  1. In manufacturing process section, could you please replace “silver plating” by “passivation and lubrication”?

    In QTP section, no document is attached. Maybe there is no need or is it an omission?

    In Process Flow Chart, passivation is subcontracted to AFS MECAERO whereas on ASD-CERT website, Protec Industrie is mentioned for passivation. Could you please clarify?
    Another thing about passivation, could you please add CoC?

    Reusability test – 15 cycles: test was carried out by applying “m” note which states that “for all-metal self-locking nuts made of stainless steel with MoS2-type dry-film lubrication, this test shall be carried out over 5 cycles in order to avoid any risk of seizing”.
    These nuts are made of nickel-base alloy, which could be considered as “stainless steel”, but this alloy is a super alloy. Anyway, agreed.

    Many thanks.
    Regards.

    1. In manufacturing process section, could you please replace “silver plating” by “passivation and lubrication”? : I will ask Christelle Festaud to do it as I could not change directly from the website.
      In QTP section, no document is attached. Maybe there is no need or is it an omission? : See QTP enclosed on the category “Additional Documents” + I sent a copy to Christelle Festaud;
      In Process Flow Chart, passivation is subcontracted to AFS MECAERO whereas on ASD-CERT website, Protec Industrie is mentioned for passivation. Could you please clarify? : I agree, there was a discrepancy. When we create tthe ACP Document the passivation was planned to be subcontracted to Protec Industries but for several reasons (cost, capacity) we change the subcontractor it is the reason why the flow chart was submitted to AFS Mecaero.

      Another thing about passivation, could you please add CoC? : See CoC enclosed on the category “Additional Documents” + I sent a copy to Christelle Festaud.
