79-01-00 Christen Inverted Oil System
Description and Operation
The standard Christen 801 Inverted Oil System is a kit-form
accessory for Lycoming aircraft engines which permits
normal engine lubrication, with minimal oil loss, during
aerobatic flight. When installed, it becomes a self-contained
extension of the normal aircraft engine oil and breather
systems. As the system control valves are gravity-operated,
no connection to aircraft power sources is required (refer to
figure 1 and 2).
The system works in all inverted and negative-g flight condi-
tions and is particularly suited for high-performance aircraft
used for unlimited-class aerobatic competitions.
The need for modification of the standard Christen 801
Inverted Oil System results from installation requirements
for different system components of the Lycoming engine.
