New Delhi – Air India has successfully completed precautionary inspections of fuel control switch locking mechanisms across its entire Boeing 787-8 aircraft fleet, with officials confirming no issues were discovered during the comprehensive safety checks. The Tata-owned airline conducted these critical inspections following a directive from the Directorate General of Civil Aviation (DGCA) issued earlier this week.
The inspections were initiated after the DGCA mandated that all operators of specific Boeing aircraft models must examine fuel control switches by July 21. This directive came in response to findings from the Aircraft Accident Investigation Bureau (AIIB) report into a devastating Boeing 787-8 Dreamliner crash in Ahmedabad that claimed 260 lives.
Investigation Reveals Critical Safety Concerns
The AAIB investigation uncovered alarming details about the Ahmedabad crash, revealing that fuel cutoff switches for both engines were moved to the cutoff position within a one-second interval at a critical altitude moments after takeoff. This finding prompted immediate regulatory action to ensure similar incidents could be prevented across the aviation industry.
According to the chronology outlined in the AAIB report, both fuel cutoff switches transitioned from ‘run’ to ‘cutoff’ positions just one second apart, occurring almost immediately after takeoff. The aircraft’s ram air turbine pump was subsequently deployed to supply hydraulic power as both engines fell below minimum idle rates. The entire sequence from takeoff to crash lasted merely 32 seconds.

Air India’s Proactive Safety Response
Air India officials emphasized that all Boeing 787-8 aircraft in their fleet had undergone throttle control module replacement according to Boeing’s prescribed maintenance schedule. The fuel control switch forms an integral component of this throttle control module, making its proper functioning crucial for flight safety.
“Over the weekend, our engineering team initiated precautionary inspections on the locking mechanism of fuel control switches on all our Boeing 787 aircraft,” stated an Air India official. “The inspections have been completed and no issues were found.”
This information was communicated as an internal update to Air India pilots through the flight operations team, ensuring all crew members remained informed about the safety status of their aircraft.
Regulatory Compliance and Safety Standards
The DGCA directive enforced compliance with a Federal Aviation Administration bulletin originally issued in December 2018. This FAA warning highlighted potential disengagement of fuel control switch locking features in operators of certain Boeing 737 aircraft models. However, the fuel control switch design, including its locking feature, remains similar across various Boeing aircraft models, particularly part number ‘4TL837-3D’, which was installed in the Boeing 787-8 that crashed in Ahmedabad.
Significantly, the AAIB report noted that Air India had not previously carried out inspections recommended in the 2018 FAA advisory on fuel control switch safety. This was attributed to the bulletin being classified as “non-mandatory” at the time of its initial release.
Extended Fleet Safety Measures
Beyond the Boeing 787 inspections, Air India also conducted comprehensive safety checks on its Boeing 737 Max fleet operated by Air India Express. Officials confirmed that the entire Boeing 737 Max fleet underwent similar inspections, with no issues discovered during these examinations.
These extensive safety measures demonstrate Air India’s commitment to maintaining the highest safety standards across its diverse aircraft portfolio, ensuring passenger safety remains the top priority in all operations.
Technical Specifications and Safety Protocols
The fuel control switch serves as a critical safety component in modern aircraft, controlling fuel flow to engines during various flight phases. The locking mechanism prevents inadvertent switch activation that could lead to engine shutdown during critical flight operations.
Air India’s engineering teams followed strict protocols during the inspection process, examining each aircraft’s fuel control switch locking mechanism according to manufacturer specifications and regulatory requirements. The thoroughness of these inspections reflects the airline’s dedication to maintaining operational safety standards.
Industry-Wide Safety Implications
The Ahmedabad crash investigation has prompted broader discussions about fuel control switch safety across the aviation industry. The similarities in fuel control switch design among various Boeing aircraft models suggest that safety protocols developed for one model may have applications across multiple aircraft types.
Air India’s successful completion of these inspections without discovering any issues provides reassurance to passengers and regulators alike. The airline’s proactive approach to safety compliance sets a positive example for the industry, demonstrating how carriers can effectively respond to regulatory directives while maintaining operational efficiency.
Concluding Statement
Air India’s comprehensive inspection of fuel control switches across its Boeing 787 fleet represents a significant step toward enhanced aviation safety. The successful completion of these inspections, combined with the airline’s proactive maintenance practices, reinforces confidence in Air India’s commitment to passenger safety. As the aviation industry continues to evolve, such thorough safety protocols remain essential for maintaining public trust and ensuring the highest standards of flight safety across all operations.
