PIPER PA 34-200

Full Narrative

On May 8, 2018, about 1315 central daylight time, a Piper PA-34-200 airplane, N99GN, collided with terrain following a go-around at the Porter County Airport (KVPZ), Valparaiso, Indiana. The flight instructor was seriously injured and the pilot receiving instruction had minor injuries. The airplane was substantially damaged. The airplane was registered to and operated by Griffith Aviation, Inc., under the provisions of 14 Code of Federal Regulations Part 91 as an instructional flight. Visual meteorological conditions prevailed for the flight, which operated without a flight plan. The flight departed Griffith-Merrillville Airport (05C), Griffith, Indiana, about 1000.According to information provided by representatives from the Griffith Aviation Inc. flight school, the pilot receiving instruction was performing approaches to KVPZ. The second approach was a simulated engine out approach to a planned go-around. During the go-around, the airplane's speed dropped below the single-engine minimum controlled airspeed as the pilot advanced the throttle of the operating engine to full power. He lost control of the airplane, and the airplane descended and collided with terrain.

Representatives from the Federal Aviation Administration examined the wreckage and did not find any preimpact anomalies which would have contributed to the accident. Substantial damage was sustained to the right wing spar and fuselage.
