The pilot of a Piper L-4 airplane reported that shortly after he started the taxi roll from the parking area, he initiated a shallow turn toward the taxiway. As he reached the taxiway he steered to follow the centerline, however, the airplane continued to turn to the right. He reported, in part, that the left brake inputs were not responsive and the airplane continued to the right and collided with a standing occupied Cessna.
The pilot was returning to the departure airport following the release of skydivers. The airplane was on a straight in approach to the runway during windy conditions when the engine lost power. The pilot applied full throttle but the engine did not respond.
