DGCA Orders Boeing Fuel Switch Checks
The Directorate General of Civil Aviation (DGCA) has directed all Indian airlines operating Boeing 787 and select Boeing 737 aircraft to inspect the fuel control switch locking mechanism by July 21, 2025. This action follows a recent investigation into the Air India Flight 171 crash, where both engines lost power shortly after takeoff due to a sudden cut in fuel flow.
Background of the Directive
Preliminary findings from the crash revealed that both engine fuel switches had moved from the “RUN” to “CUTOFF” position moments before the engines lost thrust. Cockpit voice recordings confirmed that the pilots did not intentionally initiate the cutoff, suggesting a possible mechanical or procedural issue.
Although the final cause is yet to be confirmed, the DGCA has acted swiftly to prevent any recurrence. Airlines have been asked to immediately check whether the locking mechanism on the fuel switches functions correctly—ensuring the switches cannot move unintentionally.
Industry-Wide Response
Air India, IndiGo, and SpiceJet are among the carriers affected. Several have already begun inspections. While no irregularities have been found in initial checks, the DGCA has made it mandatory for all operators to submit compliance reports.
The regulator has warned that failure to complete inspections by the deadline could result in aircraft being grounded. The move reflects a strong precautionary approach to flight safety, especially given previous international advisories warning of similar risks.
Boeing’s Position and Global Actions
Although Boeing maintains that the switch design is safe, airlines worldwide—including those in the Middle East and Southeast Asia—have begun voluntary inspections. The issue relates to an older technical advisory issued by American regulators, which is now being revisited following the Air India incident.
The DGCA’s step underscores India’s intent to prioritise aviation safety and maintain public confidence in its civil aviation system.
