DGCA Clarifies AI-132 Fuel Switch Incident: No Malfunction, Design Behavior Explained

• Air India flight AI-132 from London to Bengaluru experienced a fuel control switch issue before takeoff, similar to a previous AI-171 crash.
• The crew observed the fuel control switch not fully locking into the 'run' position twice, but it latched correctly on the third attempt.
• DGCA investigation found no mechanical failure; the switch's movement was due to design behavior when pressed at an incorrect angle.
• Tests conducted under Boeing's guidance confirmed the pull-to-unlock force was within limits, indicating no technical fault.
• Boeing advised Air India to circulate correct operating procedures to all crew members to prevent future misunderstandings.

Why It Matters: The AI-132 fuel switch incident was a design behavior, not a malfunction, clarified by DGCA after investigation.
