Dan Hopper 1/19/2005 Hello Dan, FAR Sec. 21.303 says "....no person may produce a modification or replacement part for sale for installation on a type certificated product unless it is produced pursuant to a Parts Manufacturer Approval issued under this subpart." I would suspect that the person producing these starters does not have PMA for them so in order to avoid violating FAR Sec. 21.303 he says they are strictly for airboats. The regulations preventing people from installing these starters on type certificated aircraft are a little more indistinct or unknown and a person could install one on a type certificated aircraft either out of ignorance of the regulations or outright flouting of the regulations.** There is no regulation that would prevent a person from using such a starter on an amateur built experimental aircraft. OC **PS: What FAR prevents the installation of non approved parts in type certificated aircraft? The closest that I can come to such a prohibition is FAR Sec 43.13 (b) which says "Each person maintaining or altering, or performing preventive maintenance, shall do that work in such a manner and use materials of such a quality, that the condition of the aircraft, airframe, aircraft engine, propeller, or appliance worked on will be at least equal to its original or properly altered condition with regard to aerodynamic function, structural strength, resistance to vibration and deterioration, and other qualities affecting airworthiness." -- No virus found in this outgoing message.
