Variants and engines
Piper catalogs cover PA-18 Models 95, 105, 125, 135 and 150, and PA-18A (agricultural) Models 125, 135 and 150. The base PA-18 uses a Continental C-90 limited to 2475 RPM (90 hp). The 150 uses a Lycoming O-320 at 2700 RPM (150 hp). PA-18S models are seaplanes. PA-18A models have a hopper door and removable rear seat.
Structure and landing gear
The fuselage is welded steel tube, with some highly stressed members in 4130 chromemoly. Wings have aluminum spars and ribs, with lift struts adjustable at the forked fittings. The shock-cord gear needs only occasional greasing of hinge bolts and strut members, plus inspection of the steel hinge bolt bushings. Main tires are 8.00 x 4 at 18 psi.
What to inspect
The NZ CAA schedule dated 27 February 2025 lists these inspections: lift struts and forks, exhaust mufflers, fuel selector valve, lower fuselage attachment tab, and rudder post. It also lists control stick security, stabiliser adjustment screw, front landing gear fittings, and rudder pedal welds. Confirm compliance in the logbooks.
Summary written by AI from the source document. Check the original before relying on it. See which parts of Sprinkle are written by AI.
Safety notes
- Lift the airplane only at the extreme end of a lift strut, never mid-strut, to avoid bending it.
- Do not use the tail brace wires for lifting or handling. Use the handle on the right rear fuselage.
- Hopper-equipped aircraft: the AD notes undetected residual load can cause overloading with the CG beyond the aft limit.
