Restoration Chronology

	May 31st, 2022 After being used by the École nationale d'aérotechnique to power a Bombardier CL-601 Challenger and a Dornier 328, the "Mobile Electrical Power Plant" MMG-1A was stored outside for many years following an unresolved malfunction. It was scheduled to go to the scrapyard. TOP OF PAGE
	June 22nd, 2022 The MMG-1A is donated by the ÉNA to the QAM, which then prepared a STEM project with this GPU for the benefit of the "Avionics" student club of the School. The equipment is sheltered in the A22A hangar alongside the AFSG-1 GPU, also the subject of a STEM project. TOP OF PAGE
	September 14th, 2022 An initial exterior cleaning was carried out and, two days later, Bell Textron Canada became the project sponsor, thus making it possible to acquire the equipment required to put the MMG-1A back into operation. TOP OF PAGE
	September 2022 till November 2023 Not having any electrical diagram other than the wiring diagram present on the MMG-1A, a “reverse engineering” process is initiated. The manufacturer NAVAIR was contacted, but without success. As for the Naval Air Museum in Pensacola, Florida, no documentation is available on this side as well. However, museum officials wish to follow the evolution of the MAQ project. TOP OF PAGE
	November 1st, 2023 The internal cleaning of the MMG-1A began. Over the years, dust and grime inevitably built up inside the device. But this does not demotivate our students, quite the contrary! TOP OF PAGE
	November 1st, 2023 Two representatives from Bell Textron Canada's Product Support Engineering came to visit the students from the "Avionics" group carrying out the refurbishment of the MMG-1A. TOP OF PAGE
	February 7th, 2024 Students from the “Avionics” group were preparing to assemble a relay test box of their design. TOP OF PAGE
	February 7th, 2024 After dismantling the structural elements providing access to the AC-DC conversion circuits, we saw that they would require a little cleaning! TOP OF PAGE
	March 20th, 2024 Assembly of the AC relay test box continued. TOP OF PAGE PAGE
	March 20th, 2024 Simultaneously, two students began a first thankless job of cleaning the DC section of MMG-1A. TOP OF PAGE
	September 25th, 2024 A new 440 VAC 100 amp three phase connector was installed on the power cable. TOP OF PAGE
	October 1st, 2024 The reverse engineering process began on the DC section of the MMG-1A. Diagrams were drawn based on what was discovered, sometimes by dismantling certain components. TOP OF PAGE
	October 1st, 2024 At the same time, a few students took care of repairing the mechanical brake system. TOP OF PAGE
	October 4th, 2024 Diagrams are made in draft following observation of the circuits and thanks to the wiring diagram present on the MEPP. They will gradually be transcribed into a CAD format. TOP OF PAGE
	October 23rd, 2024 Cleaning of the DC section of the power supply unit continued to facilitate the reverse engineering process to determine its operation. TOP OF PAGE
	October 23rd, 2024 It is a damaged cable which turned out to be the cause of the malfunction of the brake mechanism. It was therefore dismantled in order to evaluate repair or replacement options. TOP OF PAGE
	November 6th, 2024 The reverse engineering process continued in the DC section of the MEPP for which we do not have any diagram. It consisted of identifying all the components and identifying each wire connecting them to each other in order to establish the diagram of the entire circuit. TOP OF PAGE
	November 13th, 2024 A student analyzed an electronic printed circuit during the “reverse engineering” process. Fortunately, the two printed circuits forming part of the DC section are of fairly simple design. TOP OF PAGE
	November 13th, 2024 Following the path of each wire required patience! TOP OF PAGE
