Analysis

While being vectored for an ILS rwy 7 apch, the plt was told to maint 3000' & advised he was flwg a Boeing 727. The min apch alt bfr intercepting the ILS glide slope (g/s) at the final apch fix/outer marker (om) was 1900'. As the acft was apchg the om, the plt was clrd for the apch & was handed off to the twr. After contacting the twr, the plt was told to dscnd as published. At aprx that time, the twr controller (ctlr) & his supervisor discussed N700CM'S alt & proximity to the 727. The ctlr was going to discontinue the apch, but his supvr suggested he wait & see if it would work out. Subsequently, N700CM crashed into trees aprx 5800' short of the rwy while dscndg in a wings lvl attitude. Radar data showed N700CM was well abv the ILS g/s when clrd for the apch. ATC procedures reqd the acft to be blo the g/s bfr being clrd. Also, N700CM was aprx 2.57 mi behind the 727, but stayed well abv the 727'S flt path (& possible wake turbulence) until moments bfr impact. N700CM entered an excessive rate of dscnt bfr going blo the g/s.
