B.The Standard Practices Manual consists of all of the process standard practices used for the maintenance operations on CF6 Commercial Turbofan, GE90 Turbofan, GE9X Turbofan, GEnx Turbofan, CF34 Turbofan, Passport 20 Turbofan, Catalyst Turboprop, CT7 Turboprop, and CT7 Turboshaft Engines; as well as LM500, LM1600, LM2500, LM5000, and LM6000 aero-derivative engines. It is used in conjunction with the Engine/Shop Manual and Service Bulletins to eliminate repetition of these processes throughout these documents.
C.The Standard Practices Manual provides one consolidated source of the detailed information required by the airline maintenance personnel. The Chapter No. of the required process of the Standard Practices Manual will be listed in the appropriate sections of the Engine/Shop Manuals.
2 . Definitions and Format of Standard Practices Manual.
Subtask 70-00-00-100-051
A.A standard practice is a single process that is required for the maintenance of numerous parts that are included in the engine. Each process has a defined area of application for accomplishing a specific task. It is identified by a 6-digit ATA number, for example, 70-21-06. Each process also has a 12-digit TASK number, for example, TASK 70-21-06-110-004, Cleaning Method 6 - Heavy-Duty Alkaline Cleaner (Without Inhibited Phosphoric Acid). The first six digits of the TASK number are always the same as the 6-digit ATA number for that process. A TASK number is always followed by the title of the TASK.
B.A category of processes that can be performed in the same shop area are assigned with ATA numbers whose first 4 digits are identical. Each category is divided per the following:
(1)70-XX-00: General
(2)70-XX-01 through 70-XX-79: Process Standard Practices
(3)70-XX-80 through 70-XX-98: Test Practices and Process Control
(4)70-XX-99: Special Instructions
C.The General data for each category defines the particular characteristics of the category processes and nonspecific data to guide the maintenance personnel in utilizing the processes.
D.The Test Practices and Process Control data provides the definition of the evaluation or verification of the quality of the process employed on samples of an identical or equivalent nature to the engine hardware. It also specifies the limits required for acceptability criteria.
E.The Process Standard Practices data defines the general information relating to the process and the detailed instructions regarding the equipment, method, and quality assurance.
F.The Solution Sheets define the technical information required for the baths relative to their composition, checking, regeneration, replacement, and temperature. These sheets are included in section 70-00-99 of this manual.
G.The Standard Practices Manual references a number of consumable products and compounds which are defined in the Consumable Products List in data 70-80-XX.
GEAE material specification numbers are included with materials in the Standard Practices Manual when no International, Aerospace, or US standard is currently available to reference. The material specifications indicate that the commercial quality of the material supplied by the supplier has been evaluated to the GE specification and found acceptable. The supplier can provide a certificate of authenticity with the purchase of the material that states the material meets the given specification. Refer to Step 3.C. in , Consumable Materials Section, for details.
H.Throughout the Standard Practices Manual, the terms "percent" and "percentage" and the symbol "%" shall mean percent by weight. Percent and percentage by volume shall be designated by the term "volume percent" or the symbol "V/V".
3 . Safety.
