Buyer Beware On AutoFuel STC'd Aircraft
April 19 , 2007 — Several recent instances have come to light where aircraft sellers have attempted to pass their aircraft off as having an autofuel supplementary type certificate (STC). Subsequent records checks with the two STC holders (EAA and Peterson Aviation) did not confirm this, and there were no placards on the aircraft. There have also been more ramp checks for autofuel STC documents at airports recently.
EAA and Peterson are the only organizations that issue these placards since the program began in the early 1980s. If you are buying an aircraft that has been advertised or you were verbally told that the aircraft has an autofuel STC, and that is a factor in determining your final purchase decision, check to make sure the aircraft does indeed have the STC.
Contact Petersen Aviation through the AutoFuel STC Website or you can email Debi Walker at EAA or call 920-426-4843 to see if the records are on file. Also, check to see if the aircraft has placards on the wings next to the fuel inlets. If there are no placards, it?s possible that someone fraudulently used a copy of an STC or has misrepresented the aircraft to a potential buyer.
The autofuel STC today costs a minimum $1.50 per horsepower of the engine. A complete set of standard documents can include an information packet, possibly with Field Information, Instructions, an Authorization Page, Airplane Flight Manual Supplement (required to stay in the aircraft), Instructions for Continued Airworthiness, STC for the airframe, and STC for the engine. There are also Service Bulletins and other information that are sometimes included with the placards in the packets.
An autofuel STC can save you a lot of money over the years and can add to the value of your aircraft when you want to sell.
