More groundings for PW1100G equipped aircraft

The ESA has issued an Emergency AD requiring all A320neo aircraft equipped with PW1100G geared turbofan engines that have modified aft hubs to be grounded within 3 cycles. Aircraft equipped with one modified engine can continue flying, but must stop extended over water flights within one cycle.

The problem appears to be with the knife edge seal in the modified hub. The affected engines are more susceptible to in flight shutdowns. "Several" aircraft have suffered failures in flight or on takeoff.

Airbus has informed Indigothat all A320neo deliveries are on hold until further notice. Indigo has also grounded thee aircraft powered by the PW1100G.

Yikes. That sucker is still quite buggy. Seems simple in concept but the execution has bedeviled them. Would you want to fly on one even if the other engine was fine?

We had a hard landing in the King Air at Reno a few years back and they wanted to replace a gear piece to ensure safety margin. But told me would go continue the transport cause it should be okay If I wanted to. "should be"? Nope not going anywhere till its fixed. Glad to see Airbus and Indigo taking steps

And, ironically, their problems have nothing to do with the gear. This one is primarily about the knife-edge seals, which they've had for some time.

It's a shame that these more mundane problems are plaguing this cool, new engine.

They recently changed the hub configuration as part of a modification for other issues with reliability.
