Two maintenance covers are mounted under the fuselage, virtually on the belly of the Albatros.
The front one in the direction of flight allows maintenance on the oil pump of the Mercedes D.III engine.
On Albatros D.Va this maintenance hatch was mounted a little further forward in the direction of flight, as the oil pump on the Mercedes D.IIIa engine was mounted a little further forward.
The water pump was mounted on the D.IIIa engine where the oil pump was previously mounted.
The rear maintenance hatch provided access to the fuel drain cock under the fuel tank.
I used etched parts from HGW for the maintenance hatches on the model.

The flap for the fuel tank had to be adapted with a drill and file.


The two maintenance hatches were lightly rounded over a wide wooden handle of a brush and adapted to the fuselage contour

The drain cock was made from 0.8 mm plastic rod, 0.3 mm brass tubing and some copper wire for the small lever.
