for the guys still scratching their heads on Torque values, ( i am frankly), attached is the table from the ASA aviaitoin mechanic handbook:

AN Bolt NUt bolt Tension
Size Size in-lbs

an3 1-32 20-25 add torque for nylock nuts to all

an4 1/4-28 50-70

an5 5/16-24 100- 140

an 6 3/8- 24 460-190

an 7 7/16-20 450- 500

after tyhat size we are getting to Boeing sized Nuts.
Other subject is the flaps. I was coming in for a landing and at 80 mph, set the flaps switch, as i trimmed, I kept compensating for heavier and heavier left wing. at 70 mph trimmed on 1/4 mile final, i looked and one flap was at 5 degree down and the other was full 20+ dgree down. the plane was still very controlable. I landed then reset the flaps. upon review the flaps came up when I broke the speed above 85 mph inadvertantly. the key is the plane did ot fall out of the sky, just kept flying it. says great things about the rougedness of the design.
solved the radio noise from the Jabiru engine. the saver was Resistor Spark PLugs. Size is DR9EA-9 on the Jab 3300. did the job.

Thanks Juan for that story about the flaps.

I have wondered what would happen if one flap was down and the other was not. What actually came loose? Mine have a bolt through the sleeve that connects the two sides.

Thanks again,

Hi Juan,

Could you tell us what exactly happened to cause the flaps to deploy
like that ? Did the torque tube pine come out of the slot ?

Thanks,

deplyed the flap at too high of a speed all the way to the last setting, and the pin came out of the slot.
