• On September 3, 2021, a Mooney M20K was destroyed when it impacted a pole, trees, and terrain after takeoff from the Arnold Field Airport. The pilot reported the engine's turbocharger did not kick in and acceleration was slow as he started the takeoff roll, but he disregarded the issue because he was on a grass field and near max gross weight. The plane continued to underperform after going airborne, and while the pilot cleared trees nearby, he couldn't clear the power lines. The pilot tried aiming for a sliver in the tree line to land, but the right wing clipped a phone pole and the aircraft came down. The probable cause of the accident was found to be the pilot's failure to abort the takeoff.^[4]
