Chapter 3 - Emergency Procedures Flashcards
LAND IMMEDIATELY
The urgency of landing is paramount. Primary consideration is to assure survival of the occupants. Landing in water, trees or other unsafe areas should be considered only as a last resort.
LAND AS SOON AS POSSIBLE (LAND ASAP)
Land without delay at the nearest adequate site (i.e. open field) at which a safe approach and landing can be made.
LAND AS SOON AS PRACTICABLE
The landing site and duration of flight are at the discretion of the pilot. Extended flight beyond the nearest approved landing area where appropriate assistance can be expected is not recommended.

The second alternative enables the crew to use the affected engine for landing if necessary. Be prepared for engine failure. Monitor N1, TOT, Torque, Oil Pressure, and Temperature of affected engine closely. If the parameters fluctuate or their limits are exceeded perform single engine emergency shutdown immediately.
- LAND AS SOON AS PRACTICABLE
ENG OIL P (system 1) or ENG OIL P (system 2)
Caution Indications

FUEL FILT (system 1) and/or FUEL FILT (system 2)
Caution Indications
One caution indication:
LAND AS SOON AS PRACTICABLE
Caution
Be Prepared For Single Engine Failure.
Both caution indications:
LAND AS SOON AS POSSIBLE
Caution
Be Prepared For Double Engine Failure.
GEN DISCON (system 1) or GEN DISCON (system 2)
Caution Indications
NOTE
Depending on the cause of the GEN DISCON, when switching off both BUSTIE switches the GEN DISCON indication could switch to the opposite side or both generators could come on with Voltage < 28.2 V or > 28.8 V, Current < 0 A or > 200 A. In this case still continue with procedure as stated.
- DC VOLTS, GEN AMPS** – **Check
If one or both parameters: Voltage < 28.2 V or > 28.8 V, Current < 0 A or > 200 A
- Both BUSTIE** **sw’s** – **OFF (both BUSTIE OPN cautions present)
If voltage > 30.5 V:
- Both GEN** **sw’s** – **OFF (both GEN DISCON cautions present)
- Generator failure isolation – Peform, refer to para 3.7.1
If Voltage = 28.5 “ 0.3 V (system supplied by at least one generator)
- GEN sw (affected generator) – OFF
- LAND AS SOON AS PRACTICABLE
If Voltage = 28.5 “ 0.3 V and Current = 0 A - 200 A (system supplied by at least one generator):
- GEN sw (affected generator) – OFF
- LAND AS SOON AS PRACTICABLE
Caution
Since one fuel transfer pump is powered by the shed bus, the amount of unusable fuel increases above that stated in section 2 when problem is identified on SYS1 side, BUSTIE 1 is opened and GEN 1 remains off.
When gen 2 is disconnected and both BUSTIE sw are off, the radalt function is lost which will reduce capabilities of the autopilot, as the auto level off function will be lost.
NOTE
Systems on SHED BUS of affected side will be lost once BUSTIE switches are OFF. Furthermore the other SHED BUS will be lost when both GEN switches are off resulting in various cautions, indicating these systems are failed.
One generator alone will provide sufficient power for continued flight until safe landing can be made.
If winch operation is required for safety of flight, the BUSTIE 1 switch can be momentarily switched to RESET, then NORM, winch operation attempted and when finished the BUSTIE 1 switch must be turned OFF again.
GEN DISCON (system 1) and GEN DISCON (system 2)
Caution Indications
- GEN AMPS** – **Check
If GEN AMPS < 0 A:
- Both BUSTIE** **sw’s** – **OFF (both BUSTIE OPN cautions present)
If both generators remain offline after turning BUS TIE sw’s OFF:
- Generator failure isolation – Peform, refer to para 3.7.1
If one generator comes online again after turning BUS TIE sw’s OFF:
- GEN sw (failed generator) – OFF
- LAND AS SOON AS PRACTICABLE
If GEN AMPS > 0 A:
Note
If GEN AMPS > 0 A this could mean the generator is actually functioning. Still continue procedure as stated.
- Generator failure isolation – Peform, refer to para 3.7.1
Caution
Since one fuel transfer pump is powered by the shed bus, the amount of unusable fuel increases above that stated in section 2 when problem is identified on SYS1 side, BUSTIE 1 is opened and GEN 1 remains off.
When GEN 2 remains disconnected and both BUSTIE sw are off, the RADALT is lost which will reduce capabilities of the autopilot, as the auto level off function will be lost.
Note
The battery will supply the ESS BUS 1 and 2.
Systems on SHED BUS of affected side will be lost once BUSTIE switches are OFF. Furthermore the other SHED BUS will be momentarily lost when both GEN switches are off resulting in various cautions, indicating these systems are failed.
If winch operation is required for safety of flight, the BUSTIE 1 switch can be momentarily switched to RESET, then NORM, winch operation attempted and when finished the BUSTIE 1 switch must be turned OFF again.
Flight endurance depends on battery type and loading
GEN OVHT (system 1) or GEN OVHT (system 2)
Caution Indications
- Affected GEN sw – OFF
Caution
If GEN OVHT Caution Indication Remains on and if there are indications of a fire such as burning odor or smoke, shut down the affected engine.
If GEN OVHT caution indication remains on for more than 1 minute:
- OEI flight condition** – **Establish
- Affected engine** – **Identify
- Single engine emergency shutdown** – **Perform
- LAND AS SOON AS PRACTICABLE
