Airmotive Engineering Corp. v. FAA

The DC Circuit denied a petition for review of the FAA's "airworthiness directive," that mandated removal of some of petitioner's engine cylinder assemblies. The court held that the FAA's conclusion that AEC63 cylinder assemblies presented a "hazardous" risk in the event of failure was supported by substantial evidence in the record. The court explained that the FAA gathered the record evidence, over a period of years, with multiple rounds of public comment, on the safety risks posed by AEC63 cylinder assemblies, and the FAA's "unsafe condition" determination was based on a proper application of the FAA 8040.4A methodology and was supported by substantial evidence in the record on cylinder assembly failures.
