B206 Emergencys

Question 1

Warning lights

Engine out

Answer 1

N1<55%
If N2 dropping, engine has failed- lower collective & enter autorotation
False Eng out indication will happen if N1 gauge fails. Flight characteristics will be unchanged. Land as soon as practical.

Question 2

Caution lights

A/F fuel filter

Answer 2

Airframe fuel filter clogged- Land as soon as practical,clean before next flight

Question 3

Baggage door

Answer 3

Baggage door not securely latched, land as soon as practical

Question 4

Engine Chip

Answer 4

Metallic particles in engine oil. Land as soon as possible

Question 5

Engine relight

Answer 5

Engine igniter is operating

Question 6

Fuel filter

Answer 6

Engine fuel filter clogged- Land as soon as practical, clean before next flight

Question 7

Fuel pump

Answer 7

One or both fuel boost pump failed, descend below 6000ft unusable fuel is 10gal. Land as soon as practical

Question 8

Gen Fail

Answer 8

Generator off line
If Gen switch is off-switch on
If Gen switch is on& Gen fail is on- reset once then on.
If Gen fail stays goes out- continue flight.
If Gen fail stays on- switch off, unnecessary electronic off. Land as soon as practical.

Question 9

IBF Filter

Answer 9

AFB inlet barrier clogging- reduce power if possible, monitor TOT & N1
If IBF Filter stays on or TOT rises or performance unacceptable- select IBF bypass switch to open, exit dusty conditions.
Service before next flight.

Question 10

Rotor low rpm

Answer 10

Rotor Rpm below 90%- reduce collective & ensure Throttle is full open.

Question 11

T/R chip

Answer 11

Metallic particles in tail rotor gearbox oil.

Land as soon as possible

Question 12

Trans chip

Answer 12

Metallic particles in transmission oil.

Land as soon as possible.

Question 13

Trans oil press

Answer 13

XMSN oil pressure below minimum

Land as soon as possible

Question 14

Trans oil temp

Answer 14

XMSN oil temperature above red line on gauge.

Land as soon as possible

Question 15

Compressor stall/surging

Answer 15

ToT increase, torque decrease,erratic N1 or N2, reduce collective, anti-ice on, heater on.
If stall/surge severe. Enter auto rotation, shut down engine.
If less severe, maintain power below, below stall/surge point, land as soon as practical.

Question 16

Engine driveshaft failure

Answer 16

Left yaw, N2/NR needle split, rapid NR decrease, rapid N2 increase, ROTOR LOW RPM, and audio tone.
Immediately enter autorotation , keep throttle open.

Question 17

Engine oil pressure low, high or fluctuating

Answer 17

Pressure above red line or below lower red line.
Land as soon as possible

Question 18

Engine oil temperature above red line

Answer 18

Land as soon as practical

Question 19

Engine over speed/ under speed

Answer 19

Noticable decrease or increase in NR, N2, N1 & torque
N2 low, lower collective, confirm throttle full open, maintain flight
If can’t maintain- enter autorotation & keep throttle open.
If N2 high- control with throttle and collective & maintain flight.
If over speed uncomfortable, enter autorotation, shut down engine.

Question 20

Hydraulic failure
Noise from pump, control forces increase+ feedback on cyclic & collective or uncommanded movements

Answer 20

If uncommanded control movements hydraulics off, airspeed 70-80 mph, land as soon as possible.
Control force increase+ feedback, 70-80mph, ensure switch is on. If ON pull yellow hyd. circuit breaker. If return to normal land as soon as practical.
If no change, hyd breaker in switch off land as soon as practical.
