Airwothiness Notices - B034, Edition 3 - 13 February 1998
Certification of Pressure Vessels Canada - U.S.
Bilateral
(This
notice supersedes AN No. B034 Edition 2, dated 28 November 1996)
Purpose
This
notice is to inform interested parties that the bilateral airworthiness
agreement between Canada and the United States does not cover the hydrostatic
testing of aircraft pressure vessels. Consequently,
until a bilateral accord can be reached that includes the mutual recognition of
test facilities, a unique system of regulation is required.
This AN identifies the procedures and standards for approval to perform
this work in Canada and in the United States.
Background
Transport
Canada is negotiating with the U.S. Federal Aviation Administration for
agreement on the mutual recognition of Canadian and U.S. approvals for pressure
vessel testing. However, until
agreement can be reached whereby either country can test and certify pressure
vessels for installation in the other nation’s aircraft, pressure vessels
intended for use in U.S. registered aircraft must be tested in accordance with
U.S. requirements, while pressure vessels intended for use in Canadian
registered aircraft must be tested in accordance with Canadian requirements.
Standards
for Approved Organizations
Organizations
engaged in the hydrostatic testing and internal inspection of pressure vessels
(including those organizations that already hold approved organization
certificates issued pursuant to CAR 573) must also be approved by the Transport
Canada Dangerous Goods Directorate at the address listed below.
The standards to be referred to are:
-
Canadian Standards Association
CSA-B340-97, “Selection
and Use of Cylinders, Spheres, Tubes and Other Containers for the Transportation
of Dangerous Goods, Class 2”;
-
National Standard of Canada
CAN/CSA-B339-96, “Cylinders, Spheres and Tubes for the Transportation of
Dangerous Goods”;
-
United States, Federal Aviation
Administration, FAA Order 8000.4D, “Maintenance of Pressure Cylinders in Use
as Aircraft Equipment”; and
-
United States, Code of Federal
Regulations, Title 49 ss173.34, “Qualification, Maintenance and Use of
Cylinders”, and referred parts, sections or subsections.
Application
for Approval
Application
for approval should be made to:
Transport Canada, Safety and Security
Dangerous Goods Directorate
Attention: Director ASDD
Place de Ville, Tower C
330 Sparks Street, 9th Floor
Ottawa ON K1A 0N5
American companies that can meet the applicable criteria may also apply for approval by
the same process.
Requirement for Canadian companies to register in the United States
Canadian companies wishing to carry out testing of aircraft cylinders for use in U.S.
registered aircraft are required to obtain U.S. DOT approval and, if eligible,
to test cylinders in accordance with U.S. DOT recommended standards.
Approval can be obtained through application to:
Chief, Approvals Branch (DHM-32)
Office of Hazardous Materials Safety
Department of Transportation
Washington, D.C. 20590
For Minister of Transport
D.B. Sherritt
Director, Aircraft Maintenance
and Manufacturing
