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: airworthiness: crankcase breather tube froze shut, causing depletion of oil supply through ruptured crank seal. AD 64-17-05 required a modification to the breather system to prevent this type occurrence. However, this AD applies only to early model lake aircraft but does not apply to the LA250. On 2-5-94, at 9:30AM CST, a lake LA-250, N613RB, owned and operated by james e. rhude, experienced a complete loss of oil pressure and the resultant loss of engine power necessitated an off airport landing in a snow covered field. The aircraft sustained minor damage. The private pilot and one passenger were uninjured. VMC conditions prevailed. And an IFR flight plan was filed. The flight originated from hibbing, MN at 0822.
