Great Falls International Airport
Aircraft Accident/Incident Report

Great Falls, Montana 59404
Monday, July 13, 1998 14:36 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was executing a landing to runway 21 at the Great Falls International airport and reported that 'approximately 10 to 15 feet above the runway, the plane dropped suddenly, hitting the runway hard and starting a series of bounces-each bounce progressively higher-that I attempted to control with elevator and power. At the time, I was able to keep the plane straight down the runway but was being blown to the left by the cross wind. After the fourth bounce, I opted for a nose down landing in the face of my greater concern of leaving the runway and flipping the aircraft.' Tower controllers reported that they observed the aircraft begin porpoising with increasing severity during which the nose landing gear collapsed. The 1435 surface weather observation taken at the Great Falls International airport on the date of the accident reported winds from 230 degrees magnetic at 22 knots gusting to 30 knots.

NTSB Probable Cause Narrative

The pilot-in-command's improper remedial action and overload of the nose landing gear. Contributing factors were gusty winds and a pilot-induced oscillation (porpoise).
