R A. Aircraft Maintenance Configuration
R (1) Drain the water from all of the fuel tanks (Ref. TASK 12-32-28-281-
R 001).
R (2) Defuel the aircraft (Ref. TASK 28-25-00-650-001).
R (3) Drain the remaining fuel from all of the tanks (Ref. TASK 28-25-00-

R B. Removal of the Microbiological Particles
R (1) Do the procedure for the removal of microbiological particles
R (Ref. TASK 28-11-00-600-003).
R NOTE : Do this procedure as soon as possible. This will prevent____
R corrosion of the fuel tank structure.
R Subtask 28-11-00-670-060
R C. Biocidal Shock Treatment for Heavy Contamination - with Fuel Mixed with
R Biobor Biocide
R (1) In not more than 10 days, refuel all the fuel tanks to the maximum
R capacity with fuel mixed with MICROBIOLOGICAL CONTAMIN. PROTECT.
R MATERIALS (Material No. 17-003), at a concentration of 270 ppm
R (Ref. TASK 12-11-28-650-003).
R NOTE : AIRBUS recommends that you refuel the aircraft to the maximum____
R capacity. If this is not done (for operational reasons),
R microbiological contamination can stay in the upper part of
R the tanks.
R (2) Let the fuel stay in the tanks for between 36 and 72 hours.
