Incident Summary
A pilot reported that during landing, the airplane was about to touchdown when he looked down and did not see the gear down lights. He then applied full power on both engines for a go-around, but the right engine did not come up to power. The airplane veered to the right. The pilot raised the flaps but did not raise the gear handle. The gear was later confirmed to be down and locked. The right propeller was not feathered. The airplane did not climb and impacted the terrain.
Pilot Report
The pilot stated that he initiated a go-around because he did not see the gear down lights. Upon applying full power, the right engine did not respond as expected, and the airplane began to veer right. He raised the flaps but left the gear handle in the down position. Despite these actions, the airplane was unable to climb and subsequently struck the ground.
Post-Accident Examination
After the accident, both engines were operated to approximately 70% power. Higher power settings were not possible due to the lack of suitable propellers. Investigators were unable to determine the reason for the loss of power on the right engine.
Findings
The gear was down and locked throughout the event. The right propeller was not feathered. No mechanical reason could be found for the right engine's failure to reach full power during the go-around attempt.
