# 747 Service Bulletin **ALERT Summary**  **Number: 747-53A2852** Original Issue: June 22, 2012 ATA System: 5321

**SUBJECT:**FUSELAGE - Auxiliary Structure - Main and Upper Deck Floor - Upper Deck Floor Beam Upper Chord and Strap Replacement

THIS BULLETIN IS SENT TO THE OPERATORS OF RECORD OF THE AIRPLANES SHOWN IN PARAGRAPH 1.A., EFFECTIVITY. IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OWNER.

**CONCURRENT REQUIREMENTS**

None.

**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 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.
