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.

Narrative: Mr. Keen was taxiing, N4476W, from in front of his t-hangar to another section of the t-hangar area, when the brakes failed and could not stop the aircraft. The aircraft rolled off into a ditch. Mr. Keen did try to use differential power to avoid the ditch and finish the turn, but it did not work. He shut down both engines, before the aircraft entered the ditch. To make the turn with the aircraft does require two sharp ninety degree turns. The brake system was checked by inspector king and meyers. No abnormalities were discovered and could not determine why the brakes failed in the turn. Mr. Keen did state that he did not intend to fly the aircraft, but was only moving to another ramp to clear the ramp in front of his t-hangar. Brief explanation of issues involved for each of the nine responsibilities involved: privacy data omitted this was due to heavy use of the brakes during the initial turn and pumping of the brakes several times. The brakes would temporarily stop working. The pilot used poor technique to make a series of tight turns on the small taxiway ways found in the t-hangar area.

As the FAA filed it

NARRATIVE: MR. KEEN WAS TAXIING, N4476W, FROM IN FRONT OF HIS T-HANGAR TO ANOTHER SECTION OF THE T-HANGAR AREA, WHEN THE BRAKES FAILED AND COULD NOT STOP THE AIRCRAFT. THE AIRCRAFT ROLLED OFF INTO A DITCH. MR. KEEN DID TRY TO USE DIFFERENTIAL POWER TO AVOID THE DITCH AND FINISH THE TURN, BUT IT DID NOT WORK. HE SHUT DOWN BOTH ENGINES, BEFORE THE AIRCRAFT ENTERED THE DITCH. TO MAKE THE TURN WITH THE AIRCRAFT DOES REQUIRE TWO SHARP NINETY DEGREE TURNS. THE BRAKE SYSTEM WAS CHECKED BY INSPECTOR KING AND MEYERS. NO ABNORMALITIES WERE DISCOVERED AND COULD NOT DETERMINE WHY THE BRAKES FAILED IN THE TURN. MR. KEEN DID STATE THAT HE DID NOT INTEND TO FLY THE AIRCRAFT, BUT WAS ONLY MOVING TO ANOTHER RAMP TO CLEAR THE RAMP IN FRONT OF HIS T-HANGAR. BRIEF EXPLANATION OF ISSUES INVOLVED FOR EACH OF THE NINE RESPONSIBILITIES INVOLVED: ^PRIVACY DATA OMITTED^ THIS WAS DUE TO HEAVY USE OF THE BRAKES DURING THE INITIAL TURN AND PUMPING OF THE BRAKES SEVERAL TIMES. THE BRAKES WOULD TEMPORARILY STOP WORKING. THE PILOT USED POOR TECHNIQUE TO MAKE A SERIES OF TIGHT TURNS ON THE SMALL TAXIWAY WAYS FOUND IN THE T-HANGAR AREA.
