Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A310-203 airplanes. This AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This AD was prompted by reports that side link clevis bolts of the front engine mount do not meet the design service goal (DSG) requirements on airplanes equipped with General Electric Company CF6-80A3 engines. This AD requires repetitive replacement of all side link clevis engine mount bolts. We are issuing this AD to prevent failure of the front engine mount, and consequent possible departure of the engine.
