MAINTENANCE MANUAL LINE
DEFINITION OF TERMS
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 misunderstanding and to
ensure safety:
• All time during which the engine is running is counted towards the total number of oper-
ating 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 relevant method
used.
NOTE
The planned inspections to be performed at certain intervals are based on experi-
ence from long test runs and field observations. They are intended as precaution-
ary maintenance measures in order to ensure continued trouble-free operation of
the engine.
TERMINOLOGY
The following terminology is used throughout this Manual, and the meanings are defined
as follows:
Inspection An inspection must be done only by certified mechanics who are approved on this engine,
using permitted procedures to make an analysis of the physical condition and find defects.
An inspection for condition and possible damage must be done in accordance with the ac-
cepted procedures for maintenance (refer to FAA “Advisory Circular” AC 43.13).
Check A check can be done by pilots and/or mechanics who are approved on this engine and
has examinations that compare condition with written standards to make sure of condition,
precision and tolerances.
Test A test is the operation of engine components, appliances or systems to make an analysis
of performance.
TIME LIMIT
Definition Time limits are predetermined time spans and intervals which are based either on calen-
dar 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 mainte-
nance work must be performed. These precautionary maintenance measures are de-
signed to avoid engine malfunctions or defects and ensure continued airworthiness of the
engine.
