FIELD MAINTENANCE
GENERAL INFORMATION
SCOPE
Type of Manual. This Technical Manual (TM) provides Operator's Instructions and Field Level Maintenance, and a
Repair Parts and Special Tools List (RPSTL) for the Improved Boat Cradle (IBC). Preventive Maintenance Checks
and Services, and maintenance procedures are included.
Equipment Name. Improved Boat Cradle (IBC).
Purpose of Equipment. The IBC will be used with the Common Bridge Transporter (CBT) or Palletized Load System
(PLS) trailer. The IBC shall not be transported on the PLS transporter due to lack of a lock-down device on the
transporter. The CBT system consists of a Transporter and a Load-Handling System (LHS). The CBT is a converted
Heavy Expanded Mobility Tactical Truck (HEMTT). The CBT provides the capability for transporting, launching, and
retrieving the Bridge Erection Boat, Twin Jet, Aluminum Hull (Model USCSBMK2, NSN 1940-01-218-2165) or M2R
(1940-01-547-4940).
MAINTENANCE FORMS, RECORDS, AND REPORTS
Department of the Army forms and procedures used for equipment maintenance will be those prescribed by (as
applicable) DA PAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual; DA PAM
738-751, Functional Users Manual for the Army Maintenance Management Systems - Aviation (TAMMS-A); or AR
700-138, Army Logistics Readiness and Sustainability.
REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR)
If your (insert equipment short item name) needs improvement, let us know. Send us an EIR. You, the
user, are the only one who can tell us what you do not like about your equipment. Let us know why you
do not like the design or performance. If you have Internet access, the easiest and fastest way to report
problems or suggestions is to follow the instructions and links below.
ALL non-Aviation/Missile Warranty EIRs and PQDRs must be submitted through the Web Product Quality
Deficiency Reporting (PQDR) site. The Web PQDR site is:
http://www.nslcptsmh.csd.disa.mil/webpqdr/webpqdr.htm. New accounts can be established at the
following address: http://www.nslcptsmh.csd.disa.mil/accessforms/uarform.htm.
You may also submit your information using an SF 368 (Product Quality Deficiency Report). You can
send your SF 368 using e-mail, regular mail, or fax using the addresses/fax numbers specified in DA PAM
750-8, The Army Maintenance Management System (TAMMS) Users Manual. We will send you a reply.
CORROSION PREVENTION AND CONTROL
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern, particularly since the IBC normally
operates in a wet environment. It is important that any corrosion problems with this item be reported so that the
problem can be corrected and improvements can be made to prevent the problem in future items.
Corrosion specifically occurs with metals. It is an electrochemical process that causes the degradation of metals. It
is commonly caused by exposure to moisture, acids, bases, or salts. An example is the rusting of iron. Corrosion
damage in metals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface residue, and/or
Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation (oxygen),
solvation (solvents), or photolytic (light, typically UV) processes. The most common exposures are excessive heat
or light. Damage from these processes will appear as cracking, softening, swelling, and/or breaking.
SF Form 368, Product Quality Deficiency Report should be submitted to the address specified in DA PAM 750-8,
The Army Maintenance Management System (TAMMS) Users Manual.
