Not unless the gun is being fired manually. The TBM Avenger was equipped with an electrically operated Grumman 150SE-1 or -2 Ball Turret which has a built in mechanism in the turret ring that prevents firing through a certain arc.<ref>{{cite book |title=Aircrewman's Gunnery Manual |date=1944 |page=T-19}}</ref> | Not unless the gun is being fired manually.

According to the TBM Pilot’s Handbook: “Interrupter cams actuate a micro switch in the gun firing circuit automatically stop the firing of the turret gun when the tail and wing surfaces are in [the] line of fire.<ref name="PHFOITBM">{{cite book |title=Pilot’s Handbook of Flight Operating Instructions: Navy Model TBM-3 Airplane |date=1945 |page=53}}</ref> | According to the TBM Pilot’s Handbook: “Interrupter cams actuate a micro switch in the gun firing circuit automatically stop the firing of the turret gun when the tail and wing surfaces are in [the] line of fire.<ref name="PHFOITBM">{{cite book |title=Pilot’s Handbook of Flight Operating Instructions: Navy Model TBM-3 Airplane |date=1945 |page=53}}</ref> The Erection and Maintenance Manual for the airplane further explains how to "zone", or calibrate, the turret by mounting a portable light to the muzzle of the gun to visualize its field of fire and therefore determine dead zones.<ref>{{cite book |title=[Erection and Maintenance Manual for TBM-3 Aircraft |pages=117–119 |url=http://app.aircorpslibrary.com/document/viewer/nov4tbmihol |access-date=1 November 2022}} The cover on the copy consulted was missing, so the title has been inferred based on similar manuals.</ref> | ||
A track around the circumference of the turret is shaped to follow the contour of the fuselage. A moveable arm which is electrically connected to the main turret control switch will ride on the track, when the gun is depressed, automatically limiting the angle of depression of the gun as the turret revolves.”<ref name="PHFOITBM" /> | A track around the circumference of the turret is shaped to follow the contour of the fuselage.
