Hello,

I got some bad pics of a MD-80 overflying and looking at them I noticed a yellow rectangle just after the leading edge on the underside of the right wing. I was wondering if this was a missing panel.?



Thank you for any insight.  

Jeff

It appears to be a fuel panel.....Usually the stripe is inside the panel door and visible when the door is open.

Yes, it's the fueling door. My guess is the door was replaced recently. It is unpainted and may have been heavily alodined, giving it a yellowish tint. Some patch repairs on the airplane have this look when they are first installed.

I think that panel is supposed to be painted that way, maybe its an MD thing?. Note this is a photo of an MD-11 that I took a few years back, but same thing:

I spent a week refuelling aircraft a few years ago (a few 77W's, A319's, 737's etc) and none of them had panels painted like that. I'd probably go with the unpainted theory (but I don't know much about fuelling panels!).

It's the fuel panel and it's not in an "unpainted" or primer state. MD-80s fuel panels are painted that way (alternating yellow & black stripes) to provide a quick look to see if the fuel panel is open or not.

At DL they are not painted yellow. The inside of the panel has orange reflective tape to show it's open. Same for the water service, oil service, and lav service door. I'm sticking with my replaced and unpainted hunch. They get damaged and replaced more often than any other panel on the wing.

Every DL MD 88/90 I have transfered fuel on, the outside door is no colored but the inside has the reflective stripe on the inside but on other MD model aircraft I have worked at G4 and Falcon Air Express the outside panel was painted yellow with black stripes

Excellent. I see where Allegiant uses one method for safety and DL another. It was an Allegiant MD-80 as nonfirm pointed out.

Thanks for all the info.

Very Informatory.....I wonder why the same logic was not applied on the Boeings/airbuses.although the B737/757 latches in the unlock position are painted reflective orange,but not an entire panel.
the only striped surface on a B737 would be the TE Torque tube in the MWW.

This could be an operator specific preference.Here is a pick of an Alaska 737-900 with the same thing.

It is not a required FAA marking, so your right, just operator preference.

Its funny you chose that plane to post, I just finished working a #2 engine bleed trip on it about two hours ago.
