- What it does
The FAA is adopting a new airworthiness directive (AD) for all BRP-Rotax GmbH & Co KG (BRP-Rotax) Model 915 iSc2 C24, 915 iSc3 C24, 916 iSc2 A, 916 iSc2 C24, 916 iSc3 A, and 916 iSc3 C24 engines. This AD was prompted by a report of oil leakage from cracks in the wall of the turbocharger valve housing due to insufficient thickness. This AD requires replacement of the turbocharger valve housing and reidentification of the turbocharger. The FAA is issuing this AD to address the unsafe condition on these products.
