## Abstract

We are adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GE90 turbofan engines. This AD was prompted by a report of an engine and airplane fire. This AD requires replacing affected fuel/oil lube/servo coolers ("main fuel oil heat exchangers") with a part eligible for installation. We are issuing this AD to correct the unsafe condition on these products.
