Airport (less than 10 km from airport)

When the flight was about 7 miles from the airport and approaching it from the south in dark night conditions, the noncertificated pilot canceled the instrument flight rules (IFR) flight plan. A police officer who was on patrol in the local area reported that he observed a twin-engine airplane come out of the clouds about 500 ft above ground level and then bank left over the town, which was north of the airport. The airplane then turned left and re-entered the clouds. The officer went to the airport to investigate, but he did not see the airplane. He reported that it was dark, but clear, at the airport and that he could see stars; there was snow on the ground. He also observed that the rotating beacon was illuminated but that the pilot-controlled runway lighting was not. The Federal Aviation Administration issued an alert notice, and the wreckage was located about 7 hours later 2 miles north of the airport. The airplane had collided with several trees on downsloping terrain; the debris path was about 290 ft long. Postaccident examination of the airframe and engine revealed no mechanical malfunctions or failures that would have precluded normal operation. The town and airport were located within a sparsely populated area that had limited lighting conditions, which, along with the clouds and 35 percent moon illumination, would have restricted the pilot’s visual references. These conditions likely led to his being geographically disoriented (lost) and his subsequent failure to maintain sufficient altitude to clear terrain. Although the pilot did not possess a valid pilot’s certificate, a review of his logbooks indicated that he had considerable experience flying the airplane, usually while accompanied by another pilot, and that he had flown in both visual and IFR conditions. A previous student pilot medical certificate indicated that the pilot was color blind and listed limitations for flying at night and for using color signals. The pilot had applied for another student pilot certificate 2 months before the accident, but this certificate was deferred pending a medical review.

On December 8, 2012, at 1334 eastern standard time, a Cessna 421C, N297DB, operated by a private individual, was destroyed when it collided with trees and terrain following a loss of control after takeoff from North Palm Beach County Airpark (LNA), Lantana, Florida. The commercial pilot was fatally injured. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight, which was conducted under the provisions of Title 14 Code of Federal Regulations Part 91. The pilot took delivery of the airplane from a maintenance facility that had just completed an annual inspection and repainting of the airplane. According to the owner of the facility, who was a certificated pilot and an airframe and powerplant mechanic, the pilot completed the preflight inspection and the airplane was towed outside. The pilot started the airplane, but then shutdown to resolve an alternator charging light. Afterwards, the pilot stated that he planned to fly to Okeechobee, Florida, complete a few landings, and then continue to Miami. According to the mechanic, the pilot performed a ground run of the airplane for several minutes before taxiing to the approach end of Runway 3 for takeoff. The airplane lifted off about halfway down the runway and climbed at a "normal" rate. The mechanic then observed the airplane suddenly yaw to the left "for a second or two" and the airplane's nose continued to pitch up before rolling left and descending vertically, nose-down, until it disappeared from view. Several witnesses provided similar accounts to a Federal Aviation Administration (FAA) inspector and the local sheriff's department. One witness, a certificated flight instructor said, "The airplane just kept pitching up, and then it looked like a VMC roll."

The twin engine aircraft was engaged in an ambulance flight from La Yesca to the Zapopan Air Base, carrying two soldiers who were injured in a car crash, and one pilot. During the takeoff roll, the airplane encountered strong crosswinds and went out of control. It veered off runway to the right and came to rest in a wooded area. All three occupants were rescued while the aircraft was damaged beyond repair.

The instrument-rated private pilot was executing a non precision instrument approach procedure at night in deteriorating weather conditions. According to GPS track data, the pilot executed the approach as published but descended below the missed approach point's minimum altitude before executing a climbing right turn. This turn was not consistent with the published missed approach procedure. The airplane then began a series of left and right ascending and descending turns to various altitudes. The last few seconds of recorded data indicated that the airplane entered a descending left turn. Two witnesses heard the airplane fly overhead at a low altitude and described the weather as foggy. Reported weather at a nearby airport about 26 minutes before the accident was visibility less than 2 miles in mist and an overcast ceiling of 300 feet. A friend of the pilot flew the same route in a similarly equipped airplane and arrived about 30 minutes before the accident airplane. He said he performed the same approach to the missed approach point but never broke out of the clouds, so he executed a missed approach and diverted to an alternate airport. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. Federal Aviation Administration Flight Training Handbook Advisory Circular 61-21A cautions that pilots are particularly vulnerable to spatial disorientation during periods of low visibility due to conflicts between what they see and what their supporting senses, such as the inner ear and muscle sense, communicate. The accident airplane's maneuvering flightpath, as recorded by the GPS track data, in night instrument meteorological conditions is consistent with the pilot's loss of airplane control due to spatial disorientation.

The four engine aircraft was completing a cargo flight from Pointe-Noire to Brazzaville, carrying one passenger, a crew of six and a load consisting of automobiles and various goods. On final approach to runway 05L in poor weather conditions, the crew descended too low on the glide when the aircraft impacted houses and tree tops and eventually crashed in the district of La Poudrière, about 900 metres short of runway. All 7 occupants were killed as well as 25 people on the ground. Fourteen other people were injured. At the time of the accident, weather conditions were poor with thunderstorm activity, rain falls and limited visibility. MAK stated in February 2013 that they received the FDR from the Congolese authorities but the recorders show mechanical damages as a result of the impact forces.

