AD/BR700/6 - Independent Overspeed Protection - CANCELLED

This document officially cancels a previous aviation safety rule (Airworthiness Directive AD/BR700/6) that required checks or fixes for independent overspeed protection units in Rolls-Royce BR700 series jet engines. The German aviation authority confirmed that all affected units have been replaced, so the safety rule is no longer necessary. The cancellation took effect on 24 November 2005. This affects airlines and aircraft operators using these specific engines, essentially telling them they no longer need to comply with the previous directive.

Key points:

• What: Cancellation of a safety directive about engine overspeed protection
• Who: Operators of aircraft with Rolls-Royce BR700 series engines
• Why: The safety issue has been resolved—all problematic parts have been replaced
• When: Effective 24 November 2005
