you're not doing it for the pay then that shouldn't matter,eh?!?

Lot of variables....the northeast can have people leaving just because of the geographical area because they want to go to the Carolinas or Florida and it doesnt matter how good the job is.  Other times leaving a good job is because of bad management, all it takes is one bad manager that you have to deal with on a constant basis and it can ruin an otherwise good job.  The other problem is the Northeast is expensive to live in, so even 120-150k can be a problem unless you want to drive over an hour and a half to work.  Boston Medflight has that problem, while base pay is above average, the housing market in the metrowest area of Boston is very high so you have to get fairly far away depending on what base it is to get something affordable.  Now I dont know exactly where you are talking about of course, could be NYC, NJ, CT/MA or way up north in the VT NH ME but those are all very different markets.  Poor maintenance or equipment can be a put off too.  Any other details?

I forgot to ask but are you conducting exit interviews? Of the 50 pilots who left what have they been saying was the reason? Another kicker is when you operate in an area with lots of other helicopter jobs there is always something else to move on to, you may run a nice place but if you got a pilot who really wants to fly a 139 and you don't operate one then they are out the door. The northeast has lots of opportunities to fly just about anything and most missions. If you were the only game in town then people who grew up in that area and fly are gonna be lifers. I know you can say who you work for but it feels like BMF, I know it's a revolving door up there despite having very nice aircraft and a great culture. The DHART guys have the very low cost of living helping them and the quiet life that is mainly up there goes for Lifeflight of Maine too. Once you get down in the Umass and Hartford Lifestar programs you are dealing with low pay and typica AMC nonsense that would leave very little doubt as to why folks leave to go fly Bob Kraft or any number of the corporate places up there where 200k starts becoming an option 

VERY high cost of living in that area, no state tax? yep, but they tax the crap out of you for everything else. A shack within 1 hrs drive of the base will cost you 200K + More bang for your buck elsewhere.

  50 pilots in 20 years inst too bad. I'd guess in a 8-10 helicopter  operation in utility over 20 years that number would be in the 100's.  Schedule, money and disorganization is what makes most of us drift around.

Not to forget the lead pilots are involved on many fronts trying to get laid.  Medcrew are even worse.  Management creates more and more paperwork and stupid requirements. 

ur probably 50.  Hope you have corporate doors open if you decide to go that direction.
