Abstract: In a particular embodiment, a trailer is disclosed that includes a base, a frame extending from the base, and mounting structures coupled to the frame. The mounting structures are adapted to releasably secure an engine, such as an aircraft engine, to the frame such that the engine is secured to the frame and suspended above the base without contacting the base.

Abstract: A method of determining a preferred order of implementing maintenance tasks and determining a plurality of maintenance tasks related to a received maintenance request is disclosed. A first expected cost of implementing the plurality of maintenance tasks in a first order and a second expected cost of implementing the plurality of maintenance tasks in a second order are determined. An implementation order for the plurality of maintenance tasks is selected based at least in part on the first and second expected costs. Expected costs may be determined based at least in part on the cost of implementing each maintenance task and based on the probability that the problem has not yet been addressed by preceding tasks.

Abstract: A method is provided that includes receiving a primary work scope comprising a set of tasks associated with maintenance of the mechanical system including a life-limited part. The method further includes generating a set of work scopes for the mechanical system, where each work scope of the set of work scopes includes the primary work scope and at least one additional task associated with maintenance of the mechanical system. At least one work scope of the set of work scopes includes a maintenance task related to the life-limited part. The method further includes estimating an operating time and a cost performance parameter for the mechanical system based on each work scope of the set of work scopes and providing an enhanced work scope. The enhanced work scope has an operating time that is greater than a threshold.

Abstract: A treatment apparatus includes a vacuum chamber to receive a backfill gas, a support to receive a work piece, a filament located within the vacuum chamber, and an anode located within the vacuum chamber. The support is located within the vacuum chamber.

Abstract: This disclosure is directed to a method to enhance cost performance of a mechanical system. The method includes inspecting the mechanical system to determine a primary work scope. The primary work scope is associated with a first subset of the set of modules. The method further includes accessing a computational system configured to determine an enhanced work scope associated with the first subset and a second subset of modules. The enhanced work scope is determined based on expected cost per unit operation time of the mechanical system. The method also includes performing tasks associated with the enhanced work scope on the mechanical system.
