What types of items are excluded from the scope of production under Subpart F as per GM 21.A.124(b)(1)(i)?

Simulators, ground equipment and tools are excluded from the scope of production under Subpart F, as the applicant must produce or intend to produce aeronautical products, parts and/or appliances intended for airborne use as part of a type-certificated product.

Does GM 21.A.124(b)(1)(i) state that a Quality System is always required for production under Subpart F?

No, GM 21.A.124(b)(1)(i) states that Subpart G requires a Quality System, but for Subpart F, the determination that Subpart F may apply is based on situations where a Quality System, including independent monitoring and continuous internal evaluation functions, is not justified and/or feasible.

What is the role of the competent authority in deciding between Subpart G and Subpart F for production approval?

The competent authority determines whether Part 21 Section A Subpart G would be inappropriate, and consequently Part 21 Section A Subpart F applies. The competent authority may take into account parameters such as no flow production, simple technology, or very small organisation in making this determination.

Is the issue of a letter of agreement under Subpart F mandatory when an applicant produces parts for a type-certificated product?

No, the issue of a letter of agreement under Subpart F may be agreed by the competent authority when the applicant produces or intends to produce such parts and the competent authority determines that Subpart G would be inappropriate. It is not mandatory; it is subject to the competent authority's determination.

What does 'no flow production' refer to in the context of determining the applicability of Subpart F?

'No flow production' refers to infrequent or low volume of production, which is one of the parameters that the competent authority may take into account when determining that Subpart F may apply instead of Subpart G.

How does 'simple technology' factor into the decision to apply Subpart F?

Simple technology, which enables effective inspection phases during the manufacturing process, is one of the parameters that the competent authority may take into account, individually or in combination, when determining that Subpart F may apply.

What is the significance of a 'very small organisation' in the context of Subpart F applicability?

A very small organisation is one of the parameters that the competent authority may take into account when determining that Subpart F may apply, as it may indicate that a Quality System is not justified and/or feasible.

Does GM 21.A.124(b)(1)(i) specify any applicability date for the provisions it describes?

No, GM 21.A.124(b)(1)(i) does not specify any applicability date; it only references Decision 2012/020/R as the source.

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

Q: Under which circumstances may a competent authority issue a letter of agreement for production under Part 21 Subpart F instead of requiring Subpart G approval?

A letter of agreement for production under Part 21 Subpart F may be agreed by the competent authority when the applicant produces or intends to produce aeronautical products, parts and/or appliances intended for airborne use as part of a type-certificated product (excluding simulators, ground equipment and tools), and the competent authority determines that Part 21 Section A Subpart G would be inappropriate, consequently applying Subpart F.

Q: What is the main difference between Part 21 Section A Subpart G and Subpart F as described in GM 21.A.124(b)(1)(i)?

The main difference 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, whereas Subpart F does not require such a Quality System.

Q: In what situations may a Quality System, including independent monitoring and continuous internal evaluation functions, be considered not justified and/or feasible according to GM 21.A.124(b)(1)(i)?

A Quality System, including independent monitoring and continuous internal evaluation functions, may be considered not justified and/or feasible in situations where the competent authority determines that Subpart F may apply, taking into account parameters such as no flow production (infrequent or low volume of production), simple technology (enabling effective inspection phases during the manufacturing process), or very small organisation.

Q: Which parameters may a competent authority take into account, individually or in combination, when determining that Subpart F may apply instead of Subpart G?

The competent authority may take into account one or a combination of parameters such as: no flow production (infrequent or low volume of production), simple technology (enabling effective inspection phases during the manufacturing process), and very small organisation.

Q: According to GM 21.A.124(b)(1)(i), what is the purpose of the Quality System required under Subpart G?

The purpose of the Quality System required under Subpart G is to provide the competent authority with the necessary confidence to grant to the manufacturer the privileges of certifying its own production.

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.
