Instrument Panel Material

[Skypunk107]

Anyone know off the top of their head, and actual drawing, parts manual, or actual application data preferred  ... what alloy and temper the instrument panels in M20B are fabricated from?  7075 T6, or 2024 T4 sound good to me, but I'm a do it right, or don't do it type.

 

Garmin went and appvd GNX 375 for A&P install so my need for a new panel got bumped up by about $3K ...

I don't think Mooney list materiel anywhere in IPC, only on their drawings and parts list that are not valuable to us.

For this type of application we would use 2024 T3 or T4 clad sheet. 7075 T6 is really higher strength alloy not needed here, however I used it on my panel as the manufacturer didn't offer Al 2024 at the time.

Email Frank Crawford at Mooney and he can look it up for you.

I used .090 6061 when I did mine last year, in a C model.

The panel is not a structural member so I would just use 6061-T6.  Anodyne it before installing.  If you are really worried about corrosion use the double clad 2024.

Thanks fellas.   Wasn't thinking clad would be a route I'd go.   That 99% pure Al can jump up some prices.  Plus after Alodine I'd hit it with some prime n topcoat and toss the cover so it's one piece.

 

How do I get Frank Crawford's email address?

 

Have a GI 275 I Eng Monitor I need to get installed to, so lots of holes to disappear, and the ADF and Xpnder on far right side gots to go...
