Unsafe Condition

A case was reported by an A350-1041 operator where a front engine mount primary pin had moved axially out of place. Investigations revealed that washers with incorrect P/N had been installed on the subject engine mount pins. A350-941 aeroplanes are also considered as potentially affected. The engine mount assembly has a fail-safe design, loads are carried by two links in the left-hand and right-hand positions and in case of failure, a ``fail-safe'' link pin in the centre position is activated and takes the loads. This condition, if not detected and corrected, may lead to disengagement of a primary engine mount pin, which along with an additional failure of the ``fail-safe'' link pin, could possibly result in in-flight detachment of an engine, with consequent reduced control of the aeroplane.
