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.

Southwest airlines flight #1087, a Boeing B-737-3H4 aircraft, N378SW, departed Kansas City International (mci) airport on March 23, 1999 at 1:35 pm. During climb, the flight crew was notified that there was an oil smell, with a haze vapor layer build-up, in the aft cabin of the aircraft. The flight crew turned off the casper and recirculation fan which resulted in the haz dissipating. As a precaution, the flight crew returned the aircraft to mci and landed without further incident. Contract aircraft maintenance (cam) mechanic discovered fresh oil from the air cycle machine (acm) discharged on to the tip of the bag cone of the right water separator coalescer bag assembly. The right pack was placed as inoperative on MEL 21-1. The aircraft was returned to service at mci to depart for Indiana at 3:55PM. On March 25, 1999, the right water separator coalescer bag was removed and replaced with the acm serviced with oil. System operational check was uneventful. This incident number CE99IAC0040 is closed.
