Robinson R44 Raven II Model Guide
Robinson R44 Raven II · Model Guide
Overview
The Robinson R44 Raven II is a single-engine piston helicopter with four seats, in production since 2002 per the library record. The supplied sources have no registry maxima and no specs for this model, so this guide does not give range, cruise speed or weight figures. It relies on R44-series flight manual performance pages, airworthiness directives and bulletins, accident investigations and approved modifications. Check anything model-specific against the Raven II flight manual and the aircraft's own records.
- The Robinson R44 Raven II seats 4 and has been built since 2002. Several sources cover the R44 series generally rather than the Raven II specifically.
- Hover performance falls with density altitude, weight and carburetor heat. Full carb heat cuts hover ceilings by up to 2400 ft.
- Check the AD compliance history: tail rotor blade tip caps, engine RPM sensor wiring, the governor controller and the engine/transmission clutch shaft yoke.
- Accident reports cite overweight takeoffs at high density altitude, fuel exhaustion and a seized clutch actuator bearing. A pre-buy should check weight and fuel planning habits and maintenance records.
- Check for external-load or nose-mount modifications (cargo hook or utility mount STCs) and make sure the matching flight manual supplements are present.

How many seats does the Robinson R44 Raven II have?
The Robinson R44 Raven II seats 4, according to the library record. It has been built since 2002.
Does carb heat affect Robinson R44 Raven II hover performance?
The R44 performance section gives hover data with carb heat off and says full carb heat reduces hover ceilings by up to 2400 ft. The section covers the R44 generally, so check the Raven II flight manual for the figures that apply to a specific aircraft.
What should I check about the tail rotor on a Robinson R44 Raven II?
AD 2024-04-02 requires a check of the C029-3 tail rotor blade tip cap area before the first flight of each day (Rev A thru Q), and AD 2022-19-12 requires inspecting C029-3 tail rotor blades (S/Ns 9410-10659) before each flight. On a Robinson R44 Raven II, confirm which part and serial numbers are fitted and that compliance is recorded.

Performance and limits
The R44 Section 5 performance pages state that in-ground-effect hover controllability has been shown in a 17 knot wind from any direction up to 9600 ft density altitude. Hover charts assume carburetor heat off. Full carb heat reduces hover ceilings by up to 2400 ft. Engine cooling has been demonstrated to 38°C (100°F) at sea level, or 23°C above ISA at altitude. The pages warn that the data were obtained under ideal conditions and that real performance can be substantially less. The same section carries airspeed calibration, density altitude, IGE and OGE hover ceiling, and height-velocity charts.
Airworthiness directives to verify
The US AD list for R44-series helicopters includes: 2024-04-02, a check of the C029-3 tail rotor blade tip cap area before the first flight of each day (Rev A thru Q); 2024-20-03, replacing D270-1 Rev A thru E governor controllers with Rev F or later; 2024-19-11, the engine/transmission clutch shaft forward yoke; 2022-12-08, inspecting and modifying the engine RPM sensor wiring; 2022-19-12, inspecting C029-3 tail rotor blades before each flight (S/Ns 9410-10659); 2020-18-08, the R44 II engine air induction hose; and 2023-11-07, restrictions on operations requiring radar altimeters. AD 2024-04-02 notes that helicopters operated near saltwater and stored outdoors are particularly susceptible to tail rotor blade corrosion. Confirm each applicable AD is signed off in the logbooks.
Governor and engine monitoring
Airworthiness Bulletin AWB 67-006 Issue 5 (an advisory, not mandatory) describes reports of the engine RPM governor not controlling RPM, causing overspeed or underspeed. It applies to R44-series helicopters with an Engine Monitoring Unit (EMU). Factory-new helicopters bought after 15 January 2020 had EMUs, and an amber EMU segment on the annunciator panel identifies them. It recommends keeping a light hand on the throttle twist grip, switching the governor off if it is suspected of malfunctioning, and landing as soon as practical. It also recommends removing the C143 engine RPM sensor for cleaning. Ask for the SB-111 and KI-287 compliance status.
Modifications you may encounter
An FAA-approved Airfilm nose utility mount supplement for R44/R44II covers external payloads up to 50 lbs, such as cameras, sensors and searchlights. It is approved for VFR only. VNE is reduced by 10 KIAS for a payload of 0.7 ft2 frontal area or less, and by 30 KIAS for .71 to 1.5 ft2. CASA STC SVR541 covers a dual cargo hook installation for Human External Cargo operations on R44 and R44 II helicopters. It applies to aircraft with a 28V electrical system or a 14V to 28V conversion kit. Confirm that any fitted modification has its supplement and paperwork.

Safety notes
- Weight and density altitude: an R44 Raven I accident (VH-OCL) was likely an overweight takeoff at high density altitude. The pilot used estimated passenger weights and did not recalculate performance for the actual conditions.
- Fuel: a Raven II (VH-IDW) engine stopped from fuel exhaustion. The ATSB found the helicopter was likely not refuelled at the en route fuel depot and that the pilot did not notice the reducing fuel state.
- Maintenance: an R44 (VH-KOV) lost all drive from the engine to the rotor after the clutch actuator lower bearing seized. The bearing had not been maintained in accordance with the maintenance procedures.
- Carburetor ice can form with relative humidity above 50% at -6°C to +32°C, and is most likely at -1°C to +15°C. Know the carb heat procedures and their power cost.
