Budget passenger carrier IndiGo has grounded some of its A320 Neo aircraft due to non-availability of spare engines from Pratt and Whitney.
"IndiGo confirms that a few A320 Neo aircraft have been grounded proactively due to non-availability of spare engines from Pratt and Whitney," the company said in a statement.
"The release of additional spare engines has been initiated by PW so that all aircraft can be expected to be in service soon. These engine changes are pre-planned and are as per the norms prescribed by the regulator to ensure safe operations."
