Upon crossing the runway threshold, about 100 ft above ground level, he initiated a go-around, but the airplane "did not climb." The pilot then decided to land on the remaining runway. After touchdown, he applied full braking, but the airplane overran the end of the runway into a corn field. The airplane sustained substantial damage to the left wing and horizontal stabilizer. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. An automated weather observation station located about 7 miles from the accident airport reported that, about 20 minutes before the accident, the wind was from 280° at 8 knots. The pilot reported that, at the accident airport, about the time of the accident, the wind was from the northwest with rain. The pilot landed the airplane on runway 26. ## Factual narrative The pilot reported that, while climbing to jump altitude with skydivers onboard, they encountered "light rain" and he decided to postpone the jump and return to the airport.
