Flight

The single engine airplane departed Arusha Airport on a charter flight to the Serengeti National Park, carrying 10 tourists and one pilot. While flying in marginal weather conditions, the aircraft impacted hilly terrain near Empakaai Camp and was destroyed upon impact. All 11 occupants were killed.

The twin engine aircraft departed Contamana Airport at 1128LT on a charter flight to Pucallpa, carrying 11 passengers and two pilots. Few minutes after takeoff, while climbing to an altitude of 4,500 feet, the right engine lost power and failed. The crerw decided to return to Contamana but was able to transfer fuel from the left tank to the right tank to restart the right engine. Decision was taken to continue to Pucallpa at an altitude of 13,500 feet. At a distance of 42 km from Pucallpa, the crew started the descent when the right engine failed again, followed shortly later by the left engine. The captain declared an emergency and attempted an emergency landing when the aircraft crashed in a wooded area. All 13 occupants were injured and the aircraft was destroyed.

The twin engine aircraft departed Dundo Airport at 1658LT on an ambulance flight to Luanda, carrying three doctors, one patient from South Africa and three crew members. About 15 minutes into the flight, the crew reported engine problems when one of them caught fire shortly later. The airplane went out of control and crashed in an open field located near Cuilo, about 170 km southwest of Dundo. All seven occupants were killed.

The twine engine airplane departed Almaty Airport at 1835LT on an ambulance flight to Shymkent, carrying two doctors, two pilots and one flight mechanic. About 22 minutes into the flight, while cruising by night and poor weather conditions, the crew encountered an unexpected situation and was forced to shut down the right engine. Shortly later, the aircraft crashed near the village of Mezhdurechenskoye, some 28 km northwest of Almaty Airport, bursting into flames. The aircraft was totally destroyed by impact forces and a post crash fire and all five occupants were killed.

The commercial pilot and passenger departed on a local flight in the twin-engine airplane. According to a witness, the pilot took off from the private grass runway and departed the area for about 10 minutes. The airplane then returned to the airport, where the pilot performed a low pass over the runway and entered a steep climb followed by a roll. The airplane entered a nose-low descent, then briefly leveled off in an upright attitude before disappearing behind trees and subsequently impacting terrain. The pilot's toxicology testing was positive for ethanol with 0.185 gm/dl and 0.210 gm/dl in urine and cavity blood samples, respectively. The effects of ethanol are generally well understood; it significantly impairs pilot performance, even at very low levels. Federal Aviation Administration regulations prohibit any person from acting or attempting to act as a crewmember of a civil aircraft while having 0.040 gm/dl or more ethanol in the blood. While the identified ethanol may have come from sources other than ingestion, such as postmortem production, the possibility that the source of some of the ethanol was from ingestion and that pilot was impaired by the effects of ethanol during the accident flight could not be ruled out. Toxicology also identified a significant amount of diphenhydramine in cavity blood (0.122 µg/ml, which is within or above the therapeutic range of 0.0250 to 0.1120 µg/ml; diphenhydramine undergoes postmortem redistribution, and central postmortem levels may be about two to three times higher than peripheral or antemortem levels.). Diphenhydramine is a sedating antihistamine that causes more sedation than other antihistamines; this is the rationale for its use as a sleep aid. In a driving simulator study, a single dose of diphenhydramine impaired driving ability more than a blood alcohol concentration of 0.100%. The pilot had been diagnosed with memory loss about 8 months before the accident. It appears that he had some degree of mild cognitive impairment, but whether his cognitive impairment was severe enough to have contributed to the accident could not be determined from the available evidence. However, it is likely that the pilot's mild cognitive impairment combined with the psychoactive effects of diphenhydramine and possibly ethanol would have further decreased his cognitive functioning and contributed to his decision to attempt an aerobatic maneuver at low altitude in a non-aerobatic airplane.

The four engine aircraft departed Kinshasa-N'Djili Airport on a flight to Bukavu, carrying ammunition and two vehicles. Few minutes after takeoff, the crew reported technical problems and was cleared for an immediate return. Shortly later, the aircraft entered an uncontrolled descent and crashed in a prairie located in Nsele, about 20 km northeast of the airport, bursting into flames. The aircraft was destroyed and all 12 occupants were killed.

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.

En route from Toluca to Acapulco, the pilot encountered poor weather conditions. In limited visibility, the twin engine airplane struck hilly and wooded terrain in the Sierra de Chilpancingo, near San Vicente. The aircraft was destroyed by impact forces and a post crash fire and both occupants were killed.

Crashed in unknown circumstances near Hato Viejo, State of Cojedes. The aircraft was destroyed by a post crash fire and both pilots were killed. It is believed that the flight was illegal and the airplane was completing a drug smuggling flight.

The aircraft was engaged in a demonstration flight, taking part to an airshow at Chernoye Aerodrome, celebrating the 70th anniversary of the Antonov AN-2. The pilot-in-command completed a steep turn to the left to join the grassy runway. The airplane descended too low and impacted ground with its left wing and crashed 180 metres further, bursting into flames. The aircraft was totally destroyed and both occupants were killed.
