The NTSB's probable cause their words, unchanged
The pilot’s failure to maintain airplane control during initial climb with a crosswind when the airspeed decreased, the airplane exceeded its critical angle of attack and aerodynamical stalled at too low an altitude for the pilot to recover before the airplane descended and landed hard.

The NTSB's narrative final · quoted from the NTSB record
The pilot reported that during the initial climb from runway 08 with a crosswind, the airplane attained an altitude of about 50 ft above ground level when it encountered low level wind shear. The airspeed decreased, and the airplane stalled. The pilot attempted to recover airspeed by lowering the nose, but there was not enough altitude or time. The airplane subsequently landed hard substantially damaging the right wing and aft fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. About the time of the accident the reported wind was from 180o at 18 knots.

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 WPR21LA139.
