Abstract
Inspection and repair of an air cushion vehicle flexible skirt is carried out with the vehicle supported above a ground surface on support legs projecting from sleeve members built into rigid base structure of the vehicle so as to be open between upper and lower surfaces of the base structure. The vehicle lift system is used to hover the vehicle clear of the ground so that the support legs can be secured in their projecting positions. Alternatively, jacks may be supported over the sleeves and used to force the support legs down the sleeve members to their projecting positions. The vehicle may be further raised above the ground surface to permit inspection and repair of the underside of the rigid base structure by first replacing each support leg with a support stand and pillar assembly and then using the jacks to raise the vehicle with the support legs resting on the pillars.
