Re: Corrosion within the laminate

Arnaud: Although the resolution is not great, I believe that your picture shows standard nuts, not nutplates. Nutplates would be riveted to the underlying metal strap, and be thinner in outside diameter than the nuts in your photo. The other thing which speaks against nut plates is that they would o...

Re: Corrosion within the laminate

Arnaud: Looking at the photo you show, I don't think that you can replace the screws without pulling the wing (at least a few inches). I thought that the screws went into nut plates, so they could be removed without internal access. The diagram and your photo show that the screws have washers and nu...

Re: Seeking advice on control stick "notch" in center and other MX issues.

Pete: With regard to your specific questions: 1) My ailerons had a slight grab or notch when I got the airplane. Turned out to be interference between the aileron control rod boot and the flap control rod boot at the fuselage sidewall. Not sure if the DA 62 control system is set up similarly, but if...

Re: ELT testing

Hi Greg: The 406 MHz signal can be tested, including position data, but requires special test gear. If your installation is done by an avionics shop, they should be able to do this. In my situation, I have verified that the GPS data does get to the ELT, and that the G-switch functions and that the E...

Re: ELT testing

I don't think that you want to radiate 406 MHz when testing your ELT. That will get the Rescue folks calling you. The ELT won't start radiating 406 MHz until 50 seconds after activation, which is plenty of time to receive a couple of 121.5 MHz sweeps.

Re: ACK 406 MHz ELT Update

The aural alert would be difficult to hear in most flying situations. One of the reasons that I usually have one of my radios tuned to 121.5. I do record the battery replacement dates in my maintenance reminder spreadsheet, and replace them when due. I just did the E-04 main battery and the sonic al...

Re: Corrosion within the laminate

Hi Arnaud: Hard to know what is the best course. If the corrosion is bad, you might have significant difficulty removing the screws. What would you do if you break one off and then have to extract the remaining portion? What I would propose is that you gently try to back the screws out. If they come...

Re: Water on the floor

I'm with Rich. Most likely intrusion point is the air vent hose on the right side of your photo. One other thought - the black rubber plug on the left front aspect of your footwell appears not fully seated. I'm not sure if the other side is exposed to an area that could support water intrusion... St...

Re: Corrosion within the laminate

One thing I have done since the airplane was new was to treat the exposed screws with LPS-3 a couple of times a year. I figure that this is drawn into the joint by capillary action, and may offer some protection. My airplane is away from moisture most of the time, in the hangar, with only occasional...
