Hi all. May be anybody "WIXers" know? What is on the hatch? Red sealant or paint stroke warning?
Regards, Vladimir.

Probably Sealant.
The panels close off the wing compartments.
These compartments are sealed and become fuel tanks. Also known as a wet wing.

That's what they are. I'm just happy that the SNICKERS diet paid of and I no longer fit in one of those usually 11X22 inch holes 
Nasty, smelly, dark dangerous places. Not sure about the rigidity of the CONNIES wing but I'd imagine it was stiff enough to have all or several access covers off in a check.
Boeing wings can have all the covers open without supporting the wings while MD-80's needed shoring as their wings are really slim and flexible. On the flip side, you'll need a hydraulic mule to run systems on an open wing Boeing aircraft in maintenance, or fuel in the wings to cool the skydrol and ANY Douglas can use the AUX Hydraulic pump with no fuel aboard to do systems checks thanks to what's called 'line loss' cooling as they use long open runs of tubing as a fluid to air cooling medium for SKYDROL. At the end of the check on a DC8/9/10/11 you replace the aux pump with a fresh one and away you go. And you haven't lived until you've had to lace up into place the center tank bladders in a 707 or early 727. We will speak no further about DC-8 volute fuel pumps.

Cool- lol.
Thank you. Maybe someone else will tell. Just about the "Zingers" diet is no longer necessary.
