Hey Spunk you slimy devil (Great name !!)
I was staggered to read that you couldn't find an MEL for the 269 and after some digging around at my usual sources I have to agree with you !! How queer !!
As an ops manager this is a process I am currently going through myself, so can sympathise with your pain.
I am lucky insofar as for the fleet I operate a Master MEL (MMEL) is available for all types, on the CAA website - however NO 269 !!
A brief search through the FAA site also revealed a lack of info... BUT (and its a good looking but !) ... I did find the following site
http://www.opspecs.com/melpolicytalks/ which lists all the final policy letters for each ATA code, and with some head scratching and application to your own operation you may be able to produce your own (based on another known type).
Who knows - if it's good enough you may be able to sell it back to the Aviation Authorities who clearly think that nobody performs commercial ops in a H269 !!
Good luck.
Its always better to be pissed off than pissed on !!
