During Departure, The Airplane Failed To Accelerate Past 40 Knots
The pilot reported that he was departing a remote off-airport landing site in his tailwheel equipped airplane. After assessing the physical site, which was sloped on both ends and the current weather conditions, he selected a takeoff direction and a takeoff abort point. During the departure roll, the airplane failed to accelerate past 40 knots, exited the departure area and impacted brush and trees. The airplane sustained substantial damage to both wings. The pilot reported no preaccident mechanical failures or malfunctions that would have precluded normal operations.
