Normal Procedures 

4.1.

 

General 

This  chapter  deals  with  the  normal  procedures  recommended  for  the  safe 
operation of the FK 9. 

4.2.

 

Regular Inspection 

As Ultralight aircraft are designed to be lighter than normal aircraft but must 
withstand  similiar  loads,  the  structure  and  the  engine  must  be  inspected 
regularly. 
If there is any damage it is recommended to consult a certified maintenance 
facility or contact the manufacturer. This applies especially to the composite 
and aluminium structures. 

4.3.

 

Preflight Inspection 

During  preflight  inspection,  the  aircraft  must  be  inspected  for  its  general 
condition.  Snow,  ice,  frost  and  dirt  must  be  removed  completely  from  the 
aircraft as they impair aerodynamics and also increase weight. 
 

Items marked by * must be performed prior first flight of the day only.
