PT 6 help

[CY333]

Hi guys.
We have an intermitted low oil pressure issue with a Meridian.

Going through the PT 6 manual, it refers you to do trouble shooting for the indicating system, by referring to the aircraft maintenance manual.

We can see that on the oil system and wiring diagrams , that there is a DAU (MEGGITT) installed between the screens and the oil pressure transducer.

We have not managed to locate any procedure regarding the test of the indicating system or the DAU, in any of the three manuals (Piper,Meggitt or P&W).

Has anyone got any idea where to look for this procedure?

Any help appreciated.

Hi , I would check the oil pressure with a master gauge , I did find a sender on an early B200 with a G1000 upgrade giving the pressure nearly exactly 20 psi low , also if the pressure was funny you may also get prop function and torque indication problems . I hope this helps . Regards

Hi,
The problem is intermittent ,so i am not sure that a master gauge would help.
It happens also only in flight
