Analysis

During arrival, the plt was advised of the position of a Boeing 727 that was landing on rwy 29R & he reported seeing theacft. He also was cautioned about possible wake turbulence from the Boeing & he acknowledged. The plt reported that while he was on an approach to land, about 2 mi from the arpt, his Beech H35 suddenly pitched up & flipped over. He recovered, was able to continue the approach and landed safely. An exam after landing revealed that the v-tail was damaged. The inboard leading edge of the right stabilizer was deformed downward about 1 3/4 inches & its lower skin was buckled between the front & rear spars. The front spar of the right ruddervator was twisted & there was skin deformationon both ruddervators. Investigation revealed the Beech had crossed the path of the large acft at aprx the same alt & about 60 to 65 sec later. The speed at the time of the upset was aprx 160 KTS. The maneuvering speed was 124 KTS IAS. The aim rcmds 2 min sepn behind a large acft when landing on the same rwy or a parallel rwy within 2500 ft.
