21.7 SERVICING AND REPAIRS
Any service or repair must take account of the risk of subsequent Propeller failure.
Therefore repairs are limited to the filling of small nicks in the Propeller. Maximum size of
nicks approved for repair is:
•
Those in Leading Edge: 4mm deep x 20mm long
•
Those across the drive Face (flat sides) : 2mm deep x 6mm diameter or
scratches not more than 0.5mm deep.
Repairs must also take account of the changes to balance of the Propeller and therefore
the Propeller should be removed in accordance with the procedure described above. It
must be checked for balance (see Paragraph 8) prior to refitting (see Paragraph 6),
checked for tracking after reassembly (see Paragraph 6.4) and the Spinner checked for
balance after reassembly (see Paragraph 6.7).
Only nicks within the size tolerances described above may be repaired. All propellers with
cracks or splits (or any delamination of the composite sheath in the case of sheathed
Propellers) must be either Rejected as unserviceable or returned to JABIRU Aircraft Pty
Ltd or our local approved agent for assessment and possible repair.
In composite leading edges, nicks of a size described above may be repaired by filling
with epoxy resin and Fibreflock using the procedure outlined below (Propeller Repair Kit is
available from JABIRU as Part No. PP0049N):
1.
Remove Propeller as per Paragraph 5.
2.
Sand nick with abrasive paper to remove any fractured particles.
3.
Mix resin carefully and thoroughly (equal parts resin and hardener) and thicken with
Fibreflock to form a paste.
4.
Apply paste to sanded nick and allow to cure in low moisture environment for 24
hours.
5.
Lightly and carefully sand excess cured resin to a smooth surface matching exactly
the previous aerofoil.
6.
Refurbish with clear Epoxy paint (JABIRU Part No. PP0069N).
7.
Rebalance Propeller (see Paragraph 8).
8.
Reassemble and replace Propeller and Spinner (see Paragraph 6).
9.
Check Propeller tracking and Spinner balance (see Paragraph 6).
10.
Damaged urethane leading edges should be referred to Jabiru Aircraft Pty Ltd for
repair.
