Because Owning And Flying Your Beechcraft Can Be Done Safely AND For Less Money!
  Quick Release Seat Pins



So, because you're an "owner-assisted" annual kind of person, each year at annual you pull your seats out to allow inspection of the landing gear transmission and operating mechanism. Sometimes you might even pull the rear seats out.


If you're like me, one of the biggest pains is removing the little bolt and nut (some of the older airframes were equipped this way) that hold the seat stops against the seat rails.



In later years Beech is reported to have used "Quick Release Pins" in this area instead of the bolt and nut, making things quite a bit easier and quicker to remove and replace the seat stops.


Yeah, I know what you're thinking, it's still a PITA back breaker to get the seats aligned on the rails and slid back into position. But at least with quick release pins your back will be saved a little for the task of sliding the seats back onto the rails.


The Beech PN for the quick release pins they use is: BLNC3-11 @ $10.50 on 7/16/2011


The Beech PN for the machined Seat Stop is: 58-530231-1 @ $19.50 on 7/16/2011
