MAINTENANCE MANUAL LINE
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.
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 if the
specified time span or number of flight hours is reached (whichever comes first).
GENERAL OVERHAUL (TBO)
Definition The time between overhauls (TBO) for all objects (such as the engine, component assem-
blies, add-on components) is the approved length of operation under normal operating
conditions before it becomes mandatory to send in these objects for an overhaul.
Normal operating conditions are the conditions which comply with the manufacturer's and
the aviation authority’s recommendations for the certification of airworthiness.
Maintenance of
operation
The TBO values approved by the relevant authorities are based on performance tests and
empirical values which have been gathered through operation of the engine and are re-
quired for the acceptance and certification of airworthiness. TBO values can be changed
in response to possible upgrade/expansion programs.
Legal obligation
to keep
TBO values for the engine are always shown in operating hours and years. The user must
record the operating hours in the engine log book.
PURGING THE OIL SYSTEM
General note Purging of the oil system is extremely important for operation and service life of the engine
and therefore the procedure must be followed meticulously.
