Background
A student pilot, who was already a rated pilot, and an instructor landed on an unimproved private airstrip. The strip was located at an elevation of approximately 4750 feet above mean sea level.
Pre-Takeoff Considerations
After landing, the two pilots walked the length of the airstrip and discussed its condition. They observed tall grass on the right side of the strip, three bushes on the left side, and a ditch approximately 800 feet from the approach end. Additionally, four dogs and three horses were present in the vicinity. The pilots decided that during takeoff they would angle slightly across the runway. Their initial concern involved the location of the animals.
Takeoff and Sequence of Events
After starting the takeoff roll, the student pilot angled the aircraft further to the left than the instructor had anticipated. As a result, the left wing struck one of the bushes. The aircraft then veered to the left. The instructor attempted to regain control, but was unable to do so before the aircraft struck two additional bushes.
