Departure and Conditions
The pilot departed from runway 08 during local thunderstorm activity. The runway had an uphill gradient of 2.2 percent. The pilot reported that winds were from the southeast at 10 to 15 knots.
Takeoff and Initial Climb
During takeoff, the pilot raised the landing gear at approximately 50 feet above ground level (agl) and retracted the flaps. Except for light turbulence, the takeoff was uneventful until the airplane reached an altitude of about 75 to 100 feet agl.
Descent and Response
At approximately 75 to 100 feet agl, the airplane started descending. The pilot applied full power and increased the pitch attitude, but was unable to arrest the descent. When the pilot realized the airplane was going to contact the ground, he extended the landing gear.
Propeller Strike and Aborted Takeoff
Before the landing gear was fully extended, the propeller struck the runway. The pilot noted a resultant vibration and elected to abort the takeoff. The airplane then traveled beyond the departure end of the runway and encountered rocky terrain.
