Narrative:
During takeoff, the upper engine cowling came off my aircraft. Based on my training and experience as an a&P mechanic, I believe that the engine cowling hinge broke. The director of maintenance said that the latches were not secured and that I did not do a proper preflight or I would have discovered that the latches were not secured. I performed my preflight as stated in the airplane flight manual. To prevent recurrence all our aircraft cowling latches will be painted 'day-glo' orange on the sides of the latches so if they are open it will be easier to see.
