BACKGROUND

This service bulletin gives instructions to replace the upper chords and reinforcing straps on the upper deck

floor beams. The upper deck floor beam upper chords have been determined to be structure that could develop

Widespread Fatigue Damage (WFD). WFD of the floor beam upper chords could reduce the structural integrity

of the floor beams such that multiple adjacent beams could become severed, resulting in rapid decompression

of the airplane.

Analysis by Boeing indicates that accomplishment of the inspections, repairs, and modifications currently in

Service Bulletin 747-53A2452 are not adequate to ensure the structural integrity of the affected upper deck floor

beam upper chords on airplanes that are operated beyond 30,000 total flight cycles. On these airplanes, Boeing

recommends that the upper deck floor beam upper chords and reinforcing straps be replaced in accordance

with this service bulletin.

For more information on WFD, refer to Boeing Service Letter 747-SL-53-088A.

This table is provided to operators for planning purposes only. Refer to the applicable sections for more

information.

BOEING SERVICE BULLETIN 747-53A2852

ALERT ALERT
C. Reason

This service bulletin gives instructions to replace the upper chords and reinforcing straps on the upper

deck floor beams. The upper deck floor beam upper chords have been determined to be structure that

could develop Widespread Fatigue Damage (WFD). WFD of the floor beam upper chords could reduce

the structural integrity of the floor beams such that multiple adjacent beams could become severed,

resulting in rapid decompression of the airplane.

Analysis by Boeing indicates that accomplishment of the inspections, repairs, and modifications currently

in Service Bulletin 747-53A2452 are not adequate to ensure the structural integrity of the affected upper

deck floor beam upper chords on airplanes that are operated beyond 30,000 total flight cycles. On

these airplanes, Boeing recommends that the upper deck floor beam upper chords and reinforcing

straps be replaced in accordance with this service bulletin.

For more information on WFD, refer to Boeing Service Letter 747-SL-53-088A.

D. Description

Get access to upper deck floor beams from the upper deck and main deck, as necessary. Remove the

floor beam upper chords and reinforcing straps. Do an open hole High Frequency Eddy Current (HFEC)

inspection at all accessed holes and repair any cracks that are found. Fabricate and install new upper

chords and reinforcing straps. Re-install any repairs or parts that are not replaced. Install all equipment

and panels removed for access.

Upper chord replacement is only required at "full length" upper deck floor beams aft of station (STA)

360 that span the entire width of the airplane from the left side of body frame to the right side of body

frame.

standards given in SRM Chapter 51, then a fastener of the same specification, or

an approved substitute, with a length which meets the installation standards given

in SRM Chapter 51 may be used. In addition, washers may be installed for fastener

grip length in accordance with SRM Chapter 51.

6. A Detailed Inspection is defined as: An intensive examination of a specific item,

installation, or assembly to detect damage, failure, or irregularity. Available lighting

is normally supplemented with a direct source of good lighting at an intensity deemed

appropriate. Inspection aids such as mirrors, magnifying lenses, etc. may be

necessary. Surface cleaning and elaborate procedures may be required.

9. Fasteners may be oversized 1/64 or 1/32 inch as needed. Maintain 1.7D edge margin

on the upper chord and all adjacent parts. At fasteners common to the floor beam

to frame connection, 1.5D minimum edge margin is acceptable in Section 41 with a

reduced after-modification inspection threshold as given in Paragraph 1.E.,

Compliance. Edge margin is defined as the distance from the edge of the part to the

center of the hole, and "D" is the hole diameter.

10. The instructions in Paragraph 3.B., Work Instructions and the figures can include

operation of tools or test equipment. Boeing Engineering Tool Drawings, the Illustrated

Tool and Equipment Manual, and the Special Tool and Ground Handling Drawing

Index contain data on versions of the tools or test equipment that you can use. It is

permitted to use replaced tools. It is not permitted to use superseded tools.

11. If it is necessary to remove more parts for access, you can remove those parts. If

you can get access without removing identified parts, it is not necessary to remove

all of the identified parts. Jacking and shoring limitations must be observed.

12. Where the work instructions include installation of a kept part, a new or serviceable

part with the same part number can be installed as an alternative to the kept part.

13. Boeing Service Letter 747-SL-51-048, Damage Reporting and Repair Plan/Design

Guidelines, is an acceptable procedure to request information from Boeing for

additional structural repair instructions. The Service Letter describes what information

must be provided to Boeing before a structural repair can be provided.

PART 3 - Upper Deck Floor Beam Upper Chord Fabrication and Installation

1. For each floor beam location where replacement is required as shown in the applicable FIGURE

1 or FIGURE 2 or FIGURE 3 or FIGURE 4, make a new upper chord and associated straps or

angles.

a. Fabricate a new upper chord and straps or angles. Refer to APPENDIX A for the applicable

parts and fabrication requirements. Use the existing parts as a guide and to match the profile

of the existing chord to frame attachment.

b. Apply one coat of Type 2, Class A chemical conversion coating to bare aluminum surfaces.

Refer to SOPM 20-43-03.

c. Apply two coats of BMS 10-11, Type 1 primer to the new parts. Refer to SOPM 20-41-02.

2. For each floor beam location where replacement is required as shown in the applicable FIGURE

1 or FIGURE 2 or FIGURE 3 or FIGURE 4, install a new upper chord, new associated reinforcing

straps or angles, and any kept or replaced parts in accordance with the applicable production

drawings (Refer to APPENDIX A). In Section 41, also refer to Service Bulletin 747-53-2272 as

necessary.

NOTE: Fastener holes may be oversized up to 1/32 inch to correct damage or misalignment. If

more than 1/32 inch oversize is necessary, contact Boeing. At rivet locations where the

hole was already oversized during accomplishment of Service Bulletin 747-53-2272, do

not further oversize the hole, and install the same diameter rivet as was called out for SB

747-53-2272. At bolt locations where the hole was already oversized during

accomplishment of Service Bulletin 747-53-2272, make the hole an additional 1/64 inch

oversize and install oversize fastener. If further oversizing is necessary to meet hole

quality requirements, contact Boeing for instructions.

NOTE: Make sure a minimum edge margin of 1.7D is maintained in both floor beam and body

frame. At fasteners common to the floor beam to frame connection, 1.5D minimum edge

margin is acceptable in Section 41 with a reduced after-modification inspection threshold

as given in Paragraph 1.E., Compliance.

NOTE: Install bolts common to the upper chord wet using BMS 5-95 sealant. Refer to SOPM

20-50-19.

3. After upper chord replacement is complete, reapply BMS 3-23, Type II, Class 2 Corrosion Inhibiting

Compound (CIC) to the new upper chord structure and fasteners.

PART 4 - After Replacement Inspections

1. At the time given in Paragraph 1.E., Compliance, of this service bulletin, do inspections as follows:

a. Do open hole HFEC inspection at the floor panel attachment holes and surface HFEC

inspection at the permanent fastener locations for cracks in the replaced upper deck floor

beam chords, in accordance with Service Bulletin 747-53A2452.

b. Do HFEC inspections of the upper deck floor beam upper chords at strap/frame connections
