Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

NTSB Number
GAA16CA264
The flight instructor reported that during an instructional flight, while on short final, the headwind dissipated and the airplane started to slow and sink. He instructed the pilot receiving instruction in the front seat to add power, but she did not complete the action immediately. After realizing the action was not complete the flight instructor added full power, but the airplane continued to descend at an accelerated rate and touched down hard upon landing. Subsequently, the main landing gear collapsed and the fuselage was substantially damaged. The flight instructor did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot receiving instruction's failure to maintain proper airspeed and descent rate, and the flight instructor's delayed remedial action during the landing flare, which resulted in a hard landing and landing gear collapse.
