Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: CONDUCT AN AIRWORTHINESS DESIGN REVIEW OF THE ENGINES IN PIPER MODEL PA-28R-201T TURBO III CHEROKEE ARROW, PA-28RT-201T TURBO IV CHEROKEE ARROW, AND PA-28-201T TURBO DAKOTA AIRPLANES DIRECTED TOWARD INCIDENTS, ACCIDENTS, AND ENGINE SERVICE DIFFICULTIES WHICH APPEAR TO HAVE BEEN EXACERBATED BY TURBOCHARGING, E.G., THOSE INVOLVING BROKEN PISTON CONNECTING RODS, SEPARATED OR CRACKED CYLINDERS, BURNED OR BLOWN PISTONS, ETC. IF INDICATED, REQUIRE THE INSTALLATION OF DEVICES TO ALLEVIATE THESE OCCURENCES SUCH AS COMPRESSOR DISCHARGE TEMPERATURES GAUGES, OIL INTERCOOLERS, PRESSURIZED MAGNETOS, COWL FLAPS, ETC.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to perform an airworthiness design review of the engines in Piper Model PA-28R-201T, PA-28RT-201T, and PA-28-201T airplanes, focusing on incidents, accidents, and service difficulties worsened by turbocharging, such as broken connecting rods or cracked cylinders. If the review indicates a need, the FAA should mandate installation of mitigation devices like compressor discharge temperature gauges or cowl flaps.
