Boeing issued (13-Apr-2018) a statement on issues related to Rolls-Royce Trent 1000 'Package C' engines and increased inspections for the engine fleet. According to Boeing:
- About 25% of the 787 fleet is powered by the Rolls-Royce engine variant;
- The issue does not affect current production 787s, the Trent 1000 Package B, Trent 1000 TEN or GEnx-1B engines;
- An existing EASA airworthiness directive for the Package C engine requires inspections of an intermediate pressure compressor blade at certain flight cycles. If a durability issue is found, the blade will be replaced. This is a known issue and Boeing will continue to work with Rolls-Royce, customers and regulators to fully resolve it;
- Boeing is deploying support teams to mitigate service disruption. [more - original PR]
