Not a dumb thumb, but an extremely aggro day to say the least. Took the Extra out for a few flights.
On my final, I did a go around because I didnt feel right about the landing. Came around, approached, and touched. As soon as my main gear touched the ground, airplane dead stoped, gear ripped out, spinner hit grass, and pushed firewall in over an inch. Myself as well as my spotter jsut looked at each other with the *** face.
Walk out, and low and behold there was a 6-6.5 inch deep sink hole that was about 2 foot round. Would you beleive that of all places to land, my gear had to land right inside of an un noticable hole from the flight line?
No pics to show, but aggro wasnt the word for it.
