Maintenance:
 

Very small holes in the sail can be repaired with the sticky back tape. Damaged lines should 
be replaced by your Aircross dealer. 
 
Before fitting a replacement line, check it for length against its counterpart on the other side 
of the wing. When a line has been replaced, always inflate the glider on flat ground to check 
that everything is in order before flying. Major repairs, such as replacing panels, should only 
be carried out by the distributor or manufacturer.
 
You should also check for any damage to your lines, sail, risers and connectors before each 
flight.
 
After  excess  loads,  like  landing  in  trees,  etc   –  and  when  you  notice  a  change  of  flight 
behavior you should check your line lenghts .
 
To keep the operating licence for your glider a regular check has to be made.
 
After every 150 hours flying time or every 2 years, whichever is sooner, your glider has to be 
checked by the manufacturer or distributor.  Otherwise the warranty will extinguish.
 
If  you  wish  a  earlier  check,  e.g..  extreme  use  of  your  glider,  we  inform  you  about  the 
condition  of  your  glider  and  if  some  parts  will  need  to  be  checked  or  changed  before  the 
next normal service check period we will do this for you.
 

Disposal:
 

The synthetic materials used in a paraglider need a professional disposal.
Please send disused canopies back to AIRCROSS. 
We will demount and dispose them.
 
 

In conclusion:
 

The U FLY is at the forefront of modern paraglider design. You will enjoy many safe years of 
flying  with  your  U  FLY  if  you  look  after  it  correctly  and  adopt  a  mature  and  responsible 
approach to the demands and dangers flying can pose. 
 
It  must  be  clearly  understood  that  all  air  sports  are  potentially  dangerous  and  that  your 
safety  is  ultimately  dependent  upon  you.  We  strongly  urge  you  to  fly  safely. This  includes 
your  choice  of  flying  conditions  as  well  as  safety  margins  during  flying  manoeuvres.  We 
recommend once more that you only fly with a certified harness, reserve chute, and helmet.
