D. Procedure
S 423-091
(1) Install the inlet and exhaust covers.
NOTE: Keep the engine covers in a warm location before you install
____ them on the airplane. Covers that are cold or frozen may be difficult to install, and may freeze to the engine inlet and exhaust.
At very low ambient air temperatures, the time for the engine to cool to -40°F (-40°C) can be greatly increased by the use of engine inlet and exhaust covers.
