Analysis

During apch the crew was advised of a windshear on final apch of +10 to -15 KTS at 700 ft & 400 ft AGL. Winds were reported 170 deg at 26 KTS gusting to 40 KTS. The plt added 20 KTS to his v-ref speed of 132 KTS & selected auto-spoilerdeployment. Prior to touchdown crew was advised again of a windshear alert in several quadrants. After touchdown the acft bounced & the auto-spoilers deployed. The acft touched down again in what the crew described as a firm landing. Theflt engr found no apparent damage so the crew did not write it up as a hard landing. On 12/31 damage was found on the upper crown of the fuselage between stations 660 & 680 from stringer S-10 left to S-10 right. Later inspections revealednose gear damage also. Flt recorder read-out indicated that the approach speed varied from 143 to 170 KTS with a touchdown speed of 163 KTS. Significant windshear existed below 1,000 ft MSL & moderate to severe turbulence existed below 5,000 ft MSL. Updrafts & downdrafts existed below 100 ft AGL due to convergence/divergence of the winds.
