By the way, the "damage" was the result of a design fault in the nose gear
extension mechanism, not a result of excessive speed on climbout.

The damage was caused by fast retraction of the nose gear on take-off (because
of the weak cylinder against building airspeed); the solution to that one was
to fit a restrictor in the hydraulic 'up' line. Any other problems were linked
to, but not the cause of, the damage.

The NAA logs are quite detaioled on this.

According to Roy Ferrin, the actuator was replaced with one having a
larger diameter piston, and the door linkage was adjusted to close a tad sooner.
I can't see how a flow restrictor in the line will compensate for a lack of
force resulting from inadequate pressure area. If you want more push for a given
hydraulic pressure, you need a larger cylinder.
