I had a long talk with a engineer that helped design the MKIII and he would not budge on the recommended 1000 LB limit. Yes the airframe is very strong and is conservatively rated as all aircraft are. His concerns are things like builders skill, aging airframe, and turbulent air. At least one builder/pilot flies his plane loaded to 1200 lb. but only after a number of modifications to the airframe. Without a extensive background in aircraft design and considerable testing it is dangerous to recommend exceeding the manufacturer's limits.

I have been told by a very good source that 55 to 50 (no flaps) is normal for a Mark III Xtra. Mine is in that range. If that is the case 50 is not a good pattern speed.

Powder coating steel typically involves a phosphoric acid cleaning, the powder is applied by electrostatic deposition and then baked to fuse the powder into a continuous plastic coating. Therein lies the problem, once the coating is pierced in any way, or if the phosphoric acid dip is eliminated or too long a time passes between the dip and the coating operation corrosion is sealed under the coating and the staining shown in your pictures results. Up to you as to how you repair it but AC 43-13 1b is a good place to start.

________________________________ Message 11 ____________________________________ Time: 06:28:48 PM PST US Subject: Kolb-List: Re: Mark III POH From: "Rex Rodebush" I also thought 55 was too high for stall. I pulled the static line from the tube and put it inside the cockpit and but got the same result. The next thing is to get some good test data with the indicated airspeed and actual GPS speed. I've got about 4 hours on the plane but am waiting for a new fuel pump as mine was on the recent Rotax service notice. My pitot tube is about 6" down from the nose and about 2" left.
