As part of a project in 2002, three trolleys were designed to 'handle' the jet engine of the Light Combat Aircraft during Installation/ Removal, Storage and Maintenance operations. The primary design challenge was to be able to transfer the jet engine from one trolley to the other without needing to use a Gantry crane - an ability that is invaluable in operations as it allows the support crew to service aircraft anywhere on the airfield, instead of having to first bring it into the maintenance hangar. As part of the indigenization of support equipment, the trolleys were designed so that they could easily be fabricated in the airfield workshop and be field serviced anywhere on the airfield, thereby obviating the need to first bring them back to the hangar.
