'Reason was largely unknown. There was an SB on the older windscreens where they had to be inspected for cracks around the rivet holes. This one had been inspected with no anomaly’s found. It’s always part of my preflight when I clean it as well. The US Importer for Aeroprakt , Andy, who I know and respect greatly reached out Saturday evening after the event and mentioned he was going to be in contact with the factory on Monday, which he did. Aeroprakt made the SB a mandatory replacement to a thicker upgraded windscreen on Monday after our incident. Hopefully the SB being a mandatory replacement will save a life."
