## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain RRD TAY 611-8, TAY 620-15, TAY 650-15, and TAY 651-54 series turbofan engines with ice-impact panels installed in the low pressure (LP) compressor case. This AD requires inspecting all ice-impact panels and fillers in the LP compressor case for certain conditions, and if necessary, replacing any ice-impact panels and fillers that have those conditions. This AD results from two reports of ice-impact panels that released during flight, one of which resulted in reduction of power in both engines. We are issuing this AD to prevent release of ice-impact panels due to improper bonding that can result in loss of thrust in both engines.
