Applicability:
All versions of the engine type Rotax 912 A, 912 F and 912 S all
serial numbers if Fuel pump part no. 892230, 892232, 892540
(standard version) or part no. 892235, 892236, 892545 (version
including flexible fuel line), are installed.
These engines are known to be installed on, but not
limited to, the following aircraft types:
Skyfox CA-25, CA-25N; Diamond (formerly HOAC) HK-36R Super

Reason:
Due to high fuel pressure, caused by
exceeding pressure in front of the mechanical fuel pump (e.g. due
to an electrical fuel pump), in limited cases a deviation in the
fuel supply could occur. This can result in exceeding of the fuel
pressure and might cause engine malfunction and/or massive fuel
leakage.
Non-compliance with these instructions could result in engine
damages, personal injuries or death.
