Propeller
– Inspection Details
The items listed below provide additional details for the numbered inspection items in Table 13.
These basic requirements must be carried out in conjunction with any other maintenance
requirements required by the propeller manufacturer. See Section 8.14 when operating with a
non-approved propeller type.
As all possible circumstances cannot be listed here, the following is provided as guidance only.
A critical, trained eye is required and inspections should include, but not be limited to, the
following.
1. Spinner: Remove & inspect for damage or wear.
2. Spinner Mount Plates: Inspect for damage or wear. Ensure anchor nuts are secure and in
good condition.
3. Spinner Screws: Inspect. Ensure all are in good condition.
4. Propeller: Inspect for damage: nicks, cracks, fretting, corrosion, fibreglass de-lamination,
stone or rain damage.
5. Propeller Tracking: Check using the procedure given in Section 9.2.
6. Propeller Bolts: Check to the torque setting given by the propeller manufacturer. For Jabiru
Aircraft wooden propellers the torque settings are given in Table 10. This is to be done
simultaneously with the propeller tracking check.
7. Spinner Tracking: Check using the procedure given in Section 9.2.

Engine & Engine Compartment
– Inspection Details
The items listed below provide additional details for the numbered inspection items in Table 13.
As all possible circumstances cannot be listed here, the following is provided as guidance only.
A critical, trained eye is required and inspections should include, but not be limited to, the
following.
1. Engine Pre-Inspection Test Run: As noted above, test run engine before maintenance to
check for abnormalities. If oil pressure is outside limits it may be corrected by adjusting the
oil pressure relief valve per Section 9.6.
2. Engine Cowlings & Fasteners: Remove & check for damage or wear. Particularly inspect
the areas around the inlets and outlets for excess gaps between the cowl and the cooler /
engine (generally any g
ap that two “average” fingers will fit through is considered
excessive) or for indications that the cowl is rubbing on the engine, oil cooler or exhaust.
Rubbing will produce excess vibrations and can damage parts (such as the oil cooler etc).
Check that fasteners are fitting firmly and are not worn or damaged.
3. Inspection of Engine & Compartment
– Pre Cleaning. It is recommended that the engine
compartment be visually inspected twice: once while “dirty” – i.e. fresh from operation – and
again after cleani
ng. The “dirty” inspection allows the inspector to see patterns of leakage
etc which are lost when the engine compartment is cleaned while the “clean” inspection
may show items which were obscured by “dirt” previously. The engine and engine
compartment must be cleaned in accordance with Section 7.3 as a part of inspections &
maintenance where noted in Table 13 above.
4. Clean Engine & Compartment: In accordance with Section 7.3
5. Inspection of Engine Compartment
– Clean: Check for damage or wear which may have
been obscured by dirt etc during the “dirty” inspection. Thoroughly inspect the engine for
missing or loose bolts, nuts, pins etc. Carefully inspect the Torque Seal anti-tamper
compound on all fasteners, including the through-bolts. Cracking or failure of the
compound indicates a loss of tension which must be corrected in consultation with the
engine overhaul manual.
6. Check flywheel screw tensions as detailed in Section 9.23: This inspection is to confirm
that the flywheel screws are intact and sufficiently tight. If any screws rotate the rectification
work detailed in Section 9.23 must be carried out.
7. Carburettor air filter: Check & replace if required.
8. Carburettor air filter: Replace at the interval noted.
9. Engine baffles and air ducts: Inspect for damage and wear. Particularly ensure that the
screws holding the ducts to the engine are secure
– failure of this connection can result in
