Description of COSAL Parts and Sections
Since the COSAL and COSBAL are similar, we will
describe just the COSAL parts and sections. Certain
aviation components (aviation supply offices [ASOs])
will also be included in the COSAL when specifically
designated. For more information and complete
instructions in the use of the COSAL, we recommend
that you read the COSAL Use and Maintenance Manual,
SPCCINST 4441.170.
Each COSAL publication is produced in three parts.
Part I contains indexes. Part II contains associated APLs
and AELs. Part III contains allowances and cross-
reference data. The three parts are subdivided as follows:
Part I
Summary of Effective Allowance Parts/Equipage
Lists (SOEAPL)
Index–Section A (Equipment Nomenclature
Sequence)
Index-Sections B, C, D, and E
Part II
Section A–Allowance Parts Lists (APLs)
Section B–Circuit Symbol Data (microfiche only)
Section C–Allowance Equipage Lists (AEL)
Part III
