Thanks for the input 1Consultant, unfortunatley with an ageing fleet of F28 aircraft,spares come at a premium, and the vendor has a monopoly.
Our Engineering manager has been in touch with the vendor and its pretty much up to us to keep paying for their dwindling stocks, and not for their jurrasic R and D.
We will investigate your suggestions, hopefully with some positive results.
Any other F28 operators willing to comment?
