The squeaky bearing gets the grease.
I know it took months to get the rear canopy bug fixed, even after several posts that showed a repeatable problem and the simple fix for it, even.
A proper bug report, with caps in the title has to be submitted and supported by others, which is hard as only a few people fly the 39, and also a polite PM or two is sent until an answer is provided one way or another.
I would be posting bugs if I was flying, but life has me month's away from that for now.
