Beechcraft 90 King Air

The airplane was fueled with 140 gallons of fuel before the second of three flight segments. The pilot reported that, while en route on the third segment, a fuel crossfeed light illuminated. He reset the indicator and decided to land the airplane to troubleshoot. He requested to divert to the nearest airport, which was directly beneath the airplane. Subsequently, the right engine lost power, and the autofeather system feathered the right engine propeller. He reduced power on the left engine, lowered the nose, and extended the landing gear while entering the traffic pattern. The pilot indicated that, after the landing gear was extended, the electrical system "failed," and shortly after, the left engine would not respond to power lever inputs. As the flight was on a base leg approach, the airplane was below the intended flightpath to reach the runway. The pilot stated that he pulled "gently on the control wheel"; however, the airplane impacted an embankment and came to rest on airport property, which resulted in substantial damage to both wings and the fuselage. Postaccident examination of the engines and airframe revealed no evidence of mechanical malfunctions or abnormalities that would have precluded normal operation. Signatures on the left propeller indicated that the engine was likely producing power at the time of impact; however, actual power settings could not be conclusively determined. Signatures on the right propeller indicated that little or no power was being produced. The quantity of fuel in the airplane's fuel system, as well as the configuration of the fuel system at the time of the accident, could not be determined based on the available evidence. Although the position of the master switch (which includes the battery, generator 1, and generator 2) was found in the OFF position, the airplane had been operating for about 30 minutes when the electrical power was lost; thus, it is likely that the airplane had been operating on battery power throughout the flight. This could have been the result of the pilot's failure to activate, or his inadvertent deactivation of, the generator 1 and 2 switch. If the flight were operating on battery power, it would explain what the pilot described as an electrical system failure after the landing gear extension due to the exhaustion of the airplane's battery. The postaccident examination of the left engine and propeller revealed that the engine was likely producing some power at the time of impact, and an explanation for why the engine reportedly did not respond to the pilot's throttle movements could not be determined. Additionally, given the available evidence, the reason for the loss of power to the right engine could not be determined.

The twin engine airplane departed Belo Horizonte-Pampulha-Carlos Drummond de Andrade Airport on a flight to Setubinha-Fazenda Sequóia Airfield, carrying one employee of the company and two pilots. Prior to takeoff, the captain informed the copilot he wanted to perform an 'American' takeoff with full engine power followed by a steep climb. After liftoff, the crew raised the landing gear then continued over the runway at low height until the end of the terrain to reach a maximum speed, then initiated a steep climb at 90°. The aircraft reached the altitude of 1,700 feet in 15 seconds then stalled and entered an uncontrolled descent. It dove into the ground and crashed in a vertical attitude into a houses located in a residential area some 800 metres from the airport. The aircraft was destroyed by impact forces and a post crash fire and all three occupants were killed. One people on the ground was slightly injured.

The twin engine airplane departed Laguna del Sauce Airport on a charter flight to San Fernando Airport near Buenos Aires, carrying eight passengers and two pilots. Shortly after a night takeoff from Laguna del Sauce Airport runway 01, the aircraft entered a controlled descent and crashed in shallow water some 2 km northwest of the airport, bursting into flames. The aircraft was destroyed by a post crash fire and all 10 occupants were killed.

According to the pilot's written statement he departed runway 05 and the airplane veered "sharply" to the right. The pilot assumed a failure of the right engine and turned to initiate a landing on runway 23. Seconds after the airplane touched down it began to veer to the left. The pilot applied power to the left engine and right rudder, but the airplane departed the left side of the runway, the right main and nose landing gear collapsed and the airplane came to rest resulting in substantial damage to the right wing. The pilot reported that he had failed to configure the rudder trim prior to takeoff and that there were no preimpact mechanical malfunctions or anomalies that would have precluded normal operation.

En route from Anaco to Santa Bárbara del Zulia, the twin engine aircraft crashed in unknown circumstances by a wooded area located near Casigua El Cubo. The aircraft was destroyed by a post crash fire and all three occupants were killed. It is believed that the aircraft was engaged in an illegal contraband flight.

On June 25, 2014, about 0750 central daylight time, a Raytheon Aircraft Company C90A, N800MK, was substantially damaged following a runway excursion during an attempted go-around at Houston, Mississippi (M44). The commercial-rated pilot, co-pilot, and two passengers were not injured, while one passenger received minor injuries. The airplane was
operated by BECS, LLC under the provisions of 14 CFR Part 91, and an instrument flight rules flight plan was filed. Day, visual meteorological conditions prevailed for corporate flight that originated at Memphis, Tennessee (MEM). According to the pilot, who was seated in the left, cockpit seat, he was at the controls and was performing a visual approach to runway 21. Just prior to touchdown, while at 90 knots and with approach flaps extended, the right wing "rose severely and tried to put the airplane into a severe left bank." He recalled that the co-pilot called "wind shear" and "go around." As he applied power, the airplane rolled left again, so he retarded the throttles and allowed the airplane to settle into the grass on the left side of runway 21. The airplane struck a ditch, spun around, and came to rest in the grass, upright. A post-crash fire ensued in the left engine area. The pilot and passengers exited the airplane using the main entry door. The pilot reported no mechanical anomalies with the airplane prior to the accident. The co-pilot reported the following. As they turned onto final, he noticed that the wind "picked up" a little by the wind sock. The final approach was stable, and as the pilot began to flare, he noticed the vertical speed indicator "pegged out." The airplane encountered an unexpected wind shear just above the runway. He called out for a go around. The pilot was doing everything he could to maintain control of the airplane. It was a "jarring" effect when they hit the shear. It felt like the wind was trying to lift the tail and cartwheel them over. He felt that the pilot did a good job of keeping the airplane from flipping over. In his 30,000-plus hours flying airplanes, he has never experienced anything quite like what they experienced with this shear. He has instructed on the King Air and does not feel that the pilot could have done anything different to avoid the accident.
