News of October 28, 2012 About Cessna 172’s refitted with diesel engines.
DieselAir is in the process of investigating the world fleet of Cessna 172's which were retrofitted with a Thielert or Centurion/Thielert diesel. These can be 1.7 or 2.0 liters, powers being 135 and 155HP. A constant speed propeller always was supplied with the conversion. We remind you that virtually all conversions were made before Thielert's financial difficulties which led the firm to be put under judiciary administration; that thanks to this disposition (equivalent to a Chapter 11 in the US) the engine manufacturer never interrupted business, has succeeded to sell and service their engines while offering and recommending parts replacements and preventive maintenance programs, and has sold engines as OEM equipment to at least 2 aircraft manufacturers. Also, you probably remember that Cessna intended to sell a variant of their ubiquitous plane with a Thielert as original equipment in 2008, aiming at the export market, and immediately discontinued this attempt due to Thielert’s financial difficulties. To our best knowledge quite a few 172’s were converted in Europe (most), in the US (a few), and at least in South Africa; also we understood that some 172’s converted before the supplier went through Chapter 11 were refitted or updated with Centurion’s supplies since. We did not receive any negative information about converted 172’s since Thielert has been under new management. We will welcome information from you if you own a Cessna 172 diesel; if you know who owns and operates such planes; if you occasionally rent one; if you have been working as a mechanics or other on such planes; and of course if your firm is active in such retrofitting’s today. |
