Factual narrative
THE PIC STATED THAT HE HAD TO FLY A FASTER THAN NORMAL APPRCH TO THE OUTER MARKER FOR THE ILS APPRCH AS INSTRUCTED BY APPRCH CONTROL. APPRCH CNTL INDICATED THAT A BOEING 727 WAS NO. 2 FOR THE APPRCH AND THAT THE PIC SHOULD MAINTAIN 230 KTS TILL FURTHER ADVISED. THE PIC STATED THAT HE COMPLIED WITH THE RQST. THE PIC STATED THAT ONCE PAST THE OUTER MARKER HE INITIATED THE SLOW DOWN OF THE ACFT BY RETARDING THROTTLES AND DEPLOYING SPOILERS. THE DISTANCE IN WHICH TO SLOW THE ACFT IS 4.2 MILES FM THE OUTER MARKER. THE PIC STATED THAT HE DISABLED THE GEAR WARNING HORN WHEN HE RETARDED THE THROTTLES AND NEVER RESET THE WARNING HORN FOR THE REMAINDER OF THE APPROACH. THE LANDING CHECK WAS NOT COMPLETED PRIOR TO THE ACFT CONTACTING THE RWY. THE PIC STATED THAT POOR CREW COORDINATION AND THE HIGH SPD DURING THE APPRCH CONTRIBUTED TO THE GEAR UP LNDG.
