My one year old Sigma-tec vacuum pump went out the other day, blew a hole in
the case. This unit was supposed to be good for 2000 hours or five years.
The company is going to warrantee it with a standard pump. They said they
made the changes and have the other units on back order waiting for
certification. I guess they are not so good.
I was lucky it happened at an airport where a friend let me fly is V tail
bonanza home. How lucky is that.
