Add aging systems tasks to the aging airplane research program The FAA will prepare Research Project Descriptions to initiate the process to obtain funding for the following research needs. A. Determine if a service life for airplane wire is appropriate. Based solely on visual inspections, the integrity of aging airplane wire appears adequate. However, some isolated deterioration was noted in the outermost insulation layers in all three airplane models examined.
Research is needed to determine if a service life for wire is appropriate and needed.
Provide the Standards Management Team with prioritized research needs. Laboratory analysis of aged wire will establish if problems, not evident by the visual inspection, are evident in the various wire insulation layers. Provide the Standards Management Team with prioritized research needs. Under current maintenance inspection practices, wire is inspected visually. Inspection of individual wires in bundles and connectors is not practical because aged wire is stiff and dismantling of bundles and connectors may introduce safety hazards.
