Currently, the old manufacturer of the part confirm to us and our authority that they are no more certified to do overhaul of this component with the issue of EASA Form 1, and we currently had lead times of 9 months and 5000 euros in advance.
Our new valve is currently installed and certified on the first aircraft and is available to extend applicability on request.
We are the only authorized shop that is authorized to do the modification.
After this mod, the valve maintenance will be easy to do and is almost ON CONDITION.
No more TBO.
And if repair is needed, O-rings are MS standard and repair kit is available commercially.
I hope you can inform F260 community if they need assistance for this part very hard to find. STC costs were high for us but we can try to do a average cost depending on requests.
