AD: Engine Alliance Turbofan Engines

AD NUMBER: 2016-05-07

PRODUCT: Certain Engine Alliance (EA) GP7270 turbofan engines.

ACTION: Final Rule

SUMMARY: This AD was prompted by reports of the installation of non-conforming honeycomb cartridges in the high-pressure compressor (HPC) adjacent to the HPC rotor stage 2 to 5 spool and stage 7 to 9 spool.

This AD requires removal and replacement of the affected HPC rotor stage 2 to 5 and stage 7 to 9 spools and adjacent honeycomb cartridges.

The FAA is issuing this AD to prevent failure of the HPC rotor stage 2 to 5 and stage 7 to 9 spools, which could lead to uncontained engine failure and damage to the airplane.

DATES: This AD is effective April 19, 2016.

FMI: AD
