Section 3051                                 ENGINE FAILURES

B. FUEL PRESSURE FAILURE DURING TAKE-OFF (CONT'D)

GR-1820G-102

2. (Cont'd) low fuel pressure) and the carburetor or between the crossfeed valve and the carburetor has broken and gasoline is flowing out into the open. The proper procedure is to immediately go on single engine operation using the engine with the normal fuel pressures. In order to prevent fire, promptly turn tank selector (for engine with low pressure) "Off".
Caution: Do not turn crossfeed "on" at low altitudes because of possibility of losing the good engine. Do no turn crossfeed "on" unless tank selector for engine with low fuel pressure is in off position, otherwise relief valve failure or broken line may cause loss of both engines. If flight is at an altitude sufficient to risk momentary loss of power on the good engine, try turning the crossfeed "on". If in this case, the low fuel pressure comes back up the break is between the tank selector and the engine driven pump. It is perfectly all right to continue operation of both engines from the pump of the good engine. Turn tank selector "off" to prevent loss of fuel.

for failing engine to anther tank. This will not affect the operation of the good engine. If this fails to bring pressure back to normal, there is a broken line between the tank selector and the carburetor. It will be necessary to go on single engine operation using the engine with normal fuel pressure. In order to prevent fire, promptly turn tank selector (for engine with low pressure) "off".

3. (GR-1820G-102 only) If fuel pressure comes entirely back up to normal upon operation of the wobble pump, the engine with the low fuel pressure has had a fuel pump or relief valve failure. In this case turn crossfeed "on". The good pump on the other engine will feed both engines. 

C. FEATHERING PROCEDURE 

1. In the event of engine failure in flight when the Captain gives the command for feathering the propeller, he shall close the throttle for the engine to be stopped, and at the same time, adjust the propeller and throttle controls on the live engine to:

2100 RPM and 35" Boost

2550 RPM and 35" Boost

2. At the Captain's command to feather, the First Officer shall: 

Rotate the "Red Feathering Valve" for that engine approximately two turns open. 

Depress the "Red Feathering Button" for the engine to be feathered. 

3. After operating the feathering control the First Officer shall move the mixture control for the feathered engine to "Cut-Off", and the mixture control for the good engine to:

"Full Rich" on G-102 engines 

"Auto Rich" on 1830-92 engines
