Kenny Keller walks through how a missed step during hydraulic checks caused a $35,000 overspeed incident on a Robinson R-44. The pilot increased throttle with the collective stuck, not realizing hydraulics had been turned off and never turned back on. Always visually verify hydraulics are re-enabled after maintenance.
So go ahead and stow this away. We'll do our hydraulic check. Friction coming off up here. The hydraulics are on. Should feel smooth. Hydraulics come off. Should feel stiff. Hydraulics back on. Confirming they are on.
Part of the reason there that cost us $35,000 overspeed because the guy went off, didn't turn it back on. Then he couldn't figure out why the collector wouldn't come up. And. And then while we were trying to figure out what was going on, he rolled the throttle on, did an overspeed because the collective wouldn't come up. Instead of trying to figure it out, he started rolling throttle when the collective wouldn't come up.
And you talk about that. And that's why now from hearing from that mistake. And you talk about your video. That's why now always just visually and verify that the hydraulics are back on.
