Incident Overview
According to the pilot, during the takeoff roll, a vehicle entered the runway. The pilot immediately pulled back on the yoke to climb and avoid the vehicle. As the airplane began to rotate, the pilot simultaneously retracted the landing gear. The pilot reported feeling a "bump" before the airplane lifted off the runway. The airplane ascended over the incursion vehicle, and the pilot avoided a collision.
Post-Flight Inspection
During the post-flight inspection, the pilot checked the landing gear for damage and found no deficiencies. However, during a subsequent preflight inspection by another crew, damage to the lower aft fuselage was noticed. The airplane sustained substantial damage to the bottom aft fuselage longerons and stringers.
Mechanical Status
The pilot reported that there were no mechanical failures or anomalies prior to or during the flight that would have prevented normal operation.
