EMERGENCY WATER LANDING – POWER ON Make normal approach and landing to water. ROBINSON MODEL R44 II SECTION 9 FIXED FLOATS SUPPLEMENT FAA APPROVED: 17 DEC 2019 9-5.6 ROBINSON MODEL R44 II SECTION 9 FIXED FLOATS SUPPLEMENT FAA APPROVED: 3 OCT 2002 9-5.7 SECTION 4: NORMAL PROCEDURES DAILY OR PREFLIGHT CHECKS 15. Inflatable Floats Float Pressure . . . . . . . . . . Check (See Section 2) Float Condition . . . . . . . . . Check CAUTION Helicopters equipped with inflated floats have an adverse roll characteristic. When sideslipping nose left or right, helicopter will tend to roll in opposite direction and could cause loss of control. To avoid adverse roll, keep helicopter trimmed with zero sideslip. Exercise extreme caution when performing simulated power failures. CAUTION Avoid night flight over water beyond autorotation distance to land. Height above water may be difficult to judge during a water landing. SECTION 4: NORMAL PROCEDURES (cont'd) OPERATION ON WATER CAUTION Except for actual emergencies, maximum weight for water operations is 2400 lb. Safe operation on water has been demonstrated in waves up to 1 foot (0.3 m) (trough to crest). Maximum recommended water taxi speed is 5 knots. Some application of collective is required. Since the helicopter sits very low on water, it is likely that water will leak into the cabin. Water landings should be limited to emergencies and training. For training, seal the removable belly panels and landing gear cross tube cover using aluminum foil tape or duct tape. Avoid salt water if possible. There may be limited tail rotor clearance to water, particularly at aft CG. Also, even small waves may cause enough rocking to dip the tail rotor in the water. If tail rotor contact with water is suspected, have tail rotor inspected prior to further flight. (If no noticeable change in vibration occurs after suspected water contact, helicopter may be repositioned to nearest convenient inspection site.) CAUTION If starting or stopping rotor on water, ensure area is clear as helicopter can rotate one or more complete turns while tail rotor RPM is low.

Autorotations should only be performed to a smooth, hard surface to avoid damage to floats. PRACTICE AUTOROTATION TO WATER Same as practice autorotation with ground contact in basic manual except touch down in slight nose high attitude with nose straight ahead. Maintain cyclic in touchdown position and do not lower collective full down until forward motion has stopped. CAUTION Lowering collective rapidly or applying excessive forward cyclic while helicopter is moving forward on water can cause floats to submerge and helicopter to nose over. CAUTION There may be limited tail rotor clearance to water, particularly at aft CG. Applying excessive aft cyclic may cause tail rotor to contact water.

WEIGHT AND BALANCE RECORD Basic empty weight and CG in float and non-float configurations is included in the Weight and Balance Summary provided with the helicopter. Modifications are to be recorded in the Weight and Balance Record. SECTION 7: SYSTEMS DESCRIPTION The fixed-float landing gear installation includes inflated floats, additional airframe sealing and corrosion protection, additional forward position lights in the mast fairing, longer landing gear struts, and an additional stabilizer installed at the base of the lower vertical stabilizer. Standard landing gear may be installed in place of the float landing gear per maintenance manual instructions. ROBINSON MODEL R44 II SECTION 9 FIXED FLOATS SUPPLEMENT SECTION 8: HANDLING AND MAINTENANCE GROUND HANDLING With floats installed, special ground handling wheels are required. Refer to R44 Maintenance Manual for wheel installation and removal procedures. FLOAT TUBES To promote long float tube life: 1. Do not inflate floats to higher pressure than required by limitations section. Do not arbitrarily inflate floats to relief valve pressure. 2. Reduce pressure in floats if solar heating is causing excessive pressure buildup. 3. Do not allow floats to sit uninflated. Maintain some pressure to keep shape when not in use. CAUTION When inflating chambers individually (without a manifold), increase pressure in each chamber in increments no greater than 0.5 psig. REVISED: 17 DEC 2019 9-5.12 ROBINSON MODEL R44 II SECTION 10: SAFETY TIPS SECTION 9 FIXED FLOATS SUPPLEMENT Flight characteristics and handling qualities with inflated floats are more critical than with conventional landing gear. Helicopters with floats installed have an adverse roll characteristic. When sideslipping nose right or left, the helicopter will tend to roll in the opposite direction out of the turn. This could be extremely dangerous if a pilot failed to apply right pedal or put in the wrong pedal during a simulated power failure. Also, aerodynamic lift produced by floats makes both RPM and pitch control more difficult during autorotation entries. Helicopters with floats installed are also more gust sensitive and difficult to fly in turbulence. For these reasons, it is strongly recommended that floats be removed and standard gear installed for primary flight instruction. With floats installed, pilots must keep the helicopter trimmed with zero sideslip and exercise extreme caution when performing simulated power failures.
