PARTS MANUFACTURING APPROVAL (PMA) REPLACEMENT PART USE ON CANADIAN AIRCRAFT

 Purpose

The purpose of this notice is to apprise all concerned of the exemption issued to provide interim relief to owners of aircraft where replacement parts are available through a Parts Manufacturing Approval (PMA) issued by the Federal Aviation Administration (FAA), pending the implementation of pertinent changes in the Aircraft Equipment and Maintenance Standards and the Canadian Aviation Regulations (CARs).

The exemption, subject to the related Schedule of Conditions, frees the owners from the restrictions on the use of PMA replacement parts required by subsection 571.07 (c) to (h) of the Aircraft Equipment and Maintenance Standards made pursuant to subsection 571.07 of the CARs.

 Background

The recent FAA/TCCA Bilateral Aviation Safety Agreement (BASA) Implementation Procedures (IPA) for Design Approval, Production Activities, Export Airworthiness Approval, Post Design Approval Activities, and Technical Assistance Between Authorities signed in October 2000, introduced a new reciprocal agreement for acceptance of replacement parts intended for installation on aeronautical products. 

The FAA agreed to accept replacement parts approved under a new TCCA “Part Design Approval” (PDA) and produced under a TCCA manufacturer’s certificate for installation on U.S. registered aircraft or on other aeronautical products to be installed thereon.  In return, TCCA agreed to remove the existing limitation in Standard 571 on FAA Parts Manufacturer Approval (FAA PMA) replacement parts usage on Canadian registered aircraft or on other aeronautical products to be installed thereon.

Aircraft Maintenance and Manufacturing issued an exemption to allow the implementation of the Notice of Proposed Amendment (NPA) 2001-030 and NPA 2001-034 policy in order to provide installers of parts on Canadian registered aircraft with additional acceptable sources of supply.   This would allow for an improved level of service to the public, from Canadian Operators.

Note:  

Issuance of an FAA PMA has two purposes:  (1) it is both a design and a production approval when used for a replacement part, or (2) it is strictly a production approval when used for a modification part as used in a Supplementary Type Certificate (STC).  The subject of this exemption is replacement parts.

Modification parts receive design and installation approval through issue of an FAA STC.  To obtain production approval for modification parts the applicant must obtain an FAA PMA.  These modification parts, which are PMA’d for production purposes only, are not covered by this exemption.  However, modification parts approved by FAA STC may be used following the STC procedures presented in the BASA Implementation Procedures and Aircraft Certification Staff Instruction (ACSI) No. 23.

The existing text of Standard 571.07(c) to (h) allows for the installation of FAA PMA parts on Canadian registered aircraft under certain specific conditions.  Since these restrictions are no longer required due to the changes in the recent BASA IPA with the FAA, most of this section of Standard 571.07 will be deleted. 

NPA 2001-030 to CAR 571.07 and NPA 2001-034 to Standard 571.07 which permit the installation of FAA PMA parts consistent with the BASA implementation agreement, were accepted with a few editorial changes at the June 2001 CARAC Part V Technical Committee meeting.

Aircraft Maintenance and Manufacturing is issuing the exemption for the period of time required for the implementation of NPA 2001-030 and NPA 2001-034 policy.  This Airworthiness Notice is issued as an interim measure, and will be canceled upon publication of the formal amendment to the Aircraft Equipment and Maintenance Standards.
