Then...when you get to the twin Cessna flap design, cable tensions, chain adjustment, micro switches galore, four flap sections, rod ends, bell cranks, torque links, etc...all must be in alignment, and adjusted properly, in conformity with the maintenance and service manual.
Figure eight hours mechanic time, at the minimum.
However, when completed, the system is very reliable and trouble-free.
No 'floopy flap', either.
