A. Preparation of the Blue Dye Oil System Leak Check Solution (PS 197)
(1) Make-up of the PS 197 blue dye solution

Materials	Make-Up	Operating Limits
PMC 4513 blue dye (Material No.P05-459)	8 - 9 milliliters	150 plus or minus 40 ppm
P03-001lubricant, aircraft turbine engine	10 gallons (37.85 liters)

NOTE: When the engine is first refilled with non-dyed oil, the non-dyed oil will mix with the remaining (that is, residual) dyed oil. The color of this mixture will likely be darker than the non-dyed oil that was just added. The color of various oil brands can be different. This color change is permitted and is not a negative indication of the condition of the lubrication system.

(2) Preparation of the PS 197 blue dye solution
(a) Add the specified amount of P03-001lubricant, aircraft turbine engine to the mixing container.

NOTE: The selection of base oil (Approved PWA 521, Type II) will make it easier for the operator to see the blue color of the dyed oil. Pratt & Whitney experience finds that light color PWA 521, Type II base oils are more easily detected with the PMC 4513 blue dye (Material No.P05-459) .

(b) Add the specified amount of PMC 4513 blue dye (Material No.P05-459) .

NOTE: It is necessary to put PMC 4513 blue dye (Material No.P05-459) through a five-micron or less membrane filter six weeks or less before you mix it with P03-001lubricant, aircraft turbine engine for PS 197.

NOTE: This solution is organic.

(a) Do not permit the solution to touch the skin, eyes, nose or throat.
(b) Do not take this solution internally.
(c) Be sure to wash fully after handling and before you drink or smoke.
(d) Keep this solution away from food.
(e) Do not breathe the dust, vapors, mists or gases.
(f) Use this solution with sufficient ventilation.
(g) Keep this solution away from heat or flames because toxic mixtures can occur.
(h) Be sure to wear the necessary safety equipment.
(i) Keep this solution away from oxidizers.
