The US Federal Aviation Administration (FAA) has said the fuel control switches in Boeing aeroplanes are safe, following their reported involvement in a fatal Air India crash that killed 260 people in June.

Apparent gaps in AAIB’s preliminary report means that while a key factor in the disaster—cutting of the fuel supply—has been confirmed, not much else has. FAA’s insistence that the accident does not change its evaluation of the fuel switch problems counters the only switch-related technical issue discussed in the report.

The US Federal Aviation Administration has issued a notice to its international counterparts that fuel control switches in Boeing aeroplanes like the Dreamliner involved in last month’s fatal Air India crash do not pose a safety issue.
