Aircraft Accident/Incident Report

Waterloo, Iowa 50703
Wednesday, December 13, 2006 8:00 CST

NTSB Narrative Summary Released at Completion of Accident

The airplane made a hard landing during a visual approach. The pilot reported he applied engine power to soften the landing and the left engine "spooled up faster" than the right engine, which veered the airplane to the right. The pilot then reduced engine power again in order "to maintain control of the airplane." He stated that the airplane was still not aligned with the runway when it impacted the ground.

NTSB Probable Cause Narrative

The go-around not performed and the improper flare by the pilot during landing.
