Narrative:

Departed the site to continue the flight back to our base. The problem arose after returning to base when I realized that in my haste to return that I had failed to make a proper logbook entry and signoff showing what I had done, as well as the aircraft being airworthy prior to departing for base. After arriving at the hospital a proper entry was made.
