Circumstances:
The flight was cleared for a night ILS approach and advised that tower at destination had closed. Tower had reported at closing that fog was forming and the flight was advised of the fog. The aircraft was located on a remote part of the airport the next morning. The ELT had activated but the signal was weak due to crash damage. Passenger said they never saw runway lights, only taxi lights, and that pilot attempted to perform a go-around. Gear was retracted and aircraft hit level grassy area in a near level attitude. The pilot was not wearing a shoulder harness. The pax crouched in the aisle next to the pilot, helping him find the runway, not wearing restraining belts. No published approach plate for ILS procedure for that runway was found in aircraft. Toxicological report revealed pilot had 3 mcg/ml dextromethorphan, an ingredient found in over counter cold remedies. According to report, levels of that substance in blood greater than 0.1 mcg/ml was sufficient to cause drowsiness.
