Williamstown, NJ, USA

Aircraft #1

N48408

Grumman G164A

Analysis

After takeoff, the pilot determined that the weather was worse than reported, and he returned to the departure airport. While on final approach, the airplane began to "settle," and the pilot was "slow" in his response. He added power, but the airplane struck wires and terrain prior to the approach end the runway. When asked about the performance and handling of the airplane, the pilot responded, "The airplane was fine. The engine was running perfectly. I'm not blaming anyone but me." In a subsequent conversation, the pilot added that he managed the airport, knew the wires were there, and that they were marked.
