Failure in hydraulic system causes flight to Manaus to return to Viracopos after takeoff A failure in the hydraulic system caused the pilot of the Azul plane to return to Viracopos Airport. The aircraft was destined for Manaus (AM) and made an emergency landing in Campinas (SP) at 9:41 am, this Saturday (11), according to the concessionaire Aeroportos Brasil Viracopos. In the audio obtained by EPTV, a TV Globo affiliate, the pilot told the landing tower that he had a "failure in the yellow hydraulic system" of the aircraft and asked to carry out a checklist on the equipment — listen to the audio above. "Pan-Pan, we have a failure in the aircraft's yellow hydraulic system, we are going to maintain this position, I still don't know how many spheres we are going to make in this position", said the pilot to the team at Campinas airport. ? According to an expert heard by g1, the hydraulic system is the set of equipment used to activate important functions of the aircraft, such as part of the brakes, flight controls and landing gear. In a statement, Azul denied that it was an emergency landing. According to the company, it was a preventive request for priority for landing. The company also said that the landing was motivated by technical reasons on the aircraft — see the full position below. PAN-PAN Flight AD2943 declared an emergency and returned to Viracopos, in Campinas FlightRadar24/reproduction Due to the failure, the pilot declared PAN-PAN, a code used to inform that there is an operational problem and request priority for landing. Unlike Mayday, which indicates a serious emergency and imminent risk, PAN-PAN signals a situation that requires attention, but does not place the aircraft in immediate danger. Another flight was impacted The concessionaire Viracopos Airport also reported that only one flight was impacted due to the incident, being diverted to Guarulhos Airport and that the landing and take-off operation resumed normally after the aircraft landed. Azul stated that the impacted customers received assistance and were re-accommodated on another aircraft, which took off to Manaus, and regretted any inconvenience.
