--> RV9-List message posted by: "Merems" <merems@cox.net>
Gents,
I too am building an RV-7A and have been following the discussions about the recent
nosewheel collapse. I am concerned about this situation as many of you are.
I have talked with Ken Krueger (Van's engineering), who I have a tremendous respect
for, about some of these recent accidents. I am certain Van's Aircraft takes
this situation very seriously. However if you step back and ask yourself
are there a few RV'As out there that have had the highest number of landings
to date, where would you find them? What kind of landing have they seen? Grass
or paved runways? My best guess is these are the RV-7A and RV-9A prototypes
at Van's Aircraft. Who flies these? Van's staff. Where have they landed?
Grass or pavement? Both. Have they taxied on grass? Yes. Have they botched
a few landing? I would think so. Now I would bet these two aircraft have 10
times or more the numbers of landing then any another RV's out there and their
nose gears haven't collapsed.
I am not saying there isn't a issue, I am just giving you another view to understand
possibly why Van's Aircraft appears to have "no comment" when it comes to
this issue.
In all the postings about this issue, no one has mentioned the possibility of improper
heat treating of the gear leg. If I recall this was an issue sometime
ago with some main gear legs on RV's. This might be the root cause. This can
be easily determined by sending the nose gear leg off to any qualified machine
shop who can perform a hardness test on the leg. This will help determine
if the gear was heat treated properly.
Food for thought.
