MECSIP

Integrating EWIS into Fleet Sustainment and MECSIP

While the Electrical Wiring Interconnection System (EWIS) evaluations and sustainment requirements have been part of the Mechanical Equipment and Subsystems Integrity Program (MECSIP) since 2013, it is only just recently that EWIS elements are part of performance measurements. This webinar, presented by Lectromec, provides an excellent opportunity to improve your understanding of EWIS, EWIS requirements, and highlights a path for better and more cost-effective EWIS evaluation.

Selection of Zones for Degradation Testing

Maintenance zones within an aircraft are not homogeneous. They vary from the extreme Aircraft areas within the aircraft (engines) to more benign areas (inside pressure and temperature-controlled areas). And because of this, the components within each of these zones will age at different rates. Naturally, different components are selected for each of these zones; those components better able to handle the severe environments are installed in those environments, and lower requirements are placed on those parts installed in benign environments.

Consequences of EWIS Implementation

In June 2019, Lectromec was asked to present at the USAF Mechanical Equipment and Subsystems Integrity Program (MESCIP) conference. With the electrical wiring interconnect system (EWIS) working its way into fleet sustainment activities, fleets now must take and apply the EWIS lessons learned.

Since the commercial segment has been subject to the 25.17XX EWIS regulations for more than a decade, the presentation examined the intended and unintended consequences of these regulations. For those seeking to integrate EWIS concepts into their fleet maintenance practices, this presentation gives an overview of the factors to be considered for your fleet.

Condition Based Maintenance and Risk Quantification

Aircraft maintenance is usually broken down one of two ways: by physical zones or by systems. The mechanical equipment and subsystems integrity program, also known as MECSIP, is the US Air Force’s approach to addressing aircraft sustainment and maintenance through focused system evaluation. Last week, MECSIP managers from many of the Air Force fleets gathered in Dayton, Ohio to discuss the latest developments, procedures, and technologies for addressing the MECSIP needs of their fleets.

Getting the Most Value from Wire System Degradation Assessments

Task four of military handbook MIL-HDBK-525 (also incorporated into the mechanical subsystems integrity program standard MIL-STD-1798) outlines a set of considerations and procedures for the assessment of an aircraft electrical system specifically for the service life extension program (SLEP). The important factor is to ensure that resources are not wasted on this effort and that […] Read more
