Analysis

The acft was a Cessna 172 that had been converted to a 'Texas taildragger' in accordance with an approved STC. The purpose of the flt was for the plt to obtain a biennial flt review. He stated that immediately after takeoff, the eng began to progressively lose power, with exception of 2 or 3 short power surges. The instructor plt (CFI) said that he turned on the boost pump & varied the mixture control with no positive results. He stated that the eng never completely lost power. The CFI assumed control of the acft & made an emergency landing by maneuvering between houses & obstructions. However, during the landing, the acft struck a power line, a fence & a ditch. An exam of the eng & acft revealed no major discrepancies that would have resulted in a loss of power. The density alt was about 6800 ft.
