The engine retraction limit switch used to date is no longer available. Technical Note DG-SS-11 / 800-53 authorizes an alternative retraction limit switch.
In addition, as part of the TN, the glass-tube fuses may optionally be replaced with circuit breakers, as modern avionics systems require more current. These two changes, along with various other manual corrections, result in updates to the flight and maintenance manuals.
The TNs and the corresponding conversion kits are now available on our website and in our online shop.
