lished on the basis of the engine type ROTAX 914 F2-01 as detailed in the ROTAX Mainte-
nance Manual, Line Maintenance: ROTAX MML-914, Edition 2, Revision 2, dated February 1,

3.
STEMME does NOT approve operating beyond the stated engine TBO (dened by ROTAX
and applied by STEMME) for its engine ROTAX 914 F2/S1. Any decision to operate beyond
the recommended TBO for the engine ROTAX 914 F2/S1 based on the informed recommen-
dation of competent, ROTAX–qualied, authorized maintenance personnel is without the
recommendation of STEMME and as such STEMME does not assume the resultant risk.
4.
STEMME builds the ROTAX 914 F2/S1 engine by modifying the certied ROTAX 914 F2-01 which
is its major component. STEMME certied the ROTAX 914 F2/S1 engine and its variable pitch
propeller as part of the S12 under EASA type certicate EASA.A.054. Only STEMME–approved
data is applicable for overhaul and inspection of STEMME’s ROTAX 914 F2/S1 engine.
5. STEMME strongly recommends that you not exceed the recommended TBOs as specied in
the table. In any case, components must be replaced “on condition” if inspection indicates
a need to do so or as required by mode of operation.
6. Seat belts must be inspected and, if needed, be repaired or replaced pursuant according
to applicable national regulations or product limitations.
7.
The L’Hotellier connections wear by use, which may critically impair airworthi-
ness. STEMME recommends to owners and operators to inspect these connec-
tors per L’Hotellier Instructions for the Maintenance L’Hotellier Ball and Swiv-
el Joints, Ref. IMA10.01, in the latest approved revision. This technical data can be
provided by L’Hotellier S.A., 93 Avenue Charles De Gaulle, 92270 Bois Colombes, France.
See Annex A, for L’Hotellier’s specied inspection procedure and tolerances.
