I have zero time in firefighting. Friend of mine who does says that there are some changes coming. He says that soon, "Type 1's" will all have to be manufactured after 1990. I guess that will put a bunch of current a/c out of the game? So long, Vertol 107s and S-61's? And Type 2's are all going to have to be twins *and* manufactured after 1990? Like I say, I'm not in that segment, but if what he says is true, it sounds like these new requirements could mean big changes in the fleet. Any elaboration from those in the know?

Stay in your lane and leave the real work to us.

Is it that you cannot answer the question, or that you will not for some bizarre reason?  If what my friend says is true - that all Type 1's have to be manufactured after 1990 (and be in production), then that's going to put a lot of "legacy" Type 1's out of the game. Good-bye Crane, hello Puma? (I guess.) Similar rules for Type 's? See ya, old 205/UH-1's. This could mean big changes for operators that work for the USFS. 

Cranes good at fires, as well as other "legacy" aircraft. Tell your "friend" to do more research before opening his mouth.

Type 1 EU contract wants 1990 or newer

Type 2 doesn't say any thing (can't find a substitute for 205...)

Type 3 EU 2000 or newer

I wish all helicopter pilots were like you, instead of the bitter, angry malcontents that usually inhabit this site. If that other guy didn't know, why didn't he just say so, instead of coming off like a complete AH?  

I tried to post the official USFS docs for you. Doesn't seem it passes the filter

Which is why I said let the real mean talk cause if you friend knew what he was talking about he would have read the MATOC and knew the type 1s doing suppression wouldn't be eliminated.

Guess I missed the one on the Type 2s having to be 2014 or newer, but it only applies to twin engine aircraft if it is marked on page 2 as T. That MATOC is a pain to read thru.
