Control and switch names may not match the actual aircraft. Do not fly behind this file. Airspeeds, RPM figures and temperature limits are illustrative placeholders, not limitations. The speeds block is deliberately omitted rather than populated with invented numbers. Aircraft in this class vary substantially between individual builds. A file that is correct for one Aerolite 103 may be wrong for the next; airframe-specific variants will be needed.

This aircraft is operated as an ultralight vehicle under 14 CFR Part 103. It has no airworthiness certificate and no N-number, and the pilot needs no certificate or medical. Single occupant only Day, visual conditions only Not over congested areas or open-air assemblies of people Not in Class A, B, C or D airspace without prior ATC authorization Part 103 imposes no maintenance or inspection requirement. Nobody else is checking this aircraft. The preflight is the entire inspection programme.

A two-stroke can fire on a single blade movement with the ignition off if a switch or ground lead has failed. Keep the propeller arc clear and never stand in it. Propeller blades and bolts NO NICKS OR CRACKS, TORQUE MARKS ALIGNED Engine mount and rubber isolators SECURE, NO CRACKS Exhaust system and springs SECURE, NOT CRACKED Fuel lines and primer bulb NO CHAFING, NO WEEPING Fuel quantity and mix CHECKED, CORRECT OIL RATIO Confirm the premix ratio against the engine manufacturer's figure for this engine and oil. Running a two-stroke on straight fuel will seize it. Fuel sample CLEAR, NO WATER

A single-cylinder two-stroke should be treated as an engine that will stop without warning. Do not depart over terrain that offers no landing option.

Do not attempt to turn back to the runway. At this aircraft's altitude, speed and glide performance a turn back will stall it.
