Daily Inspection

 continued 

6. Cockpit 
-

 

Canopy cleaned, if necessary 

-

 

Proper function of canopy locking and emergency release (not daily, but to be 
completed at minimum every 3 months): 
a)

 

"Pilot" in seat, both canopy locking handles opened. One person at the front 
end to lift the canopy from the fuselage. 

b)

 

After puling the emergency canopy release handle the pilot pushes the canopy 
up at the rear to disengage the LS-Latch (Röger hook) from the spring on the 
fuselage. 

After pulling the emergency canopy release handle the canopy must be freely 
moveable at the front. 

With TN4032 executed:

 The canopy must be lifted at the front by the spring at the 

hinge by about 60 mm <2.4 in.>.

 

c)

 

Then the pilot lifts the canopy at the rear end up as far as possible, the person 
at the front end holds the canopy. 

Caution:

 The person at the front end should not lift the canopy too far up. Otherwise this 

would unduly deform the spring of the LS-Latch (Röger hook) located at the fuselage. 

Note:

 b) and “Caution*” apply only if TN 4032 LS-Latch (Röger Hook) has been 

completed 

Reinstalling the canopy: 

2 persons are needed  

a)

 

Pull up the canopy hinge to the open position.  

b)

 

One person (at the front end) holds with one hand the emergency release lock 
in open position (rotate clockwise) and places the canopy with the other hand 
onto the hinge. The other person holds the canopy at the rear end so far up 
that it matches the canopy hinge. 

c)

 

The front person engages the canopy by turning the emergency release lock 
anti-clockwise to the stop. 

With TN4032 executed: 

The spring fixed at the canopy must be inserted into the 

ring at the canopy lifting mechanism. When pressing down the canopy make sure 
that the spring doesn’t buckle.

 

-
