Agusta A109E brake system
I’ve owned an Agusta A109E for about 5 years and I’ve noted that the park brake system pressure bleeds off over time. That is, if you put on the handbrake when on the ground, the pressure bleeds off and there are no brakes at all.
As the aircraft is on wheels, I’m wondering if there have been incidents or accidents where the pressure has bled off and the aircraft has then rolled into something.
It seems amazing to me that the design should be this way. In fixed wing aircraft such as Citations and Caravans, the hand brake actuator actually closes the hydraulic lines and the pressure remains on.
I look forward to comments.
