Mumbai: The global pilots’ body remarked that the preliminary investigation report of the AI-171 raises many questions and does not provide answers. The global association also stated that the guesswork based on the report will not be helpful to the good conduct of the investigation.

The investigation report says Air India did not carry out those inspections - prompting speculation that the accident could have been caused by faulty switches being flipped by accident. However, in an internal note seen by the BBC, the FAA has since reiterated its belief that the issue did not compromise safety.
