IndiGo's PW1100G engines 'well within safety limits': airline

Modifications to the Pratt & Whitney PW1100G geared turbofan engines that power IndiGo's Airbus A320neo aircraft are under way, the carrier has confirmed. COO Wolfgang Prock-Schauer said the airline had received safety clearance from the US FAA to continue operating the engines and that they were "well within the [safety] limits". He reveals that for IndiGo's PW1100Gs, in-flight engine shutdowns were occurring at a rate of 0.02, as compared with the FAA's limit of 0.05. "The situation is completely under control," says Prock-Schauer. His comments follow a directive issued by India's Directorate General of Civil Aviation Jan 17 to IndiGo and GoAir, instructing them to conduct a series of inspections on the engines to identify and correct potential low-pressure turbine and dry face seal failures. <br/>
