Service Difficulty Advisory

AV 2008-06
15 August 2008

TELEDYNE CONTINENTAL
ENGINE MODEL A-65 SERIES

This Advisory is issued to inform the aviation community of the possibility of an ineligible engine model that may be installed in aircraft operating under a standard Certificate of Airworthiness pursuant to Canadian Aviation Regulations (CAR) 507.02. This information is not relevant to aircraft operated under a special certificate of airworthiness in the owner-maintenance or amateur-built classification.

The Teledyne Continental Engine Model series A-65 is certified in accordance with the Federal Aviation Administration (FAA) Type Certificate Data Sheet (TCDS) No. E-205, Revision 16, dated 1 November 1973. A copy of the TCDS can be reviewed at the following web site: http://www.airweb.faa.gov/

Aircraft manufacturers such as Aeronca, Luscombe, Piper and Taylorcraft, have Teledyne Continental Engine Models installed on certain models of their aircraft. Note 6, of FAA TCDS E-205, is of particular interest to owners of these aircraft models.

Note 6 is quoted below for your convenience.

Note 6: Approval for Models A-65-1, -3, -6, -6J, -7 and –7J expired November 17, 1941. No engines of these models manufactured after that date or with S/N’s above the following, are eligible for use in certificated aircraft:

Models Serial No.
A-65-1 379991
A-65-3 387593
A-65-6 389096
A-65-6J 373296
A-65-7 575897

Any type-certificated aircraft having an installed engine, which meets the criteria of Note 6, does not meet the aircraft’s certified type design and therefore is not eligible for the issuance of a standard Certificate of Airworthiness in accordance with CAR 507.

To ensure the Certificate of Airworthiness remains valid, Transport Canada recommends those affected aircraft owners review their aircraft documentation to ensure the affected engine models are not installed in their aircraft.

For further information, contact a Transport Canada Centre, or call Marcel Gauthier, Continuing Airworthiness, Ottawa. Telephone 613-952-4364, or facsimile 613-996-9178, or e-mail gauthmr@tc.gc.ca.
