PIPER PA-32R-300 — New Site, MS

What happened

Before departing on the accident flight, the pilot filed three instrument flight rules flight plans but had not requested nor received a weather briefing. A witness near the accident site reported a thunderstorm in the vicinity and observed the airplane enter a cloud followed shortly by a "loud pop." The witness then observed pieces of the airplane coming out of the cloud. The left wing and vertical stabilizer were located about 1,500 feet away from the main wreckage. Examination of the fracture surfaces revealed signatures consistent with tensile overload failure. No preimpact mechanical malfunctions were noted that would have precluded normal operation of the airplane.

Review of radar and weather data indicated the presence of thunderstorms along the route of flight, as well as in the vicinity of the accident site, with the potential for some of them to be severe. The satellite datalink weather product in the airplane cockpit uploaded weather data every 5 minutes and likely would have shown a thunderstorm cell increasing in severity to the highest intensity level near the time of the in-flight breakup. According to Federal Aviation Administration publication “General Aviation Pilot’s Guide to Preflight Weather Planning, Weather Self-Briefings, and Weather Decision Making,” datalink weather products are not as accurate or current as onboard weather radar, which provide real-time weather radar images in the cockpit. It is likely that the pilot attempted to maneuver around the weather hazard and inadvertently encountered a thunderstorm cell, which resulted in an in-flight breakup of the airplane due to overstress of the structure.
