In early May, at an undisclosed location in Southwest Asia, Tech. Sgt. Chance Cole, 386th Expeditionary Aircraft Maintenance Squadron flight line expediter, came up with an idea – and it’s going to save the Air Force a lot of money. Each time maintenance personnel were unable to replace a spline insert, they actually had to remove and replace a much larger and more complex assembly, the Permanent Magnetic Alternator (PMA). This process had been accomplished multiple times in the past due to an inability to remove a damaged insert and it added unnecessary time and expense.
