Service Bulletin

Number: 737-53-1260 Summary

Date: May 07, 2007

ATA System: 5321

SUBJECT: FUSELAGE - Passenger Cabin Floors - Station 520 to 540 - Seat Track Link 

Assemblies - Replacement/Modification

BOEING RECOMMENDS THAT EACH OPERATOR EXAMINE THIS SERVICE BULLETIN IMMEDIATELY.

CONCURRENT REQUIREMENTS

Group 1-2, 4-5: You cannot make the changes given in this service bulletin unless the changes given in Boeing 

Service Bulletin 737-53-1120 R01 are made. Boeing Service Bulletin 737-53-1120 R01 describes procedures 

to install a new channel with a seat track link assembly. 

Group 3: None.

BACKGROUND

This service bulletin gives instructions to repair or replace the cabin floor seat track link assemblies between BS 

520 and BS 540. If the work given in this service bulletin is not accomplished, the current seat track crowns and 

seat track link assemblies could separate during a 9G emergency landing condition. If the seat track crown and 

the seat track link assembly separate, the passenger seats would not have adequate support during a 9G 

emergency landing. This could result in injury to passengers. This condition does not comply with FAR/JAR 

25.561 emergency landing conditions, 9G forward loading.

Testing of a portion of the seat track revealed the structural deficiency related to the seat track crown attachment 

to the seat track link assembly. 

The changes shown in this service bulletin will restore the 9G forward loading condition in the areas between 

BS 520 and BS 540. 

 Boeing Service Related Problem (SRP) 737-SRP-53-0179 is related to this service bulletin.

ACTION

Group 1-4: Get access to seat track link assemblies at body station (BS) 520-540. At each location, replace the 

existing seat track link assembly with a new one piece seat track link assembly. 

Group 5: Get access to seat track link assemblies at body station (BS) 520-540. At each location, do a fastener 

modification to the existing seat track link assembly and intercostal.

BOEING SERVICE BULLETIN 737-53-1260

2. Spares Affected

None.

B. Concurrent Requirements

Group 1-2, 4-5: You cannot make the changes given in this service bulletin unless the changes given 

in Boeing Service Bulletin 737-53-1120 R01 are made. Boeing Service Bulletin 737-53-1120 R01 

describes procedures to install a new channel with a seat track link assembly. 

Group 3: None.

C. Reason

This service bulletin gives instructions to repair or replace the cabin floor seat track link assemblies 

between BS 520 and BS 540. If the work given in this service bulletin is not accomplished, the current 

seat track crowns and seat track link assemblies could separate during a 9G emergency landing 

condition. If the seat track crown and the seat track link assembly separate, the passenger seats 

would not have adequate support during a 9G emergency landing. This could result in injury to 

passengers. This condition does not comply with FAR/JAR 25.561 emergency landing conditions, 9G 

forward loading.

Testing of a portion of the seat track revealed the structural deficiency related to the seat track crown 

attachment to the seat track link assembly. 

The changes shown in this service bulletin will restore the 9G forward loading condition in the areas 

between BS 520 and BS 540. 

 Boeing Service Related Problem (SRP) 737-SRP-53-0179 is related to this service bulletin.

D. Description

Group 1-4: Get access to seat track link assemblies at body station (BS) 520-540. At each location, 

replace the existing seat track link assembly with a new one piece seat track link assembly.

Group 5: Get access to seat track link assemblies at body station (BS) 520-540. At each location, do 

a fastener modification to the existing seat track link assembly and intercostal.

E. Compliance

The Federal Aviation Administration (FAA) will possibly release an Airworthiness Directive related to 

this service bulletin. The Airworthiness Directive will make the compliance tasks and times given in 

this service bulletin mandatory.

Group 1: Do the seat track link assembly replacement as given Paragraph 3.B.1.a. within 60 months 

of the date on this service bulletin.

Group 2-3: Do the seat track link assembly replacement as given Paragraph 3.B.2.a. within 60 months 

of the date on this service bulletin.

Group 4: Do the seat track link assembly replacement as given Paragraph 3.B.3.a. within 60 months 

of the date on this service bulletin.

Group 5: Do the existing seat track link assembly fastener modification as given in Paragraph 3.B.4.a. 

within 60 months of the date on this service bulletin.

