33
B2 Engine failure EP
- set low collective pitch - monitor and control rpm - establish airspeed ~65kts - fuel flow control to shutdown - depending on cause of failure - re-light engine - otherwise: close fuel shutoff, boost pumps off, generator, alternator, electrical master off if burning smell
34
B2 re-light procedure
- Boost pumps on - generator on - NG bellow 30%, normal start procedure.
35
B2 Governor failure - low side
- Establish auto at ~65kts - advance fuel into emergency sector - establish 70% NG - increase collective to 350rpm if necessary - increase fuel until rpm 380rpm
36
B2 Governor failure - high side
- NG, T4, NR increase - do not reduce collective - reduce fuel until rotor speed is center of green arc - continue flight ( any adjustment to collective will need a fuel flow adjustment)
37
B2 Engine fire during start
- Close fuel shut off, rotor brake if needed - booster pumps off - crank for 10 seconds then battery off - use nearby extinguisher to fight fire
38
B2 Fire in flight
- enter auto - close fuel shut off - booster pumps, generator, alternator off - electrical master off if smell of burning
39
Smoke in cabin
- Heater off - Electrical master off - after smoke has cleared set all switches off - reset battery to on - reset master - generator on check voltage - circuits on one by one until malfunction is identified
40
B2 Tail rotor control failure
- 70kts level flight - press hyd test to depressurize yaw load compensator, rest after 5 sec - make a shallow approach with a left side slip - perform run on landing (side slip will reduce as power is applied)
41
B2 Low oil pressure
- test warning light panel ENG P - light does not illuminate - if torque is too low: enter autorotation - if torque is correct: land ASAP - light does illuminate - if torque is too low: land ASAP - if torque is correct: land as soon as practical, monitor eng. P. Light
42
B2 NG indicator failure
- do not exceed torque - keep T4 bellow: - bellow 15° 730° - above 15° 750°
43
Torque meter failure
- Do not allow NG to rise above chart limits
44
B2 T4 failure
-comply with NG limits - do not start
45
Hyd light
- set a/s 40-60kts - collective hyd switch off - shallow approach to no hover landing or around 10kts
46
MGB. P. Warning light
- Reduce power - Land ASAP
47
MGB. T. Warning light
-Test advisory panel for MGB. P. - light does not illuminate, follow MGB. P. EP - light does come on, land and check oil, if oil is normal fly to nearest base.
48
Bat. T. Warning light
- isolate battery - land ASAP
49
B2 ENG. P. Light
- Reduce power - Check pressure indicator: - if pressure is low, read torque meter - torque low, shut down engine - torque normal, land immediately. - if pressure and torque are correct, land as soon as possible.
50
Gen. Light
- test voltage - check push button - attempt reset - shed least essential - land as soon as practical
51
Batt. Light
- check push button - keep watch of voltage - continue flight, according to circumstances
52
Fuel light
- fuel less than 15.8 gallons(18 min) - avoid large attitude changes
53
Door light
- reduce speed 120kts -Land if possible or continue flight at lower speed
54
ENG. chip
- land as soon as possible
55
F Filt.
- reduce power - if light goes out continue flight at reduced power - if light remains on land asap
56
CHIP. TGB
- Continue flight, avoid prolonged hovering
57
CHIP. MGB
- reduce power - Monitor MGB. P, MGB. T. Light - if either light comes on follow appropriate EP
58
B2 FUEL P. Light
- check fuel pressure - if pressure normal, one pump is faulty: continue flight - if pressure zero, both pumps are faulty: continue flight bellow 5000’
59
B3 engine failure
- Establish auto ~65kts - flight selector to off - according to cause: - relight engine - Otherwise: - fuel shut off: off - generator, alternator, electrical master off(if smell of burning)
60
B3 re-light procedure
- Boost pump: on - NG bellow 5% - Gov warning lights out - normal start - boost pump off
61
B3 engine fire on start
- fuel shut off: off - booster pumps: off - crank for 10s - use extinguisher to fight fire
62
B3 engine fire in flight
- enter auto - fuel shut off valve: off - Gen/alt: off - electrical master off if smell of burning
63
B3 low oil pressure
- test advisory panel ENG P - Light does not come on - shut down engine and auto - Light does come on - land ASAP
64
B3 VEMD screen failure
- select failed screen off
65
B3 VEMD double display failure
- Select power setting required for level flight - land without hovering
66
B3 NG indicator failure
- Maintain torque within limits - do not exceed 810° T4
67
B3 Torquemeter failure
-Do not allow NG to exceed NG % on chart
68
B3 T4 indicator failure
- comply with NG limits - turn off heating - do not attempt to start
69
B3 gov failure
- check flight parameters - keep NR in green - unlock flight detent (twist grip) - fly approach at 40kts, allow NR to droop to settle to ground upon reaching a hover
70
B3 ENG. P light
- Reduce power - check oil pressure indicator: - if pressure low, shut down and perform autorotation - if pressure correct, land ASAP
71
B3 gov light (amber)
- governing function degraded - avoid abrupt power changes
72
B3 fuel P light
- reduce power - boost pump on - land ASAP
73
When is the dog bone flexible and rigid?
- Flexible in shear - Rigid in compression
74
Vne and max alt for floats
- max altitude - 6,600’ agl - max inflation speed - 75kts - max speed inflated - 95kts
