distribution, assuming an exponential (2" of freedom) distribution even though the failure rate for the test time is zero.
6.7.5 Landing gear (axle) jack(s). Landing gear (axle) jacks titled as axle or landing gear are specifically designed to lift by hydraulic power the landing gear or the axle to facilitate a normal maintenace function. If the jack is light weight and is capable of being hand carried it is so defined,
but for the heavier axle jacks built-in wheels or casters are provided as well as a tow bar. These jacks are dolly mounted. All of these features are designed for ease of emplacement and mobility. For the convenience of tire removal certain axle jacks may have extension arms and additional external supporting or stabilizing members.
6.7.6 Airframe (tripod) jack(s). Ainframe (tripod) jacks are designed with three legs for full support and maximum stability These legs die either fixed in length or by adding extensions their initial height may be varied hence the characteristic, variable height. These jacks are hydraulic powered and are used to lift the aircraft by its wing or fuselage.
6.7.7 Airframe (Unipod) jack(s). Airframe (Unipod) jacks are designed with one leg which can be used to support the aircraft under its tall.
6.7.8 Rated capacity. The rated capacity or load is that load or Combination of forces that the hydraulic aircraft jack shall support or resist while in a static condition.
