Human Factors; Procedure; Weather; Airport
We departed for a flight to ZZZ with one passenger on board. I departed with 2200 pounds of fuel. Enroute; about 25 minutes airborne; I had the right low fuel pressure light come on. I followed the procedure to see if the light would go out. It went out and then came on dim for the remainder of the flight. All gauges were normal and no indication that the engine was affected in its performance.On our descent to ZZZ there was another aircraft on the RNAV approach to Runway XX at ZZZ. I talked with him on Unicom after he had landed and he reported the weather was at minimums; but OK. I elected to make the RNAV approach to Runway XX. Over the final approach fix at 2300 feet; I configured the aircraft for landing. We arrived at the MDA which was 800 feet. The autopilot was activated and I was monitoring outside for visual clues and scanning the instruments as well. After about 20 seconds I started seeing ground with about 3/4 of a mile forward visibility. I started a slow descent looking for the runway and that was when the aircraft apparently struck the top of what I thought to be a tree branch. I immediately executed a go-around and once I was at a safe altitude; I started to assess what had happened; what was working and my next plan. Both engines were running and I raised the gear. Once airspeed allowed I raised the flaps to 0. I knew that ZZZ1 was VFR so I did a quick calculation and determined that I had enough fuel to go to ZZZ1. My airspeed indicator was inoperative and both navigation radios and communication radios were inoperative.I turned toward ZZZ1. The GPS was intermittent. I climbed to 7000 feet enroute. I could see damage on the right wing. I landed at ZZZ1 on Runway XX with light gun signals from the Tower.
Beechcraft King Air F90 pilot reported that while descending from an RNAV Approach MDA he struck a tree branch; executed a go-around; and diverted to a field that was VFR. The pilot observed damage to the right wing.
