NTSB narrative
According to the flight instructor, during the takeoff roll, he noted that the airplane felt "sluggish." After checking all systems, he and the student pilot continued the takeoff. The flight instructor noted that, after climbing to 200 ft, the airspeed began to decrease while the engine continued to produce power. The flight instructor performed an emergency landing in a wooded area, which resulted in substantial damage to the wings and fuselage. An examination of the airplane revealed that the carburetor throttle linkage was striking against the exhaust shield, which prevented the carburetor throttle linkage from its full movement at full throttle. A review of the maintenance logbooks revealed that a new exhaust system was recently installed on the engine. It is likely that maintenance personnel failed to ensure that the throttle linkage was properly adjusted, which prevented the throttle from opening fully and resulted in the engine being unable to produce full static power.
Probable cause
Maintenance personnel's failure to ensure the proper throttle linkage travel clearance after the installation of an exhaust system.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
