What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Aircraft took off for a banner tow mission from Trenton Robbinsville Airport (N87). The pilot made two unsuccessful attempts to pick up the banner. The third pick up attempt was successful, and as the aircraft climbed, the engine lost power and began to smoke. The pilot released the banner, and was able to return to the airport without further damage. Inspection of the engine, post-flight, revealed a hole in the cylinder head, adjacent to, and through the bottom spark plug hole on the #5 cylinder.