F. Approval

This service bulletin was examined by the Federal Aviation Administration (FAA). The changes 

specified in this service bulletin comply with the applicable regulations and are FAA approved, as well 

as European Aviation Safety Agency (EASA)/Joint Aviation Authorities (JAA) approved for all EASA/

JAA approved airplanes listed in the service bulletin effectivity. This service bulletin and its approval 

were based on the airplane in its original Boeing delivery configuration or as modified by other 

approved Boeing changes.

For airplanes and the rework identified in this service bulletin, initial release, the rework has been 

reviewed as required by paragraph (g) of Airworthiness Directive (AD) 98-11-04 R1. The rework is 

found to not create a Structurally Significant Item (SSI) or affect an existing SSI in Supplemental 

Structural Inspection Document (SSID), D6-37089. Therefore, no additional action is required to 

comply with AD 98-11-04 R1 with the rework of this service bulletin accomplished.

If an airplane has a non-Boeing modification or repair that affects a component or system also affected 

by this service bulletin, the operator is responsible for obtaining appropriate regulatory agency 

approval before incorporating this service bulletin.

G. Manpower

The table below shows an estimate of the task hours necessary to do the modification for each Group 

of airplanes. This estimate is for direct labor only, done by an experienced crew. Adjust the estimate 

with operator task hour data if necessary. The estimate does not include lost time. These are some 

examples of lost time:

— Time to adjust to the workplace

— Time to schedule the work

— Time to inspect the work

— Time to cure the materials

— Time to make the parts

(a) Align the seat track link assembly with the section 43 seat track crown using MIT002A0018-1 locating jig.

(b) Locate by aligning with bolt and bushing shown in steps 4 and 5.

(c) Do a detailed inspection. Check the position of the bushing straps. Make sure the bushing straps are 

mating flushed against the side of the seat track link assembly. If bushing straps are not mating flushed 

against the side of seat track link assembly, the seat track link assembly is not aligned with existing beam 

structures at Sta 537.45. The flanged bushing on bushing strap needs to be reworked to realign the seat track 

link assembly.

(d) Install bushing in existing seat track link assembly support channel at Sta 520 floor beam, 4 locations. 

Install bushing with BMS5-95 sealant as given SOPM 20-50-03. Do not apply sealant to bushing bore hole.

(e) Do a detailed inspection. Make sure the seat track link assembly is vertically aligned with the existing seat 

track. The vertical alignment should be within + or - 0.020 inch to make sure correct seat installation.

(f) Do a detailed inspection. Make sure that there is a minimum horizontal clearance of 0.17 inch between the 

seat track link assembly end and the section 43 seat track end.

(g) This step is not required if the gap is within the tolerance as given for minimum clearance.

(h) Make a mark on the section 43 seat track end where material needs to be removed.

(i) Cut and remove material from the section 43 seat track end.

(j) Do a detailed inspection. Make sure that there is a minimum horizontal clearance of 0.20 inch between the 

edge of the pivot bolt and the edge of the support channel.

(k) Make a mark on the support channel where material needs to be removed. The maximum distance that 

the cut edge can be made from the original edge of the support channel is 0.20 inch.

(l) Cut and remove material from the support channel.

(m) Do a detailed inspection. Make sure that there is a minimum horizontal clearance of 0.20 inch between 

the edge of the seat track link assembly and the fastener heads installed on the channel radius filler.

(n) If there is an existing floor beam repair at Sta 520 beam. Cut and remove a maximum of 0.40 inch and 

0.70 inch of material from the forward upper side flanges of the seat track link assembly. See section view 

C-C existing floor beam repair. This trim is required to provide clearance between the floor beam repair radius 

strap and seat track link assembly.

(o) Make a mark on the seat track link assembly where material needs to be removed.The maximum distance 

that the cut edge can be made from the original edge of the seat track link assembly is 0.10 inch.

(p) Cut and remove material from the seat track link assembly.

(q) Apply one coat of chemical conversion coating to all bare metal surfaces. Refer to SOPM 20-43-03 as an 

accepted procedure.

(r) Apply two coats of primer to bare metal surface. Refer to SOPM 20-41-02 as an accepted procedure.

(s) Match drill holes through the bushing straps into the seat track link assembly. Drill holes 0.247 - 0.250 for 

the bolt.

(t) See fastener code table below. Install the collar on the outer side of seat track link assembly.

(u) As given in 737 Structural Repair Manual, Chapter 51 for torque limits.

(v) Refer to SOPM 20-50-02 as an accepted procedure.
