Reclining Chairs
Models D18S and D18C | No. 8 | Revised: July 15, 1954
MODIFICATION OF THE BEECH RECLINING CHAIR FOR REVERSE SEATING
If reverse seating is desired, it may be accomplished by making the following changes in the mechanism of Beech-manufactured chair shown in Figure 1 and Figure 2 included with this service letter. Catch assemblies as shown in Figure 1 will identify the Beech-manufactured chair.
If it is desired to relocate the chair to provide more leg room, the floor boards must be reinforced in the new location similar to that in the old location.
These instructions cover the Beech-manufactured chair only.
When the chair is reversed in its present location, it will not change the loading schedule.
1. Remove the chair to be modified from the airplane
2. Remove the cushion assemblies from the base of the chair by releasing the two catch covers and pushing straight back on the seat with stops depressed.
3. Disconnect the two cushion assemblies. (Provisions should be made to protect the upholstery.)
4. Remove the two catch assemblies marked “A” in Figure 1 and replace with modified assemblies provided in Equipment Kit No. 503.
5. It will be necessary to back drill the four mounting holes and the three edge spring holes. Use the present holes in the chair as a jig.
6. Remove the two cable assemblies and sheaves from both right and left fitting assemblies.
7. Install new sheaves on pinion and add cable guards to fitting assemblies as shown in Figure 2.
NOTE: Turn the pinion shaft 90 degrees before drilling new hole in shaft to accommodate longer sheave.
8. After step 7 has been accomplished, replace the present cable assemblies with the new lengthened cables provided in kit
9. Anchor new cables in the old location and wind six turns on sheave. Route cables in original position and connect to turnbuckle and adjust to desired tension.
10. Connect the two cushion assemblies and replace in the base of chair and fasten catch covers.
11. Replace the chair in the airplane in desired position in old location using present floor board fasteners.

The following procedure and diagrams will serve as a guide for reworking the floor boards when the chair is reversed and moved forward to provide additional leg room.
When reverse seating is desired and the chair is to be moved forward, it will be necessary to remove the floor boards from the airplane to accomplish this modification. It will also be necessary to revise the loading schedules.
1. Remove the chairs from the floorboards and remove the carpet.
2. Remove the floorboard to be modified from the airplane.
3. Remove the old fittings from the floorboards.
NOTE: Do not remove reinforcement strips that are glued to the floorboards. Plug old mounting holes with dowel pins provided in the kit.
4. Refer to figure 3 for information on cutouts in the floorboards to provide for installation of Wedjit assemblies.
NOTE: When making cutouts in floorboards for Wedjit assemblies, do not cut through the reinforcement strip
5. Reinforcing strips and metal plates for reinforcement in new locations are provided in the kit.
NOTE: Sand the surface of the floorboards where reinforcement is to be glued as shown in Figure 3.
6. After location of Wedjit assemblies have been determined according to Figure 3, turn one of the Wedjit assemblies over and use as a jig to mark cutout to be made in the linoleum, then using some sharp instrument make the eight cutouts in the linoleum only.
7. After the eight cuts have been made in the linoleum, place the wedjit assembly in the cutout and mark the location for the four mounting holes.
8. See Figure 3 for information on adding reinforcement to floorboards.
9. After reinforcement strip has been added, drill the four mounting holes through floorboards and reinforcement strip as shown in Figure 3 and install Wedjit assembly.
10. Holes through floorboard and reinforcement strip only, are to be drilled 1/4 (.250) inch to match 404-180243 spacers.
11. After the floorboards have been reworked and Wedjit assemblies added, replace floorboards in the airplane.
12. Replace the carpet and make cutouts for the chairs in new location.
13. Replace the chair in the airplane.
