INSPECTION
For specific items to be inspected and for periodic inspection details, refer to Engine
Instruction & Maintenance Manual.
1.
Visually inspect the engine for loose bolts, nuts, cracks, leaks & cooling fin damage.
2.
Inspect baffles, baffle seals & brackets for cracks, deterioration or damage.
3.
Inspect hoses for internal swelling, chafing, cuts, breaks, stiffness or loose
connections. Excessive heat on hoses will cause them to become brittle & easily
broken. Hoses are most likely to crack or break near the ends & at support points.
Check fire sleeves on fuel lines within the engine compartment.
NOTE:
Avoid excessive flexing & sharp bends when examining hoses for stiffness.
4.
All flexible hoses in the engine compartment should be replaced at engine overhaul
or every 2 years whichever comes first. Hoses which show visible deterioration
(cracking, excessive hardening) should be replaced immediately, irrespective of
age.
5.
For major engine repairs, refer to JABIRU AIRCRAFT Pty Ltd or an Approved
Jabiru Service Centre.
11.2.5.1
FLEXIBLE HOSES
Leak Test
•
After each 100 hours of operation, flexible hoses should be checked for leaks.
•
Examine the exterior of hoses for evidence of leakage or wetness.
•
Replace any doubtful hoses.
Replacement
•
Hoses should not be twisted on installation.
•
Provide as large a bend radius as possible.
•
Hoses should have a minimum of 12mm clearance from other hoses or surrounding
objects or be tie-clamped to them.
NOTE:
Rubber hoses will take a permanent set during extended use in service.
Straightening a hose with a bend having a permanent set will result in hose
cracking. Care should be taken during removal so that hose is not bent
excessively, and during reinstallation to assure hose is returned to its original
position.
