GM 21.A.124(b)(1)(i) Applicability - Inappropriate approval under Subpart G

• ED Decision 2012/020/R found in: Initial Airworthiness and Environmental Protection (748/2012) Part-21 Part-21L (Jul 2024)

GM 21.A.124(b)(1)(i) Applicability – Inappropriate approval under Subpart G ED Decision 2012/020/R The issue of a letter of agreement of production under Part 21 Subpart F may be agreed by the competent authority when: 1.       The applicant produces or intends to produce aeronautical products, parts and/or appliances intended for airborne use as part of a type-certificated product (this excludes simulators, ground equipment and tools), and 2.       The competent authority determines that Part 21 Section A Subpart G would be inappropriate, and consequently Part 21 Section A Subpart F applies. The main difference between Part 21 Section A Subparts G and F is that Subpart G requires the existence of a Quality System which provides the competent authority with the necessary confidence to grant to the manufacturer the privileges of certifying its own production. There are situations where a Quality System, including independent monitoring and continuous internal evaluation functions, is not justified and /or feasible. In making the determination that Subpart F may apply, the competent authority may take into account one or a combination of parameters such as the following: — no flow production (infrequent or low volume of production). — simple technology (enabling effective inspection phases during the manufacturing process). — very small organisation. ##### GM 21.A.124(b)(1)(i) Applicability – Inappropriate approval under Subpart G *ED Decision 2012/020/R* The issue of a letter of agreement of production under Part 21 Subpart F may be agreed by the competent authority when: 1.
