Narrative:

Just after takeoff from sjt, the l-hand forward nose cargo door floated open and closed. ATC was notified and a clearance to return for landing was received. After landing the door was found to be in good condition and closed. The flight was continued without incident. The cause of the occurrence was due to my improper fastening of the 2 latches that secure the door. I was previously warned to pay close attention to these types of latches. I was told that at times they can appear to be secure, when in actuality they are not. Without question, I will pay more attention to these latches in the future. Callback conversation with reporter revealed the following information: no additional information was gleaned from the callback. The reporter did state that his preflight now includes a forceful attempt to dislodge the cargo door latches.
