EAA is imploring the FAA to reconsider an AD it says would be impossible to achieve and unnecessarily broad in scope. The agency is proposing action that would require replacing the rudders on almost 31,000 legacy high-wing Pipers. "EAA believes this AD is flawed in regulatory process, scope, and requirements," the organization said in its comments on the AD. "It is based on limited data, the required action is not possible in the timeframe required, the affected models list is vast, and the action required is excessive." EAA wants the FAA to rescind it in favor of a Special Airworthiness Bulletin and do more studies on whether it's needed at all.
