CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army material is a continuing concern. It is important that any corro-sion 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 tomoisture, 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 cracking. Plastics, composites, and rubbers can also degrade. Degra-dation is caused by thermal (heat), oxidation (oxygen), salvation (solvents), or photolytic (light, typically UV) pro-cesses. The most common exposures are excessive heat or light. Damage from these processes will appear as cracking, softening, swelling, and/or breaking. The form should be submitted to the address specified in DAPAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual.

EQUIPMENT DESCRIPTION AND DATA
EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES
BasicEngine. The engine is designed to provide pneumatic power for aircraft Main EngineStart (MES) and air cycle refrigeration systems and shaft power for hydraulic and electrical system operation. The engine also shall provide air for general aircraft maintenance requirements.
The engine has three major sections; the compressor, turbine and accessory section.
Compressor Section. The single-stage compressor section is the source of compressed air for the turbine and bleed air for general aircraft use. Air enters the compressor inlet, is compressed in a centrifugal impeller and discharged through a two-stage diffuser into the turbine section.
Turbine Section. The turbine section consists of a turbine-wheel assembly, plenum, nozzle and single-can-type combustion chamber assembly. The turbine plenum serves as a receiver for compressor discharge air and as an enclosure for the combustion chamber and torus. The compressed air received by the turbine plenum is directed through the combustion chamber where fuel is introduced and burned; the hot gases then flow into the torus, which directs the flow into the turbine. The single-stage turbine consists of a radial, fixed-area nozzle and a radial, inward-flow turbine wheel that drives the compressor and gearbox. After passing through the turbine wheel, the gas discharges axially through a short diffusing section.
Accessory Secton. The accessory section provides two separate output pads to drive a hydraulic pump and a generator at 8000 rpm, the control systems and accessories required for engine operation. Control systems and accessories include; fuel system, lubrication system, low-energy type ignition system, electric starter, load control valve, LowOil Pressure (LOP) switch, high oil temperature switch, monopole speed sensor, EGT thermo-couple, hourmeter and the associated wiring harness. These items provide complete automatic engine control when used in conjunction with the 2117404-4 electronic control unit (provided separately from the engine).
Electronic Control Unit (ECU) and Fuel Control. Provide isochronous closed loop speed control by moni-toring speed and modulating fuel flow.
Automatic engine shutdown is provided by the ECU in the event of overspeed, exhaust gas overtemperature, ex-cess current draw in the control circuit, high oil temperature or low oil pressure. These driver circuits can actuate fault lights on a malfunction indicator panel to display the specific shutdown mode; fault circuits are latching with a "first fault wins" mode.

PRESHOP ANALYSIS
INITIAL SETUP:
Materials/Parts Solvent, Dry Cleaning, MIL-PRF-680 (WP 0062 00, Item 85)
SCOPE
The purpose of preshop analysis operations is to determine prior to beginning overhaul, at the highest assembly level possible, the work required to return the Pneumatic and Shaft Power Gas Turbine Engine Assembly (en-gine) to a serviceable condition as specified in the DMWR.
If inspection at the highest level of assembly is precluded by missing, damaged or diagnosed defective assem-blies, consideration will be given to techniques that would allow continued inspection at that level. If this is not possible, inspection will proceed at the next lower level.
The preshop analysis checklist will be used to record the results of the analysis and any required maintenance.
When a 100 percent teardown overhaul will be accomplished, a preshop analysis is not mandatory.
INSPECTION OF FORMS
Check all tags and forms attached to the engine to determine the reason for removal from service and other dis-crepancies. Do not remove tags from the engine. If tags aremissing, information they contained will be furnished by the previous owning activity.
