NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.
The flightcrew reported that the landing was into the early morning sun approximately 30 minutes after local sunrise. They reported that the glare from the sun was intense and the flying pilot installed his windshield sun shade at the other marker. They said that the 1,000 foot and 500 foot call outs were made with confirmation of the runway in sight. The flying pilot continued to fly on instruments to decision height. They said that at approximately 1,000 feet the glare increased with low haze and the forward visibility decreased. The flying pilot considered the airplane to be in the correct attitude for landing; however, the non-flying (PIC) took control prior to touchdown and flared the airplane when he saw no apparent flare. The airplane then touched down hard. A readout of the Flight Data Recorder revealed touchdown produced 2.77 'G.' The data indicated that the sink rate increased when the non-flying pilot moved the control column aft in an attempt to flare the airplane.
The National Transportation Safety Board determines the probable cause(s) of this incident to be: the pilot-in-command's (non-flying pilot) improper flare. Related factors were inadequate crew/coordination, haze and sunglare. Full narrative available
