nigelh, you have an AOG center in the UK. Call +44 (0) 1935 702866 (5am to 10pm) or 7741 036307 (10pm to 6am).
I must stress that these parts are FREE. If you are being charged for the parts, then something is very wrong. Mandatory Bulletins - Parts are free. Optoinal Bulletins - Operator purchases parts. That is always true for Agusta.
The phone is mightier than the email!
