Engine Cowling on Fokker E III

On the Eindecker, the engine cowling is obviously mounted to the firewall with a forward overhang. It is cut away on the bottom and the front lower portion to allow cooling air to enter and cool the jugs as the crankcase spins them past the opening. This got me wondering:
Does anyone have any references to cowlings coming loose during flight? I wonder especially about nose down maneuvers that would obviously trap a lot of air in the upper uncut away portion. Would that cause control problems or change handling characteristics?
Actually, was the cowling attached radially to the firewall only or were there extensions that anchored the sides and top more firmly?

Emmagee:
1. At about the location of the upper longeron, there were steel studs about 10mm in diameter, were attached the flange of the firewall.
2. At the bottom corners of the firewall were steel brackets fasten to the firewall face. These steel brackets had a right angle half round projection pierced with a hole for a bolt.
3. On the flange which projected aft 90°to the fire- wall was a groove for a cable.
4. On the cowling, there were two steel plates riveted to cowling rear edge that were pierced with a hole to receive and accept the studs on the firewall flange.
5. At an appropriate location near the rear edge of the cowling was a groove rolled into the cowling, that was positioned to coincide with the groove on the firewall flange.
6. A alumunum 90° flange was riveted on the inside
of the cowling, position in from the rear edge of the cowling to act as a stop against the face of the firewall.
7. A steel stranded cable with eye bolts at each would be layed in the groove in the rear edge of the cowling and passed through the holes in the half round projections at the bottom of the firewall. Nuts would be placed on the ends of the eyebolts, tightened and secured with another nut acting as a jamb nut,
8. Once the cowling was on, it could not move or rotate, it was firmly fixed in place. If the retaining cable was severed the cowling could come off.

Dan San,
Thank you for your illucidation of this problem that has been plagueing me for months.
