B-912-056: MANDATORY REPLACEMENT OF ROTAX PROPELLER GEARBOX, ENGINES
TYPE 912/914

Compliance
- during the next maintenance event
- at the latest April 30th 2008.

Reason
Due to a slightly increased amount of irregularity in the form of
material inclusions some isolated problems were detected on the
gearbox and/or the gear set in the field.

Such material inclusions in the area of the tooth base can lead to a
tooth break under severe operating conditions.

Normally broken metal fragments are dropping to the lower portion of
the gearbox and are retained captive by the magnetic plug, but in
individual cases they may get squeezed by rotating gear sets further
damaging the gearbox housing.
