Thank you. I remember seeing similar parts on another plane, (I don't remember the name of that plane), but they had holes in them.

Many American Navy dive-bombers had holes in their dive brakes, like the Douglas SBD and Grumman TBF.
The dive brakes functioned differently than their flaps.
Here a couple of examples ...
The Northrop BT ...
the dive flaps at the neutral position ...
the bottom part of the diving flps lowered down working as the landing flaps ..
both the top and down parts of the diving flaps at the position working as the air brake ...
The Curtiss SBC Helldiver ...
the bottom part lowered down as the landing flaps ...
the top and bottom parts fully opened working as the air brake ...
The Douglas SBD Dauntless ...
the neutral position ...
and the bottom parts lowered down as the landing flaps ...
and a diving SBD with fully opened diving flaps working as the air brake
the pic surce : the internet.

The one I saw was an SBD, although I didn't see this part in it, what was it for?

Retractable tail hook for landing on an aircraft carrier. The hook snagged one of several cables strung across the flight deck thus stopping the aircraft in a very short distance

I understand.

Just a correction, the Grumman TBF did not have dive flaps, flaps with holes in them.

Great pictures, Wurger! Thanks.
Another nice image of landing SBD Dauntless. Her landing flaps and the arresting hook are lowered down. There can be noticed one of the brake cables strung across the flight deck.
the pic source: the net.

It seems that there was also a variant for land, this is one that my country bought.

Actually that's a Navy SBD Dauntless finished as A-24B Banshee for the Mexican Air Force. The A-24 just lacked the tailhook and used a larger pneumatic tailwheel. A-24s were supplied to Mexico for anti-submarine patrol beginning in 1943.

That's right, it's a shame that the FAM didn't keep any.

I guess I should have worded that better, the TBF had "brakes" that steadied it during a torpedo run or a bombing run from a shallow dive. This was accomplished by their flaps extending to the full 40° position.
It's when the flaps are in this position (fully extended), you can see the holes in the lower flaps.
Yes, but the holes do not go through the flaps. I imaging the are just lightning hole pit in for strength and weight savings. Never noticed them before.

Not sure if the holes were to save weight or to create more "disturbance" to the airflow when fully extended?
