IMPORT REQUIREMENTS To be considered eligible for installation on United Sates registered aircraft, each new
engine to be exported to the United States with ACG or EASA airworthiness approval shall
have a Joint Airworthiness Authority (JAA) or EASA Form 1, Authorized Release
Certificate. The JAA or EASA Form 1 should state that the engine conforms to the type
design approved under the U.S. Type Certificate E00058NE, is in a condition for safe
operation and has under gone a final operational check.
NOTES
NOTE 1. Temperature Limits (maximum permissible):
Cylinder head: 135oC
Coolant: 120oC (for engine type designation extended with suffix -01)
Oil inlet: 130oC
NOTE 2. Pressure Limits:
Fuel Pressure at inlet to Carburetor: 0.15 bar (2.2 psi) - minimum
0.35 bar (5.0 psi) - maximum
The fuel pressure must not exceed 0.35 bar (5.0 psi) to ensure not to
override the float valve in the carburetor.

electric starter, engine mount, turbosupercharger and turbocharger control unit,
muffler, fuel pumps and alternator, but without the radiator.
914F3: 77.4 kg (170.6 lbs), with propeller flange P.C.D. 75/80 mm / 4”, drive and
adapter for hydraulic governor for constant speed propeller, governor and
alternator.
Alternator (external): 3.0 kg (6.61 lbs).
Center of Gravity (CG): Reference the 914F Installation Manual, latest revision
(see NOTE 7).
NOTE 5. Fuel Specifications (see Operator’s Manual as defined in NOTE 7):
• 100LL AVGAS in accordance with American Society for Testing & Materials (ASTM) D910.
• Automotive gasoline, unleaded regular, minimum RON 95, in accordance with ASTM D4814.
NOTE 6. Model Description:
F2 Basic model; 4-stroke, 4 cylinder horizontally opposed, turbosupercharger and
electronic turbosupercharger control unit, one central camshaft, push-rods,
overhead valves, liquid cooled cylinder heads, ram air-cooled cylinders, dry
sump forced lubrication, dual breakerless capacitive discharge ignition, two
constant depression carburetors, two electrical fuel pumps, fixed pitch propeller
configuration, drive output via reduction gear with integrated shock absorber and
overload protection, electric starter, integrated DC generator, steel exhaust
system, vacuum pump drive (optional), and external alternator (optional).
F3 Same as F2, except; additional drive and adapter for hydraulic governor propeller
shaft for constant speed propeller with governor installed.
F4 Same as F3, except; fixed pitch propeller, prepared for installation of hydraulic
governor for constant speed propeller (without drive, adapter and governor).
914 F2/3/4 engine Same as described above, except; engine temperature measurement methods have been
type designation amended from CHT (cylinder head temperature) and CT (coolant temperature) to only CT
extended with (coolant temperature). Therefore only the coolant temperature limit applies. For further
suffix -01 details refer to Service Bulletins SB-914-047 and SB-914-049 (respectively latest revision).
NOTE 7. Operating and Service Instructions:
• Operator’s Manual for Rotax 914F Aircraft Engine - Part Number OM-914 (all models)
• Installation Manual for Rotax 914F Aircraft Engine - Part Number IM-914 (all models)
• Maintenance Manual Line for Rotax 914F Aircraft Engine - Part Number MML-914 (all models)
• Maintenance Manual Heavy for Rotax 914F Aircraft Engine - Part Number MMH-914 (all models)
• Overhaul Manual for Rotax 914F Aircraft Engine - Part Number OHM-914 (all models)
• Overhaul Manual Appendix for Rotax 914F Aircraft Engine - Part Number OHMA-914 (all models)
NOTE 8. Generator and Alternator Operation:
The optional external alternator was certified with the engine under 14-CFR, part 33, using some of the standards
specified in Aerospace Standard AS 8020. Compliance to the AS 8020 standard for parallel operation of the
optional external alternator and integrated internal generator has been demonstrated.
NOTE 9. Vacuum Pump:
During 14-CFR, part 33 certification of the 914 F series engine, compliance for the vacuum pump has only been
shown to the attachment requirements of 14-CFR, part 33.25.
TCDS E00058NE PAGE 5
NOTE 10. Governor:
During 14-CFR, part 33 certification of the 914 F series engine, compliance for the Woodward hydraulic governor
has been shown to the attachment requirements of 14-CFR, part 33.25, and in lieu of 14-CFR, part 35.42 (as
required by part 33.19(b)), JAR-E (b)(1)(ii) was used for governor functional testing.
NOTE 11. Engine Attitude:
The 914 F2/F3/F4 model engines have been certified up to a maximum 40 degree bank angle, with no loss of
lubrication capability of the dry sump system. See Rotax 914 F Operator's Manual, section 7, titled, Operating
Instructions.
NOTE 12. Critical Altitude:
Five minute takeoff power is limited to a critical altitude of 8000 feet (2450 meters).
NOTE 13. Takeoff Power:
Five minute takeoff rated horsepower is 84.5 kW/115 HP when the single channel digital turbocharger control unit
(TCU) is operable. Available takeoff power is limited to 66.1 kW/90 HP if the TCU fails prior to or during
takeoff roll, unless the waste gate lockout switch is engaged and manifold pressure is assured just prior to takeoff
roll. Therefore, aircraft installation that require more than 66.1 kW/90 HP for safe takeoff must have
procedures requiring waste gate lockout engagement prior to every takeoff.
NOTE 14. Overhaul:
The Rotax 914F series engine must be overhauled in accordance with the approved overhaul manual.
NOTE 15.
NOTE 16.
Engine Certification:
