1) Definition of terms
1.1) Operating hours
Definition
All of the maintenance intervals, such as the 100 hr. inspection and the
engine TBO, relate to the number of operating hours of the engine.
The operating hours are defined as follows in order to prevent misunder-
standings and to ensure safety:
- All time during which the engine is running is counted towards the total
number of operating hours.
- The time is counted irrespective of the load factor of the engine, such
as idling or take-off power.
NOTE: Maintenance and overhaul intervals are always dictated by the
readings of the engine control unit (ECU).
- The planned inspections to be performed at certain intervals are based
on experience from long test runs and field observations. They are
intended as precautionary maintenance measures in order to ensure
continued trouble-free operation of the engine.
1.2) Time limit
Definition
Time limits are predetermined time spans and intervals which are based
either on calendar intervals or the number of engine operating hours.
Once the time limits have been reached, the affected parts must either be
replaced for a general overhaul, or maintenance work must be per-
formed. These precautionary maintenance measures are designed to
avoid engine malfunctions or defects and ensure continued airworthiness
of the engine.
1.3) Life cycle
Definition
The life cycle is always specified as an exact time span and is also
quoted in flight hours.
NOTE: Parts with a limited life cycle must be taken out of operation and
overhauled or replaced if the specified time span or number of
flight hours is reached (whichever comes first).
