Despite there being no affected US airlines, the FAA is issuing an Airworthiness Directive ordering the replacement of the LPT blades on the PW1100G geared turbofan within 90, 180, 270, or 360 days depending on serial number of the engine. There have been a reported 41 blade failures since 2017, in the third stage LPT. This results in a loss of thrust in the engine.

The FAA order is expected to prompt other regulators to issue similar orders. India has already given their airlines until January to ensure all PW1100G engines have the new third stage blades. It's expected to cost airlines just under $800,000 per engine to replace them.

Regarding the cost, are you sure that the airlines will pay the bill for the retrofit? FAA just estimated ~800k per engine but did not say anything about who will pay the bill. Since the engine has a somewhat rocky history (airlines even grounding airplanes due to engine failures and/or problems) wouldn't one assume that PW will pay for the replacement parts and retrofit?

(obviously not including the cost of lost revenue during the retrofit)

It will depend on the contract that they have with Pratt. Pratt should assume the cost for most of the replacements, but there are some airlines that will end up eating at least part of the cost for it.
