The Manaus Aerotáxi aircraft accident occurred on February 7, 2009, when a heavily overloaded Embraer EMB-110 Bandeirante of the Brazilian regional airline Manaus Aerotáxi had to ditch on a flight from Coari to Manaus in the Manacapuru River in the Amazon region . In the incident, 24 out of 28 people on board were killed. The Embraer EMB110, for which this is the most serious accident to date (March 2019), is only approved for 21 people.
The aircraft concerned was an Embraer EMB-110P1 Bandeirante built in 1981 with the serial number 110352. The aircraft had the aircraft registration PT-SEA . The twin-engine regional airliner was with two turboprop engines of the type Pratt & Whitney Canada PT6A-34 equipped and approved for 19 passengers and 2 crew members. The maximum take-off weight was 5670 kilograms.
The machine was initially delivered to the energy company Companhia Energética de São Paulo in November 1981 , where it received the aircraft registration PT-SEA , with which it was operated until the end. In August 1989 the regional airline Triton Táxi Aéreo took over the machine, in May 1999 the Brazilian San Marino Taxi Aéreo . Finally, the EMB 110 went to Manaus Aerotáxi. At the time of the accident, the machine had an operating performance of 12,686 operating hours.
The machine made a domestic flight from Coari to Manaus. Although the machine was only approved for 19 passengers, 26 passengers were taken on board. Together with the two crew members, there were 28 people on board. At take-off, the machine weighed 6414 kilograms, which meant that its maximum take-off weight was exceeded by 744 kilograms.
The plane left Coari at 12:40 p.m. At around 1:10 p.m., engine number 1 suffered a burst of flame . At 1:15 p.m., the crew contacted the Area Control Center (ACC) and stated that the machine was descending with 20 people on board. In fact, there were 28 people in the machine. The ACC instructed the crew to contact the air traffic control in Manaus. Finally, the pilots reported that they wanted to return to Coari due to heavy rainfall. The contact was then broken off and the machine disappeared from the radar screens at 1:24 p.m. A ditching was carried out at Manacapuru on the river of the same name, near its mouth in the Amazon .
Of the 28 people on board, 24 died, including the two pilots and 22 of the 26 passengers. Of the eight children on board, only one survived. Seventeen inmates belonged to the same family and were on their way to a relative's birthday in Manaus. From this group only two people survived. The cause of death for all victims was drowning.
The permissible payload of twin-engine aircraft is usually calculated in such a way that they remain airworthy even after an engine failure. The significantly overloaded Embraer began to lose altitude with only one engine in operation. Eleven years earlier, an incident with the same type of aircraft and an almost identical course of the accident had occurred in the region .
