Aviation safety reports, made easier to study

NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.

The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.

The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

The pilot reported that while in cruise flight, the airplane’s engine started to run rough. He applied carburetor heat, and the engine operation smoothed out. Less than a minute later, the roughness returned, and the engine lost all power. Unable to maintain altitude, the pilot attempted to land in a nearby field. The airplane collided with a fence during the descent and came to rest in a field with rough ground. The airplane sustained substantial damage to both wing assemblies. A postaccident examination and engine test run revealed no mechanical anomalies. Weather conditions near the accident site were conducive to carburetor icing at glide and cruise power settings. Although the pilot applied carburetor heat following the engine roughness, it is likely that the ice accumulated to the degree that the carburetor heat was insufficient to maintain full power.

NTSB Probable Cause

The loss of engine power due to the formation of carburetor ice as a result of the pilot’s delayed application of carburetor heat.

Full Narrative

On July 18, 2024, about 1835 eastern daylight time, a Cessna 182C, N8523T, was substantially damaged when it was involved in an accident near Zephyrhills, Florida. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot reported that after departing Tampa Executive Airport for a round-trip flight, he made a touch-and-go landing at Cross City Airport. While en route to Zephyrhills Municipal Airport for a fuel stop, the airplane’s engine started to run rough. He applied carburetor heat, and the engine smoothed out briefly before losing power again. Unable to maintain flight, he pitched for best glide, declared an emergency to air traffic control, and attempted to land in a nearby field. The airplane collided with a fence during the descent and came to rest in a field with rough terrain. Examination of the airplane revealed substantial damage to both wing assemblies. The engine remained attached to the fuselage. The fuel system was found to be intact, with no breaches or damage, and no fuel contamination was detected. After connecting the battery, the engine was successfully started and ran normally. The magnetos were tested, showing a normal rpm drop. Throttle continuity was established and the engine responded normally to throttle adjustments. After the engine run, the spark plugs were inspected and showed normal coloration, consistent with the Champion Spark Plug chart. No anomalies were found that would have prevented normal operation. The reported weather conditions about 3 nautical miles from the accident site included a temperature of 89° F and a dew point 77° F. When plotted on a carburetor icing probability chart, the airplane was operating in an environment conducive for carburetor icing at a glide and cruise power setting.
