Probable cause

The pilot's failure to maintain altitude/clearance while on final approach for landing.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

According to the pilot, "the purpose of the flight was to test a new instrument and conduct test approaches and landings to check flying characteristics at slower approach speeds. Previous approaches at 70 miles per hour (MPH) [were] too fast. After practicing slow flight and entering a stall speed into new instrument I was cleared for a 5-mile straight in approach to runway 2. After "dragging in" for 5-miles I attained my test final approach speed of 60 mph. There was a tree in my glide path so I climbed over it but underestimated my sink rate (which was the purpose of the test flight) the right gear snagged a limb which jerked me into a right hand roll. I applied power, leveled the wings, and pointed [the] nose ahead as it hit the ground. There were no visible markings on the runway to indicate a displaced threshold. The reason for the displaced threshold is the tree. If the runway was properly marked, I am sure I would have been reminded at least a mile out or one-half out that there was a displaced threshold and avoided the incident."
