R44 with EDM-830 shows overhot CHTs
My R44 Raven1 (with 3rd party floats) had a forced landing with 4 POB onto a beach shortly after takeoff from same beach. Next day it was determined that 2 inlet valave had failed. Remaining cylinders were removed and sent to engine shop where they found issues with valve guides in other cylinders. Total time was 285 hours and still 4 months to run on Warranty. However Lycoming are refusing to honour warranty.
At my request a JDI EDM-830 engine monitor was fitted when the six new cylinders were installed. We now have a lot of data on the engine CHT and EGT temps, plus MAPs etc.
The data we have recorded shows that when flying MAPs of 22, 23, 24ins that the CHTs on some cyldinders exceed the max recommended by Lycoming of 435deg F throughout the flight. Yet Lycoming want high MAPs during run-in. From our data this is not possible in our Raven 1. Does anyone else know of an engine monitor fitted to an R44? If so, what CHT temps are they recording?
