Definition Definition of approved item name (AIN): "GENERATOR,ENGINE ACCESSORY"

A generator primarily designed to be mounted on an internal combustion engine, and to be driven by the engine to keep the battery in a charged condition. May also supply current for the engine ignition system and/or electrical equipment which is connected to the battery circuit. Includes alternating current generators designed for use with a rectifier. Excludes the major generator of "generating sets". For generators specifically designed for aircraft use and not mounted on the engine, see generator, direct current.

  Identification Codes

HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.

PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.

ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.

ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.

CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
