Gin Boomerang12, User Manual

 Boomerang 12 user manual 

 _____________________________________________________________________________________________________________________________________ 

●

 a trim check should be performed during the 

fi

rst 12 months by an authorized GIN agent 

●

 we recommend replacing the line set at least every 150 hours 

 Ground handling time must be at least doubled when calculating the total hours of use because of 

 the increased wear and tear on the glider. 

 If you use the Boomerang 12 in harsh conditions (sand, dust, stones etc.), we recommend a biannual 

 check. 

 Additional inspections should be performed following a crash or violent landing on the leading 

 edge, or if you note a deterioration of performance or behaviour. 

 The condition of all components and materials must be checked with the utmost accuracy during 

 testing in accordance with the GIN inspection instructions. These results, and an overall assessment 
 of the condition, are part of the check log. 

 Service and repair shops authorized by Gin Gliders are in possession of the Gin Gliders inspection 

 instruction, which contains all the necessary procedures, equipment and additional technical 
 information about the Boomerang 12, such as single line lengths, sewing and further material and 
 processing guidelines. 

 It is very important that your glider is serviced at the required intervals throughout its entire life. In 
 order to bene

fi

t from Gin Gliders warranty: 

●

 You must have your paraglider inspected by Gin Gliders or an inspection agent authorised by 
 Gin Gliders. 

●

 The documentation and the result of the inspection must be clearly identi

fi

able (date and 

 place / name of the inspector) and be entered near the glider information/certi

fi

cation sticker. 

 Pilots are able to carry out the inspections themselves or appoint a third party to do so (e.g. 

 manufacturer/importer), provided that the requirements are all ful

fi

lled. However, if this is done, the 

 liability and warranty of Gin Gliders will lapse. 

 GIN and the commissioned test laboratory recommends that inspection is carried out by the 

 manufacturer/importer or by an authorised inspection agent. 

 The Boomerang 12 is trimmed to give the highest possible level of performance and safety. The 
 aramid lines may shrink or stretch in normal use and particularly after hard shock rein

fl

ations. 

 Pilots should check that the lines remain within tolerance. The Boomerang 12 is certi

fi

ed with the 

 lines trimmed so that the total line length from tab to riser is within 2 cm of the values stated in the 
 line-plan. The lines must be measured with a load of 5 kg, in order to ensure reproducible results for a 
 comparison with the lengths in the check sheets. 

 Due to different measuring systems and calibration, there is a possibility of a difference in the 

 absolute line lengths. In this case, the measured values should 

fi

rst be corrected to the same base of 

 the Boomerang 12 check sheet data. Correct line length and symmetry are important for performance, 
 handling and have a considerable in

fl

uence on 

fl

ight behavior. 

 If the lines are more than 2 cm out of tolerance they should be replaced. If the lines are less than 2 

 cm out of tolerance they can be re-trimmed either by taking (or releasing) loops on the Maillons or by 
 adding an extended Maillon. Contact your dealer or Gin Gliders for details of how to retrim your glider.
