FCU Bendix Start
Bought 6 weeks ago a second hand Bendix FCU ex US with 8130 certification as a complete kit to replace our ceco unit. Paid USD15K. When it arrived, it was missing some fitting parts which I had to request again, took another 2 weeks. When installed, the FCU unit was leaking over the starter unit. Sent back for checking by an ovh shop in the US (at seller cost) came back 7 days later, no more leak but now hanging at 50% N1; if I release the ident and pass the click, then the N1 will increase and stabilise at 64%. If we adjust it, it drops down to 58%. Next start it's back at 64% idle...
Then if u slowly open the throttle from idle, it suddenly surges up to 104%N1, then stabilises at 100%.
The engineers are saying this FCU is faulty;if we take it off, and put another FCU on, no starting problem occurs...
I am not getting much help from the seller anymore; Any suggestion?
