NEW DELHI: An IndiGo flight operating from Mumbai to Jaipur made an emergency landing at its destination on Saturday after pilots observed the fuel quantity reducing abnormally during cruise.
Suspecting fuel leak from an engine of the Airbus A320 (VT-IVK), pilots of flight 6E-998 shut that engine down and declared an emergency. Since twin engine planes can land safely on one engine, this one also did so at Jaipur.

An IndiGo spokesperson said: “IndiGo A320 Neo (new engine option) was operating Mumbai-Jaipur flight on June 22. On top of descent at Jaipur, pilot observed number 1 fuel tank quantity decreasing. He suspected fuel leak from (that) engine and carried the checklist. Safe single engine landing was made. Detailed checks were done post arrival. No fuel leak was noticed. However, fuel quantity indication of (number) 1 tank was found fluctuating. Same was rectified. Aircraft is back in service.” This A320 Neo snag was not related to engine.
However, the airline faced an issue with its Pratt & Whitney (PW) engines on another A320 family Neo last week. A just over month old A321 Neo was flying as 6E 2031 from Delhi to Bangalore when pilots got a message for a snag in one of its two Pratt and Whitney (PW) engines. The aircraft (VT-IUD) landed in Bangalore safely and was grounded there. It was later flown as a ferry flight — only crew and no passengers — to Delhi where the engine was replaced.
Commenting on this, the IndiGo spokesperson said: “There was oil chip message on IndiGo A321 Neo operating Delhi-Bangalore on June 21. As per guidelines, aircraft was ferry flown to Delhi where detailed checks were done. Engine was required to be replaced. Engine change has been done and the aircraft is back in service. The (recurring snag) oil chip concern on Neo has by and large been fixed. IndiGo faced this occurrence after more than three months.”

A PW spokesperson said that the Mumbai-Jaipur flight scare was not related to engine.
IndiGo, the world’s largest customer for the Airbus 320/21 Neo aircraft, had last week opted for CFM engines over PW engines for this plane after facing snags on them over past two years. IndiGo placed an order worth $20 billion for CFM’s LEAP-1A engines for 280 A320 and A321 Neo planes. CFM International is a 50/50 joint company between GE and Safran Aircraft Engines.
In India, only IndiGo and GoAir use PW-powered A320/21 Neos.
