National Guard Repair Depot Key to Army Aircraft Maintenance

At the Connecticut National Guard's 1109th Aviation Classification and Repair Depot, workers refurbish and maintain the Army's fleet of rotary-wing aircraft. This unique job can save the War Department millions of dollars a year.

Unlike field units that are trained and equipped to conduct basic maintenance on their aircraft, the repair depot is capable of stripping a helicopter — whether it's a UH-60 Black Hawk, a CH-47 Chinook or an AH-64 Apache — to its nuts and bolts and rebuilding it to factory standards, as if it just rolled off the assembly line.

"We are considered a sustainment-level facility in that we can do the highest-level maintenance comparable with any Army aviation depot," said Army 1st Sgt. Jarod Meekhoff, a quality control inspector for aircraft and aviation maintenance at the repair depot. "The kind of work that we do is highly technical, which is why we have a lot of specialized tools, equipment and specialized individuals here with the knowledge and skills capable of doing that."

Connecticut is home to some of the country's largest military-industrial businesses. It is fitting, then, that Connecticut is also home to the repair depot. The facility, based in Groton, Connecticut, employs highly skilled uniformed mechanics and some of the industry's most experienced civilian contractors to refurbish and maintain the aircraft.

"In doing depot maintenance, we can basically take an aircraft and overhaul it from the ground up," Meekhoff said. "That's removing all the components, stripping all the paint, doing significant structural upgrades, structural repairs, component repairs [and] component overhauls." 
 
One of the best examples of this facility's cost-saving capability came in 2019, when the repair depot received two battle-damaged Chinooks that were deemed inoperable. In just two years, even with the constraints imposed by the COVID-19 pandemic, these two helicopters were stripped down, analyzed, repaired, repainted and returned to the fleet as fully functional machines, sparing the military millions of dollars in buying new helicopters. 
 
Holding important certifications qualifies the repair depot to bid on special aviation maintenance projects offered by the Army. This allows soldiers and contractors at the facility to develop skills and knowledge comparable to those of their civilian defense industry counterparts.

Working at the depot provides an opportunity for those interested in the aviation or aerospace industries to acquire skills and experience that will help advance their careers. 
 
"Because of the level of maintenance and the kind of very technical maintenance that we do, our maintainers will walk away with a much better understanding of not just helicopters and aircraft, but general maintenance and procedures, which absolutely translates to all the civilian companies that do any sort of production, manufacturing or assembly," Meekhoff said. 
 
In addition to the repair depot, the facility is home to the 1109th Theater Aviation Support Maintenance Group, the traditional National Guard unit to which many of the uniformed personnel are assigned. These soldiers are capable of going downrange and performing high-level depot maintenance on aircraft on the front lines of the War Department's efforts to maintain peace and stability worldwide.
