Estimates of POD/PFA for ET inspection Milestones: improvements made with ETC tools.
Updates to default POD curves for RISC documents.
Prototype software suitable for implementation of the methodology by the OEMs.
Metrics:
The methodology developed for estimating POD of eddy current inspections will be judged
successful if three conditions are met. For data sets such as those used by existent
methodologies, the new methodology should make comparable POD predictions. For sparse data
sets, the new methodology should make sensible predictions when none are made by existents
empirical methodologies. In either case these predictions should be able to be obtained with less
expense and more rapidly than with existent methodologies.
The updates to the POD curves will be judged successful if they are incorporated by RISC in life
management guideline materials.
The software produced to implement the methodology will be judged successful if it is utilized by
the members of ETC and the Rotor Integrity Subcommittee of AIA in life management decisions.
The estimates of improvements afforded by the advances in the ETC will be judged successful if
they impact the acceptance of these technologies by the OEMs.
