Pratt's Balky new jet engines get stepped-up scrutiny from India

Regulators in India are stepping up scrutiny of Pratt & Whitney’s new jet engines as the U.S. manufacturer tries to overcome glitches that have grounded some Airbus SE planes.

The geared turbofan engines are now being inspected after as few as 350 hours of operation, down from initial plans for every 1,000 hours, Civil Aviation Minister Ashok Gajapathi Raju said in an interview in New Delhi. Power plants that don’t meet all requirements will be pulled from service, and the government denied Pratt’s request to allow some failed engines to continue to be used for short intervals, he said.

Pratt, a unit of United Technologies Corp., is rushing to address the flaws after spending $10 billion developing the geared turbofan for narrow-body planes such as Airbus’ A320neo. The engine has had a rocky introduction amid delivery delays and technical issues, including some components that have not been as durable as expected. The company is ramping up production rates and introducing fixes for the faults.
