Boeing, FAA say fuel switch locks are safe as Air India crash probe continues

The preliminary report points to possible fuel switch issues in the fatal crash, but US regulators and Boeing say inspections remain advisory, not mandatory, amid calls from pilot groups for a thorough, unbiased inquiry.

The US Federal Aviation Administration and Boeing have privately issued notifications that the fuel switch locks on Boeing planes are safe, a document seen by Reuters showed and four sources with knowledge of the matter said.
