Analysis

The pilot reported he was landing on a 1700' airstrip that he had routinely used. He said he landed slightly short & below the runway grade, striking the right main landing gear on the lip of the runway. The right main gear failed & separated from the wing, damaging the wing spar. The pilot said he had some difficulty with the approach to landing due to sunglare. On a subsequent application for med cert, dated 3/28/90, the plt rprtd 8000 hrs of flt time.
