Compliance Is Not Retroactive, And Dependent On Specific
Installation Instructions
Rotax has completed compliance with the ASTM F2339 standards for
the Type 503 engine, which was no small task given the age of the
design and the complexity of the standard. The basic engine design
is from the late 1970s, first produced in one version for
snowmobiles starting in 1979. The engine's original testing
was done to a very different level, and all the original
verification had to be completed, repeated, and supplemented with
the latest requirements.
Rotax 503 Engine
Testing for durability had to be repeated. Even though the
reliability of the engine has been very high, it had to meet the
latest testing and requirements under ASTM. Rotax took this
up at the request of the distributor for the Americas to show
support for the smaller OEM who would like to work with the engine
in SLSA compliance.
The only caveat is that the compliance is not retroactive. It
applies to only the serial ranges of the latest production runs.
Compliance is also dependent on following the installation,
maintenance and service information for the engine that comes from
Rotax.
Engines with serial number 6479168 and higher are ASTM
compliant. A written compliance statement (example below) is
available for each engine on request.
BRP-Powertrain GmbH & Co KG hereby declares that the
aircraft engine or part of thereof as described in the statement of
compliance conforms to the applicable ASTM 2339-06 ( Reapproved
2009 ). No features or characteristics are found which would make
the engine unsafe provided it is installed, operated and maintained
in accordance with instructions and limitations as defined by
BRP-Powertrain GmbH & Co KG approved documentation.
The engine S/N mentioned above also complies to the ASTM
standard provided it is installed, operated and maintained in
accordance with instructions and limitations as defined by
BRP-Powertrain GmbH & Co KG approved documentation and is not
modified.
The product complies with the ASTM 2339-06 ( Reapproved 2009
) regarding our quality system for record keeping and instructions
for continued airworthiness.
