What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pilot detected a low oil pressure indication and decided to make an immediate precautionary landing at Independence, Missouri (3IP), as the airport had just been overflown. During the landing approach, the radios failed and the electrical system was noted as not functioning. A safe landing was accomplished and maintanance personnel were summoned. Interview of the mechanic revealed that the field terminal to the alternator had failed, disabling the alternator. The oil pressure gauge is electrical, not direct reading, and diminishing battery power caused the erroneous low oil pressure indication. Pilot's actions were appropriate for the apparent circumstance indicated by the engine oil pressure instrument. Incident number CE2002IGA0007
