CHAPTER 4: EMERGENCY PROCEDURES

GROUND ENGINE FIRE

See Dry Motoring Run in Section II.

ENGINE FIRE IN FLIGHT

1. Power Lever – IDLE POSITION

2. Propeller Lever – FEATHERED

3. Fuel Condition Lever – CUT OFF POSITION

4. Fuel Auxiliary Pump Switch – OFF

5. Fuel Valve – OFF

ENGINE SHUTDOWN IN FLIGHT

1. Propeller Lever – FEATHERED

2. Fuel Condition Lever – CUT OFF POSITION

3. Fuel Auxiliary Pump Switch – OFF

4. Fuel Valve – OFF

5. Power Lever – IDLE POSITION

ENGINE FLAMEOUT

The indications of any engine flameout will be a drop in the inter-turbine temperature, a 

drop

in the torque pressure, and a drop in RPM. The flameout may result from the engine 

running 

out of fuel or possibly caused by an unstable engine operation. Once the fuel supply 

has been restored to the engine or the cause of the unstable operation eliminated, the 

engine may be

restarted in the manner described under Air Starts on the Page III-2.

NORMAL AIR STARTS

NOTE

Air Start Envelope – Normal Air Starts ranging from sea level to 12,000 feet

altitude and above 148-MPH IAS have been approved.

PRE-AIR START CHECK

1. Propeller Lever – ANYWHERE IN THE OPERATING RANGE.

NOTE

Propeller feathering is dependent on circumstances and is at the discretion of the 

pilot. 

Fine pitch selection will pump air through the engine, and; therefore increase the 

gas generator motoring speed during the Air Start procedure.
Report #: ER-511 Title: S2R-T660/-T660DC TRAINING MANUAL

Page: 14 Revision: A Date: 11/25/2013 FAA Project #: N/A

2. Power Lever – IDLE

3. Master Switch – ON

4. Fuel Valve – ON

5. Fuel Condition Lever – CUT OFF

6. Fuel Auxiliary Pump Switch – ON

7. Fuel Pressure Indicator – 5 PSIG minimum

AIR START PROCEDURE

1. Starter Switch – ON, The minimum gas generator RPM to obtain satisfactory ignition

is 13% Ng.

2. Engine Ignition Switch – ON

3. Fuel Condition Lever – GROUND IDLE POSITION after approximately five seconds 

of stabilized gas generator speed.

NOTE

A relight normally should be obtained within 10 Seconds and will be noted first by 

a rise in gas generator RPM. A rise in the inter-turbine temperature will also be 

noted.

The following should be carried out when the engine reaches Idle RPM:

1. Engine Starter and Ignition Switches – OFF

2. Propeller Lever – INTO OPERATING RANGE

3. Power Lever – ADJUST to desire position

4. Fuel Condition Lever – FLIGHT IDLE 

5. CHECK that the Engine Operating Limits are not exceeded. If a satisfactory Start is 

not obtained discontinued the air start. If another starting attempt is to be made, 

repeat the

engine air start procedure.

NOTE

The best air start technique is to initiate the restart procedure immediately after a 

flameout occurs, if the pilot is certain that the flameout was not the result of some 

malfunction which might make the attempt to restart dangerous. There is always 

the chance that the engine may restart successfully just as soon as the ignition is 

turned on. In a flameout situation, move the igniter switch to the on position as 

quickly as possible, if the gas generator speed has not dropped below 58%. 

Under these circumstances it is not necessary to move the fuel lever or feather 

the propeller. However, the power lever should be returned to the idle position. 

ELECTRICAL FIRE IN FLIGHT

1. Battery Switch and Generator Switch – OFF

2. All other Electrical Switches – OFF

3. Circuit Breakers – CHECK to identify faulty circuit, if possible.
Report #: ER-511 Title: S2R-T660/-T660DC TRAINING MANUAL

Page: 15 Revision: A Date: 11/25/2013 FAA Project #: N/A

If electrical power is essential for the flight, try to identify and isolate the faulty circuit by 

doing the following:

1. Generator Switch – ON

2. If the Generator Switch is defective, MOVE the Generator Switch to the OFF position

and then MOVE the Battery Switch to the ON position. Let a short period of time 

elapse

before activating additional circuits one at a time until the defective circuit is 

identified. 

3. Defective Circuit – OFF

EMERGENCY EGRESS

If it is necessary to remove the cockpit door from its hinges, do the following:

1. KNOCK OUT the oval panel below the window.

2. REACH through the hole and PULL UP the flexible hinge pin.

3. PUSH the door clear of the aircraft and EXIT.

FOR DUAL COCKPIT AIRCRAFT:

If it is not desired to release the door from its hinges while exiting the aircraft in the 

normal manner, proceed with the following:

1. The front cockpit door must be closed in order for the rear occupant to exit the 

aircraft.

2. The rear occupant can exit by using the step in the left side of the fuselage below the 

front door.

GENERATOR FAILURE

1. RESET Generator

2. If Generator is not restored, accomplish the following:

a. Air Conditioner OFF

b. All other nonessential electrical equipment OFF

If Generator Fails, Air Conditioner must be turned off to ensure

30 minutes of Battery Power

CHAPTER 6: HANDLING CHARACTERISTICS

The handing characteristics of the S2R-T660 are similar to the handling characteristics 

of other Thrush Aircraft models, and are typical of many other large, turbine-powered

tailwheel aircraft. Obviously, variables such as hopper load, fuel load, loaded c.g., wind, 

runway conditions and construction, and atmospheric conditions will affect the handling 

characteristics of the aircraft. It is suggested that the first few flights be made at lower 

takeoff weights with mid-range loaded c.g., and in relatively calm wind conditions. As 

experience and proficiency allow, takeoff weights may be increased and the c.g. range 

may be expanded to gain well-rounded knowledge of the handling characteristics of the 

aircraft in all flight, loading, and atmospheric conditions.
