Amateur-built PA-18 REPLICA accident near Willow, Alaska, October 24, 2021

On October 24, 2021 at about 2:25 am local time, a amateur-built PA-18 REPLICA, registered N368G, was substantially damaged in an accident during approach near Willow, Alaska (Minuteman Strip airport). It was a personal flight under general aviation rules (Part 91). 1 person was killed and 1 person was seriously injured. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

The pilot's exceedance of the airplane’s critical angle of attack while maneuvering for landing, which resulted in an aerodynamic stall and loss of control.

The NTSB's narrative final · quoted from the NTSB record

The pilot was landing his experimental, amateur-built airplane at a private airport when the airplane impacted terrain in a nose-down, near-vertical attitude short of the runway. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. No significant tree impacts were observed on the airframe. Based on the available information, it is likely that the pilot exceeded the airplane’s critical angle of attack while maneuvering for landing, which resulted in an aerodynamic stall and loss of control. At the pilot’s request, numerous design changes were incorporated into the wings, ailerons, and flaps of the accident airplane. The manufacturer of the kit and the designer of the flaps stated that they told the pilot and builder that the design changes were not recommended; however, the kit was built to the pilot’s specifications. It is likely that the design changes affected the stall characteristic of the airplane; however, the role those changes played in the accident sequence could not be determined.
