Aerospace Filtration Systems (AFS) has received an STC from the European Aviation Safety Agency (EASA) for an inlet barrier filter (IBF) system for MD Helicopters’ MD900/MD902 Explorer series. IBF-equipped helicopters can operate with no engine inlet-imposed flight or weight restrictions. According to the company, corporate, air medical, law enforcement and fire/utility operators
have installed the system, which features dual long-life conformal filter assemblies readily mounted on the existing inlets.
Inlet bypass capability is achieved using the existing MDHI bypass system that is part of the inlet particle separator modification. Conformal inlet covers are standard with the system for added protection when parked. The new IBF system is also available as a factory-direct option on the MD900/MD902 Explorer.
