  Fixing a Limp Beechcraft Door Stop Rod




Does your door prop rod on your Beechcraft cabin door sit limp and saggy in the door sill of the airframe? If so, here is a narrative from Beech Lister and B2OSH guru Larry G. for removing your door rod and fitting a new bushing to the end that is in the airframe.


Fixing a "limp" Bonanza cabin door stop-rod:


Do this inside a hangar or when there is no chance a gust of wind is going grab your door while you work.


1. Open cabin door


2. Use mirror to look at underside of door. You will see that the stop-rod rides in a slot. There is a wide opening (a hole) in that slot.


3. Open (or close) door far enough that the door end of the stop-rod at the hole in the slot.


4. Pull down on the stop-rod. You will have to jiggle the door a little, but the stop-rod will come out of the door. Your door will swing freely, with nothing to stop it from going WAY past fully open. Open it far enough to get it out your way, but not all the way. Just short of parallel with the wing leading edge. Stuff a rolled up towel between the wing and the underside of the door to secure it.


5. The stop-rod will pull straight up and out of the door sill. It's deteriorated rubber bushing *should* come out with the chrome stop-rod. If it doesn't:



6. Use a needle nose pliers (or whatever it takes) to remove the bushing from the hole in the door sill. If the bushing is in pieces in the hole, dig or vacuum it out. I do not know the correct dimensions for the new bushing, but it's a piece of rubber hose. Fuel line or vacuum line. Figure it out thusly:


a. Using a micrometer, measure the diameter of the part of the stop-rod that sticks into the bushing and door sill. This is the inside diameter of the hose you want.


b. Also using a micrometer, measure the diameter of the hole in the door sill. This is the outside diameter of the hose.


c. The length of the part of the stop-rod that sticks into the door sill is the length to cut the hose. I think it's about 4", maybe longer.


7. Test fit the new bushing in the door sill. You might have to trim it a little in length for the door to open & close without interference. To reinstall, reverse the removal instructions.


a. Slip the bushing on the part of the rod that goes in the sill. A dab of DC4 on the rod is the perfect lubricant for this.


b. Stick the "assembly" into the sill.


c. Using the mirror, fit the door end of the rod into the opening in the slot in the underside of the door.


d. Open & close the door a few times to make sure nothing binds or rubs, etc.


Yer dun.


IA & Bonanza owner Bob B. adds:


"The original rubber insert has a thin metal sleeve. REUSE it or the fix will be questionable in short time. Also -4 303 hose. It will be tight. I taper it slightly to insert. The later rods are threaded for 1/4" nut. This works much better than the early rods with nothing to keep them from sliding up at the jam and down in the door."


When you open the door, the "springiness" of the rubber bushing will "push up" on the rod and it will "click" into place when the door is fully open. Gently step or push down on the rod to get it out of the "door open" detent to allow closing of the door.



Debonair owner, Leldon L., contributed the pictures for this narrative and reports that for his 35-C33 the approximate hose size needs to be 3/8" ID, 5/8" OD and 2.75" in length


I will add that to add some tension and resistance for the door stop to lock in it's slot, simply bend the rod upwards while it is out of the airframe pocket or while you have it out. This will put more tension on the rod pushing up and you will need a positive downward force with your hand or foot to bend it away from the locked slot position for closing the door.


Thanks for contributing to a great narrative Larry & Leldon!




If you're totally fed up with your factory door rod, here is an STC'd gas piston door opener to consider from Mtn View Aviation called The Door Steward:



The kit for the Beech lists for $210 and a mention of ABS will get the purchaser a 5% discount.  Ground shipping to anywhere in the lower 48 states is $10.  The kits come complete with all the parts and hardware needed for the installation, very complete installation and maintenance instructions, illustrated parts listing, sample FAA Form 337 filled out and a 2 year warranty on the parts.


Here is what one looks like installed on a Beechcraft door:




Elegant, IMHO!


Here is another Door Steward install




Here is yet another Door Steward install



Installation time for the kit is estimated at 4 hours for a first time installer, but a shop or mechanic that has installed one before can likely trim that install time down to about 2 hours.
