A China Southern Airlines Boeing 787-9 Dreamliner experienced a hard landing and tailstrike accident at Guangzhou Baiyun International Airport, resulting in significant structural damage. The copilot, transitioning from ERJ-190 aircraft to the Boeing 787, was operating manually and was nearing the final approach. The aircraft rapidly sank before touchdown, exhibiting a pitch attitude of 5 degrees and a vertical load of 1.36G. The pilot initiated thrust reversers, leading to a bounce to a height of approximately 3 feet. The crew continued to apply control inputs, resulting in a 7.6-degree angle of attack and a vertical load of 2.47G.A China Southern Airlines Boeing 787-9 Dreamliner experienced a hard landing and tailstrike accident at Guangzhou Baiyun International Airport, resulting in significant structural damage.
