(Practice)Standard Practice for Design and Manufacture of Reciprocating Spark Ignition Engines for Light Sport Aircraft
Standard Practice for Design and Manufacture of Reciprocating Spark Ignition Engines for Light Sport Aircraft
SIGNIFICANCE AND USE
This practice provides designers and manufacturers of engines for light sport aircraft design references and criteria to use in designing and manufacturing engines.
Declaration of compliance is based on testing and documentation during the design and testing or flight testing of the engine type by the manufacturer or under the manufacturers' guidance.
SCOPE
1.1 This practice covers minimum requirements for the design and manufacture of reciprocating spark ignition engines for light sport aircraft, VFR use.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
