On June 4, 1984, an unmodified Gates Learjet 23A, N101PP, was being operated by Air Continental, Inc., Elyria, Ohio, on a regularly scheduled cargo flight transporting cancelled bank checks under 14 CFR 135. The flight departed Cleveland-Hopkins International Airport, Ohio, as Night Air 4 at 2200 eastern daylight time. After an uneventful flight, Night Air 4 arrived at Syracuse-Hancock International Airport, New York, at 2245. There was routine ground cargo handling at Syracuse; the airplane was not refueled. Night Air 4 departed Syracuse at 2311, was cleared to climb to 17,000 feet, and was handed off to Boston Air Route Traffic Control Center (Boston Center) at 2314. Boston Center cleared Night Air 4 to its requested altitude of FL290 and the en route portion of the flight was uneventful. At 2332, Night Air 4 was handed off at 16,000 feet during its descent to Bradley International Airport, Windsor Locks, Connecticut Approach Control. Approach control identified the airplane, cleared it for a visual approach to runway 33, and at 2336 gave Night Air 4 a turn to position the airplane on final approach at 10 miles from the airport. At 2338:22, Night Air 4 reported that the airplane was on final approach for runway 33, and at 2338:25 the air traffic control tower operator cleared the flight to land. At 2341:18, the control tower operator reported to approach control that there had been an accident at the airport. Fifteen witnesses, who either heard and/or saw the accident, were interviewed, and with the exception of a few minor points, all of the witnesses described basically the same accident sequence. The airplane was on a normal approach to runway 33 with no apparent abnormalities. When the airplane was about 200 feet over the approach lights, an increase in engine thrust was heard and the airplane halted its rate of descent in what two pilot witnesses thought was an apparent attempt to go-around. Immediately afterward, Night Air 4 began what appeared to be a level turn to the right. As the airplane went through about 90° of turn, the wings of the aircraft were nearly vertical to the ground. The airplane's nose dropped below the horizon and the airplane descended into the ground in a nose low attitude. The witnesses stated that they saw an explosion which was followed by intense ground fire. None of the witnesses reported any significant lateral or vertical changes while the aircraft was on short final or during the 90' right turn prior to its descent into the ground. Many witnesses stated that they saw some lights illuminated on the aircraft but none reported seeing the landing lights, located on the landing gear, or the landing gear in the extended position. Witnesses reported no inflight fire, smoke, or airframe separation before the crash. All three occupants were killed.

The aircraft was found where it had crashed and burned on a rough lava bed. The crash site was about one mile northeast of a road where drug smuggling aircraft had been known to land in the past. There was evidence that cocaine had been removed from the accident site. The wreckage had been camouflaged by placing lava rocks on the shiny pieces of metal. There was evidence that the plane had crashed in a left wing low attitude while in a landing configuration. No preimpact/mechanical part failure or malfunction was found. The elevation of the crash site was about 2,930 feet. The aircraft wreckage was discovered on 6/2/84. The actual time of the accident was not determined. Both occupants were killed.

Zantop ground personnel completed the loading of Flight 931 at 00:40. All cargo was bulk loaded and tied down on the right side of the airplane for the full length of the cargo compartment. Flight 931 departed the gate at Baltimore/Washington International Airport at 01:05 and took off on runway 28 at 01:10. At 01:11:42, Flight 931 contacted Baltimore departure control and was cleared to 13,000 feet. After switching to Washington ARTCC, the flight was cleared further FL220. At 01:32 a no. 2 gyro malfunction made the crew select the no. 1 gyro to drive both approach horizons and the problem appeared resolved. At 01:43:09, Cleveland ARTCC cleared Flight 931 direct to the Dryer VOR. After the turn to the Dryer VOR, the first officer’s approach horizon may have displayed incorrect pitch and roll information. The flightcrew may have received conflicting pitch and roll information from the two approach horizons as they attempted to recover from an unusual attitude. The flightcrew overstressed the airplane in an attempt to recover from the unusual attitude as the aircraft spiralled down. The Electra broke up and falling wreckage damaged some houses; however, most of the wreckage fell in uninhabited, wooded areas.

