Cessna 421B Golden Eagle II

According to the pilot, during the takeoff roll from the 5,000-ft-long runway, after reaching an airspeed of 90 knots, the airplane’s acceleration slowed. The airplane reached a maximum airspeed of about 92 knots, which was below the planned rotation speed of 100 knots. The pilot elected to abort the takeoff with about 1,500 ft of remaining runway. He reduced the power to idle and initiated maximum braking. The pilot stated that he did not sense the airplane slowing down but observed tire marks on the runway postaccident that were consistent with braking. The airplane continued off the end of the runway and collided with a fence before coming to a stop. All of the occupants exited the airplane safely, and a post-crash fire ensued. Examination of the runway revealed tire skid marks that began 1,200 ft from the runway end and continued into the grass leading to the airplane. An examination of the airplane revealed that the entire cockpit and cabin areas were destroyed by fire. The engines did not display evidence of a catastrophic failure but were otherwise unable to be examined in more detail due to the degree of fire damage. The parking brake control was found in the off position. All hydraulic brake lines were destroyed by fire, and the main landing gear sustained fire and impact damage. Although the tire marks on the runway indicated that some braking action took place, the extensive fire damage precluded a detailed examination of the braking system, and there was insufficient evidence to determine the reason for the runway excursion.

The pilot reported that, during the initial climbout, about 1,000 ft above ground level, one of the engines stopped producing power. He confirmed that all engine controls were full forward and the main fuel tanks were selected. Immediately thereafter, the remaining engine began to surge, then stopped producing power. He established best glide speed and looked for an area to perform a forced landing. The airplane crashed into a solid waste disposal facility, about 2.3 nautical miles northwest of the departure airport. First responders arrived immediately after the accident and found only a trace amount of fuel within the confines of the accident site or in the fuel tanks. The only postaccident fire was centered on a small, localized area near the right engine turbocharger. Both main fuel tanks were empty, and the auxiliary bladder tanks were ruptured by impact forces. Examination of both engines revealed no evidence of a pre accident malfunction or anomaly. A surveillance video showed no evidence of smoke or mist training the airplane seconds prior to impact. The pilot reported that he departed the airport with 112 gallons of fuel on board. The pilot did not provide evidence of the latest refueling when requested by investigators. The available evidence is consistent with a total loss of engine power to both engines due to fuel exhaustion.

The pilot departed on a short cross-country flight in the twin-engine airplane. Instrument meteorological conditions (IMC) were present at the time. While en route at an altitude of 3,000 ft mean sea level, the pilot reported that the airplane was "picking up icing" and that he needed to "pick up speed." The controller then cleared the pilot to descend, then to climb, in order to exit the icing conditions; shortly thereafter, the controller issued a low altitude alert. The pilot indicated that he was climbing; radar and radio contact with the airplane were lost shortly thereafter. The airplane impacted a field about 7 miles short of the destination airport. Examination of the airplane was limited due to the fragmentation of the wreckage; however, no pre-impact anomalies were noted during the airframe and engine examinations. Extensive damage to the pitot static and deicing systems precluded functional testing of the two systems. A review of data recorded from onboard avionics units indicated that, about the time the pilot reported to the controller that the airplane was accumulating ice, the airplane's indicated airspeed had begun to diverge from its ground speed as calculated by position data. However, several minutes later, the indicated airspeed was zero while the ground speed remained fairly constant. It is likely that this airspeed indication was the result of icing of the airplane's pitot probe. During the final 2 minutes of flight, the airplane was in a left turn and the pilot received several "SINK RATE" and "PULL UP PULL UP" annunciations as the airplane conducted a series of climbs and descents during which its ground speed (and likely, airspeed) reached and/or exceeded the airplane's maneuvering and maximum structural cruising speeds. It is likely that the pilot became distracted by the erroneous airspeed indication due to icing of the pitot probe and subsequently lost control while maneuvering.

On 5th June, 2018 at approximately 3:45pm local, (Eastern Daylight Time) , a Cessna 421B aircraft crashed in dense bushes shortly after departure from Runway 27 at Rocksound Int’l Airport, Rock Sound, Eleuthera, Bahamas. The crash site was located approximately 2,503 feet / .41 nautical mile (nm) north of the threshold of Runway 09 and 8,588 feet / 1.42 nm from threshold of runway 27. The pilot and 2 passengers were killed and the aircraft was destroyed by impact forces and a post-crash fire. The aircraft made initial contact with trees before making contact with the ground and other trees in dense bushes. The aircraft descended right wing first, in an approximately 40 degree nose-down angle. A crater approximately 12 inches deep and 10 feet long by 5 feet wide was created when the aircraft hit the ground, subsequently crossing a dirt road, before coming to rest partially in an upward incline in trees. The nose of the aircraft came to rest on a heading of 355° degrees. The fuselage of the aircraft was located at Latitudes 24° 53’ 50”N and Longitude 076° 11’33”W. A fire ensued after the crash.

The twin engine airplane departed Příbram Airport Runway 06 at 0705LT on a charter flight to Gdansk, carrying one passenger and one pilot. About 30 minutes into the flight, while cruising at an altitude of 14,100 feet, the pilot was cleared to climb to FL180 when he declared an emergency and reported the failure of both engines. The aircraft entered an uncontrolled descent and crashed in a wooded area located 1,5 km northeast of Noviny pod Ralskem, bursting into flames. The aircraft was destroyed by impact forces and a post crash fire and both occupants were killed.

The 69-year-old commercial pilot was making a personal cross-country flight in the newly purchased airplane. When the airplane was on final approach to the destination airport in night visual meteorological conditions, airport surveillance video showed it pitch up and roll to the right. The airplane then descended in a nose-down attitude to impact in a ravine on the right side of the runway. During the descent over the ravine the right wing came in contact with a powerline that briefly cut power to the airport. Postaccident examination of the airframe, engines, and their components revealed no evidence of mechanical anomalies or malfunctions that would have precluded normal operation. The pilot's toxicology findings identified five different impairing medications: clonazepam, temazepam, hydrocodone, nortriptyline, and diphenhydramine. Although the results were from cavity blood and may not accurately reflect antemortem levels, the hydrocodone, temazepam, and diphenhydramine levels were high enough to likely have had some psychoactive effects. While the exact effects of these drugs in combination are not known, it is likely that the pilot was impaired to some degree by his use of this combination of medications, which likely contributed to his failure to maintain control of the airplane.
