Loss of tail rotor components |
a. The severity of this situation is dependent upon the amount of weight lost. Any loss of this nature will result in a forward center of gravity shift, requiring aft cyclic. A full autorotational descent and landing should be accomplished with a run-on type termination if to an improved surface, or minimum ground run if to an unimproved surface. Landing should be accomplished in a level attitude. b. Indications: 1. Varying degrees of right yaw depending on power applied and airspeed at the time of failure. 2. Forward CG shift. C. Procedures: 1. Enter autorotative descent (THROTTLE CLOSED). 2. Maintain airspeed above minimum rate of descent airspeed. 3. If run-on landing is possible, complete autorotation with touchdown airspeed as required for directional control. 4. If run-on landing is not possible, start to decelerate from about 75 feet altitude, so that forward groundspeed is at a minimum when the helicopter reaches 10 to 20 feet; execute the touchdown with a rapid collective pull just prior to touchdown in a level attitude with minimum ground run. |

Vfr generator failure- no output |
a. A no-output malfunction of the generator will be indicated by a zero indication on the DC Load Meter and an illumination of the MAIN GEN FAIL caution light. An attempt may be made to put the generator back on line by accomplishing the following:
1. GEN FIELD, and GEN RESET Circuit Breakers ─ Check In.
2. MAIN GEN switch ─ Reset then MAIN GEN. (Do not hold the switch in the RESET position.)
b. If the generator is not restored, or if it goes off line again:
1. MAIN GEN switch ─ Off.
2. Turn OFF all unnecessary electrical equipment.
3. Land as soon as practicable. |

hydraulic power failure |
a. The first indication of hydraulic boost failure will be an increase in the force required for control movement; feedback forces will be noticed as well as rate limiting. Control motions will result in normal flight reactions in all respects, except for the increase in force required for control movement. In the event of hydraulic power failure, proceed as follows:
1. Airspeed ─ Adjust as necessary to attain the most comfortable level of control movements. 2. HYD BOOST circuit breaker ─ Out. Check for restoration of hydraulic power.
B. If hydraulic power is not restored.
1. HYD BOOST circuit breaker ─ In.
Do not return the HYDR SYSTEM switch to the ON position for the remainder of the flight. This prevents any possibility of a surge in hydraulic pressure and the resulting loss of control. 2. HYDR SYSTEM switch ─ OFF.
3. Land as soon as practicable at an area that will permit a run-on landing.
