The MMG-1A is a small, compact, trailer-mounted, electric motor-driven generator set (MEPP-Mobile Electric Power Plant). It provides 60 KVA of power under 115/200-volt, 3-phase, 400-hertz AC, and 500/1,000-ampere 28-volt DC power for aircraft maintenance, calibration, and support. Operation of the unit requires a 3-phase, 60-hertz, 220- or 440-volt external power source. The 30-foot input and output cables are stowed in compartments in the rear and left front side of the unit. It was used by the U.S. Navy both aboard ships (including aircraft carriers) and ashore. The MEPP is not self-propelled and must be towed or manually moved. The 4-wheel trailer is equipped with tie-down rings, pneumatic tires, a mechanical hand brake, and a tow bar for towing and steering.
The QAM’s MMG-1A, bearing serial number PJC084, seems to be in good general condition even if it is no longer able to function normally. It will be able to supply QAM aircraft with both alternating current and direct current once repaired and declared perfectly functional.
The QAM’s MMG-1A MEPP was donated by the École nationale d'aérotechnique in Saint-Hubert, QC. It is currently being restored to working order as part of student activities at the school with the financial support of Bell Textron Canada, Mirabel, QC.
