AMC2 ARO.GEN.305(c) Oversight programme (c) stipulates that audits should include at least one on-site audit within each oversight planning cycle. What is meant by an 'on-site audit' in this sentence? Could it be so that every audit undertaken by an NAA could be performed while sitting in the NAA's office and reviewing operator's documents and procedures and only one of those audits should be undertaken in a way that NAA inspectors actually visit an operator on-site?
Reference: Regulation (EU) No 965/2012 on Air Operations, Annex II (Part ARO, ARO.GEN and ARO.RAMP)
There is no further guidance on how many on-site audits should actually be performed. This decision depends on the confidence of the authority in the operator, on results of past certification and/or oversight activities required by ARO.GEN and ARO.RAMP and on the assessment of associated risks. The number of on-site audits is therefore part of the oversight responsibility of the authority.
