Summary
On July 19, 2015, a Luscombe 8A (N45508) was involved in an accident near Oxford, IA. The accident resulted in 1 minor injury, with 1 person uninjured out of 2 aboard. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this accident to be: The pilot's selection of unsuitable terrain for takeoff based on the runway and density altitude conditions, which resulted in a runway excursion and impact with terrain.
The pilot reported that during takeoff, he applied full power and the airplane reached rotation speed. After liftoff, the airplane reached a height of about three or four feet and settled back to the runway. The airplane veered left, exited the runway, impacted a ditch, and came to rest inverted in a field. The airplane sustained substantial damage to the fuselage and wings.
The pilot reported the airplane was near maximum gross takeoff weight and he should have calculated density altitude before the flight. The pilot also stated he should have built up more speed before rotation.
Weather about the time of the accident was reported as 82 degrees Fahrenheit and winds were 250 degrees at 4 knots. The calculated density altitude was 2,923 feet.
This accident is documented in NTSB report GAA15CA193. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N45508.

Analysis
The pilot reported that during takeoff, he applied full power and the airplane reached rotation speed. After liftoff, the airplane reached a height of about three or four feet and settled back to the runway. The airplane veered left, exited the runway, impacted a ditch, and came to rest inverted in a field. The airplane sustained substantial damage to the fuselage and wings.
The pilot reported the airplane was near maximum gross takeoff weight and he should have calculated density altitude before the flight. The pilot also stated he should have built up more speed before rotation.
Weather about the time of the accident was reported as 82 degrees Fahrenheit and winds were 250 degrees at 4 knots. The calculated density altitude was 2,923 feet. The airport elevation is 750 feet and the runway heading was reported as 150 degrees true.
The pilot initiated the takeoff roll from a 1,400 foot turf runway that adjoined a 2600 foot asphalt runway.
The pilot reported no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
