Wondering if anyone with a IVP has had this problem.....
Our flaps work well on the ground, but in flight, on final approach when we
select full down (around 120K), they stop at around 30 degrees. After touch
down, as we are slowing, the final 10 degrees come down.
We have tried....tweaking hydraulic pressure to 1250
             ....loosening up the rollers by backing off the nuts
             ....various lubricants on the rollers and guides
             ....even replaced the regulating valve
At the moment, the hydraulic ram pushes the bell crank hard against the gear
box assembly. There is slight (minimal) deflection in the box as the gear is
fully retracted and we are not sure if we are comfortable with this, however
have had to do this to get 40 degrees down movement.
Any suggestions as to where we should be looking or how we should be doing
it differently?
