In 1912, Petrović was one of six Serbian military personnel selected to undergo training at Henri and Maurice Farman's flying school in Étampes, near Paris. Following his completion of the training program, the "Fédération Aéronautique Internationale" (FAI) issued Petrović with pilot's license #979, making him one of the first 1,000 pilots certified by the organization. Upon completing his training, Petrović returned to Serbia, together with the other newly certified Serbian pilots. During the Siege of Scutari (modern-day Shkodër, Albania), Petrović was embedded with the nascent Serbian Air Force's newly formed Littoral Air Detachment, which was tasked with carrying out reconnaissance missions over the city and its surroundings. In March 1913, Petrović fell out of his Farman HF.20 while completing a mission over the city, and was killed. His death negatively affected the morale of his unit. Under pressure from the Great Powers, Montenegro and Serbia retreated from Scutari in May, the Littoral Air Detachment ceased conducting flights over the city and its pilots returned to Serbia.
