Step 7. Engine Stop - Lycoming TEO-540-A1A Installation And Operation Manual

TEO-540-A1A Engine Installation and Operation Manual
NOTICE: Ground operation of the engine is not an acceptable substitute for an in-flight test.
Ground operation does not supply sufficient cooling for the cylinders and can cause
contamination in the Lubrication System (with water and acid) which can cause
substantial damage over time to cylinders and other engine components such as
camshafts and lifters.
Do not turn the propeller by hand as a short cut to lubricate the engine since this
manual rotation removes residual oil.
11. Monitor the oil temperature, CHT, EGT, and the climb angles. Keep the airframe speed at a
sufficient air speed to keep the CHT within the specified range in Appendix A.
NOTICE: During engine operation, the data logger (if installed) will automatically record all
engine operating data. This data can be accessed after flight on the FST.
12. After 10 hours of engine operation for a new, overhauled, or rebuilt engine, complete the 10-
hour inspection. Refer to the TEO-540-A1A Engine Maintenance Manual.

Step 7. Engine Stop

1. Before engine shutdown, operate the engine between 1000 and 1200 rpm for at least 5
minutes to allow turbocharger cool down.
2. When operating temperatures are stable and the EGT drops below 1100°F (593°C), increase
engine speed to 1800 rpm for 15 to 20 seconds. Then decrease engine speed to between 1000
and 1200 rpm before engine shutdown
3. After the temperatures are stable, set the Ignition switch to the OFF position to stop the
engine.
4. When the propeller stops rotating, turn the Fuel Selector to the OFF position.
WARNING DO NOT TURN THE PROPELLER ON A HOT ENGINE EVEN THOUGH
NOTICE: An independent fuel shut-off valve is supplied by the airframe manufacturer in
compliance with engine shut-down integrity requirements.
5. During engine shutdowns, the EECS:
• Stops fuel injection with the next scheduled fuel event
• Schedules ignition events for a calibrated period of time or until the propeller has stopped
rotating, whichever occurs first.
6. When the engine stops, turn off the airframe power.
7. Refer to the airframe manufacturer's POH for additional information.

THE IGNITION SWITCH IS IN THE OFF POSITION. THE ENGINE
COULD KICK BACK AS A RESULT OF AUTO-IGNITION CAUSED BY
A SMALL AMOUNT OF FUEL REMAINING IN THE CYLINDERS.
AUTO-IGNITION COULD RESTART THE ENGINE AND CAUSE
SERIOUS BODILY INJURY OR DEATH.
