General Maintenance Action
Aircraft; Human Factors
While preparing for a ferry flight; I opened and set the fuel panel for full tanks and while managing the single point refuel system; I noticed the safety chain on the fuel cap was broken and made a mental note to enter a writeup in the logbook. While the fuel truck was moved plane-side; the First Officer and I continued our preflight duties for a flight into a mountainous airport with deteriorating weather. The sooner we departed the better the weather would be on our arrival. This being said; we preformed what I believed to be very thorough exterior and interior preflight checks; cockpit setup; and briefings. Surprisingly ; upon arrival; I found that the Single Point Fueling Cap was missing. I immediately contacted Maintenance Control to see if there was a MEL relief for this situation and unfortunately there was none; requiring the aircraft to be AOG. I also called the FBO to inquire about or missing fuel cap. After a 10 min search the cap was found in the fuel truck where the fueler put it since the safety chain was broken. I also contacted the [Chief Pilot] to explain the situation and to ensure a 'Recovery ' was underway while my First Officer called Owner Services to do the same. Finally; although the aircraft was put into a hangar; my First Officer and I ensured the aircraft was winterized and made ready for the next crew. As the Pilot in Command; it was my responsibility to ensure the fuel cap was properly secured after fueling; and though I thought I had checked the panel a final time; I obviously failed. There is excellent training and ample SOP's devoted to minimizing unusual situations like this and can only say that that when you feel you have 'Checked' enough; check again.
EMB-505 Captain reported that an improper preflight resulted in the aircraft flying with a missing single point fuel cap.
