FUS-30 DAMAGE/REPAIR
Posted: Fri Feb 17, 2012 9:17 pm
Thought I would let everyone know that I have posted 3 pictures to the
Rebel-Fuselage "file".
Many builders in the past few years have asked if there was any positive
proof for the need to reinforce the FUS-30, from in front of the tail spring
attach bulkhead to the fin tailpost, as Bob and myself have been suggesting
to all the builders we've had the privilege to meet/greet over the past MANY
years. I have uploaded the pictures so you don't have to take our word for
it anymore!! Two recent aircraft through my shop have allowed me to get some
shots.
One picture shows a buckled FUS-30. The reinforcement shown in the picture
that was installed by the builder(s) was useless, as it was installed
between the spring attach bulkhead (SAB) and the TS-1's. It did not overlap
the tail post or the SAB at all, so didn't offer any additional strength to
the area.
Another picture shows a cracked FUS-30. This seems to have been caused by a
loosely held tail spring rocking back and forth with a one sided fork Maule
tailwheel. These Maule tailwheels do cause some extra twisting motion on the
tailspring due to the one sided fork, so try to avoid their usage if you
can. If it's a deal you can't refuse, make sure the Tspring is tight and you
have done the FUS-30 doubler.
Third picture shows the cracked FUS-30 repaired with the suggested FUS-30
doubler to prevent the cracking or buckling, that should be built into EVERY
new fuselage that you guys and gals are putting together.
