ABSTRACT:
The method and apparatus for conducting inspections and maintenance activities of this invention reduce the time required to conduct inspections and perform maintenance upon the aircraft structure and various systems, such as electrical and hydraulic, contained within the confined space located beneath the main deck of an aircraft by providing ease of movement for the individual and his tools. Additionally, this invention reduces the hazards associated with movement through the confined space and bulkheads under the main deck of an aircraft. The inspection and maintenance apparatus of this invention includes a trolley of proper size for a person and tools mounted upon parallel rails which are contained and extend longitudinally within the confined space under the main deck of an aircraft. The trolley is placed upon the rails at mounting points which are located under access panels in the main deck of the aircraft. The trolley is then moved longitudinally along the rails carrying the individual inspector or mechanic with his tools to the appropriate location under the main deck of the aircraft. When not in use, the trolley may be removed from the aircraft for storage thereby reducing aircraft weight.
