FAA Emissions Proposal Has Some Operators Worried

A recently released FAA proposal would amend FAR Part 34 fuel venting and exhaust emission requirements for turbine-powered airplanes, proposing new, tighter emission standards for engines manufactured after Dec. 31, 2003. Engines that entered production before that date will be grandfathered and exempt from the new standards. The complex and confusing proposal has some operators concerned about the status of their powerplants and the cost of maintenance needed to achieve compliance, but the concern is unfounded because engine manufacturers are competing in a global environment. Dom Sepulveda, Pratt & Whitney Canada’s manager of environmental regulatory affairs and emissions, told AIN, “As necessary, the FAA amends certification standards for aircraft engine emissions (FAR Part 34) to be in compliance with international standards. Pratt & Whitney is aware of these international standards and has always developed engines with a global perspective. Therefore, this revision will have no impact on P&WC engines, and we will not have to retrofit any engines to be compliant.” Business aircraft engines made by other manufacturers after Dec. 31, 2003, are understood also to comply with the new requirements already.
