NTS Stuck NTS Plunger or stuck power lever actions abs over speed during NTS check
1: Clean up NSWE
2: Speed up
3: have FE try to adjust lever
4: if still binds, pull E handle
5: if E handle binds, use the feather button abs perform emergency shutdown checklist
Propeller fails to feather during loiter shutdown checklist
1: perform first 4 items of prop fails to feather checklist
- if it feathers: complete rest of loiter shutdown Checklist
- if not: complete rest of prop fails to feather checklist followed by the emergency shutdown checklist
Execute Emergency Shutdown procedure when…
E: Extreme or abnormal engine vibration
E: Excessive or uncontrollable power loss
S: sudden or uncontrollable rise in oil temperature
G: Gear case or engine oil pressure becomes low or excessive
T: TIT Increases and cannot be controlled
W: When a magnetic chip detector light illuminate study or intermittent acompanied by secondary indications
A: Actuation of the fire warning system (study or intermittent)
When to shut down an engine
V: excessive vibration P: Power Loss F: Fire O: Oil temp O: Oil px T: excessive TIT C: chip light with secondaries
APU In-flight start procedures
G: APU Generator switch off F: Fuel booster pump on A: In-flight arm switch armed S: APU start switch start, release to on G: After APU rpm has stabilized, turn the APU generator switch on
Use of APU in Flight with MAIN DC BUS failed and MEDC BUS powered…
1: shift controls to Boost Off and pill three phase power cb for TR 3 before placing APU control switch to ON or START allowing Flight Essential Bus starter relay to close when Sequenced by the APU start control system
2: If the steps are not followed in the sequence given the APU will not start, in which case the APU control switch must be placed two off then back to start
If Emp deice needed during partial load monitoring, turn on…
5 pumps abs a fan: 3 boost pumps and 2 Hyd pumps and cabin exhaust fan
Stuck NTS Plunger indications and action
Indications
- decrease in rpm dropping off quickly (if plunger fails to retract holding the fx valve towards increase blade angle)
- SHP going positive
Action
- pull e handle
(If not it could chase TIT to rise rapidly due to the FCU)
JA 11-29
Stuck power lever during NTS
1: clean up from check
2: speed up
3: if it still binds, ehandle
4: if e-handle binds, feather button
Over speed during NTS check
Same as stuck power lever
How to access GOB (usually after securing Ess bus switch on an FOUO)
(GAG)
G: GOB relay cb
A: APU in flight arming switch to Arm
G: gear down (nose gear)
S: SEAC and SEDC select an engine or put inverter test switch to test
Flying the ditch flow
1: Alert crew time to impact, carry out ditching checklist
2: 300’ above water set 160kts (1.35 speed) at approach flaps and establish ditch heading
3: don gloves and helmet (both pilots)
4: select land flaps and slow to 1.3 speed and defend at 100fpm (direct CP to call every 100ft and then every 10ft)
5: CP will update crew with impact time and P removes hands from power levers prior to impact
How to get TIT instrument through the battery?
Engine start selector switch powers emergency inverter
How can you activate load monitoring if GEN 4 AUX CONT is tripped?
Use the prop or emp deice systems
What are monitored when prop deice or emp deice is activated during single Gen auto load monitoring? (Happens auto without turning on prop deice or emp at 8kft)
(Feeders, heaters and eaters)
Feeders: BUS A and Main DC feeders
Heaters: side windshield heat and floor/wall heaters
Eaters: galley power
Additional loads: emp deice and No1A hyd pump
When do go boost out, when to not
Boost out if: abnormally high force is required or you can’t stop uncontrollable nose up or down, rolling or yawing
Don’t if: T: it’s trim A: if it’s AP malfunction B: binding F: controls move freely
If you can’t: shift other two systems, turn off AC hyd pumps, shift bad system out (if it works, put the other two systems back to boost off). If it doesn’t work, leave hyds off for flight and ref procedure)
Speed sense control malfunction don’ts (ANRR)
A: don’t use autofx
N: TD switch to Null and pull fuel shutoff valve cb
R: don’t shutdown with intent to restart
R: reset cb prior to securing engine with fuel and ignition switch
Equivalent loads for load monitoring (5 pumps and a fan)
Pumps: hyds 1 and 2, 3 bp’s
Fan: cabin exhaust fan
Speed sense control malfunction criteria
A: don’t use autofx
F: pull fuel shutoff valve cb and place TD switch to NULL
I: don’t shut down that engine with intent to restart
R: reset cb prior to securing Engine with fuel and ignition switch
Considerations before securing an engine for a fire with prop fails to feather
F: confirmed dire indications and effect of HRD
I: indications of fire source (oil or fuel leak)
R: indicated rpm
D: distance to suitable landing field
During single gen ops, Operation of either empennage or prop deice automatically disconnects…
Feeders: Bus A and B
Eaters: galley power
Heaters: side windshield heat, floor and wall heaters
(Or further reduced by securing lighting and other nonessential equipment)
Single gen preparation
B: boost handles uncovered U: utility light positioned F: flashlights close by B: cp briefed to place ESS BUS switch off V: fly VMC
Don’t move power levers into Beta until less than 125kts with no gens operation because
This eliminates the possibility of inadvertent pitch lock caused by depleted battery power
If APU start attempted with MAIN DC and MEDC Buses failed
B: shift boost off
P: pull TR3 cb
Before turning the APU control switch to ON or START
(Allows FEDC starter relay to close when sequence by the APU start control system)
If it you don’t do this, reset and try again
(15-3)
Additional load monitoring drops
Empennage deice and No. 1A hyd pump
Equivalent loads to the emp deice manually monitored
No. 1 & 2 hyd pumps
3 boost pumps
Cabin exhaust fan
If prop rotates backwards
1: push in E-handle
2: pull fx button to UNFX
3: when rotation stops: FX neutral
4: pull prop fx control cb
5: pull e-handle back out
Starting APU in flight
G F A S T G
When to shift boost out
1: controls seem immovable or require abnormally high force
2: aircraft pitches up or down, rolls or yaws and application of pilot force on controls is ineffective
When to not shift boost off
T: if a trim system problem occurs
A: if an autopilot malfunction occurs
B: binding of a control cable
C: control of elevator, rudder or aileron is lost
