Four-Year Compliance Timeline for Engine Debris Protection

The FAA has proposed a new rule requiring operators of Rolls-Royce-powered Boeing 787s to replace certain fan cowl parts within four years to ensure engine protection from debris in the event of a serious engine failure. The proposal addresses a certification gap following design changes to the Trent 1000 engines and is based on a bulletin issued by Boeing in February. The issue has not been linked to any in-service incidents, and Boeing is developing reinforced cowl panels to resolve the issue. The proposal was reported by an unknown source.
