    1. FUEL TANK TOPCOAT PEELING (FTTP) UPDATE Presented by Peter Augostini Kisor Engineering Air Force Corrosion Program Conference March 11, 2003

    2. FTTP UPDATE Points of Contact F.D. Kisor, Kisor Engineering 817-249-1602, fkisor@flash.net Peter Augostini, Kisor Engineering 817-274-4129, paugostini@aol.com CMSgt David Pentecost, AFCPCO DSN 468-3284, david.pentecost@robins.af.mil

    3. Contract Objective Information Collection from all program sources. Under contract with Aging Aircraft Office FTTP UPDATE

    4. Introduction Background History FTTP Conference-Tinker AFB August 13-14, 2002 Represented: OC-ALC/LHR (B-52); PPG; OC-ALC/LCR (KC-135); DESC; JAX-NADEP; ARINC, Okla. City; AFRL/PRTG; WR-ALC/AFTH; AFRL/MLSA; Boeing-Wichita; Phoenix Mgt., Inc. FTTP UPDATE

    5. General Summary of Findings Information is ‘preliminary and incomplete’ B-52 Program KC-135 Program P-3 Program Others FTTP UPDATE

    6. FTTP UPDATE

    7. FTTP UPDATE

    8. FTTP UPDATE

    9. B-52 Program Only B-52Hs presently in use BMS 10-39, Mil-C-27725, BUNA-N >53 aircraft affected Expect ‘all’, eventually Inboard and lower surfaces severest Corrosion secondary to topcoat peeling FTTP UPDATE

    10. KC-135 Program Current models from early 60s BMS 10-39, Mil-C-27725, BUNA-N Topcoat peeling on numerous aircraft Inboard worse than outboard Recoating not done after removal Corrosion not an issue FTTP UPDATE

    11. P-3 Program Manufactured from ‘60s thru ‘80s Buna N, Mil-C-27725 Topcoat peeling on numerous aircraft Corrosion is equally severe Peeling more severe in foam-filled tanks Severest peeling-corrosion in headspace FTTP UPDATE

    12. Other Aircraft Minor chipping/peeling Aircraft investigated A-10 E-3 767 B-1 F-16 DC-10 C-130 KC-10 S-3 DC-9 C-141 FTTP UPDATE

    13. Common Denominators Older Aircraft Primarily BMS 10-39 Fuel System Icing Inhibitor Change: (EGME to DIEGME) JP-4 to JP-8 N.B.: Preliminary FTTP UPDATE
