It's much more likely at take off, with the high deck angle of climb out. Ask me how I know.... When it happens, it happens quickly. I'm over 6 feet tall, and I fly with the seat only one click forward from fully back. I know about seat rail failures, and I know what to do when it happens. Still, when the rail gave way, and I scooted back the distance of only one click, I wasn't able to release the yoke fast enough to keep the stall horn from chirping. I was, by the way, about 500 AGL. Scary stuff. ________________________________ Message 14 ____________________________________ Time: 04:16:24 PM PST US From: Gary Vogt Subject: Re: TeamGrumman-List: Seat Track Hi Tom,=0A=0AThere are a few seats that are made wrong.

We have rebuilt quite a few of these with new tracks and solved the problem. I know all the AG's had the heat treated tracks but I'm not sure about the switchover point in Savannah. The alignment issue can occur for several reasons, one being a slightly bent spar bracket that allows the seat to sit slightly crooked in it's mount. I guess they get bent while the seat is out of the plane for servicing. Another issue we have seen it an "out of square" seat pan that was apparently dropped when out of the plane with enough force to warp it - maybe they ran over it with their tug. We have also found loose clevis bolts that allow the seat to twist on the bracket - this will also allow the tracks to be damaged as will missing spacers on the rear attach bolts. Our planes, after 30 plus years of great and not-so-great annuals with sometimes less-than-Grumman savvy mechanics display many non-standard and "creative" repairs - many that look quite scary. I would encourage you to make sure your seats are functioning as they should and make sure all hardware is properly installed and, as obvious as this sounds, are the right parts. If someone needs specific help, drop me a note and we'll figure it out.
