Obligations

The initial approval audit involves the following:

  • interview with the accountable manager;

Two types of findings may appear in the audit report:

  • Level 1 finding:
    • definition: significant non-compliance with the requirements of the regulations that lowers the level of safety and presents a serious hazard to flight safety;
    • consequence: the DAC is entitled to suspend the approval process based on the magnitude of the level 1 finding until a corrective action is implemented to remedy the non-compliance issue;
    • obligation of the organisation: implement corrective and, if necessary, preventive actions to remedy the non-compliance issues in accordance with the current regulations;
  • Level 2 finding:
    • definition: significant non-compliance with the requirements of the regulations that may lower the level of safety and present a serious hazard to flight safety;
    • consequence: the DAC may grant:
      • a short period of time (approximately 3 months), from the date of the written notification of the finding in which the organisation is requested to implement a corrective action, to remedy the non-compliance issue;
      • a 3-month extension based on an action plan, at the request of the organisation in question;
