(12, Service Difficulties. A totally integrated quality contro system would include the means of recording, investigating cause, and assuring corrective action on all known or reported failures, malfunctions, and defects, including procedures, as applicable to each particular mamufacturer, to ensure that:

(a) Service problems are investigated and prompt corrective action is taken on all affected products as appropriate.

(b) Users of the product are informed of service difficulties and resultant FAA-approved changes to the type design in accordance with FAR 21.99 requirements.

(c) Feedback on service problems is received from users of the products to the extent practicable.

(d) Requirements of FAR 21.3 and FAR 37.17 relative to the reporting of certain malfunctions and defects are satisfied.

10. FAR 21,147 - CHANGES IN THE QUALITY CONTROL SYSTEM.

a. An acceptable means of compliance with the notification requirements of this regulation is to notify the district office of changes falling within the scope of the regulation.

c. A change in suppliers or in the delegations of quality functions to suppliers may or may not result in changes to the production certificate holders approved quality control data and system. When it does, FAR 21.147 requires the holder to immediately notify the FAA in writing, of any change which may affect the inspection, conformity, or airworthiness of the product, and in order to comply with FAR 21.

165(a), an FAA evaluation and approval will be necessary under FAR 21.143(a). When it does not, FAR 21.143(b) requires merely that information regarding such changes or delegations be made available to the FAA. For the foregoing reasops, an applicant for, or holder of, a production certificate is advised to submit quality control data which fully describes the controls which he will use to establish and control all supplier furnished articles or services, including general information on any type certificate or production certificate data, purchase orders, procurement specifications, etc., with which the supplier must comply.

11. FAR 21.151-PRODUCTION LIMITATION RECORD. The production certificate may not always authorize production of every model listed on the type provided by the regulations for denoting each specific product; therecate, each model authorized for manufacture under the production certificate, and the date of such authorization.

12. FAR 21.153-AMENDMENT OF THE PRODUCTION CERTIFICATE.

a. Application to amend a production certificate is made in the same form and manner as the original issue, except that only changes to the existing quality control data need be submitted, when production of the new product involves changes in the quality control system.

If no changes in the quality control data are required, the situation should be documented by letter to the district office.

b. Since a production certificate may be amended ior several dizierent purposes, the following paragraphs provide, examples as to methods applicable in differing circumstances:

(1) The holder of a production certificate may make application to add a new type certificate, new model, or a supplemental type certificate (STC) to his production certificate. Upon evaluation and approval of the quality control data and manufacturing facilities, as applicable, the FA will issue a superseding production limitation record, which automatically cancels the existing one, except that STCs which are referenced in, and become a part of the approved type design data, will not be listed on the production limitation record.

Page 15OCROpen in PDF

When production of completed products as well as spare articles nas ceased, the holder or a production certificate should request deletion of the applicable type certificate from his production limitation record by a letter to the regional office. A revised production limitation record will be issued, and the superseded production limitation record would be cancelled.

(3) If the holder of a production certificate ceases to manufacture complete products, but continues to manufacture spare articles, his production limitation record does not require

13. FAR 21,157-INSPECTION AND TEST. Following the issuance of the production certificate, the FAA will maintain periodic surveillance of the production facilities and quality control system, by the use of a Quality Assurance Systems Analysis Review (QASAR) program. The QASAR program is a systems analysis by an inspection team of the manufacturer's complete quality control system. If an inspection or test conducted by such an inspection team discloses that any part of the data or system which was originally approved does not fully meet the applicable requirements, the FAA will request changes to the quality control system or data as may be required.

a. The FAA considers any evidence of inspection approval placed on inspection records, test reports, or physical articles as documentation that the article, process, or manufacturing operation has been accepted by the holder of a production certificate.

b. If an article has passed through a point officially designated for inspection, the omission of any required stamps or signatures, which were designated to be applied at that point to the physical articles, inspection records, or test reports, may be considered as noncompliance with approved quality control data and procedures.

FAR 21 161-DISPLAY. The production limitation record is part of and should be displayed with the production certificate. The holder of a production certificate may make copies of the production certificate and production limitation record for display in offices of outlying plants which are part of the main manufacturing facilities.

15. FAR 21,163-PRIVILEGES. The holder of a production certificate may:

•. Obtain airworthiness certificates and related approvals without further showing, except that the FAA may inspect products for conformity with the type design.

b. Obtain the appointment of individuals in his employ as Designated Manufacturing Inspection Representatives (DMIR) for: the purpose f issuing airworthiness certificates and related approvals.

(Ref. FAR, Part 183).

c. Apply for Delegation Option Authorization (DOA), if the product he is producing qualifies under FAR 21.231.

16. FAR 21.165-RESPONSIBILITY OF THE HOLDER.

a. The holder of a production certificate has a basic responsibility for controlling the manufacture of completed products and spare articles in conformity with his FAA-approved quality control data and type design requirements. Although this responsibility never changes, he may be relieved of some of the burden of inspection and testing duties when he:

(1) Uses other type certificated product or products manufactured under another person's production certificate, or which bear an FAA Airworthiness Approval Tag, FAA Form 8130-3.

(2) Uses articles produced under an FAA ISO authorization.

(3) Installs used articles that conform to the type design.

(4) Uses articles fabricated under an FAA Parts Manufacturing Approval.

(5) Delegates specific inspection and testing duties to suppliers.

(a) The hol eno (a) The holder of a production certificate may be relieved of some of the burden of inspection and testing when these functions are delegated to a supplier. However, the production certificate holder remains responsible for controlling the design, physical configuration, operating condition of the articles of products furnished by such a supplier. All changes made by a supplier, to the design or the physical product or article, must be submitted to the holder of the production certificate for evaluation and approval as applicable under FAR 21, Subpart D. Thus, che note of the holder of a production certificate is responsible for obtaining FAA approval of materials review actions or other design changes including those made to supplier furnished articles which were not designed or manufactured by bim and would also result in a change to his type design data or to his products.

(b) A supplier who holds an FAA production approval, PC, APIS, PMA, TSOA, or FAA Repair Station Certificate 18 also responsible when articles or services furnished by him, to the production approval holder:

Do not conform to his (the supplier's) FAt approved design data;

2 Were not manufactured or overhauled in accordance with the supplier's PAl-approved quality control data or repair station inspection procedures manual;

OT 3 Contain any defects which normally would not be found by the manufacturer in conducting his receiving inspections and functional tests and which would result in an unsafe product.
