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 shortly after departure the airplane’s engine lost power. The pilot selected a nearby field for a forced landing. An initial inspection of the airplane noted damage to the airplane’s wings and fuselage. Fuel was available in the airplane’s fuel tanks, and the engine had about 8 quarts of oil in it. After the airplane was recovered, a visual inspection of the engine did not reveal any pre-impact abnormities. A test run of the engine was subsequently conducted and the engine ran at various power settings and no anomalies were noted. An examination of the fuel system revealed no anomalies. Before and after the test run, data from an onboard engine monitor was downloaded. The data did not illustrate any abnormalities with either the cylinder head temperature or exhaust gas temperatures that were recorded; the total loss of power was evident. No abnormalities were noted during the engine test run and the engine appeared to make rated power. A reason for the loss of engine power could not be determined with the available information.

NTSB Probable Cause

The loss of engine power for reasons that could not be determined with the available information.

Full Narrative

On August 24, 2021, about 1030 central daylight time, a Beech A36 airplane, N67CW, was substantially damaged when it was involved in an accident near Granbury, Texas. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot reported to the responding Federal Aviation Administration (FAA) inspector that shortly after departure from the Pecan Plantation Airport (0TX1), the engine lost power. The pilot selected a nearby field for a forced landing. An inspection of the airplane by the FAA inspector noted damage to the airplane’s wings and fuselage. Fuel was available in the airplane’s fuel tanks and the fuel selector was positioned to the left tank. The engine had about 8 quarts of oil in it. (See figure 1) Figure 1: Accident airplane FAA photo During recovery of the airplane, about 80 gallons of fuel, split evenly between the fuel tanks, were recovered from the airplane. After the wreckage was recovered, an examination and test run were conducted. The fuselage, minus the wings, was strapped down to a trailer. The top engine cowling was removed, and a visual inspection of the engine did not reveal any pre-impact abnormalities. A fuel canister was connected to the airplane’s fuel line on the airplane’s left side. The engine started without hesitation or delay and was then warmed up at idle rpm. The throttle was advanced, and a magneto check was completed; no anomalies were noted. Full throttle was then applied, and the engine responded accordingly. Before and after the test run, data from the engine monitor was downloaded. The data did not illustrate any abnormalities with either the cylinder head temperature or exhaust gas temperatures that were recorded; the total loss of power was evident. The airplane’s fuel tanks, and main fuel strainer were checked for contaminates/blockage. No abnormalities were noted during the examination and engine test run and the engine appeared to make rated power.
