Airspace Structure; Human Factors; Procedure
I conducted Weather Check and checked for TFR's on FAA website as part of my preflight planning. Departed the heliport for our daily local security patrol. After establishing 2 way radio communication with BUR ATC; I was advised of a possible pilot deviation and given a phone number for ATC. Upon completion of my assigned flight; I contacted ATC via telephone. I passed on my contact information and certificate number. A possible TFR violation was mentioned and is being investigated.I was aware of a TFR in the area North of SMO. This TFR was extended by 45 minutes while I was flying. At the time I checked TFR status; [the FDC] had dropped off the FAA website. Maybe it was in the process of being updated; I do not know. I have been using Flight Vector in the past; but I would suggest to use at least 2 or 3 sources when inquiring about TFR status to avoid problems of this nature.
Bell 206 pilot reported a TFR incursion when the TFR was extended beyond the planned time frame.
