E-MAIL—Electronic Mail (Internet). ECAMS—Enhanced Comprehensive Asset Manage- ment System-An automated system developed to process selected nontactical flight data in support of the RCM concept. Nontactical data is recorded on a data storage unit on board the aircraft to capture engine exceedances, engine performance data, and life limited component usage data. ECOMTRAK (SYSTEM)—Engine Composition Tracking (System)—An automated system used for tracking the composition, location, and operating time/cycle counts or life usage indexes of aircraft engines, propulsion systems, modules, and life limited components. ECOMTRAK is used to develop long range schedules for inspections, removals, replacements, procurements, and rework schedules for these components, based on usage requirements and fixed or variable usage rates. It provides important support to the RCM Program. ECP—Engineering Change Proposal—A term that includes both a proposed engineering change and the documentation by which the change is described and suggested. EDDY CURRENT—A method that uses induced eddy currents in detecting flaws in metal parts, such as cracks, inclusions, voids, seams, and laps. This method can also be used for sorting according to alloy temper, conductivity, and other metallurgical factors by variations in electrical characteristics/energy losses. EGRESS SYSTEM—An egress system is an ejection seat, interconnect and sequence system, installed parachute and seat survival kit, and the explosive devices and rocket motors used in their propulsion. It also includes hatches or canopies which are shattered or jettisoned from the aircraft by use of explosive devices. EHR—Equipment History Record. EIS—Equipment in Service. ELAPSED M/T—Elapsed Maintenance Time—The number of clock hours involved in making a repair. EM—NALCOMIS OMA End User’s Manual. EMT—Elapsed Maintenance Time—For the purposes of Maintenance Data Reporting, EMT is defined as the actual clock time, in hours and tenths, that maintenance was being performed on a job. EMT does not include the clock hours and tenths for cure time, charging time, or leak test when they are being conducted without maintenance personnel actually monitoring the work. Although the EMT is directly related to job man-hours, it is not to be confused with total man-hours required to complete a job. For example, if five men complete a job in 2.0 hours of continuous work, the EMT=2.0 hours and the man-hours=10.0. ENCL—Enclosure (correspondence). END ITEM—A final combination of end articles, component parts and materials that is ready for its intended use; for example, aircraft, NC-2A, or avionics test bench. ENGINE ACCESSORIES—Those items of equip- ment required for engine operation that are not an integral part of the engine. Such equipment is included in the engine IPB. In most cases, they are attached to the engine but, in special situations, could be airframe mounted, such as oil pumps, fuel controls, engine-driven fuel pumps, temperature amplifiers, afterburner controls, carburetors, magnetos, distributors, and ignition harnesses. ENROUTE —The physical movement of aircraft incident to change in its physical or reporting custody. EOC CODE—Equipment Operational Capability Code—EOC Codes relate a particular system/ subsystem within a T/M/S of equipment to a specific mission. An EOC Code is a three-character alphanumeric code that identifies the degree of degradation to mission capability and the system responsible for the degradation. The first character (alpha) is documented on the MAF. The second and third characters (numeric) are computer generated from the first two positions of the WUC. EOQ—End of Quarter. EOR—Equipment Operating Record. EOS—Equipment Out of Service—Nonoperational aircraft in relation to SCIR documentation. Those aircraft which are “OUT” of material condition reporting status and are reported in an inventory status code other than A. EQUIPAGE—The noninstalled articles, not usually associated with a specific model of aircraft, that make up the configuration on aircraft. Examples are life rafts, parachutes, safety belts, survival equipment, portable fire extinguishers, flight clothing, and similar items. AI-8
