The Federal Aviation Administration proposed a $2,839,900 civil penalty against PEMCO World Air Services of Tampa, Florida, alleging the aircraft repair station knowingly used expired materials while performing maintenance on five Frontier Airlines aircraft.
The FAA alleges that PEMCO used expired adhesives, epoxies, resins, paints, and fiberglass cloth during maintenance performed on the aircraft between September 2022 and November 2023. By using the expired materials, the agency alleges PEMCO failed to follow both the aircraft's maintenance manual and the company's own quality control manual.
The proposed penalty, announced in February 2026, is among the larger civil enforcement actions against a US-based Part 145 repair station in recent years. PEMCO World Air Services operates as a certificated repair station providing aircraft maintenance, conversion, and modification services.
The case highlights ongoing FAA scrutiny of repair station quality management practices. The FAA's Office of Inspector General also announced a targeted audit in 2026 examining consistency in how FAA field offices certify domestic repair stations, the third in a series required under the FAA Reauthorization Act of 2024.
The enforcement action against PEMCO comes as the FAA has published updated regulations requiring Part 145 repair stations to maintain documented digital recordkeeping systems, including audit trail capability and user access controls, as part of mandatory electronic records requirements that took full effect in 2026.
PEMCO has the right to respond to the proposed penalty and request a hearing before an administrative law judge.