According to law enforcement officers, the aircraft experienced double engine failure and made a forced landing in unimproved terrain. During the landing rollout the aircraft struck several trees. An intense post crash fire erupted destroying all but one wing tip of the wreckage. Repeated efforts to contact the pilot and operator have been unsuccessful. It is assumed that there were no injuries and no passengers.

The aircraft crashed after takeoff from runway 29 at Williamson County Airport. The pilot stated that she mismanaged the fuel system and that she 'probably took off on fumes.' She further stated that she should have told the company 'I'm too tired to make this flight.' The pilot was slightly injured.

The aircraft skidded off the departure end of the runway collapsing the landing gear in a ditch as it caught on fire. This aircraft was on a ferry flight and had several mechanical problems. Among these was the prop reversers which failed on landing. The anti-ice/de-ice systems failed to work properly which contributed to the need to land short of destination. The copilot reported that she did not check the anti-icing equipment on pre-flight. She was also not qualified to be a copilot on this flight. The airspeed indicators were malfunctioning during landing. The crew members all said that they knew the airspeed was much too high. The copilot said she could not understand how the pilot thought he could land at such a high speed. She also said he called for reverse and applied brakes too late in the rollout.

On the day of departure the pilot had received a 30 minutes familiarization flight upon completion of the superstar conversion. Emphasis was directed to engine gages, fuel flow and counter, and power settings. The flight was flown at 5,500 feet. The pilot then obtained a weather briefing and filed a flight plan. About 15 minutes after departure, while climbing thru FL170, the pilot radioed that he had lost both engines. The aircraft was subsequently observed descending uncontrolled out of the overcast. At about 1,000 feet agl the right aileron separated. The fuel boost pumps were found in the 'off' position. The AFM states that the boost pumps should be on during climb above 10,000 feet. The pilot had been enrolled in an Aerostar transition school the previous month during which a 2-hr combined demonstration/flight evaluation flight was conducted. The instructor pilot recommended further multi-engine training. Both occupants were killed.

The pilot was attempting a takeoff on an airstrip where braking action was considered good during the normal summer season. It was about 3,000 feet in elevation and was snow covered most of the year, as on the day of the accident. The strip accommodated takeoffs to the south only due to grading and obstructions. Frequently, this meant a downwind takeoff. On the day of the accident, there was a 5 knots wind from the north with gusts to 10 knots. The pilot said that nose wheel steering was not effective due to the surface and the rudder was not responsive due to the tailwind. Most pilots used a 25° (right turn) dogleg of the runway at the north end to start their takeoff, especially when tailwinds were present. The accident aircraft went off the runway to the left and collided with a snowbank where it nosed over. All four occupants escaped uninjured.

The aircraft was flown earlier in the day for a sales demonstration. On the return flight, when the landing gear were lowered, the pilot thought he heard a noise emitting from the gear, although cockpit indications were normal. The aircraft landed at Johnny Cake Airport and was refueled for a flight to Bradley Field where it is hangared. The pilot stated he intended to make the 22 miles flight with the gear down as a precaution. He also stated his intention to fly below the overcast because of delays of up to 45 minutes in obtaining IFR clearances. Moments after takeoff the aircraft collided with trees east of the airport. About one mile east of the airport is a north-south ridge. Another pilot, who departed 15-20 mins earlier, reported entering the overcast between 400 and 700 feet agl. Ground witnesses one mile southeast of the airport who heard the crash described the weather as heavy fog and mist. One witness estimated the ceiling as 100 feet agl. The pilot, sole on board, was killed.

The pilot stated the engines lost power as a result of snow ingestion and carburetor icing upon entering clouds. According to the pilot, he entered the clouds at 9,000 feet msl and encountered heavy snow. He remained IMC until approximately 100-300 feet agl when he 'broke out' into VMC flight conditions. After ditching the aircraft, the pilot and passenger swam to shore. The aircraft washed out to sea and was not recovered.
