The second half of the repair to the same Beechcraft King Air B200, following the rib and web replacement in the left-hand inboard wing.

The cause was the same: converting the aircraft from four-blade to five-blade propellers had raised vibration levels through the section between the engine and the fuselage, and the resulting fatigue had cracked the upper frame angle as well as the ribs and webs beneath it.

With the ribs and webs already renewed, the left-hand upper frame angle was removed and replaced to eliminate the remaining cracking and complete the repair of the section.
