The NTSB's narrative final · quoted from the NTSB record
During a post-maintenance test flight after an engine overhaul and annual airframe inspection, the pilot retracted the landing gear as he departed the runway. While on the downwind leg of the airport traffic pattern the pilot lowered the landing gear handle, but the landing gear remained retracted and stowed and the associated green indicator light was not illuminated. The pilot attempted to troubleshoot the anomaly and eventually performed an emergency landing. The airplane touched down on the partially extended nose landing gear and fuselage, resulting in damage to the left horizontal stabilizer and elevator. Postaccident examination of the landing gear system revealed that the left main landing gear actuator retaining ring separated from the actuator cylinder, exposing the internal rod and O-rings. The separation exposed a hole in the cylinder and a loss of hydraulic fluid followed, leaving the system unpressurized. The lack of system pressure resulted in the failure of the nose landing gear door actuator assembly and the subsequent gear-up landing. The retaining ring inside the actuator cannot be visibly inspected due to the position of the seat being recessed into the cylinder. The actuator does not have a specified overhaul time or cycle limit.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number WPR23LA012.
