The manual prop spin, cowls and clutch switches are usually the problem in the AN-2 and if not set as per the checklist: the engine will jam/seize after flying for a few minutes and there are a few more failures.
IE:
Engine failure: Fail to do manual rotation of propeller (button 5): 20% possibility to fail after start
Engine Failure: User sees message "Water!" after sump drain procedure 6 - 10 seconds hold): 5% possibility of engine, repeat draining to remove water
Engine Failure: Engine overheat when conditions apply
Pitot Fail: If airplane has speed less than 60 km/h more than 10 minutes (failure will happen in 10-20 minutes range)
Lights Failure: If landing lights work more than 8 minutes (failure will happen in 8-16 minutes range)
But think you can bypass: Try this:
Go to the an2.ini file (In root folder of OctopusG_An-2). Open that .ini file with notepad:
[simconnect]
; version=
[an2]
failures=1
[insects]
count=1
probability=0.60
slapsToKillMin=3
slapsToKillMax=7
The failures line: Default value reads: failures=1 (which is failures on). Replace the 1 with 0 (so failures=0) and save the file. This should turn off the failures in the AN-2. Maybe!!
Hope it works for you?
Here is a quick vide on the AN-2:
