5.4 General
From this stage on the engine will be divided into separate subassemblies and each subassembly will
be subjected to 3 distinct stages of inspection and assessment:
1. Check for mandatory update items
2. Cleaning
3. Inspection:
a. Visual
– scratches, burnt, bent, etc.
b. Dimensional
– precise measurements to spec
c. Structural
– MPI (Magnetic Particle Inspection) on steel parts
At the end of this process a single parts order can be placed with your local Jabiru dealer.
5.5 Mandatory updates
All engines must be checked for mandatory update items
– these are intended to bring older engines up
to the current specification and improve reliability and serviceability.
Mandatory updates must be performed during overhaul.
Refer to Section 12 for details.
5.6 Mandatory Discard
For some parts there are certain incidents which can result in hidden, internal damage - for example the
crankshaft of an engine which has had a severe prop strike. In these cases the part can be within
tolerances for wear and straightness and even test well with a MPI
– but experience has shown that the
part may fail if returned to service.
Any part for which this information is known will have a “Mandatory Discard” note in the inspection
section below.
