Hmm, I've gone through each month between 1941 and 1945, for overseas accidents, and there is no single incident that comes anywhere that number of losses for a single date/base:

Though the home base losses are not complete, the site claims 100% of overseas accidental losses are listed.
Now, I just need to check the USN losses - maybe tomorrow as I've gone a bit cross-eyed scanning the above pages.
