Background

    Several diesel engine models were certified in the United States 
and Europe before World War II. However, the development of higher 
performance spark-ignition engines fueled by leaded aviation gasoline 
(AVGAS) during that conflict resulted in a suspension of further 
development of these engines. Interest in diesel aircraft engines has

[[Page 54095]]

recently been renewed in response to the demand for engines that do not 
require leaded fuel for operation. Many new issues develop as modern 
diesel engine technology is integrated into these aircraft engines. 
This policy does not create any new requirements.

    Authority: 49 U.S.C. 106(g), 40113, 44701-44702, 44704.

    Dated: Issued in Burlington, Massachusetts, on September 6, 
2007.
