N41517

The private pilot was asked to perform a power off 180 degree accuracy landing as part of the practical test for a commercial pilot certification. The first attempt was terminated with a go-around. The second approach appeared normal according to the designated pilot examiner onboard, until approximately five seconds before touchdown. At that point the airplane rate of decent increased to approximately 1000 feet per minute and the airspeed slowed below 75 miles per hour and the airplane "dropped onto the runway." Neither the pilot nor examiner noticed any apparent damage at that time and elected to continue the flight. Upon completion of the flight the airplane was examined by maintenance for a hard landing and substantial damage was confirmed to both wings at the landing gear assmbly mounts.
