Just wondering if there will be a hush kit released before next week for the NAMC YS-11's. I have been replacing them but not all of them will be replaced for several more years. I noticed that even the Vickers Viscount 840 from the 50's has a hush kit but not the currently in service YS-11.

Don't remember when it's released, but before any noise regulations actually kick in anyway which is around year 2000 for the chapter 3 requirement (= which does not come next week).
