The FAA is proposing a new airworthiness directive (AD) for certain models of Safran Helicopter Engines. This AD is in response to reports of non-conforming fuel filter pre-blockage pressure switches, which might not activate correctly if there's fuel contamination, potentially leading to engine shutdowns during flight. The proposed rules include routine visual inspections and operational tests of these pressure switches, and replacing them if necessary, to ensure that the engines remain safe to operate. Comments on the proposal are invited by April 8, 2021.
Simple Explanation
The FAA is making a new rule to check and possibly fix a part in certain helicopter engines so they don't stop working in the air. This rule wants people to look at and test the part regularly to make sure everything is safe.
