FTR Technical Bulletin No. FTR-014
It has come to our attention that on some EGT gear-
boxes the reverse idler screw (SCR-117) has come
loose, even though having been loctited on assembly.
This is the same screw and reverse idler design used in
the FTR. It is to be noted that no incidents of this screw
coming loose on the FTR has been reported to
Hewland. To avoid the possibility of it coming loose we
have modified the screw to include four holes to facili-
tate the use of lockwire and have also modified the
maincase FTR-201 as well with a hole to pass it
through.
We recommend that this modification be done to all
gearboxes that you have. Below are the details of the
modifications.
