Pratt gearbox issue said to cause Airbus A320neo grounding

An Airbus A320neo jet suffered an in-flight engine failure after a gearbox component malfunctioned, according to people familiar with the matter, marking the latest glitch to hit the Pratt & Whitney turbine. The model’s biggest operator, IndiGo, said Wednesday it was forced to carry out an emergency landing in response to a loss of oil pressure during the flight Monday. The latest issue concerns an accessory gearbox and isn’t integral to the fan-drive gear system that makes the fuel-saving engine so innovative, said the people. Indigo, which didn’t specify what caused the fault, said it grounded the plane and is conducting further checks. Airbus and Pratt & Whitney said they’re working to minimise disruption to the carrier. The incident follows a run of issues that have afflicted Pratt-powered versions of the A320neo. <br/>
