Description

BACKGROUND OF THE INVENTION

The present disclosure relates to a damage assessment system, and more specifically, to methods and systems for assessing allowable damage limits for a structure.

Maintenance programs intended to maintain structures in good operating condition may sometimes become complex and burdensome. By way of example, in operating airplanes in North America, Europe, Japan, Australia and in other regulatory jurisdictions which may have a bilateral agreement with the FAA (U.S. Federal Aviation Administration), airlines may need to manage a significant amount of complex and overlapping maintenance requirements set out by the FAA. Compliance with FAA and other requirements by an airline may be required to qualify an airplane for continued airworthiness.

As an aircraft ages or as repairs to the structure age, evaluation may be performed to verify the health of the structure and to confirm that the structure has sufficient remaining strength for continued operations. Structural damage data needs to be interpreted in order to assess the health of a structure. Some known maintenance programs require that personnel interpret this data. Errors can arise due to manual collection and interpretation of the data, leading to errors in assessment of the health of a structure. Variability exists when data of structural components is interpreted manually. For any given structural inspection task, the probability of detection can be affected by several factors such as the skill and experience of the inspector; accessibility to the structure; and exposure of the inspection surface.

Moreover, some known programs for assessing allowable damage limits include field personnel looking up data in structural repair manuals. The assessment, however, can require that the personnel sift through large amounts of data to attempt to locate critical allowance data which is time consuming and inefficient. To successfully manage such a maintenance program, structural and maintenance personnel may need to have a comprehensive and detailed understanding of all the requirements of the maintenance program and of the 3D (three-dimensional) physical locations on structure where the requirements may apply. A program to systematically locate, identify, quantify and/or assess structure damage would enhance better utilization of maintenance programs.

The processor is further configured to perform a structural analysis to determine a damage allowability based on the at least one parameter and display a maintenance instruction based on the damage allowability.

In a further aspect, a computer-implemented method of performing maintenance on a damage of a structure is provided.
