1.7. Single-engine Mentality. The T-6 engine has an excellent record of reliability, but the potential for engine loss deserves special consideration. Following an engine failure, if the engine can’t or shouldn’t be restarted, two options exist: recovery to a suitable airfield or ejection. Following a successful restart, stay on profile for an emergency airfield. Emergency landing pattern (ELP) practice increases the chances of successful recovery; however, the aircraft is fitted with a highly capable and proven ejection seat that should be used if there is any doubt about safe recovery. Special single-engine considerations include:

1.7.1. Maintain extra vigilance and a conservative response to unusual engine indications. With unusual engine indications, recover to a suitable airfield.

p. 16

1.7.2. Maintain awareness of nearest suitable emergency airfields during all phases of flight.

1.7.3. Do not shut down the engine in flight if it is producing usable thrust unless it is confirmed to be on fire, is vibrating excessively with indications of impending failure, or as directed by the T.O. 1T-6A-1.

p. 16

1.7.4. Set a minimum ejection altitude when immediate ejection is not warranted. This altitude is based on energy level (altitude and airspeed), configuration, and position relative to a suitable emergency airfield.

p. 16

1.7.5. Determine if an engine restart should be attempted. Consider the time delay and altitude lost between restart initiation and usable torque, the risk of fire, the presence of FOD, and decide if the engine is seized or not. (Often referred to as “fire, FOD, or frozen”.)
