Abstract
An airplane jack to lift a light airplane nose wheel off the ground by the nose wheel fork to allow maintenance. The jack uses a lever to manually pivot on rollers to lift the nose wheel fork by non-marring cradling supports. A sliding lever provides unencumbered wheel access and extra safety against any possible pivoting of the jack by repositioning the lever. The jack's width can be adjusted to work with a plurality of nose wheel forks and varied in size and material to operate with a plurality of airplanes.
