Thanks for the info! Anyway, admitting that my gunnery and attack skills are mediocre at best, you can see on the attached image that first I disabled the tail gunner, went closer (<150m), and attacked exactly those vulnerable parts you suggested (cockpit, wingroot, engines). I was flying a Tomahawk IIRC. Probably my attack was not steep enough to hit anything vital well inside the plane's structure, but I'm pretty sure that the engine cowlings (which remained intact) got the same amount of bullets as the inner wing area nearby.
