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.

ON AN APPROACH TO LAND AT THE DESTINATION, THE SECOND-IN-COMMAND (SIC) WAS FLYING THE AIRPLANE. THE PLANE TOUCHED DOWN WITH THE LANDING GEAR RETRACTED, & THE PROPELLER BLADES CONTACTED THE RUNWAY. THE SIC INITIATED A GO-AROUND (ABORTED LANDING). WITNESSES SAW THE AIRPLANE IN A STEEP LEFT BANK JUST BEFORE IMPACT IN A RIVER NEXT TO THE AIRPORT. PROPELLER STRIKES ON THE RUNWAY EXTENDED 380', INDICATING A TOUCHDOWN SPEED OF 96 KTS. THE LAST PROPELLER STRIKES ON THE RIGHT SIDE INDICATED A SPEED OF 86 KTS. THE LAST STRIKES ON THE LEFT SIDE INDICATED A SLOWING PROPELLER. PUBLISHED VMC FOR THE AIRPLANE WAS 94 KTS. THE CVR TAPE REVEALED THE CREW COMPLETED A DESCENT ARRIVAL CHECK, PERFORMED AN INCOMPLETE APPROACH BRIEFING, & DID NOT PERFORM A BEFORE LANDING CHECK. THE CVR REVEALED NO SOUND OF A GEAR WARNING HORN. COMPANY PERSONNEL STATED THAT THE CIRCUIT BREAKER FOR THE WARNING HORN HAD BEEN FOUND PULLED AT THE COMPLETION OF PREVIOUS FLIGHTS BY OTHER CREW; THIS WAS TO PREVENT A WARNING HORN FROM SOUNDING DURING A HIGH RATE OF DESCENT.

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

FAILURE OF THE COPILOT (SECOND-IN-COMMAND) TO FOLLOW THE CHECKLIST, ASSURE THE GEAR WAS EXTENDED FOR LANDING AND ATTAIN OR MAINTAIN ADEQUATE AIRSPEED (VMC); AND FAILURE OF THE PILOT-IN-COMMAND (PIC) TO PROPERLY SUPERVISE THE FLIGHT AND TAKE SUFFICIENT REMEDIAL ACTION.
