SECTION I. CMB GENERAL INFORMATION1. PURPOSE. This document contains information about Contact Memory Buttons (CMB) and procedures for in-stalling and removing CMBs. It also defines which AH-64A/D helicopter components receive CMBs.
NOTE
The aircraft components requiring maintenance management and historical data reports in this doc-ument are taken from TB 1-1500-341-01.
All components requiring CMBs are in Table 1 of this document.
2. CMB GENERAL INFORMATION.
a. Description: This section provides general background information about Contact Memory Buttons (CMB).
b. General Information: A Contact Memory Button (CMB) is a battery-free, read/write electronic data storagedevice attached to selected components tracked by the DA Form 2410. The CMB enhances configuration manage-ment, asset tracking, inspection and maintenance for the life of the component to which it is attached.
Aviation Maintenance Automated Tracking System (AMATS) is an automated system that uses CMBs to inputpart data into an existing maintenance management information system (MMIS). Data stored on the CMB is retrievedusing a CMB read/write device attached to a computer or personal digital assistant (PDA). Information is viewableand updateable on site. The retrieved information is then automatically inputted into the MMIS. Together, CMBs andan MMIS create an automated maintenance environment. After maintenance is performed on an aircraft componentand the maintenance data is entered into the MMIS, the computer or PDA is used to write the current data to thecomponents CMB.
The CMB currently in use by AMATS is part number BMEWK32, CAGE code 03BF3. This CMB, the MacSemaMiniButton is 0.11 in. high, 0.56 in. in diameter, and weighs 0.027 oz.

SECTION II. REMOVING A CMB
3. REMOVING A CMB. This section covers removing a CMB from a component.
a. Description:
b. Initial Setup
Materials: Tools:
Dry Ice (Item 1, Table 2) Phenolic Wedge
Corrosion Preventive Compound (CPC) (Item 9, Table2)
Dry ice is solid carbon dioxide that has a temperature below -112 F (-80 C). Contact with skinwill cause serious low temperature burns. Temperature resistant gloves/apron required. Carbondioxide displaces oxygen, which can cause asphyxiation. Use only in a well ventilated area.
When removing a CMB, care should be taken not to damage the surface of the component.
c. Removing a CMB
Use dry ice to crystallize the Hysol EA 9394 that holds the CMB to the component. This can be accomplisheby applying dry ice to the CMB area for 4-5 minutes. The adhesive should become brittle.
Place an authorized blunt object, preferably a phenolic wedge, at the lip of the CMB.
Gently tap the blunt object to loosen the CMB, and eventually tap it free from the adhesive.
Any metallic surface that is exposed due to the CMB removal should be treated with the appropriate corrosionpreventative compound.
SECTION III. INSTALLING A CMB
4. INSTALLING A CMB.
a. Description: This section covers installing a CMB onto a component.

TB 1-1520-238-20-140
Use all chemicals in a well-ventilated area. Refer to the Material Safety Data Sheet (MSDS) docu-ments for the chemicals for specific safe handling procedures.
Heat buildup during or after mixing Hysol EA 9394 is normal. However, do not mix quantitiesgreater than 450 grams, as dangerous heat buildup can take place, causing uncontrolled decom-
position of the mixed adhesive. As a result, toxic fumes are formed.
Use latex gloves when handling Hysol EA 9394.
Always use latex gloves during installation of CMBs to prevent contamination from oils and dirt onhands.
Hysol EA 9394 must be mixed well in order for the adhesive to bond correctly. Mix the adhesivefor several minutes until the color and consistency are uniform.
The ambient conditions during installation can affect the cure times for the adhesive. Do not install
CMBs at ambient temperatures below 50F, or the adhesive will not properly cure.
Do not apply paint, corrosion preventive compound, or adhesive over the top of the CMB. Doingso can prevent proper CMB read/write operation. If any of these substances get on the CMB, useacetone to clean the CMB, and then try reading the CMB. If the CMB cannot be read in its entirety,remove and install a new CMB in its place.
Care should be taken not to damage the metal surface of the component when preparing a com-ponent for CMB installation.
NOTE
Gather all necessary tools and materials before starting the CMB installation (See Table 2).
Refer to Figures 2 through 214 for proper placement of CMBs on components.
b. General Information: A CMB is permanently affixed to a component by Hysol EA 9394 adhesive.
c. Initial Setup
Materials:
Acetone (Item 5, Table 2) Lint-Free Cloth (Item 8, Table 2)
Latex Gloves (Item 6, Table 2) Emery Paper, 220 Grit (Item 4, Table 2)
Contact Memory Button (Item 7, Table 2) Adhesive, Hysol EA 9394 (Item 2, Table 2)
Scotch-Brite (Item 3, Table 2)
d. Installing a CMB on a component with any coated surface (paint, primer, clear coating, Pro-seal, etc.). Ref-erence paragraph 3.5 for installation of CMBs to bare metal surfaces.

