Q

Ground Resonance NWC

A

Caution
- Application of the rotor brake may aggravate lead lag tendencies and cause a mechanical failure
- Continued operations on deck with unusual vibrations may result in rotor system damage or mechanical failures

Warning
- Ground resonance can occur in under 3 seconds and cause violent vibrations resulting in difficulty reaching the PCLs, PIO, and dynamic rollover
- Failure to ensure that ground personnel are clear of the rotor arc and aircraft is free from the deck or chains may result in loss of aircraft or ground personnel

Q

Loss of TR Control NWC
SMAL Swap 40

A

1) Servo hardovers in the yaw channel may result in loss of tail rotor control. Consider securing SAS/BOOST and/or TRIM
2) A momentary uncommanded right yaw will occur when the tail rotor servo switches
3) With the #1 TR SERVO caution without the BACKUP PUMP or #2 TR SERVO will have normal control above 40kts
4) After touchdown, rapid reduction of PCLs or collective may cause uncontrollable yaw rates
5) If an uncontrolled right yaw develops at too low an airspeed, waveoff capability may be lost. Consider Loss of Drive.
6) If tail rotor cables are damaged, switching from TAIL SERVO norm to backup may cause catastrophic damage to tail rotor controls
