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.

The pilot stated, the ?weather conditions at the time of the accident: winds 160 deg at 07 KTS. Clear below 12,000 feet. Temp 22 c/ 71 f. dewpoint 12 c/ 54F. 10 miles visibility.

The pilot stated ?I had previously done 5 takeoff and landings on this day prior to the accident.?

The pilot stated ?at approximately 12:45 pm I approached to land from the NE. Normal straight in landing. On roll out I pushed the right brake. At that moment the rudder pedal went forward flat on the floor. When it went flat there was a clunk. The right-hand brake master cylinder came apart, completely disabling the right brake. This made the rudder pedal lay flat on the floor. I needed right rudder or right brake to maintain directional control, but since the pedal was laying on the floor it was jamming against the hopper. I could not maintain directional control with rudder and the brake was inoperative. The aircraft slowly veered to the left side of the runway, off the runway, and into the ditch. As the aircraft went into the ditch it spun to the left, the propeller struck the terrain and came to a stop.?

The pilot stated ?there were no injuries.?

The pilot stated ?aircraft damage: the propeller suffered major damage from impacting the ground. The airframe suffered minimal damage. The left-hand wingtip has a small wrinkle from impacting the ground as well when the aircraft came to a stop. Two ?boom hangars?, which help support the agricultural dispensing system were bent beyond repair. They cause no damage to the airplane or to the control system.?

As the FAA filed it

THE PILOT STATED, THE ?WEATHER CONDITIONS AT THE TIME OF THE ACCIDENT: WINDS 160 DEG AT 07 KTS. CLEAR BELOW 12,000 FEET. TEMP 22 C/ 71 F. DEWPOINT 12 C/ 54F. 10 MILES VISIBILITY.

THE PILOT STATED ?I HAD PREVIOUSLY DONE 5 TAKEOFF AND LANDINGS ON THIS DAY PRIOR TO THE ACCIDENT.?

THE PILOT STATED ?AT APPROXIMATELY 12:45 PM I APPROACHED TO LAND FROM THE NE. NORMAL STRAIGHT IN LANDING. ON ROLL OUT I PUSHED THE RIGHT BRAKE. AT THAT MOMENT THE RUDDER PEDAL WENT FORWARD FLAT ON THE FLOOR. WHEN IT WENT FLAT THERE WAS A CLUNK. THE RIGHT-HAND BRAKE MASTER CYLINDER CAME APART, COMPLETELY DISABLING THE RIGHT BRAKE. THIS MADE THE RUDDER PEDAL LAY FLAT ON THE FLOOR. I NEEDED RIGHT RUDDER OR RIGHT BRAKE TO MAINTAIN DIRECTIONAL CONTROL, BUT SINCE THE PEDAL WAS LAYING ON THE FLOOR IT WAS JAMMING AGAINST THE HOPPER. I COULD NOT MAINTAIN DIRECTIONAL CONTROL WITH RUDDER AND THE BRAKE WAS INOPERATIVE. THE AIRCRAFT SLOWLY VEERED TO THE LEFT SIDE OF THE RUNWAY, OFF THE RUNWAY, AND INTO THE DITCH. AS THE AIRCRAFT WENT INTO THE DITCH IT SPUN TO THE LEFT, THE PROPELLER STRUCK THE TERRAIN AND CAME TO A STOP.?

THE PILOT STATED ?THERE WERE NO INJURIES.?

THE PILOT STATED ?AIRCRAFT DAMAGE: THE PROPELLER SUFFERED MAJOR DAMAGE FROM IMPACTING THE GROUND. THE AIRFRAME SUFFERED MINIMAL DAMAGE. THE LEFT-HAND WINGTIP HAS A SMALL WRINKLE FROM IMPACTING THE GROUND AS WELL WHEN THE AIRCRAFT CAME TO A STOP. TWO ?BOOM HANGARS?, WHICH HELP SUPPORT THE AGRICULTURAL DISPENSING SYSTEM WERE BENT BEYOND REPAIR. THEY CAUSE NO DAMAGE TO THE AIRPLANE OR TO THE CONTROL SYSTEM.?
