Dassault Falcon 10 | Bureau of Aircraft Accidents Archives

As the aircraft was climbing thru 19,000 feet at night, the #2 generator (gen) light came on. The flight crew noted there was no output from the #2 gen and it would not reset. They then checked the #1 gen voltage and noted it was 14 to 15 volts. The crew reduced the electrical load; however, about 5 minutes later, the batteries became discharged and there was a total loss of electrical power. Using a flashlight, the crew diverted to the Chester County Airport which had a 4,600 feet runway. The gear was extended with the emergency system. The elevator trim was inoperative, so both pilots applied back pressure on the yoke to overcome the nose down tendency. After landing about 1/4 of the way down the runway, the crew tried to use the thrust reversers, but the reversers were inoperative. Subsequently, the aircraft continued off the side and beyond the end of the runway, hit a wooden beam and a snowbank, then came to rest in a ditch. An investigation revealed a shaft failure of the #2 gen (starter/gen) and worn brushes in the #1 gen. With total electrical failure, the following were also inoperative: wing flaps, anti-skid, capt's airspeed indicator and altimeter, nose wheel steering, cockpit lighting.

Circumstances:

The Falcon 10 touched down long and fast on a wet runway, experienced hydroplaning and went off the end of the runway, struck a drainage ditch and collapsed the landing gear. The nose gear came back and bent the throttle quadrant bracket, pulled the fuel controls to 90% power. This pushed the aircraft on its belly another 1,000-1,600 feet until it came to a stop on a hillside. Both pilots were uninjured.

Probable cause:

Occurrence #1: on ground/water encounter with terrain/water
Phase of operation: landing - roll
Findings
1. (c) in-flight planning/decision - improper - pilot in command
2. (c) planned approach - improper - pilot in command
3. (c) proper touchdown point - exceeded - pilot in command
4. (c) airspeed - excessive - pilot in command
----------
Occurrence #2: complete gear collapsed
Phase of operation: landing - roll
Findings

Circumstances:

The airplane was unable to takeoff from Chicago-Merrill C. Meigs Airport runway 18, overran and crashed into Lake Michigan. A pilot and a passenger were killed while four other occupants were seriously injured. The aircraft came to rest in 25 feet of water about 300 feet past the runway end.

Probable cause:

The flightcrew's failure to release the parking brake before the takeoff roll was started, which resulted in significant wheel/brake drag and a nosedown pitching moment that inhibited the aircraft's capability to effect a normal acceleration and rotation for takeoff. Contributing to the accident was the lack of adequate company checklist procedures to insure the timely release of the parking brakes.

Circumstances:

The crew (a pilot and a flight engineer) were engaged in a test flight on this first Dassault Falcon 10 prototype of the French manufacturer Avions Marcel Dassault (Dassault Aviation). While cruising at an altitude of 15,000 feet and a speed of 360 knots, control was lost. The airplane entered a dive and crashed in an open field located in Loreux, about 8 km northeast of Romorantin-Lanthenay. The aircraft was destroyed and both occupants were killed.
Crew:
Alain Tretout, pilot,
Jacques Ladeux, flight engineer.

Probable cause:

It is believed that the tail separated in flight following an excessive pressure on the vertical stab while cruising at high speed.
