Narrative:

Several times now; including last weekend when landing at dona ana airport at santa teresa; NM (5t6) I have experienced an airport condition which put my flight at risk and I have noticed other aircraft experience the same thing. You will be delighted to know that is a problem which will be exceedingly simple to remedy and will result in much greater safety at this airport.here is an account of what happened this weekend:I listened into the CTAF 122.725 for traffic and superawos reports; beginning 30 miles out. People were triple-clicking the mic so the surface conditions were heard every couple minutes. In each case; the wind part of the superawos was saying winds out of the southwest which would favor runway 28. It was saying 200 deg to 250 deg and up to 15kts. I announced my intention to use 28 based on this information. As I approached; I noticed 5 aircraft in the pattern announcing the use of runway 10. I queried the other pilots as to why they were using 10 when the wind report strongly suggested 28. One pilot said the AWOS never works and the wind was actually favoring 10. I merged into the pattern and while landing; noted the windsock was a southeast wind; probably 160deg at 10kts.my mistake in all this was to forget that the AWOS was reporting the opposite direction wind; during another trip to 5t6 many months ago. I landed downwind and it was not pretty. I assumed that a responsible airport authority would have been monitoring this; or have been told of the problem long ago. Here is my simple suggestion: make the 5t6 airport shut the thing off if they are not going to fix it. If the AWOS is silent; pilots are going to take other reasonable actions to ascertain the wind direction. With the AWOS actively giving misinformation; this is a pilot trap! While I was servicing the airplane; I watched a cirrus land on runway 28 and he used about 5000 feet of runway because he landed downwind as well. This is a very windy airport and disregarding this problem will lead to problems.please call the airport manager and have the superawos shut off today if they refuse to get it fixed!

I merged into the pattern and while landing; noted the windsock was a SE wind; probably 160deg at 10kts.My mistake in all this was to forget that the AWOS was reporting the OPPOSITE direction wind; during another trip to 5T6 many months ago. I landed downwind and it was not pretty. I assumed that a responsible airport authority would have been monitoring this; or have been told of the problem long ago.
