Hi Guys

This problem was observed mostly on the earlier hotpsots. The glue joint on the trailing edge of the fusalage is a blind joint (thats what I was tols by one of its original test pilots). Later ones have this joint beefed up. As miniflyer correctly stated above it was caused by air entering the rear wheel wells and creating possitive presure within the fusalage. The rectification was, as again correctly stated by miniflyer, to drill holes or slots along the bottom trailing edge of the fusalage or use gear doors.

Regards

Paul
