WebPerform static strength, durability, and damage tolerance analyses for specific or generic structural metallic repairs in support to the Commercial Aircraft fleet. Support the completion of various aircraft structural manuals such as Aircraft Structural Repair Publication and Aircraft Maintenance Publication. Manufacturers and operators of aircraft, trains, and civil engineering structures like bridges have a financial interest in ensuring that the inspection schedule is as cost-efficient as possible. In the example of aircraft, because these structures are often revenue producing, there is an opportunity cost associated with the maintenance of the aircraft (lost ticket revenue), in addition to the cost of maintenance itself. Thus, this maintenance is desired to be performed infrequently, even when …
