Agusta Finds AB139 Tailpipe Problem
Agusta has found the cause of the problem that sparked an emergency Airworthiness Directive on the AB139 in August. The company said only that it is working to “minimize the inconvenience to customers.” The FAA had issued an emergency airworthiness directive on Agusta AB139 tailpipes. Reports of cracks have raised concern at the FAA and its European counterpart, the EASA, that such conditions could result in cowling overheating. This could start a fire, which in turn could cause separation of a part or a tailpipe assembly. In the worst case, this could destroy the tail rotor, causing a loss of control. The AD required inspections before further flights and thereafter at 25-hour intervals.
