Accident Overview

A pilot reported that the takeoff roll and liftoff were normal. However, shortly after becoming airborne, the airplane exhibited a lower than normal rate of climb.

The departure airstrip, measuring approximately 2,000 feet in length, is bordered by large trees. The field elevation is approximately 2,800 feet above mean sea level.

Mechanical Status

No mechanical malfunctions or failures were reported by the pilot. The aircraft's performance during the climb was noted to be below normal, but the cause of this reduced performance was not specified in the pilot's account.
