Background
The airport is situated adjacent to Norton Air Force Base (AFB). Weather conditions at the time of the accident consisted of a dark, moonless night with 1 mile visibility in fog and haze. The pilot had minimal total night flying experience, and few ground reference lights were present in the area.
Flight Path
Radar data recorded the flight's progress. The pilot completed an Instrument Landing System (ILS) approach to Norton AFB, descending to a low approach, and subsequently received a Special VFR clearance to proceed to Redlands Airport. The circling minimum descent altitude (MDA) for Norton is 1,700 feet above mean sea level (MSL). Norton AFB elevation is 1,100 feet MSL, while Redlands Airport elevation is 1,572 feet MSL. Notably, the circling MDA for Norton is 138 feet above Redlands Airport elevation.
Radar track indicated the flight descended to 1,800 feet on the ILS, after which the Mode C altitude varied between 1,700 and 1,600 feet. The last radar return placed the aircraft approximately 1 mile from Redlands Airport at an altitude of 1,600 feet MSL.
Witness Account
A witness on the airport observed the aircraft fly over Runway 8 in a south-to-north direction, describing it as "low and fast." The witness heard sounds of the crash immediately thereafter.
Accident Scene
