IndiGo, India’s largest budget carrier with a fleet of 48 Airbus A320 airliners, has awarded SriLankan Engineering its largest contract for maintenance of 26 C-checks through 2012. This is the fourth consecutive year IndiGo has outsourced to SriLankan and it is the largest overseas outsourcing of maintenance, repair and overhaul work by an Indian carrier. The contact has been awarded at a time when onerous taxes appear to be making Indian MRO providers uncompetitive.
