An aircraft on an ILS approach was cleared for landing but initiated a go-around. The pilot then declared an emergency, and the aircraft was observed diving from a cloud into water. Radar showed an altitude deviation before losing contact.

Incident Sequence

The aircraft was under radar vectoring to final approach for an ILS landing. As it neared the final approach fix, the air traffic controller cleared the aircraft for the approach and instructed the pilot to contact the tower. The pilot acknowledged this instruction and then stated that he was commencing a go-around. Approximately 30 seconds later, an unintelligible radio transmission was received from the aircraft. This was followed by a transmission in which the pilot said, "seven niner three in trouble." Another transmission came 16 seconds later: "I have I have an emergency back here."

Controller Observations

The controller noticed that the aircraft had ascended to 400 feet above its assigned altitude. Subsequently, the radar track entered coast mode, indicating a loss of radar contact.

Witness Account

A witness aboard a boat near the accident site observed the aircraft emerge from a cloud in a dive and collide with the water.
