Before beginning the step-by-step inspection, start, run-up and shut-down the engine in
accordance with instructions in the Flight Manual.
Before starting, ensure the aircraft is suitably positioned. Aircraft must be:
-
Oriented into wind
-
Positioned where there is no long grass, loose gravel, sticks or dirt under the propeller.
-
Positioned where the wash from the propeller will not blow into hangars, at aircraft or
personnel etc.
-
Positioned where there is sufficient space to regain control of the aircraft in the event of
brake failure.
-
Positioned with consideration to other personnel
– i.e. where noise impacts are minimised.
During the run-up, observe the following, making note of any discrepancies or abnormalities:
-
Engine temperatures and pressures.
-
Static RPM within limits of Section 3.5.
-
Magneto drop within limits of Section 3.13.
-
Engine response to changes in power.
-
Any unusual engine noises.
-
Fuel shut-off valve; operate engine in ON position and in OFF position long enough to
ensure shut-off functions properly.
-
Idling speed within limits of Section 3.10.1.
After the inspection has been completed, an engine run-up should again be performed to
determine that any discrepancies or abnormalities have been corrected.
WARNING
Engine runs on the ground must be short to avoid over-heating engine. Monitor engine
temperatures carefully during ground test runs.
Test runs are to be carried out by appropriately trained, authorised personnel only

Locate a fixed object on a flat floor so that it just clears the propeller tips when rotating the
Propeller by hand.
Check that each blade clears the object by the same amount.
If the Propeller is outside the approved tolerance, refer to JABIRU Aircraft Pty Ltd or our local
approved representative.
Blade tracking tolerance will normally be supplied by the propeller manufacturer. For Jabiru
wooden propellers the Tracking Error Tolerance is +/- 2mm.
