Graham,
Done that! Been there! I did not have the spring on the down latch and someh
ow the latch flicked up on landing allowing the lever to come out and go for
ward the way you describe.
Consulting my licensed engineer I only needed to replace props, repair damag
e to tunnel and wing where one of the props hit. I did not need to do anythi
ng with the Rotax 912S as there was no load on the engine at the time. Had t
o get the airmaster prop hub crack tested. All happened in slow motion! Thir
d flight so very disheartened however the aircraft main wheel and outriggers
kept the fuselage off the grass runway preventing further damage. Good desi
gn feature!

t would seem that a great load has been put on the retraction lever indicati
ng that the mechanism was not in the over centre position when the lever was
in the down and locked detent. This is something that should be carefully c
hecked during set up and during servicing checks. I am very sorry for Jeff a
s it looks a lovely aircraft but it should be quite easy to repair. Remember
to send me some pictures for the Europa Flyer when she is flying again

ways, any ideas or has anyone else out there suffered the same problem? Dur
ing my build I definitely was concerned that the "Gear" handle was doing 3 j

as been on the mains since last September and has been moved in and out of t
he hanger many times, what gives besides the gear? I have attached some pic
tures that may shed some light to your experienced eye.

afety latches for the landing gear on the aircraft appeared to be functionin
g and engaged as designed. Aircraft dismantled and stored in owners hanger, p
ending review of damage.
