The accident was attributed to fuel exhaustion caused by the pilot's failure to refuel the aircraft during an earlier intermediate stop; a factor was the pilot's inadvertent disorientation. : A Piper PA-32, registration number N8355L, was on approach when propeller RPM suddenly increased and engine instruments indicated zero oil pressure. The aircraft lost power and was substantially damaged during the subsequent off-airport forced landing; one pilot suffered serious injuries, while a second pilot and two passengers suffered minor injuries. The accident was attributed to "the improper installation of the oil filter bypass valve by an unknown person, which resulted in the loss of engine oil and subsequent loss of total power during a normal descent. A contributing factor to the accident was the lack of suitable terrain for the forced landing." : The owner-pilot and a flight instructor in a Eurocopter AS350 Écureuil, registration number N747CH, lost yaw control during low-altitude practice maneuvers with the hydraulic assist for the flight controls switched off. The aircraft crashed, rolled onto its side, and caught fire, and all three occupants suffered
