Production without POA - 21F

The Agency may authorize production in accordance with Commission Regulation (EU) No 748/2012, Part 21.F, when the following is provided:

  1. Applicant intends to manufacture parts, appliances and/or materials intended for use in aviation or air navigation as parts of type-certified products (excluding simulators, ground equipment and tools);
  2. The Agency establishes that the use of Part 21.G would be inappropriate and therefore Part 21.F is applicable. The difference between the two types of organization lays in quality management. There are cases where a quality system that involves independent control and constant internal auditing process of the company is not reasonable or feasible. In deciding whether to apply Part 21.F, the competent authority may consider one or more of the following criteria:
    • there is no serial production in the company;
    • the production is only seldom or occasional;
    • small scale production;
    • The manufacturing technology is simple and allows effective control during the manufacturing process;
    • The company is a very small organisation.


The letter of agreement shall be issued for a limited duration not exceeding one year.
