SECTION IV. MAINTENANCE PROCEDURES
2-9. General Maintenance Procedures.
a. Maintenance of the fuel boost pump is provided individually for the pump housing assembly and for the pump
cartridge assembly. In most cases only the pump cartridge will be forwarded to AVIM for maintenance procedures.
The housing will remain installed on the aircraft. In the case where the pump cartridge and housing assembly are for-
warded as a complete assembly, the cartridge and housing must be separated before maintenance procedures are per-
formed on either one.
b. When a maintenance procedure is required, instructions will usually be limited to removal of the part being
repaired or replaced. The equipment must meet the condition requirements before the task is started. This will usually
mean disassembling the component as described in the referenced task to uncover the items referenced by your main-
tenance task.
c. Before beginning the task, read and become familiar with the task. Bring all the tools, materials, and parts listed
to the work site before you begin the task.
