This is what I did to make this map work in 4.12.2 ModAct 5.3.
1A) Install the version found in the first page (forget about the LALRone's hangar mod)
1B) Optionally, overwrite with the the last version from SAS~Tom2 (Reply 101)
2) Now, I run the Universal static.ini Checker and it found 9 missing objects. Instead of downloading and installing these objects, I replaced them with some stock barrels:
Add the following to the end of your static.ini found at \#SAS\STD\com\maddox\il2\objects\static.ini:

You will have some hangars and other objects replaced with a bunch of barrels. This seems the best approach to quickly have more maps working without worrying about missing objects!
