Attention to detail. Fly the airplane no matter what. Let’s be careful out there.

Thank you for linking the report, I am sorry for your loss.

For what it’s worth, I recommend religious use of torque seal (visible paste that dries hard to indicate if a nut has moved) on all torqued parts including fuel/oil lines. Anytime final torque is made, apply a squirt of paste across the gap between the nut and the connector, and assume that any nut/connector without torque-seal has not been tightened yet. This even applies to routinely removed connections like oil lines for an oil change. Old hard paste is easy enough to chip off with a fingernail when a connector is removed, and fresh paste applied once reconnected.
