IndiGo Airlines has grounded five Airbus A320neo planes at New Delhi airport after issues with Pratt & Whitney aircraft engines, India`s biggest low-cost carrier said on Wednesday.
The planes are expected to be back in service in the second half of August, IndiGo owner InterGlobe Aviation said in a statement.
In March, India`s aviation regulator ordered Airbus A320neo aircraft fitted with certain Pratt & Whitney engines to be grounded immediately.
United Technologies-owned Pratt & Whitney said separately it was working with airlines to address the issue.
Engine removals were being planned and coordinated with the airlines as Pratt & Whitney installs newer engines, it said via email.
InterGlobe Aviation shares ended 1.8 percent lower on Wednesday after hitting a 14-month low earlier on India`s National Stock Exchange.
