Cessna 500 Citation

The twin-engine turbojet airplane was attempting to land on a runway with standing water when the accident occurred. Before the landing attempt, the pilot was told that the runway was wet from a recent rain shower. Witnesses reported seeing the airplane on the runway traveling at a high speed and then increase engine power to abort the landing with about 1/4 of the runway remaining. The surviving passenger reported that the runway was "soaked and shiny with water." He stated that the airplane landed hard and fishtailed during the landing roll. During the aborted landing the airplane impacted a jet-blast deflector located off the departure end of the runway. The airplane then proceeded through the airport perimeter fence and impacted a residential structure before coming to a stop. The airplane and residential structure were destroyed during a postaccident fire. An examination of the airframe and engines did not reveal any anomalies associated with a preimpact failure or malfunction. The airplane was not equipped with thrust reversers or an anti-skid braking system. Radar track data analysis indicated that when the airplane was about 1/4 mile from the end of the runway it was approximately 16 knots above its target landing reference speed (Vref) and had a descent rate of 1,150 feet per minute. The runway was 4,875 feet long. The calculated landing distance for a runway with standing water is 4,789 feet.

The right main landing gear collapsed on landing. According to the flight crew, after departure they preceded to Mountain Air Airport, where they performed a "touch-and-go" landing. Upon raising the landing gear following the touch-and-go landing, they got an "unsafe gear" light. The crew stated they cycled the gear back down and got a "three green" normal indication. They cycled the gear back up and again got the "gear unsafe" light. They diverted to Greensboro, North Carolina, and upon landing in Greensboro the airplane's right main landing gear collapsed. After the accident, gear parts from the accident airplane were discovered on the runway at Mountain Air Airport. Metallurgical examination of the landing gear components revealed fractures consistent with overstress separation and there was no evidence of fatigue. Examination of the runway at Mountain Air Airport by an FAA Inspector showed evidence the accident airplane had touched down short of the runway.

The 4,100-hour commercial pilot lost directional control of the single-pilot twin-engine turbojet while taking off from runway 22 (7,602-feet long by 150-feet wide), and impacted the ground about 3,750 feet from the point of departure. Several witnesses reported that the airplane climbed to approximately 150 feet, rolled to the right, descended, and then struck the ground inverted. The weather was day VFR and the wind was reported from 170 degrees at 10 knots. Examination of the wreckage revealed that none of the main-entry door latching pins were in their fully locked position. The airplane's flight controls and engines did not disclose any mechanical discrepancies. The flaps were in the takeoff position and the control lock was unlocked. The pilot had not flown the airplane for over nine months because of extensive maintenance; the accident occurred on its first test flight out of maintenance. Since the pilots flight records were not found, it is unknown how much flight time the pilot had flown in the last nine months. The other airplane that the pilot owned was a Cessna 650, but witnesses stated that the pilot was only qualified as a co-pilot. Most of the maintenance records that were located were not completed; an approval for return-to-service was not found. Another airplane that had declared an emergency was on a 10-mile final when the tower cleared the accident airplane for takeoff, with no delay on the takeoff roll. No additional communication or distress calls were reported from the accident airplane. The airplane was not equipped with either a flight data recorder or a cockpit voice recorder. No anomalies were found on either engine that could have prevented normal engine operation.

On final approach to Charallave-Óscar Machado Zuloaga Airport runway 28, the crew was unable to establish a visual contact with the runway and initiated a go-around procedure. Few minutes later, while on a second attempt to land, the aircraft broke through the cloud base at 800 feet but was not properly lined up with the runway. To avoid a collision with the tower, the crew made a turn to the right when the aircraft crashed in a wooded area, bursting into flames. Both pilots were killed.

The aircraft departed Rome-Ciampino Airport on an ambulance flight to Cagliari, carrying three pilots, three doctors and a cooler containing a heart for a patient. The descent to Cagliari-Elmas Airport was initiated by night under VFR mode. After the crew was cleared to descend to 2,500 feet, ATC reported runway 32 in use and asked the crew to report on short final. About two minutes later, at an altitude of 3,333 feet, the aircraft struck the slope of Mt Su Baccu Malu located 32 km northeast of Cagliari Airport. The aircraft was totally destroyed by impact forces and all six occupants were killed.

The aircraft took off at 1000LT from Barcelona (LEBL) on a private flight to Zurich (LSZH). The flight took place under instrument flight rules. Using radar vectors, EC-HFA was cleared at 1205 LT for an approach on the runway 14 instrument landing system (ILS). In the final approach phase, the aircraft entered a snow shower. The aircraft touched down on the grass about 700 metres before the runway threshold and skidded in a wide right turn in the direction of the threshold of runway 16. The aircraft was badly damaged. The three occupants were unharmed.

Following an uneventful flight from Goiânia-Santa Genoveva Airport, the crew started the descent to Marília Airport by night. Poor weather conditions at destination forced the crew to make a direct approach to runway 03. After landing, the aircraft was unable to stop within the remaining distance, overran, lost its undercarriage and came to rest in bushes 143 metres past the runway end. All seven occupants were rescued, among them four were injured. The aircraft was damaged beyond repair.
