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.
