Time Between Overhauls (TBO):
The component in question must be removed at each interval that corresponds to the value indicated, in
order to undergo the operations in a specialized workshop that will enable it to be put back into service for
the next interval. A TBO is granted with a 10 % operational margin, limited at +300 hours. Some
subcomponents may have a Service Life Limit, rated above the TBO limit.
Service Life Limited (SLL):
The Service Life Limit is an airworthiness limit. The component in question must be removed from service
when it reaches the limit indicated.