On November 28, 2012, about 1435 eastern standard time, an experimental amateur-built Comp Air 8 (CA-8), N155JD, operated by a private individual, was substantially damaged during a go-around, while attempting to land at the Merritt Island Airport (COI), Merritt Island, Florida. The certificated commercial pilot sustained serious injuries and a passenger sustained minor injuries. Visual meteorological conditions prevailed and no flight plan was filed for the personal flight that was conducted under the provisions of 14 Code of Federal Regulations Part 91. The pilot reported that he flew from Smithfield, North Carolina, to Marion, South Carolina (MAO), without incident. After refueling, he departed MAO for COI. While en route, approximately 150 miles north of Ormond Beach, Florida, the airplane began to experience a left rolling tendency, which required right aileron control inputs to counteract. He configured the fuel selector to the left fuel tank in an attempt to lighten the wing and compensate for the turning tendency; however, the force required to maintain directional control became greater as the flight progressed. The pilot subsequently entered the traffic pattern at COI for runway 29, a 3,601-foot-long, 75- foot-wide, asphalt runway. While maneuvering in the traffic pattern, full right aileron control was required to maintain straight and level flight, and only a slight relaxing of right aileron control was needed to turn left. The pilot had difficulty compensating for a northwest crosswind, which resulted in the airplane drifting to the southern edge of the runway. He performed a go-around and lined-up on the northern side of the runway 29 approach course for a second landing attempt, which again resulted in a go-around. When the pilot applied engine power, the airplane began to slowly roll to the left despite right aileron and rudder control inputs. He decreased engine power; however, the airplane's left wing struck the ground and the airplane flipped-over. The left wing, propeller, and empennage separated during the impact sequence. The airplane's flight controls were electrically actuated. On site examination of the airplane by a Federal Aviation Administration (FAA) inspector did not reveal any preimpact malfunctions, which would have precluded normal operation. The fuel tanks were compromised during the accident. The airplane's rudder, elevator, and aileron control servos were removed for further examination. According to the FAA inspector, the rudder and elevator control servos functioned normally; however, the aileron control servo sustained impact damage during the accident sequence and could not be tested. The six seat, high-wing, tail-wheel, turboprop airplane, serial number 998205, was constructed primarily of composite material and was equipped with a Walter M601D series, 650 horsepower engine, with an AVIA 3-bladed constant-speed propeller. According to FAA records, the airplane was issued an experimental airworthiness certificate on April 26, 2001. The airplane was purchased from one of the builders, by the commercial pilot, through a corporation, on September 30, 2012. At that time, the airplane had been operated for about 925 total hours and had undergone a condition inspection. The pilot reported about 5,570 hours of total flight experience, which included about 100 hours in the same make and model as the accident airplane. In addition, the pilot had accumulated about 23 hours and 5 hours in make and model, during the 30 and 90 days preceding the accident, respectively. Winds reported at an airport located about 8 miles southeast of the accident site, about the time of the accident, were from 340 degrees at 16 knots.

The single engine aircraft was engaged in a local skydiving mission, carrying one pilot and 9 skydivers. Shortly after take off from runway 31, while climbing to a height of about 80 meters, the engine suffered a power loss. The pilot initiated a left turn to reach the airport when the aircraft rolled to an angle of 60° then stalled and crashed in a snow covered field near a forest, bursting into flames. The aircraft was destroyed by a post impact fire. Nine occupants escaped injured and a passenger was killed.

On the morning of 25 November 2012 at 0902Z the pilot, sole occupant on board the aircraft, took off from FAGC to FATZ. He filed an IFR flight plan to cruise at F110 in controlled airspace. The take-off roll and initial climb from RWY 17 was uneventful and passing FL075 FAGC Tower Controller transferred the aircraft to Johannesburg Approach Control (Approach) on 124.5 MHz. On contact with Approach the pilot was cleared to climb to FL110. On the climb approaching FL090 the aircraft lost power on the left engine, oil pressure dropped and the cylinder head temperature increased. He then advised Approach of the problem and requested to level out at FL090 to attempt to identify the problem. He requested radar vectors from Approach to route direct to FAGC and proceeded to shut down the left engine. The pilot continued routing FAGC using the right engine but was unable to maintain height. He noticed the oil pressure and manifold pressure on the right engine dropping. The pilot also reported seeing fire through the cooling vents of the right engine cowling. The pilot requested distance to FAGC from Approach and was told it is 2.5nm (nautical miles) and the aircraft continued loosing height. An update from Approach seconds later indicated that the aircraft was 1nm from FAGC. The pilot decided to do a wheels up forced landing on an open field when he realized that the aircraft was too low. He landed wheels up in a wings level attitude. The aircraft impacted and skidded across an uneven field and came to a stop 5m from Donovan Street. The pilot disembarked the aircraft and attempted to put out the fire which had started inflight on the right engine but without success. Eventually the right wing and the fuselage were engulfed by fire. Minutes later the FAGC fire department using two vehicles extinguished the fire. The pilot escaped with no injuries and the aircraft was destroyed by the ensuing fire.

Following an uneventful flight from Yakutsk-Magan Airport, crew started the descent to runway 10. On touch down on a snow covered runway, aircraft landed slightly to the left of the centerline. After a course of 350 meters, left main gear hit a snow berm of 20-50 cm high. Aircraft continued to the left, veered off runway and came to rest in snow covered field with its right main gear and right wing severely damaged. All 29 occupants were evacuated safely while the aircraft was damaged beyond repair.

The aircraft was completing a cargo flight from Entebbe, carrying four crew members and a load consisting of foodstuffs. After landing, the aircraft was unable to stop within the remaining distance. It overran, lost its left main gear and came to rest in bushes. While all four occupants escaped uninjured, the aircraft was damaged beyond repair.
