Aerospace Surveillance Audits

Airplane, aerospace, AS9100


In reference to AS9104/1 clause 8.2.2.f “Auditing of the entire AQMS standard on all shifts is required for initial and recertification audits. For surveillance audits, the planning shall include coverage of multiple shifts, when the audit plan activities occur across multiple shifts.”

The identified process is “Production” but shift one conducts assembly and shift two kits parts for assembly. Since “Production” spans both shifts but “activities” are distinct on each shift, do you have to audit both shifts during every surveillance audit?

It would be required that Production be audited on both shifts when it is planned for surveillance audits.  For example, if the acquire business, design & development, and procure parts/materials were audited in Annual Surveillance #1 and production and procure parts/materials were audited in Surveillance #2, then second shift would only require to be audited during Surveillance #2.

Sampling Foils, Films, and Labels

Manufacturing, inspection, exclusions


My question is about sampling aluminium foils, films used in packaging and sticker labels received in rolls which are wound around a core. I can decide to chose the number of rolls to sample from using the tables given in Z1.4, but how should I decide on the amount of stickers and aluminium foil and film to be sampled? I ask this question since it is practically impossible to sample from within a wound roll.

The ANSI Z1.4 and Z1.9 standards might be applicable when all units do not have the same probability of being selected.  Since you cannot sample units closer to the core, and defects would never be detected unless they occur at the end of the roll, I would recommend a different strategy, either using a vision system (100% inspection) or in process inspection.

If you want to use the standard, the sample size should be based on the number of samples, not the number of rolls.  For example, a roll with 5000 labels would be an N=5000 not N=1.
