Narrative:

Departed unaware of a NOTAM restricting flts within a 30 mile radius of the denver area; which encompasses lmo near the 25 mile mark. Did not realize nor had the forethought to check NOTAM's or tfr's that may be in effect. My intentions for the flight were 'touch and goes' at lmo. After departure; I was immediately contacted by FBO via radio who had been contacted via telephone by the tsa to notify the aircraft taking off to land immediately. I was squawking 1200; and not a discrete transponder code that I would have been given had I checked the tfr and contacted denver TRACON as instructed by the NOTAM and tfr. This was clearly my mistake. After being notified of the tfr; I immediately landed on runway 29. I was no more than a 1/2 mile radius from the center of the airport but now realize the severity of the incident. Upon landing; I exited the runway and shut down on the taxiway to await instructions from tsa inspector. The entire situation was an unintentional yet avoidable mistake made on my behalf by taking for granted my normal procedures because I was at my local airport practicing lndgs. I now know that regardless where I am; it is a mistake to take-off anywhere without reviewing all NOTAM's; tfr's and all relevant information.

Title: SR22 PLT TAKES OFF FROM ARPT UNDER A TFR.

Narrative: DEPARTED UNAWARE OF A NOTAM RESTRICTING FLTS WITHIN A 30 MILE RADIUS OF THE DENVER AREA; WHICH ENCOMPASSES LMO NEAR THE 25 MILE MARK. DID NOT REALIZE NOR HAD THE FORETHOUGHT TO CHECK NOTAM'S OR TFR'S THAT MAY BE IN EFFECT. MY INTENTIONS FOR THE FLT WERE 'TOUCH AND GOES' AT LMO. AFTER DEP; I WAS IMMEDIATELY CONTACTED BY FBO VIA RADIO WHO HAD BEEN CONTACTED VIA TELEPHONE BY THE TSA TO NOTIFY THE ACFT TAKING OFF TO LAND IMMEDIATELY. I WAS SQUAWKING 1200; AND NOT A DISCRETE TRANSPONDER CODE THAT I WOULD HAVE BEEN GIVEN HAD I CHECKED THE TFR AND CONTACTED DENVER TRACON AS INSTRUCTED BY THE NOTAM AND TFR. THIS WAS CLEARLY MY MISTAKE. AFTER BEING NOTIFIED OF THE TFR; I IMMEDIATELY LANDED ON RWY 29. I WAS NO MORE THAN A 1/2 MILE RADIUS FROM THE CENTER OF THE ARPT BUT NOW REALIZE THE SEVERITY OF THE INCIDENT. UPON LNDG; I EXITED THE RWY AND SHUT DOWN ON THE TXWY TO AWAIT INSTRUCTIONS FROM TSA INSPECTOR. THE ENTIRE SITUATION WAS AN UNINTENTIONAL YET AVOIDABLE MISTAKE MADE ON MY BEHALF BY TAKING FOR GRANTED MY NORMAL PROCS BECAUSE I WAS AT MY LOCAL ARPT PRACTICING LNDGS. I NOW KNOW THAT REGARDLESS WHERE I AM; IT IS A MISTAKE TO TAKE-OFF ANYWHERE WITHOUT REVIEWING ALL NOTAM'S; TFR'S AND ALL RELEVANT INFORMATION.
