Vistara B737 returned midway after a whistling sound heard in the cockpit

A Mumbai-bound flight of Vistara returned to Delhi after a “whistling” sound was heard on the right side of the Boeing B737 aircraft cockpit, a DGCA official said.

The DGCA ( Directorate General of Civil Aviation) has ordered a probe into the incident even though no structural deficiency was observed during the preliminary ground inspection of the plane.

The airlines – a joint venture between Tata and Singapore Airlines Limited, confirmed the return of its Mumbai flight UK 951 back to Delhi, saying that the pilot decided to do so after a technical snag was detected shortly after its take-off.

An alternate aircraft was immediately arranged to fly the passengers to their destination.

Vistara operated its B737-800 aircraft with registration VT-TGB while operating flight UK 951, which was involved in air turnback to Delhi as a whistling sound was heard from the right side of the cockpit.

The Tata Group also owns Air India beside Vistara its low-cost international arm Air India Express and it holds a majority stake in low-cost airline AirAsia India.
