SAFETY ALERT SR/Moose Quick Build
Posted: Sat Feb 18, 2012 9:54 am
All:
For those of you who have a Moose or Super Rebel quick build, do not rivet
the intact leading edges of the ailerons and flaps without fully opening
the skins.
Since in the US, we do not have to have open inspections, I did not remove
the external temporary rivets on the skin until I riveted the whole leader
edge skin of these four pieces. I did, of course, replace the external
temporary rivets with permanent rivets and removed the center cover to
assemble the center hinge point.
The big problem is that the folks in the Philippines decided to use
sometimes one or two temporary rivets and sometimes a cleco to attache the
all the ribs to the spars (not just the center ones where the center hinge
bushing is installed). I didn't check this since I could not fathom that
they would fully rivet the aft ribs to the skin without having permanent
rivets in the spar to hold the ribs.
This obviously is a major safety issue if someone starts flying and the
ribs are not secured to the spar properly. I have discussed this with
Robin at MAM and he is talking to Darryl about it to see what to do. By
the way, in addition, on the ailerons, there was a temporary riveted double
at the middle hinge point but this was left out on the flaps which MAM is
now charging me to replace (another source of irritation). There seems to
be no rhyme or reason to what is riveted permanently and what is not.
Although I am a first time builder (and I suspect most quick build folks
are), I would be interested in hearing if I am the only dingbat who didn't
check this out given full riveted aft skin and no quick build
documentation. I can't tell you the amount of wasted time, frustration,
and dealing with oversized drilled out rivet holes this has caused.
