Aircraft Wire Management System

Your aircraft wiring design, maintenance, and associated costs may range from a minor to a major factor.

Your aircraft wiring system's maintenance can be simplified and costs can be reduced when an appropriate wire management plan is implemented. Lectromec has seen the wiring failure rate reduced by a factor of eight when thoughtful review and changes in procedures for Electrical Wire Interconnect System (EWIS) activities were implemented. Studies have shown that unscheduled maintenance can be as high as two hours for every flight hour, with a large percentage of maintenance directed toward wiring or wire system components.

Some groups that may see a benefit in the implementation of an Aircraft Wire Maintenance Program include:

• Maintenance and repair operation (MRO) facilities that affect safety
• Original equipment manufacturers (OEMs)
• Designated engineering representatives (DERs) who freelance and support all others on this list
• Designated Airworthiness Representatives—for manufacturing conformance
• Line Replaceable Unit (LRU) developers
• Inspectors of used aircraft that are being sold or whose ownership is being transferred
• Leasers of aircraft needing to ensure that their rights are being properly maintained by the leaseholders so as to not jeopardize the equity in the lease
• Operators of aircraft needing to protect against EWIS-related problems such as:
  • Lack of availability of equipment due to unscheduled defects, resulting in loss of revenue
  • Loss of equipment or aircraft due to EWIS failure-induced physical damage
  • Need for overly extensive maintenance work force or maintenance contract with an outsource company

The aircraft wire maintenance solutions are customer specific and are designed by Lectromec to maximize the maintenance program's effectiveness.

Non-Aerospace Platforms

Though originally designed by Lectromec for application to aerospace platforms, the Aircraft Wire Maintenance Program can be applied to any platform or system that requires knowledge of the current wire status and, if necessary, a targeted replacement plan.

For non-aerospace applications, wire system evaluations address wire system assessment needs by combining component degradation, probability of failure, and failure severity. This assessment recognizes the uniqueness of each system, whose failure consequences differ from those of other systems.

The comprehensive approach addresses even the most complex situations including non-uniformity of environmental conditions or the complexity of older systems that have been modified numerous times and whose wire system components are of different types and ages.

Lectromec has developed the skills and tools necessary to address the needs and special requirements of both aerospace and non-aerospace wiring systems.
