Directed Safety Investigation - Use of Higher Leaded Fuels in Engines Originally Certificated for Use With Grade 80 Aviation Gasoline.
Abstract
A Directed Safety Investigation (DSI) was conducted to determine: (1) the extent of maintenance required as a result of using Grade 100LL or Grade 100 aviation gasoline in engines originally certificated for use with Grade 80 gasoline; and (2) the extent of availability of Grade 80 gasoline. The DSI shows: (1) that an increase in the maintenance of spark plugs and valves is required when the higher leaded fuels are used in the Avco Lycoming 0-320 and the Teledyne Continental Motors 0-200 engines which were certificated for use with Grade 80 gasoline; (2) that Grade 80 aviation gasoline is not available in many places in the United States; and (3) that even though Grade 80 is available in some areas not all the fuel suppliers dispense it.
