Human Factors; Aircraft; Procedure
Take-off initiated with left cargo door opened. Initially; left pilot door was suspected to have unlocked during the take-off roll and/or ANC (Active Noise Cancellation) headset malfunctioning (in the past; ANC headset failure resulted in the same noise and vibration produced by the cargo door open). For that reason; realization about the left door unlatched status was achieved just after having lifted-off.Strong glare and a take-off facing the sun; plus habit to the more conspicuous annunciator panel of the legacy 208 version versus the G1000 CAS system made me miss the 'door unlatched' CAS message.A return to land was requested and a pattern performed normally. After landing and the runway vacated; the door was closed with no damage found. A runway inspection revealed that a spray bottle of window cleaner and a pair of headsets had been sucked out from the cargo door pocket and fallen in the pavement at the beginning of the runway.
C208 Captain reported the cargo door was not closed prior to departure. On take off; the cargo door opened causing an air turn back to secure the door.