Care should be taken not to expose any bare metal.
Scuffing of the main rotor and tail rotor blades should only be done in a spanwise direction.
NOTE
Use of power tools is not permitted unless approved by RDECOM Aviation Engineering Directorate(AED).
The adhesive must form a complete bead around the outside circumference of the CMB.
(1) Clean the selected location using acetone and a lint-free cloth. Remove all oils and solids from the area
(2) Lightly scuff a inch diameter area using a Scotch-Brite pad or 220 grit emery paper. Care should betaken not to expose any bare metal. If any bare metal is exposed during scuffing, prime and paint the area. Aftethe appropriate drying time, re-scuff the area.
(3) Clean the scuffed area with acetone. Dry wipe the area with a lint-free cloth before the solvent evaporates to remove any drying residue.
(4) Allow the area to dry completely (about 5 minutes), and inspect for proper surface preparation.
(5) Lightly sand the back side of the CMB for a few seconds with 220 grit emery paper and wipe clean witha lint-free cloth to prepare the back surface for bonding.
(6) Mix the Hysol EA 9394 adhesive according to manufacturers directions.
(7) Place a small amount of Hysol EA 9394 on the back surface of the CMB.
(8) Firmly press the CMB onto the component surface, ensuring a small bead forms entirely around theCMB. Take care not to get adhesive on top of the CMB.
Make sure the CMB is safe from loading or jarring until proper handling strength of the adhesivehas been reached. Handling strength for Hysol EA 9394 will occur after 8 hours at 77 F. Only ifthe cure inspection test is passed (see 3.4.11 below), it is safe to fly the aircraft 24 hours after CMBinstallation without risk of stressing the bonded joint to the point of breaking during flight. Full curetime (7 days at 77 F or 25 C) is determined to be the time after which the adhesive has developedmaximum bond strength, maximum environmental resistance, and ultimate performance properties.
(9) Hold the CMB with your thumb until it remains where placed.
(10) Remove excess adhesive from the work area before it hardens. Use acetone for removing any unnecessary, uncured adhesive. Do not disturb the adhesive bead.
(11) To ensure proper curing of the adhesive, wait 24 hours, and test for hardness. Randomly inspect 5CMBs or 10% of CMBs, whichever is greater. Inspect this quantity/percentage for each mixed batch of adhesiveused. The test involves using yourfingernail or other object of similar hardness and applying pressure to the beadof the adhesive.
(a) If this test leaves a visible mark on the adhesive, then the adhesive is not adequately cured, andoperation of the component would introduce a possible FOD (foreign object damage) risk. The adhesive might bebad, or it could just be a little cool and thus needs more time to cure. Either remove and reinstall the CMBs (restartinat step 3.4.1) or wait and re-inspect later. If the adhesive never passes this test, then the CMBs must be removed

and reinstalled (restarting at step 3.4.1). Either remove all CMBs installed using this mixed batch of adhesive, orremove only those for which the cure test fails (after testing 100% of the CMBs installed with this mixed batch).
(b) If no mark is left, then the adhesive has passed the cure inspection test.
(12) If touch-up paint is needed:
(a) The disturbed area must be returned to the condition stated for the component on the drawing.
(b) Mask the CMB.
(c) Apply touch-up paint around the CMB as needed.
(d) When the paint has dried, remove the masking from the CMB.
Do not scuff bare metal parts.
e. Installing a CMB on a bare metal surfaced component.
(1) Clean the selected location using acetone and a lint-free cloth. Remove all oils and solids from the area.Do not scuff bare metal parts.
(2) Follow procedures d.5 to d.11.b.
SECTION IV. CMB LOCATIONS
5. CMB LOCATIONS
a. Description: This section identifies the individual components to which CMBs are to be permanently attachedand the location of the CMB on each such component.
b. General Information: The U.S. Army has designated the individual components to which CMBs are to bepermanently attached. All such components are DA Form 2410 items, although not all DA Form 2410 items receivepermanently attached CMBs. Use the figures in this section to locate the position of the CMB on each component.

Whenever possible, place the CMB at its designated location. Failure to do so could result in inter-ference with the full motion of the component once installed on the helicopter.
If for some reason a CMB can not be installed at the designated location, place the CMB in theadequately sized location nearest the designated location that will not interfere with moving parts
and that is accessible to read/write once installed on the helicopter.
NOTE
All components and their variations in the following figures and in Table 1 receive a CMB as long asthe component is still on the Armys active parts list. A figure within this section may only show oneof several variations of the same component due to their different part numbers.
