15 -- EP-3E FULL-SCALE FATIGUE TEST AND POST TEST ANALYSIS POC Sherita Crosby, Phone (301) 757-5216, AIR-2.3.2.2.1 or Maureen Bernard, Contracting Officer, (301)757-5248, AIR-2.3.2.2 E-MAIL: crosbys@navair.navy.mil, crosbys@navair.navy.mil. EP-3E FATIGUE TEST AND ANALYSIS SLAP PHASE I, PHASE II AND III The USN intends to modify the current P-3C Service Life Assessment Program (SLAP) contract N00019-99-C-1386 to add requirements necessary to address the EP-3E service life. The USN and Lockheed Martin Aeronautical Systems (LMAS) are currently conducting a program to assess the P-3C fatigue life and to identify critical locations requiring structural modifications to attain the 2015 service life goal. The EP-3E is a structural derivative of the P-3C. The USN and LMAS will utilize the existing P-3C full-scale fatigue test currently on contract to assess the service life of the EP-3E. The total fatigue life assessment program for EP-3 will be accomplished in three phases: I) Pre-Test Analysis; II) Full-Scale Fatigue Test; and III) Post-Test Analysis. A dedicated EP-3E donor aircraft will not be available for the EP-3E full-scale fatigue test. The effort will leverage the existing test effort conducted by LMAS under the current P-3C SLAPcontract N00019-99-C-1386. EP-3E peculiar structure will be tested using component tests where those structural elements represent primary or significant load bearing structure that is life limited. The USN intends to issue this modification sole source to LMAS, see numbered Note 22. Posted 04/14/99 (W-SN319935). (0104)
