|
|
I have an RV-7a with 700 hours on her and a month ago the flap fuse ( 7.5amps ) blew on two consecutive landings. The fuse has never blown before in those 700 hours. I know I was well below the white arc, 10 to 15 knots below, on both of the landings.
After I changed the fuse on those two, it went almost a month without ever happening again, then the fuse below twice more over the course of a few landings.
It always blows on the downward movement, but the point at which it’s blown varies anywhere between just barely having moved and being as much as 20 degrees when it happens.
The other point that someone is sure to ask is if it makes any unusual sounds during the travel… none what so ever, all appears fine on the ground.
I’ve scanned through the mailing list archives and couldn’t find any one reporting flap problems like this (apologies if I overlooked a discussion of exactly this problem), but I wondered if anyone could offer some advice.
Thanks,
Gene
