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.
