MCM Engineering recommends annual 400Hz Ground Power System Evaluation Service. The service consists of an MCM factory trained Field Service Specialist (FSS) inspecting and testing all equipment and components comprising the 400Hz ground power generation system.

A complete load testing of the system is performed utilizing MCM Engineering 400Hz resistive and reactive load banks in series to replicate actual loads produced by aircraft.

400HZ AIRCRAFT CABLE REPAIR SERVICE

MCM Engineering also offers 400Hz Aircraft Cable Repair Service to extend the life of our customer’s cables with considerable cost savings, customers can send their used non-operational cables to the MCM Factory Facility where a thorough diagnostic test is performed to determine if the cable can be repaired. If the cable is repairable; a new connector head will be molded on to the original cable. 

MCM Engineering can repair the vast majority of aircraft cables for roughly 1/3 of the original cost. This is accomplished by molding our connector on to the cable of any aircraft cable manufacturer.

Below is an example of an unserviceable connector head that was removed and replaced with a new connector attached and molded on to the original cable. 

* All aircraft cables with newly molded connector heads include replaceable base, pins and Gold-X Nose cover (optional).

Before: Damaged unserviceable connector head

After: New molded connector head with replaceable base, pins & Gold-X Nose cover.
