Dover Duties: 436th CES water and fuels systems maintenance
Members of the 436th Civil Engineering Squadron water and fuel systems maintenance, U.S. Air Force Airman 1st Class Hayden Salyer, 436th Medical Group bioenvironmental engineering journeyman, and Chief Master Sgt. Christopher Smith, 436th Operations Support Squadron senior enlisted leader, place a unique plate into a fuel filter separator during a Dover Duties tour at Dover Air Force Base, Delaware, Feb. 26, 2026. Due to high particulate levels in the filters, the Dover Duties participants replaced the old filters with new ones, ensuring the fuel pressure remained balanced.
