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 Dimona, DV 20 Katana; Aeromot AMT-200 Super Ximango; Diamond DA20-A1 Katana; Evektor-Aerotechnik EV-97 Eurostar; Issoire APM-20 Lionceau; EIS (Fournier) RF-9; Scheibe SF 36R, SF 25C; Technoflug TFK-2 Carat; WD D4 BK Fascination; III Sky Arrow 650 TC, 650 TCN and 650 TCNS; ABS RF-9 motor glider (Fournier design);

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.
