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.

Prior to landing the landing gear was extended. The pilot stated that on checking the brake pedals, the brakes felt normal. Upon touchdown at stl on rwy 30R, N234LT wheel brakes were applied at approximately 100 knots during rollout. The right brake pedal lost pressure, and pedal pumping continued to lose pressure. Eventually minimal braking action was noted on the right brake. Left brake was applied and felt normal braking. The aircraft was allowed to roll out the length of the runway to reduce speed and stop.
