EASA has issued an Airworthiness Directive (AD) for Arriel 1E2 engines. Cases were reported of finding ruptured front support pins on Arriel 1E2 engines. The ruptured pins were detected either during accomplishment of a maintenance task or during inspection prompted by abnormal vibrations in flight.

The FAA's Engine Certification Office intends to write an Immediately Adopted Rule in response to this EASA AD. The justification is because of the very frequent inspection intervals that are mandated and the possibility that at least some engines in the United States have already exceeded 2,400 hours or will do so shortly.
