From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

General aviation airstrip IA23 is a privately owned grass strip. The center line is not marked.

The pilot stated that he was lined up on short final. As he came over runway 17 the aircraft suddenly dropped. He stated that "it was like an elevator, straight down". The left wing of the aircraft impacted a street sign post at approximately mid-span on the wing. The sign was located approximately 10' off of the road, approximately 20' - 30' before the runway 17 threshhold and approximately 30' - 40' to the left of the approximate center line of runway 17.

According to ground scarring, the aircraft contacted the ground at the same time it contacted the road sign. The aircraft was left of the runway center line approximately 30' - 40' and angled approximately 20 degrees to the left. The aircraft bounced and contacted the ground approximately 15 - 20 feet further along the path of travel. The outer half of the left wing separated from the aircraft and came to rest on the ground approximately 30 feet beyond the point of impact. The aircraft, sliding on the ground, continued on and came to rest upright, approximately 200 feet further along the path of travel.
