The flight returned to its base due to low oil pressure in one of its engines for maintenance check.
"Within an hour into flight, engine low pressure was detected in one of the engines of IndiGo ATR 72-600. The aircraft was being ferried (non revenue flight/no revenue passengers onboard), from Toulouse (France) to India." read an official note.
"As a precautionary measure the aircraft immediately returned to Toulouse for maintenance checks. Post maintenance the aircraft was released for ferry. The matter has been brought to the notice of the regulator," it added.
