Airworthiness Directive · Amendment 39-19516 · Doors
Airbus SAS Airplanes
This AD applies to Airbus SAS Model A350-941 airplanes, certificated in any category, as identified in Airbus Service Bulletin A350-52-P012, dated September 7, 2017.
We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by reports that, for multimaterial (hybrid) joints of the passenger door frame fittings, the interfay sealant was not applied between all surfaces of the joint parts. This AD requires modification of the hybrid joints of the passenger doors by applying additional corrosion protection to the hybrid joints of the passenger door frame fittings. We are issuing this AD to address the unsafe condition on these products.
Within 48 months after the date of issuance of the original certificate of airworthiness or the original export certificate of airworthiness, whichever occurs earlier: Apply additional corrosion protection (e.g. primer/topcoat or corrosion prevention compound) to the hybrid joints of the left-hand and right-hand sides of the passenger door frame fittings at doors 1, 2, 3 and 4, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A350-52-P012, dated September 7, 2017.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
