Ljud från cockpit: Piloterna sökte lösning i handbok

Röstupptagningar från cockpit avslöjar hur piloterna på Lion Air-planet sökte i en handbok för att förstå hur de skulle kunna räta upp planet igen, rapporterar källor Reuters. Planet störtade i Javasjön i oktober förra året och alla 189 personer ombord omkom.

Utredningen av kraschen har på nytt aktualiserats sedan flygplansmodellen Boeing Air 737 Max belagts med flygförbud efter en andra dödlig krasch i Etiopien.

Utredare undersöker bland annat varför flygets dator beordrade planet att dyka som ett svar på en felaktig sensor och om piloterna hade fått adekvat utbildning.

Detta är första gången som ljudupptagningens innehåll blir känt för allmänheten. Reuters, som hänvisar till tre anonyma källor, betonar att de varken har haft tillgång till själva inspelningen eller en transkribering.

bakgrund
 
Lion Air Flight 610
Wikipedia (en)
Lion Air Flight 610 was a scheduled domestic flight operated by the Indonesian airline Lion Air from Soekarno–Hatta International Airport in Jakarta to Depati Amir Airport in Pangkal Pinang. On 29 October 2018, the Boeing 737 MAX 8 operating the route crashed into the Java Sea 12 minutes after takeoff, killing all 189 passengers and crew. It was the first major accident involving the new Boeing 737 MAX series aircraft, introduced in 2017, and the deadliest involving a 737, surpassing Air India Express Flight 812 in 2010. It is the worst accident in Lion Air's 18-year history, surpassing the 2004 crash in Surakarta that killed 25, and the second deadliest aircraft accident in Indonesia behind Garuda Indonesia Flight 152. The Indonesian government deployed a search and rescue operation which found debris early in the morning and recovered human remains from a 150-nautical-mile (280 km) wide area. The first victim was identified two days after the crash. The flight data recorder was located on 1 November and recovered for analysis. One member of the volunteer rescue team died during recovery operations. The cockpit voice recorder was found on 14 January 2019.Preliminary investigations revealed serious flight control problems that traumatized passengers and crew on the aircraft's previous flight, as well as signs of Angle of attack (AoA) sensor and other instrument failures on that and previous flights, tied to a potential design flaw involving the Maneuvering Characteristics Augmentation System (MCAS) of the 737 MAX series. As a result, the United States Federal Aviation Administration and Boeing issued warnings and training advisories to all operators of the 737 MAX series to avoid letting the MCAS cause an abrupt dive similar to the Lion Air flight. These advisories were not fully implemented, however, and the design issues are suspected to be involved in the Ethiopian Airlines Flight 302 crash on 10 March 2019, leading to the worldwide grounding of all 371 operating 737 MAX aircraft.
