Low Oil Pressure - Other Guages Normal

Post by pelmet »

What does Cessna say to do in such a situation. May not want to trust them......


C-GGSG, a Cameron Air Services Cessna TU206G equipped with amphibious floats was conducting a VFR flight from Mill Lake, ON, to Billy Bishop Toronto City Airport (CYTZ), ON, with only the pilot on board. Shortly after takeoff during cruise flight, the oil pressure gauge indicated a reading below the green arc. As all other engine parameters remained within normal limits, the pilot elected to continue the flight. However, en route, the pilot heard approximately four loud banging sounds before the oil filler access panel opened unexpectedly. Oil subsequently began leaking from the engine, spraying the windshield and obstructing visibility. The pilot declared a Mayday to Air Traffic Control (ATC) and directed the aircraft toward a farmer’s field near Linton, ON, for a forced landing. After extending the landing gear, the aircraft landed in the field. The aircraft sustained substantial damage to the tail and floats, and a fence on the farm property was also damaged. The pilot was not injured. Post-incident inspection by the company’s maintenance team revealed a large hole in the top crankcase of the Teledyne Continental IO-550-DCF engine, specifically in the area of cylinders 5 and 6.

Cessna tells you to continue the flight with low oil pressure indicating?

A U206G POH that Google found has no low oil pressure checklist, but has the attached expanded procedure which continues to say if there is a total oil pressure loss and oil temperature also rises to make a forced landing with minimal engine power as an engine failure is likely imminent.

The very fact that 'gauge' is spelled incorrectly leads me to highly suspect the legitimacy of that. :rolleyes:

Gage and gauge are both English terms. Gage is predominantly used in American (US) English while gauge is predominantly used in British English.

Cessna is a American brand so it would be normal for their manuals to have been written using American Spelling.

Exactly. Like Tyre or Tire.

Color vs colour. License vs licence.

There’s a million different examples.

The above reference from the POH does say that an inspection at the nearest SUITABLE airport is advisable to be completed. Not necessarily continue the flight.

Awww poor GSG. I’ve got hundreds of hours in that plane; it was definitely the better of the two 206s there :(

If an oil pressure gauge reads close to zero, decrease the prop rpm acfew hundred and see if the propellor governs with power changes. If it does, the engine has oil
pressure.
