This could be your chance to affect the rewrite of an important engine certification rule! The FAA has asked the Aviation Rulemaking Advisory Committee (ARAC) to look into engine endurance testing pursuant to 14 C.F.R. 33.87.
An engine endurance test is an accelerated severity test intended to demonstrate a minimum level of engine operability and durability within the approved engine ratings and operating limitations. The test running conditions cover the declared engine rating and operating limitations, but are not intended to precisely simulate the expected in-service operation.
The FAA has found that applicants need to modify their engines in order to meet the testing requirements of section 33.87, but that these modified engines are no longer accurate representations of the type design. Thus, there is a worry that modern engine technology has progressed to the point where section 33.87 no longer meets its intended function.
Dorina Mihail of the FAA Engine and Propeller Directorate is looking for engine technical experts to serve on the working group examining this rule. The FAA must receive all requests by February 11, 2014, so if you are interested in having MARPA promote your application to the working group. then please contact us before then.
