 ú  (2) Use one of the approved test kits to test the fuel samples.
 ú  (a) Follow all instructions supplied with the test kit.
 ú 
        ú
 NOTE: Some test kits will not function correctly if fuel is____
 ú  tested. Even traces of fuel can coat the test slide and
 ú  prevent the microbes from growing. Other test kits can
 ú  test either fuel or free water, but free water is
 ú  recommended.

 ú  S 287-106
 ú  (3) Use the data supplied with the test kit and analyze the level of
 ú  contamination.
 ú
 ú  S 977-107
 ú  (4) Record the test results.
 ú  I.  Test Results
 ú
 ú  S 757-108
 ú  (1) If the test results show the presence of microbial contamination,
 ú  get a new fuel/water sample within 10-14 days of test results and
 ú  repeat the microbial detection test with the same test method.
 ú
 ú  S 757-109
 ú  (2) If the retest also shows heavy microbial contamination (as defined
 ú  by the test kit), within 10-14 days after the test results, do these
 ú  steps:
 ú  (a) Remove the microbial growth (AMM 28-11-00/701).
 ú  (b) Examine the fuel tank structure for corrosion (SRM Chapter 51).
 ú  (c) Do a biocide treatment of the fuel tanks (AMM 28-11-00/201).
 ú  (d) Within 10 days, get a new fuel/water sample and do the
 ú  microbial detection test again.
 ú 
        ú
 NOTE: This test is necessary to make sure the microbial growth____
 ú  removal and biocide treatment processes have reduced the
 ú  level of microbial contamination to an acceptable level.
 ú
 ú  1) Make sure all of the biocide treated fuel has been burned
