The rear fuse had an inspection hole cut in it but this compromised the structural integrity of the rear fuselage, So I have been told. Look at the foxbat SB on their website apropos the rudder cable replacement. I was told by a soar engineer, well he wore a soar jacket and said he was an engineer, they had developed a tool to replace those components but IMHO it was BS. Hence the new rear fuse as part of the YBSK auction. I was told by the horse it was over 35k to get it back in the air. Did anyone notice with numerous aircraft the similarity between leak down tests, i.e., 78/80 for every cylinder?
