During a visual approach, the airplane made a hard landing after the pilot reported asymmetric engine spool-up causing a veer to the right, then reduced power to maintain control.

Accident Summary

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

Pilot Report

According to the pilot, the asymmetric engine response occurred when he attempted to add power. The left engine's faster spool-up generated a yawing moment to the right. The pilot's subsequent reduction of power was intended to regain control, but the airplane remained misaligned with the runway at touchdown.
