What happened
Following a missed approach at an airport located approximately 10 miles southeast of an alternate airport due to adverse weather, the pilot diverted to the alternate field. The pilot was cleared for an ILS Runway 18 approach. After passing the final approach fix, the pilot received clearance to contact the airport's advisory service.
While continuing the inbound flight, the aircraft struck a quarry wall. The collision occurred approximately 2 miles north of the airport and 1/4 mile east of the localizer centerline. At the time of the accident, the elevation at the top of the quarry wall was 480' MSL, while the airport elevation was 474' MSL. The decision height for the approach was established at 674' MSL.
The investigation
An examination of the aircraft revealed no preimpact failure. However, the aircraft sustained extensive damage resulting from the impact and a subsequent ground fire.
