Cessna 340

Shortly after takeoff on a check-out flight the aircraft was observed on crosswind leg to descend until impact. There was an extensive post impact fire. Witnesses heard the aircraft make a 'poof' type of noise just as the pilot radioed the control tower and stated that he was experiencing an emergency of unknown nature. The paper air filter element for the left engine exhibited the presence of oil, and the left side of the aircraft had evidence of oil spatter and streaking. Both occupants were killed.

During IFR flight at 12,000 feet both aircraft vacuum pumps failed. Aircraft descended in right turn off radar. Witnesses observed aircraft at low altitude above trees, circle, make steep left turn, climb and descend to ground. The pilot, sole on board, was killed.

Shortly after takeoff from Egelsbach Airport, while climbing, the twin engine aircraft went out of control and crashed in Gräfenhausen. The wreckage was found along a highway and the pilot, sole on board, was killed.

Shortly after takeoff, the aircraft suffered an engine failure. Control was lost and the aircraft crashed, bursting into flames. Both pilots were killed.

The pilot was carrying illegal cargo (marijuana) in N4001Q. During a low high speed pass at night over an intended landing area, the aircraft struck rising terrain. There was approximately 800 lbs of marijuana on the aircraft. The aircraft was destroyed and the pilot, sole on board, was killed.

Pilot requested fuel from fbo but failed to make it clear what type he wanted. The fbo personnel misunderstood the pilot's request and refueled the aircraft with 'Jet-A' instead of aviation grade gasoline. The pilot did not monitor the refueling process and failed to recognize the wrong fuel as stated on fuel receipt. The pilot did not realize the improper fuel on his preflight of the aircraft. The aircraft departed and shortly there after the pilot radioed that he was returning to the airport because of a serious problem. Witnesses near the accident site stated that the aircraft was in a left bank (about 45° bank angle) before impact in a densely wooded area. The aircraft was destroyed and all four occupants were killed.

Prior to departure the pilot had received a weather forecast which indicated that fog could be expected at the destination. Adequate fuel was carried in the aircraft tanks to allow for a considerable period of holding and/or a diversion to another aerodrome if required. After an apparently normal flight of 35 minutes the aircraft arrived in the Goulburn area and the pilot reported his intention to carry out a standard instrument approach. The manoeuvres associated with this procedure do not involve flight over the city of Goulburn, however witnesses observed the aircraft as it circled over the city several times at a relatively low height. It was then seen to roll and descend steeply before striking two houses. A fierce fire broke out which engulfed the aircraft and both residences. The three persons on board the aircraft and a person in one of the houses received fatal injuries. A detailed inspection of the wreckage revealed that the camshaft of the left engine had failed in flight and the pilot had apparently feathered the propeller. The engine was not operating at the time of impact. No other defect or malfunction was discovered which might have contributed to the development of the accident. It was determined that the particular camshaft had failed from fatigue cracking, resulting from defective manufacture. It was considered likely that when the aircraft arrived over Goulburn, shallow fog obscured all or part of the aerodrome. The lights of the city would have been clearly visible and the pilot probably decided to use the city, rather than the nearby radio navigation aid, as a convenient holding point while waiting for conditions at the aerodrome to improve. During a series of left hand orbits, and after advising his intention to conduct an instrument approach, the pilot experienced a complete failure of the left engine. In order to realise the available single-engine performance of the aircraft the pilot had to perform a series of checks and actions which would result in the applicable propeller being feathered; any unnecessary aerodynamic drag being reduced; and an appropriate airspeed being established. It was determined that although the propeller had probably been feathered, the landing gear, which had evidently been lowered previously, had not been raised to reduce drag. In addition, an analysis of radar returns from the aircraft, recorded at Canberra, indicated that the airspeed at which the aircraft was flying shortly before radar contact was lost, was less than the optimum figure. The final manoeuvre described by witnesses was consistent with that which follows a loss of control in twin engine aircraft when power is being supplied by only one engine and the speed is below the minimum required for full control. The reason the pilot did not raise the landing gear and maintain the required minimum control speed could not be established.

The aircraft collided with a hilltop during a missed approach in IMC weather. The aircraft was on an IFR flight plan. The pilot stated visual contact was established at about 2,000 feet msl but ground features were masked in snow. When the pilot did not see the airport at the proper time he commenced a missed approach and the aircraft struck the ground. Investigation revealed that the obs (vor course indicator) was set on 222° instead of 202° for the published inbound heading. The resultant course passed directly over the accident site. The aircraft was not observed on radar because of its low alt. The pilot, sole on board, was seriously injured.

The aircraft disappeared from radar coverage while in cruise flight at 10,000 feet msl near Orangeville, FL. The ATC transcript revealed that the pilot had been inquiring about the weather ahead of him and was cleared to descend to 6,000 feet in order to get below strong headwinds. One minute later he transmitted that he was going to stay at 10,000 feet because he did not have any choice (strong turbulence). His last transmission stated the weather was getting worse. The aircraft has not been located.

The aircrew of a Cessna 340, N5415M, were scheduled for an air taxi check ride with an inspector at Jackson, WY, later in the afternoon. They had planned to takeoff from Rock Springs, WY, practice at few instrument approaches at Rock Springs, then proceed to Jackson. After taking off, they made an NDB approach, made a missed approach, then began an ILS approach. A Beech Bonanza, N1825F, was on a flight from Scottsbluff, NE to Rock Springs. During arrival to Rock Springs, the Bonanza pilot was monitoring the position of a King Air that was ahead of him and also on an approach to the same airport. All three aircraft were using the same frequency and all three were providing reports of their respective positions. At approximately 1103 mdt, witnesses heard N5415M and N1825F collide, then saw the aircraft and pieces of wreckage falling. An investigation revealed the Cessna was inbound toward the outermarker (270° course) and the Bonanza was in level flight, heading approximately 219°. Both aircraft were operating VFR. All six occupants in both aircraft were killed.
