Jet Parts Engineering has won FAA approval for nine new parts manufacturer approval (PMA) parts and three new designated engineering representative (DER) repairs, adding to the Seattle-based company's expanding catalog of aftermarket components for commercial aircraft. The newly certified items include stud nuts, rods, packings and other hardware built to support major platforms such as the Boeing 737, the Embraer E170 and the CFM International CFM56 engine family, according to Aviation Week's rolling MRO industry update for August.
The approvals give airlines and independent maintenance shops another certificated, cost-effective sourcing option for parts that support some of the most widely operated aircraft and engines in the US commercial fleet. PMA parts allow operators to install FAA-approved alternatives to original equipment manufacturer components, a practice that has become increasingly important as supply chain constraints continue to squeeze lead times across the maintenance, repair and overhaul industry.
DER repair authority lets Jet Parts Engineering develop and approve its own repair procedures for parts that would otherwise need OEM sign-off, shortening turnaround for operators facing tight maintenance schedules. The company's steady cadence of monthly PMA and DER announcements throughout 2026 reflects broader industry pressure: aging fleets, extended aircraft utilization and continued new-aircraft delivery delays have pushed airlines to rely more heavily on the aftermarket parts and repair network to keep aircraft airworthy and flying.
Industry analysts have described the current environment as an MRO "super cycle," a stretch of elevated demand across nearly every segment of aircraft maintenance. New parts and repair approvals from suppliers such as Jet Parts Engineering are one of the ways the supply side is working to keep pace.
