Engine Cowling Removal and Installation

Upper Cowling

Removal Procedure

  1. Parking brake: ON
  2. Fuel valves: OFF
  3. Generator switch OFF, Master switch OFF, Magnetos: OFF
  4. Unlock all four butterfly Cam-locks mounted on the cowling by rotating them 90deg counterclockwise while pressing slightly inward.
  5. Remove engine cowling being careful of propeller shaft passing through nose.
  6. For installation: place cowling horizontally ensuring proper insertion of alignment pins at base of nose.
  7. Secure fasteners applying light pressure, verify correct assembly and close Cam-locks.
WARNING Butterfly Cam-locks are closed when tabs are horizontal and open when tabs are vertical. Verify that tab is under the catch before closing.

Lower Cowling

Removal Procedure

  1. After removing upper cowling, position propeller horizontally.
  2. Using a standard screwdriver, press and rotate 90deg the two Cam-locks located on the lower cowling near the firewall.
  3. Extract the first hinge pin located on the firewall side, then, holding the cowling, extract the second hinge pin; remove cowling with downward movement.
  4. For installation follow reverse procedure.

  3. Verify no leaks in lubrication circuit, check oil tank level, ensure honeycomb radiator is not obstructed.
  4. Open both fuel valves, inspect fuel circuit for leaks, verify integrity of fireproof protection sleeves, drain circuit using container to collect fuel by opening specific drain valve located on firewall, close fuel valves. Verify no water or other contaminants.
  5. Verify integrity of engine mount silent-blocks.
  6. Verify connection and integrity of air intake system, visually inspect that dynamic air intake is not obstructed.
  7. Verify all parts are secure and safety wired.
UClose engine cowling.
VVerify that left side static port is not obstructed.
ZRemove tow bar and chocks.
NOTE Avoid blowing into the Pitot tube mounted on the left strut and into the airspeed system static ports as this could damage instruments.
NOTE The draining operation must be performed with the aircraft parked on level ground.
