Maintenance  

 
Occasionally, the starting unit clutch may slip or not grip properly, the result of dust and 
oil sediment on the compressor nut.  The O-ring and compressor nut should be cleaned 
periodically, with a cotton swap and solvent.  When the turbine is not running, the starter 
may be tested by pressing the 

IGNITION

 key on the GSU.  

 
Check your fuel filters every ten (10) flights. 
 
Each 

JetCat 

has a prescribed maintenance interval.  After approximately 25 hours, the 

engine should be returned to 

JETCAT USA

 (along with the ECU and fuel pump), for 

service.  The total running time of the turbine can be accessed and monitored through 
the 

STATISTIC

 menu.
