Air India crash Report Sparks Controversy Over Engine Restart Procedures and Safety Bulletins

New Delhi, India – A recent investigation report into an⁢ Air India crash has ignited a firestorm of debate within the aviation community, with experts questioning the clarity of findings and the relevance ⁣of cited safety advisories. The report, which details an incident where an aircraft experienced a significant loss of power, has left⁣ many seeking definitive answers, while others criticize its perceived vagueness.

Engine Restart ‍Procedures Under Scrutiny

A key point of contention revolves around the procedures a pilot would ⁢undertake to restart an engine that is losing power. While the report acknowledges the loss of engine power, it offers little insight into the specific actions taken or recommended for such a critical in-flight emergency. This lack of detail has ⁣drawn⁣ sharp criticism from aviation professionals.

Tim Atkinson, a seasoned aviation consultant and former air accident investigator in the UK, expressed his disappointment. ⁣”It is very disappointing to read a report which does provide a few salient‍ facts, but leaves many more questions,” Atkinson stated, highlighting the need for greater openness and detail in accident investigations. The ability of pilots to effectively manage and recover ‍from engine power loss is a cornerstone of ‍aviation safety, and any ambiguity in reporting such events is a cause for concern.

FAA Safety Bulletin and Potential faulty Switches

Adding another layer of controversy is the report’s reference to a 2018 Special Airworthiness Details⁢ Bulletin (SAIB) ⁤issued by the US Federal Aviation Governance (FAA). This bulletin alerted the aviation industry to reported cases where⁤ the locking feature on fuel cut-off switches in some ⁤Boeing 737 models had been disengaged. This disengagement could potentially allow the ⁤switch to be accidentally flipped, leading to unintended engine shutdown or power ⁤loss.

At the time of its release, the FAA classified this as an “airworthiness concern” but not an “unsafe condition” that would necessitate mandatory action through an Airworthiness Directive. Operators of various boeing models, including the 787, were advised to conduct simple ‍inspections.

The investigation report notes that Air India did⁣ not⁣ carry⁣ out these recommended inspections. This omission has fueled speculation that ‍the accident could have been caused by faulty‍ switches being inadvertently activated.However, in a subsequent internal note reviewed by the BBC, the FAA reiterated its stance that the issue did not compromise safety. Engineering sources also pointed out that the throttle control module on the crashed aircraft had been replaced twice, with the most recent replacement occurring two years prior to the accident. This process would typically ⁢involve replacing the associated cut-off switches.

Bjorn fehrm of Leeham Company⁣ dismissed the reference to the FAA’s advice ⁢as “totally irrelevant” to the accident in question, suggesting it was ‍a misdirection.

Regulatory Response and Lingering Questions

Despite ⁣the FAA’s continued assertion of safety, India’s Directorate General of Civil Aviation has mandated that operators of all aircraft covered by the original FAA bulletin‍ conduct inspections by July 21st. This directive underscores the potential seriousness with which aviation authorities are treating the issue, even if the direct link ‍to the Air India crash remains unconfirmed.

For former accident investigator ‍Tim Atkinson, the report’s ambiguity might have been intentional. he suggested that the vagueness could be ⁢a⁢ deliberate tactic to imply an explanation without explicitly stating it, a practice he finds detrimental to the integrity of investigative processes. “The very worst reports are those written to be read ‘between the lines’, and if that is what we have here, then it does no credit to the investigators,”⁣ Atkinson commented.

Those seeking definitive answers regarding ⁤the events of ‍Flight 171 may face a prolonged wait. While international protocols aim for the publication of final reports within a year of an accident, the reality frequently enough involves substantially longer timelines. The aviation industry, and the families affected by this incident, await further clarity⁤ and conclusive findings.
