Analysis

Drg arrival, the acft was vectored to intercept the ILS rwy 27 localizer (LOC) bfr reaching the munci initial apch fix (iaf), which was 21.5 mi fm the rwy. The ATC controller (ctlr) told the plt to maint 4000' until on the LOC, then clrd him for the apch. From the iaf, the min alt on the apch was 3700' until intercepting the ILS glide slope (gs) at the picture rocks NDB (faf). The NDB was 9.4 mi from the arpt; the outer marker (om) was 4.8 mi from the rwy. As the plt contd, he rprtd that his instruments showed he was on the gs at 2700', but that he was still headed inbnd twd the NDB. The ctlr warned that the acft should be at 3700' until reaching the NDB & repeated the altimeter setting. Moments there-after, the ctlr lost contact with the acft. It crashed nr the top of a hill on wooded terrain at an elev of about 2400',aprx 9 mi bfr reaching the NDB. An exam revealed the acft nav equip was properly set. No preimpact malfunction or fail- ure was fnd. The ILS sys was flt checked & fnd to operate normally.
