This invention is directed to a multipurpose repair and maintenance apparatus for aerial inspection, repair and cleaning, comprising a work platform for installation on the skids of an helicopter and sustaining a boom assembly and a fluid circuit such that the loads on the work platform are fully balanced. The work platform is made of electrically conductive material and all electrically conductive parts of the apparatus are connected to the electrically conductive parts of the helicopter to have same electrical potential. The boom assembly extends from the port side of the work platform and has an inboard section and an outboard section. A pumping assembly is mounted on a power drive mount at the starboard side of the platform, so as to balance the weight of the boom assembly. A boom actuator is provided at the onboard end of the boom assembly and controls the vertical and horizontal movement of the outboard end. The fluid circuit includes the pumping assembly and fluid conduits guided along the boom assembly for spraying cleaning fluid from a fluid storage tank through a nozzle located at the outboard end of the boom assembly. The orientation of the nozzle is controlled with a nozzle control arm. When the work platform is used for inspection or repair, the boom assembly is removed and a wing is attached to the portside. Now, the weight of the inspector/repairman at the portside is balanced by the weight of the power drive mount at the starboard side. In addition, the length of the starboard side of the work platform and the port side is also selected so that the loads are balanced.
