Background
The private pilot had obtained her instrument rating three months prior to the accident. The first instrument landing system (ILS) approach into the airport resulted in a missed approach.
Flight Sequence
During a subsequent approach, just prior to reaching the outer marker, the pilot was given a frequency change. She replied that she was in serious trouble. Shortly thereafter, the aircraft disappeared from radar, and no further radio transmissions were made by the pilot.
Witness Observations
Witnesses reported that the aircraft descended out of the base of the clouds in a nose-down attitude with a steep left bank.
Aircraft Examination
Examination of the aircraft revealed no mechanical or instrumentation malfunctions.
