RECOMMENDED COMPONENT LIFE

The safe working life of the structural components of the Java is dictated by the 
environment in which the aircraft is used and the care taken during day to day 
operations.  Inspection, therefore, is an essential tool in deciding the continued use of 
most components, particularly the sail.  Due to the nature of their material, 
construction and position within the structure, certain components have a critical 
fatigue life and it is mandatory that these components are replaced within the time 
stated below.

Cross Tubes

2000 hours

Leading Edges

1000 hours

Control frame / fittings

1000 hours

Keel

1000 hours

Rigging wires / Tension strop  200 hours
Factory inspection 

  100 hours or 1 year (See maintenance)

REPAIR

Warning:

  The Java  airframe is deceptively simple, but like all aircraft requires 

skilled and qualified attention.  We do not recommend self repair or re-assembly by 
other than Avian or Avian nominated repair agents.  No replacement parts should be 
fitted unless they are factory supplied and identified as such. 
Repairs should only be undertaken by Avian approved personnel.
Sail repairs are only to be undertaken by the Avian factory.
Repairs of all other parts by replacement only.
Replacement parts must be obtained from Avian Ltd. or an Avian Ltd. appointed 
agency to ensure that they are genuine.
When ordering spares always quote your glider number (make a note of it if you have
to replace your keel).
Bent aluminium tubes must never be straightened, always replaced.  Frayed cables 
and cables with damaged or twisted thimbles must always be replaced.

To help you identify components some of the main assemblies are shown in the 
appendix of this manual.                  
  

TRANSPORTATION AND STORAGE

Storage general

The glider should always be stored:

WELL PACKED
COMPLETELY DRY
WELL SUPPORTED
IN A DARK, COOL AND DRY PLACE.
