Term
| TR hydraulic slide valve seizure in hover |
|
Definition
if no rotation land normally
if rotation HYD OFF on collective, cancel yaw |
|
|
Term
| TR/MR hydraulic slide valve seizure in cruise |
|
Definition
- collective HYD OFF
- reduce to 40-60 KIAS
- shallow approach, slow running landing
- shutdown |
|
|
Term
|
Definition
let rotor stop before exiting aircraft
aircraft into wind
slight cyclic into wind |

|
Term
| Flight Control hardover/jam |
|
Definition
hardover: uncommanded movements
jam: high control force needed
HIGE, takeoff, final:
- Land immediately
- then hydraulic cutoff
- shutdown
In Flight:
- IAS 40-60 Kts
- hydraulic cutoff
- Land as soon as possible
- shallow approach, running landing |
|

Term
|
Definition
if it doesn't close:
- max engine power is reduced
if it doesn't open:
- engine may surge
- avoid abrupt power changes
GOV amber will illuminate
Land as soon as practicable |

Term
|
Definition
if NR/Nf lower than 375:
- check engine parameters
- check NR/Nf aligned
NR/Nf may be as low as 360
before GOV amber comes on
