Aircraft Accident/Incident Report

Broomfield, Colorado 80021
Friday, August 7, 1998 14:07 MDT

NTSB Narrative Summary Released at Completion of Accident

The recently certificated private pilot of 10 days was cleared to land on runway 11R. The wind was from 360 degrees at 5 knots. He used 20 degrees of flaps and an approach speed of 70 knots. The airplane landed hard and began to porpoise. The pilot said he 'could not keep the airplane on the ground so [he] applied forward pressure, this time hitting the nose gear.'

NTSB Probable Cause Narrative

The pilot's improper remedial action after making a hard landing and porpoising. A factor was his lack of total experience.
