. The right main gear collapsed and subsequently the propeller contacted the ground causing a sudden stoppage of the aircraft engine. The pilot stated that, "normally his practice is to three point his landings, however, this landing, due to a lack of nose up trim, was on the main wheels and when the tail lowered to the ground, the pilot lost rudder effectiveness. At that point instead of adding power thereby increasing the airflow over the rudder, the pilot began to get behind the aircraft control requirements and eventually lost control leading to the exit from the runway."

As the FAA filed it

(-23) THE PILOT WAS LANDING ON RUNWAY 07 AT GRANGEVILLE 'S80' ID. UPON ROLL OUT THE PILOT LOST CONTROL OF THE AIRCRAFT. THE AIRCRAFT EXITED THE RUNWAY ON THE RIGHT SIDE, PROCEEDING INTO A DITCH IN WHICH THE RIGHT MAIN GEAR STRUCK A DRAINAGE GUTTER AT THE BOTTOM OF SAID DITCH. THE RIGHT MAIN GEAR COLLAPSED AND SUBSEQUENTLY THE PROPELLER CONTACTED THE GROUND CAUSING A SUDDEN STOPPAGE OF THE AIRCRAFT ENGINE. THE PILOT STATED THAT, "NORMALLY HIS PRACTICE IS TO THREE POINT HIS LANDINGS, HOWEVER, THIS LANDING, DUE TO A LACK OF NOSE UP TRIM, WAS ON THE MAIN WHEELS AND WHEN THE TAIL LOWERED TO THE GROUND, THE PILOT LOST RUDDER EFFECTIVENESS. AT THAT POINT INSTEAD OF ADDING POWER THEREBY INCREASING THE AIRFLOW OVER THE RUDDER, THE PILOT BEGAN TO GET BEHIND THE AIRCRAFT CONTROL REQUIREMENTS AND EVENTUALLY LOST CONTROL LEADING TO THE EXIT FROM THE RUNWAY."
