MAINTENANCE MANUAL
(c) Apply “Texize K-2R Spot Remover” by spraying or rubbing into the fabric and let dry.
Vacuum off the residual powder. Repeat if necessary or wet a cloth with a solvent type
spot cleaner such as “Energine” or “Renuzit” and wipe or gently rub the stained area. Turn
cloth and rewet with solvent often. Repeat until stain disappears.
(d) To remove residual detergent left on the fabric, wipe the entire fabric surface with a cloth
dampened with water. The cloth should be rinsed in clean water several times. This
procedure will ensure that the treatment will continue to function.
H. Carpets
WARNING: SOLVENT CLEANERS REQUIRE ADEQUATE VENTILATION.
Use a small whisk broom or vacuum cleaner to remove dirt. For soiled spots, use a nonflammable
dry cleaning fluid. Floor carpets may be removed and cleaned like any household carpet.
I. Cleaning and Maintenance of Relief Tube System
CAUTION: THE CORROSIVE AFFECTS OF URINE ON PAINTED AND UNPAINTED SURFACES
CANNOT BE UNDERSTATED. CORROSION MAY APPEAR IN SURROUNDING
AREAS IF CLEANING IS DEFERRED FOR EVEN ONE DAY!
For airplanes equipped with a relief tube system, the corrosive effects of urine or other liquids
poured through the system are extreme and heightened attention to the cleanliness of this system
is indicated, both inside and outside the aircraft. In the interior, the funnel tube assembly, rubber
hose and surrounding sheet metal must be cleaned at the termination of each flight, if the system
has been used. Likewise, attention to the exterior of the aircraft is equally important and exterior
surfaces must be cleaned as described below.
(1) Interior
CAUTION: SHOULD SPILLAGE EXTENDING INTO THE FUSELAGE BE EVIDENT,
PROMPT MAINTENANCE ACTION IS REQUIRED TO ENSURE URINE
SPILLAGE IN THE FUSELAGE STRUCTURE IS NEUTRALIZED. REMOVE
PANELS TO ACCESS THE FLOOR STRUCTURE AS REQUIRED.
(a) After each use of the relief tube, the area surrounding the relief tube should be examined
for spillage and cleaned according to the procedures in paragraphs E (4) and E (5),
above. Clean the area inside the box and access door, funnel, and tube using mild soap
and water. After cleaning, flush with clean water to ensure that no soapy residue remains.
Dry system thoroughly.
(b) Prepare to flush the relief tube assembly by placing a catch can underneath the relief tube
outlet. Flush tube by pouring a solution of baking soda (10%) and water through the tube,
flushing out the entire system. Flush again with at least 1/2 gallon of clean water. Low
pressure (LP) shop air may be blown through the relief tube system to dry it.
(2) Exterior
Exterior bottom painted surfaces of the airplane must be cleaned from the firewall to the tip of
the tail, including the bottom of the tail surfaces, at termination of each flight during which the
relief tube system was used. Cleaning should occur per paragraph C, above, with the
exception that after completion of washing, a solution of baking soda (10%) and water should
be applied to the entire area and allowed to remain for a few minutes. The area must then be
thoroughly rinsed with clean water. Dry the area thoroughly and inspect for paint chipping
and/or corrosion. Touch up paint as necessary.
