Why Did Air India's Boeing 787 Fly From London With a Fuel Switch Issue?

The UK Civil Aviation Authority (CAA) has formally requested details from Air India regarding a safety incident. The issue involves a Boeing 787-8 Dreamliner aircraft. The flight departed London Heathrow (LHR) with a reported fuel control switch problem. The flight, AI132, was heading to Bengaluru, India. The CAA warned of potential regulatory action if the airline’s response is unsatisfactory.

Incident Details and Regulatory Warning

The incident occurred on February 1, 2026. During engine start at London Heathrow, the crew observed an issue. The left engine's fuel control switch did not latch in the 'run' position twice. It secured properly on the third attempt.

The pilot reported a possible defect upon landing in Bengaluru. The aircraft was immediately grounded for technical checks.

The CAA sent a letter to Air India on February 3, 2026. It expressed "serious concern" over the flight's departure. The regulator gave Air India one week to provide a full explanation. This must include a comprehensive root-cause analysis. A preventive action plan for the entire Boeing 787 fleet is also required.

Failure to provide a complete response could lead to restrictions. The CAA may impose increased scrutiny on Air India’s UK operations.

Critical Safety Context

This incident is under intense scrutiny due to recent history. The fuel control switches regulate jet fuel flow to the engines. A similar malfunction was a factor in a fatal Air India Dreamliner crash (AI 171). That accident occurred in Ahmedabad on June 12, 2025.

• The switches were at the center of the previous fatal accident investigation.
• Any fault in fuel management systems is treated with high urgency.
• The outcome will depend on mechanical or procedural oversight findings.

Airline and Indian Regulator Response

Air India quickly responded to the safety concern. The airline grounded the specific aircraft for inspection. It also completed precautionary re-inspections across its operational Boeing 787 fleet. Air India has a fleet of 33 Boeing 787s.

The airline stated that no issues were identified during these checks. An Air India spokesperson confirmed they will respond to the UK regulator.

India's Directorate General of Civil Aviation (DGCA) also weighed in. The DGCA suggested that correct operating procedures were not followed. They have directed Air India to ensure all crew strictly adhere to manufacturer-recommended procedures.

Industry Impact

This event highlights the global nature of aviation safety oversight. Regulators like the CAA can exert authority over foreign carriers. This is true when operations occur within their airspace or airports. The focus is on safety assurance procedures and airworthiness documentation. The incident puts pressure on Air India’s maintenance and crew training protocols. This is especially true following the airline’s recent fatal crash.
