Once a helicopter ( or car - think about it) becomes stigmatised for whatever reasons, the value of pre-owned examples will suffer. The UK reader only has to think of the one remaining UK owned (at the moment) car manufacturer. However you polish the car - sorry - helicopter - the stigma will stick. The car - sorry helicopter - might be the greatest thing since toast and have bags of potential but its manufacturer's suppliers are simply no longer interested...they have moved on.
So you own an MD902 and would rather not. What is the best exit strategy? Well...I guess you extoll the virtues of the bird, tell the customer the wonderful job it does for you but also add that your role has changed....you need a bigger aircraft to embrace 'homeland' security or somesuch and just hope that your politicians will agree.
If it all goes the way it loos as though it will go, you will see a small specialised group of companies or even one company doing what Erikson did to the Skycrane...and what a job that was!
Its really difficult to sell something where everyone knows there is an issue but cannot admit it as doing so will dig an even bigger hole to the one they are already standing in. I've seen it in the corporate market where individuals stand to loose their own money if they pass ships on too quickly. So if you operate an MD902 with the police, take comfort that a least you personally do not bear the ownership costs - unless you are a community charge payer.
Another point you might dwell on. The MD902 was developed by a risk-sharing group of 20 or so in the Blue-Team. So what do they think (those who are left)? Kaman's position is fairly easy to read from PLC-type reports but what about Kawasaki who make the gearbox....and all the other suppliers.
So....get writing your new business case for that bigger helicopter with new capability and get those celebrated brokers out there to earn their not inconsiderable commission and sell the beastie before you get caught in the rush.
PS...Someone earlier said "smell the coffee...." That light at the end of the tunnel...its a train.....
