## Summary of Proposals

- Part 21, Subpart A Continued
- “Replacement and modification parts” relocated here.
- “Approval of [articles]” relocated here.

**Notes:**
Summary of Proposals, Part 21, Subpart A  

Replacement & Modification Parts /Approval of [articles] ... 

This proposal relocates § 21.303(a) & (b) “Replacement and modification parts” and § 21.305 “Approval of materials, parts, processes, and TSO articles” [from Subpart K] to this Subpart ... since the requirements of these sections are more appropriate in a General Section of Part 21. 

Note: The term “article” is used on this slide to highlight the advantage of using this new definition when referring to “materials, parts, processes and appliances.” 

-	This proposal also intends to modify § 21.9 so that the proposed rule does not interfere with replacement and modification parts for military surplus aircraft ... [Note: This is an AIR-100 proposed change that is not completely developed yet. Therefore, this proposal may be moved to Phase II Rulemaking]. 

## Summary of Proposals

- Part 21, Subpart E
- PCs for STCs
- Eliminated a conflict w/ U.S. Statute.
- FAA will consider granting STC Holders a Production Certificate.

**Notes:**
Summary of Proposals, Part 21, Subpart E  

PCs for STCs ...
§ 21.119  Privileges. 
The holder of a supplemental type certificate may—
(c) Obtain a production certificate in accordance with the requirements of subpart G of this part for the change in the type design approved by that supplemental type certificate.

Section 21.119  Privileges.  [Preamble] 

-  This proposal would revise §21.119(c) to clarify that the holder of an STC may obtain a production certificate for the change in the type design approved by the STC only if the STC holder meets the requirements of subpart G pertaining to the issuance of PCs.  The FAA plans to issue guidance material concurrent with the final rule aimed at ensuring that any PCs issued meet the requirements of subpart G.  In accordance with 49 U.S.C. 44704(c), the FAA may include in a PC terms required in the interest of safety.  These terms may limit the scope of activities authorized by the PC depending on the STC holder’s quality system and the complexity of the design changes approved by the STC.

-  However, the FAA will consider revising its policy regarding those circumstances that the FAA would consider granting the holder of an STC an appropriate production approval.
