yes the flap actuator on the IV is critically similar, with the only 
difference being if it fails the crank, you probably dump the whole airplane. 
 Additionally, the crank itself has an engineering defficiency which, to my 
knowledge has never been publicly acknowledged by the factory.  You know, the 
poopoo factor......when the hydraulic ram is extended and retracted, it can 
strike one of the push rods to the flap.

Have your day made by finding a deep groove worn into your pushrod 
tube.....and we knew it was close to interferring, so we checked and 
rechecked it by using paper shims as a feeler guage.  After a period of time 
the clearance disappeared and we got grooves worn in the side of the push rod 
tubing......not a nice sight.

Hey Lancair, how about admitting and addressing this problem before someone 
is killed?  Your new potential insurance carrier wont hang around long if 
people start dying......the poopoo factor is going to come back and bite you 
in the ass someday.

Have a nice day flying everyone....is your child sitting above that bell 
crank that might have grooves in the flap pushrod tube?

And don't anyone from the factory contact me and tell me to tone down my 
criticism--I will not have any of it--I have seen too many guys die from 
stupid engineering lately.You are aware of this problem, have not addressed 
it, and when it kills someone, you are liable.   Have a nice day.
