NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

THE AIRCRAFT WAS RADAR VECTORED TO THE FINAL APPROACH FOR AN ILS LANDING. AS THE AIRCRAFT APPROACHED THE FINAL APPROACH FIX THE CONTROLLER CLEARED THE AIRCRAFT FOR THE APPROACH AND INSTRUCTED THE PILOT TO CONTACT THE TOWER. THE PILOT ACKNOWLEDGED THE INSTRUCTION THEN STATED THAT HE WAS STARTING A GO-AROUND. APPROXIMATELY 30 SECONDS LATER THERE WAS AN UNINTELLIGIBLE RADIO TRANSMISSION FROM THE AIRCRAFT. THIS TRANSMISSION WAS FOLLOWED BY A CALL FROM THE PILOT STATING, 'SEVEN NINER THREE IN TROUBLE'. THIS TRANSMISSION WAS FOLLOWED 16 SECONDS LATER BY, 'I HAVE I HAVE AN EMERGENCY BACK HERE'. THE CONTROLLER HAD NOTICED AN ASCENT 400 FEET ABOVE THE ASSIGNED ALTITUDE THEN THE RADAR WENT INTO COAST. A WITNESS IN A BOAT IN THE VICINITY OF THE ACCIDENT OBSERVED THE AIRCRAFT DIVE OUT OF A CLOUD AND COLLIDE WITH THE WATER.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

LOSS OF CONTROL OF THE AIRCRAFT, BY THE PILOT, WHILE EXCUTING A MISSED APPROACH.
