| Subject: | Re: "Burping" The Oil System in the 912 Engine |
Rotating the prop ONLY in the normal operating direction May be advised in
order to 1. fill oil tank to check oil level properly, 2. prevent pushing
air into oil delivery passages due to turning prop backwards, and 3.
prevent air from being sucked into oil passages because header tank is
empty and suction tube might draw air instead of oil. At least these are
the explanations I recall from the Lockwood maint course.
