All Kitfox™ owners with 582LC Engines
Denney Aerocraft Company
has advised us that in their “duration” testing, the thread-bosses
in three locations on the crankcase where the gearbox attaches failed.
Engines concerned: All 582’s and a limited number of late 532’s Rotax Engines
and late 532’s with serial numbers 3799005 through 3799500 are
limited to a maximum of 20 operating hours and must not be operated
beyond that limit until remedy has been implemented. Failure to heed
this mandatory limitation could result in in-flight catastrophic failure
with resulting loss of limb or life.
5-6 weeks, Rotax will make available a new gearbox housing and screws to
all 582LC Engine owners. This new gearbox housing will be attached to
the crankcase by two additional screws. Instructions will come with the
