Pages 3-31 to 3-33 of the RFM revised. A red caption "Warning" for low MGB pressure now advises "A total loss of MGB oil pressure may result in a MGB failure in less than 10 minutes. If MGB OIL PRES is less than 5 psi, Land Immediately". Warning repeated at least once.
Some language to explain to white-shirt pilots that never poke under a cowling that the oil-bypass system won't save you if the reason for the oil leaking out of the MGB is in the gearbox housing itself. All S92 pilots should be gurus on this subject by now.
