Pilot began takeoff on a 5,200 feet dirt runway (upslope to the south, elevation 4,775 feet) with wind from the south at 18-20 knots, density altitude about 7,250 feet. Witnesses observed the aircraft taking off, with the landing gear retracting as it passed their position. Soon thereafter, the pilot transmitted he had 'a problem.' Aircraft was then seen about 200-300 feet agl in right turn, which progressed into a dive. Aircraft impacted in flat attitude 1/2 mile south of runway 17. Passenger video tapes revealed props went out of sync about 6 seconds after takeoff. About 15 seconds later, right prop slowed until blades could be seen turning. Video showed one engine fuel flow at about 90 gph, other engine at minimum setting (about 3 psi), 5° increase in pitch attitude. Exam revealed right engine driven fuel pump drive coupling was scored and only partially engaged. SB ME88-3 complied with; auxiliary fuel pump switches found in low position. Right propeller blades found at fine pitch, lacking rotational damage. Landing gear found up, but unlocked; flaps extended 15°. Emergency procedure training did not replicate high density altitude and max gross weight performance. All 10 occupants were killed.

Witnesses observed the airplane on a 'normal' final approach, then saw it drop 'low and slow, retract the gear and roll to the left into the trees.' Examination of the engines revealed that the left engine failed because of a fatigue failure of a compressor turbine blade. Examination of the right engine revealed no evidence of malfunction that would have prevented the use of full power. The aircrew was experienced and well trained. The radar data confirmed a drop in airspeed just before the airplane contacted the trees. All four occupants were killed.

The crew discussed touch-and-go landings as they walked out to board. The captain occupied the right seat to allow the copilot to fly the short repositioning flight from the left. The airplane lifted off prematurely and remained in ground effect. Roll attitude vacillated slightly before onset of a rapid right roll to inverted at ground impact. The engines continued to run after impact; both were selected to high power. No material or mechanical discrepancy was found which diminished power or aircraft control. Both occupants were killed.

This was the first day on duty in the southern region operation for both pilots. In addition, they had never flown together. During the flight, the flight crew lost awareness of their airplane's position, erroneously believed that the flight was receiving radar services from ATC, and commenced the approach from an excessive altitude and at a cruise airspeed without accomplishing the published procedure specified on the approach chart. The crew believed that the airplane was south of the airport, and turned toward the north to execute the ILS runway 05 approach. In actuality, the airplane had intercepted the back course localizer signal, and the airplane continued a controlled descent until it impacted terrain. The captain and two passengers were killed while the copilot and two other passengers were seriously injured.

The crew was completing a local training flight at Pope AFB. Apparently following a wrong approach configuration, the aircraft landed too far down the runway and was unable to stop within the remaining distance. It overran, lost its undercarriage and came to rest, broken in two. All 14 occupants were injured.

The twin engine aircraft was completing a liaison flight from China Lake on behalf of the US Navy, carrying seven US Navy personnels and two pilots. On final approach in good weather conditions, the aircraft struck the ground in a relative flat attitude about 800 metres short of runway 22, slid for about 200 metres and came to rest. All seven passengers were seriously injured and both crew members (Lt David W. Garnett and Aean Lorenzo Rodriguez) were killed.

The instrument rated pilot was en route to his granddaughter's graduation exercises scheduled for the following day. He had received two preflight weather briefings from flight service and he was advised that marginal VFR conditions existed en route, and instrument meteorological conditions at his destination, and that VFRflight was not recommended. A witness who was below the mountain said he heard a low flying aircraft overhead. He stated that he caught a glimpse of the airplane and said it was 'well below the crest of the mountain' heading south. The weather as reported by the witness was about 200 overcast and visibility below 1 mile in fog. He also mentioned that the clouds had obscured the mountain. Shortly thereafter, he heard what was later determined to be the collision. Search personnel located the burning wreckage on top of Mitchells mountain 50 miles north of Charlottesville. Both occupants were killed.

The airplane became missing while on an IFR flight in instrument conditions from Yakutat, Alaska to Anchorage, Alaska. There was not further radio communication with the airplane after the pilot reported level at his assigned altitude of 12,000 feet msl. After listening to FAA air traffic control tapes of communications with the pilot, his wife stated that several minutes after the point which the FAA said was the last transmission from the pilot, she heard her husband say something about '6,000' and 'icing conditions'. An enhancement examination of the tapes by the FBI laboratory failed to confirm this information. Aircraft damage and occupant injuries are presumed.

The Piper Navajo had not flown for about 9 months. During preparation for flight the pilot discovered that the battery was dead. The battery was removed for charging by the fixed base operator, the battery box was cleaned and painted. The operator advised that the battery was over 3 years old plus the 9 months of non use rendered the battery non reliable and recommended that it be replaced. The pilot choose not to change the battery. The pilot requested that the main tanks be topped. The pilot flew the airplane for a short time. The next day (day of the accident) the pilot, while preflighting the airplane, discovered that the battery was again dead so he requested an external power cart for starting. About an hour into the cross country flight the pilot stated that both engines quit while on the aux tanks. He stated that he had no electrical power for fuel boost pumps or starters. The airplane collided with electrical power lines during the emergency landing attempt in an alfalfa field.

The four engine aircraft departed Pope AFB on a training flight with nine crew members on board. In unknown circumstances, the airplane went out of control and crashed in the Blewett Falls Lake, about 80 km southwest of Pope AFB. All nine occupants were killed.
