GENERAL The procedures contained in this section are to be followed in the event of an emergen- cy or malfunction that may potentially affect the safety of the aircrew, passengers, aircraft, or personnel on the ground.
Page 72 CSP−900RFM206A−1 ROTORCRAFT FLIGHT MANUAL MD900 with PW 206A Emergency and Malfunction Procedures Audio warnings alert the pilot through the headset that a malfunction has occurred that may require immediate corrective action. The warning tone: The warning tone will sequence a high and low tone twice to indicate a warning condition.
Page 73 CSP−900RFM206A−1 ROTORCRAFT FLIGHT MANUAL MD900 with PW 206A Emergency and Malfunction Procedures Conditions: In flight: Maintain operating engine within OEI limits Reduce airspeed to 100 kts or less (Ref. Section II) Identify affected (failed) engine by cross checking torque, N CAUTION prior to performing following steps.
Page 74 CSP−900RFM206A−1 ROTORCRAFT FLIGHT MANUAL MD900 with PW 206A Emergency and Malfunction Procedures SECOND ENGINE FAILURE Indications: Low rotor RPM with low rotor tone ON if RPM is below 88%. Possible left yaw Torque, N , and N decreasing to zero. Procedures: Lower collective and maintain rotor speed within limits Perform autorotation to suitable landing area.
Page 75 CSP−900RFM206A−1 ROTORCRAFT FLIGHT MANUAL MD900 with PW 206A Emergency and Malfunction Procedures 3−4. EMERGENCY LANDING PROCEDURES WATER LANDING − DUAL ENGINE FAILURE Procedures: Adjust collective pitch as necessary to establish autorotation. Cabin doors may be opened when airspeed is 60 KIAS or less. Make autorotative approach, flaring as required to minimize forward speed at touchdown.
Page 76 CSP−900RFM206A−1 ROTORCRAFT FLIGHT MANUAL MD900 with PW 206A Emergency and Malfunction Procedures Fly a safe distance away from all personnel in the water to avoid injury. Place ENGINE CONTROL switch(s) in OFF and perform a hovering autorota- tion. Allow aircraft to settle in a level attitude while applying full collective pitch. When aircraft begins to roll, reduce collective to full down to minimize blades skipping off the water.

FLIGHT CONTROL MALFUNCTIONS ANTI−TORQUE FAILURE − GENERAL Different types of failure require different techniques for optimum success in recovery. It is not possible to identify all failure scenarios. However, under- standing the following general guidelines will assist the pilot in controlling the aircraft.
Page 89 CSP−900RFM206A−1 ROTORCRAFT FLIGHT MANUAL MD900 with PW 206A Emergency and Malfunction Procedures Wind speed and direction at the landing site can be beneficial if optimized for the particular type of anti−torque malfunction. Head winds reduce ground speed and/or power required at touchdown. Left crosswind components can help weathervane the aircraft against the yaw tendency caused by the particu- lar malfunction.

Do not exceed these limitations at any time during flight. Use the helicopter Basic Weight as recorded in the Basic Weight and Balance Record inserted in this section to perform all weight and balance computations.
Page 196 CSP−900RFM206A−1 ROTORCRAFT FLIGHT MANUAL MD900 with PW 206A Weight and Balance Data 6−4. LONGITUDINAL WEIGHT AND BALANCE DETERMINATION: PASSENGER CONFIGURATION Determine that the gross weight and longitudinal center of gravity (fore and aft) for a given flight are within limits. Proceed as follows. Obtain aircraft basic weight and moment from the Weight and Balance Record in- serted in this section.
Page 197 CSP−900RFM206A−1 ROTORCRAFT FLIGHT MANUAL MD900 with PW 206A Weight and Balance Data 6−5. LONGITUDINAL LOADING OF CARGO The large aft compartment of the Model 900 provides great flexibility in the variety of cargo loads it can accommodate. To determine the gross weight and center of gravity for a given flight are within limits, proceed as follows.
Page 198 CSP−900RFM206A−1 ROTORCRAFT FLIGHT MANUAL MD900 with PW 206A Weight and Balance Data 6−6. PERMISSIBLE LATERAL LOADINGS − PASSENGER CONFIGURATION Safe operation of this helicopter requires that it be flown within established lateral as well as longitudinal center of gravity limits. It is therefore imperative that lateral center of gravity control be exercised.
Page 199 CSP−900RFM206A−1 ROTORCRAFT FLIGHT MANUAL MD900 with PW 206A Weight and Balance Data 6−7.
