This is what I'm going by:
The report said that in December 2018, the US Federal Aviation Administration issued a special airworthiness information bulletin based on reports from operators of model 737 planes that the fuel control switches were installed with the locking feature disengaged.
The airworthiness concern was not considered an unsafe condition that would warrant an airworthiness directive – a legally enforceable regulation to correct unsafe conditions.
The same switch design is used in Boeing 787-8 aircraft, including Air India’s VT-ANB, which crashed. The report added: “As per the information from Air India, the suggested inspections were not carried out as the SAIB was advisory and not mandatory.”
