Chapter 549 - Amateur-Built Aircraft - 549.9 Powerplant

(a) The Powerplant may utilise propeller or reaction jet propulsion, but not solid and liquid fuel rockets. Installations are not restricted to approved aircraft engines. Type-approved engines shall be operated within all established certification limits. For non-type-approved engines, limits must be established by the applicant.

(b) For propeller driven propulsion systems:

(1) Acceptable engines include, but are not limited to, conventional 2 or 4 cycle piston engines, Wankel engines, gas turbines and other unconventional internal combustion engines.

(2) For the purpose of this Chapter, Wankel engines are treated as reciprocating engines.

(c) For reaction jet propulsion systems: Engines commonly referred to as turbojets and turbofans are acceptable.

(d) For engines incorporating turbomachinery (e.g. turbocharger), rotating shaft speed limits shall be established by the applicant and:

(1) There shall be means to prevent such limits being exceeded; or

(2) It must be shown that in the event of a failure, no hazardous debris will be released following a mechanical failure at the highest shaft speed possible.
