Purpose: This section identifies the parts of the assembly or assemblies in this manual that can be disassembled, repaired or replaced, and assembled. Any modification, addition, or deletion in the parts list table is shown by an "R" at the left of the item number. 2. Explanation and use of this section: A. Item numbers An item number identifies a part in all sections of the manual. The item number for a part usually does not change, but alpha variants of the item number can be added (refer to paragraph 2.B.). B. Alpha variant item numbers Note: An "Alpha Variant" is an alphabetic letter which follows the item number, and which "varies" (changes) each time that the item number is repeated in the parts list. The letters "A" through "Z" (but not I and O) follow copies of item numbers when it is necessary to show: (1) Added items (2) Items that are modified by a Service Bulletin (3) Different configurations (4) Alternate or optional parts (5) Improved parts that are not introduced by a Service Bulletin Alpha variant letters are shown in the figures only to identify parts that have a different appearance or location than the initial parts. C. Item not illustrated Parts that are not illustrated have a dash (-) before the item number. D. Service Bulletin Incorporation A service bulletin can cause assemblies, subassemblies, and detail parts to be added, removed, modified, or replaced. The NOMENCLATURE (part name) column shows "PRE SB XXX" (pre-Service Bulletin) when it is necessary to identify the initial configuration. "POST-SB XXX" (post-Service Bulletin) is shown to identify assemblies, subassemblies, or detail parts that are affected by the Service Bulletin. PRE SB XXX or POST SB XXX are not shown when: (1) The "EFF. CODE" column clearly shows the pre- or post-service Bulletin condition of the assemblies, subassemblies, or detail parts. (2) The end-item assembly is modified by a Service Bulletin and has no change to its part number (with no production equivalent of the modified assembly). PRE SB XXX" is not shown, and "POST SB XXX" is shown, when a subassembly or detail part is modified by a Service Bulletin and has no change to its part number. An alpha variant letter is also added to the item number. G. Effectivity code If more than one end-item assembly is shown in the parts list, a reference letter (A,B,C, etc.) is given in the EFF CODE column for each end-item assembly. This reference letter is also shown in the EFF CODE column for each detail part or subassembly that can be used only in the end-item assembly with the same reference letter. Detail parts and subassemblies can be used in all end-item assemblies if no reference letter is shown. H. Quantity for each assembly The UNITS FOR EACH ASSY column usually shows the full number of parts that are necessary for each assembly, subassembly, or sub-subassembly. The letters "AR" identify parts that are used "as required" (for bulk quantity parts such as lockwire). The letters "RF" identify parts that are given only for reference purposes. The letters "NP" identify parts that are "not procurable." Order the next higher assembly to get these parts. The letters "SP" identify parts that are "service parts." These parts are not supplied with the end-item assembly. Product data contained in this catalog has been derived from information obtained from Aviall's suppliers.
