My advice on this is that when you test u/c retraction and deployment with
the plane on blocks (annual?) you simulate some back pressure on the
outriggers by pulling back on them with a bungee. I found that mine would latch
quite
happily when the plane was up on blocks, but in the air I didn't get the
reassuring 'clunk' until I slowed down to nearer landing speed. Backwards force
on the outriggers is proportional to square of the airspeed.
Testing on the ground they seemed to be fine, but not if you pulled them
back as the gear went down. Bit of adjustment and now they are fine.

The outriggers on my mono have never failed to latch but I have noticed that
if I lower the
gear/flaps/outriggers at just under flap speed, the outriggers do not
audibly latch in the down
position until approx 70 mph. I'm wondering if the down latch springs are
getting tired after 6 yrs or so?

Hi Nigel,
It would be of high interest for all monowheel operators to know the root
cause of your mishap. As long as the reason is not identified it may happen to
you again! I believe there should be a way to reproduce the unlatched
outrigger problem on the ground and find out what is wrong in your outrigger
mechanism.
Best regards

Nigel,
Have you managed to ascertain why your Outrigger failed to latched.
Await your judgement.
Peter.
