Sirs,
My AOA/Pitot probe has an unusual history in that it was given to me by you guys as a test unit when you were first developing them. As I remember I was up in Arlington working with Doug Medema on the compass calibration routine and he gave it to me to temporarily install. He then sent me a special D10 that recorded a bunch of stalls which I then sent back. And you guys didn't want the probe back so I've used it ever since, still temporarily installed.
Well, in doing a pitot/AOA/static check I've discovered that both the pitot and AOA leak internally in the probe. The unit is silicone filled and I'm not sure if it can be disassembled for repair or not? It also seems like it should not be leaking internally? But soap bubbles do emit out of the silicone when the pitot side is slightly pressurized. And the AOA side is clearly venting out of the bottom holes on the back of the probe.
It does read a few knots lower than my steam ASI, and did with the D10 and D10A.
Could you give me any some insight as to what my options are? It would also be helpful to know what the proper checks are for these units? Since it is a critical sensor it should have instructions for continued airworthiness.
Thank you
