Официально не зафиксировано ни одного случая подобного отказа на самолетах Boeing.
Ну как сказать. В предварительном отчете прямо сказано:
The FAA issued Special Airworthiness Information Bulletin (SAIB) No. NM-18-33 on
December 17, 2018, regarding the potential disengagement of the fuel control switch locking
feature. This SAIB was issued based on reports from operators of Model 737 airplanes that
the fuel control switches were installed with the locking feature disengaged. The airworthiness
concern was not considered an unsafe condition that would warrant airworthiness directive
(AD) by the FAA. The fuel control switch design, including the locking feature, is similar on
various Boeing airplane models including part number 4TL837-3D which is fitted in B787-8
aircraft VT-ANB. As per the information from Air India, the suggested inspections were not
carried out as the SAIB was advisory and not mandatory. The scrutiny of maintenance records
revealed that the throttle control module was replaced on VT-ANB in 2019 and 2023.
However, the reason for the replacement was not linked to the fuel control switch. There has
been no defect reported pertaining to the fuel control switch since 2023 on VT-ANB.
