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.

(.19) On may 25, 2002, at 1300 central daylight time, an aero commander 500-S twin-engine airplane, N98TT, was substantially damaged during landing roll at the La Porte Municipal Airport near La Porte, Texas.

Visual meteorological conditions prevailed, and flight plan was not filed for the 14 code of federal regulations part 91 business flight. The flight originated from gatesville, Texas, at 1125. Preliminary information indicates that after touchdown on runway 14, brake pressure was lost, and the airplane ran off the end of the runway and went through a fence and ditch before coming to a stop. The FAA inspector, who responded to the accident site, reported that the airplane's nose and nose landing gear were damaged, and the left wing sustained substantial damage. The inspector further reported that a hydraulic line had failed. (-23) substantial damage to the aircraft, but no injuries, when this shrike commander landed and ran off the end of the 3,981 foot long runway and imp acted a fence and a 2 foot deep ditch. The pilot reported that he had extended landing gear and full flaps in a normal manner, but he discovered a total hydraulic system failure after touch-down on runway 12. During the landing rollout the pilot reported a complete loss of nosewheel steering and a complete loss of wheel brakes. Post accident examination of the aircraft showed the hydraulic reservoir was empty and the aft section of the right engine nacelle, right wing root area, and right empennage were covered in hydraulic fluid. An IA mechanic who examined the wreckage on the day of the accident reported that this aircraft had a maintenance history of a previous failure of a hydraulic line where the line rubbed on the phenolic block that supported the hydraulic line.
