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 for inspection, repair, and replacement of the upper deck tension ties on stretched upper deck (SUD) airplanes that have been converted to Boeing Special Freighter (SF) or Boeing Converted Freighter (BCF). Severed or disconnected tension ties at multiple locations could result in rapid decompression and loss of structural integrity.
This service bulletin is for station locations from 880 to 1100 where floor beams were replaced with tension ties during conversion to SF or BCF. Tension ties have been determined to be structure that is susceptible to Widespread Fatigue Damage (WFD). WFD could cause multiple adjacent tension ties to become severed or disconnected from the frames. For more information about WFD, refer to Boeing Service Letter 747-SL-53-088.
Accomplishment of the inspection and replacement actions in this service bulletin will ensure that tension tie cracks are detected, and that cracked tension ties are repaired or replaced before they become severed.
Service Bulletin 747-53A2507 and 747-53A2559 are for inspection, repair, and modification of tension tie and frame structure at station locations from 1120 to 1220 where tension ties were installed in production on the same airplanes.

For airplanes that have been converted by Boeing to SF or BCF configuration, do the following actions:
INSPECTIONS:
– Get access to the tension tie structure from station 880 to station 1100. Do initial and repetitive detailed inspections for cracks in the tension tie structure at each station location. For a longer repeat inspection interval, also do HFEC inspection for cracks in the forward and aft tension tie channels around the fasteners.
If any cracks are found, get access to the frame structure at stations where tension ties were found cracked and do a detailed inspection of the frame structure between stringer 3 and stringer 12 on both sides of the airplane. Repair or replace any cracked structure.
REPLACEMENT:
– At each station from 880 to 1100, remove and discard the existing tension tie channels. Also, remove and discard the existing straps and fillers at the outboard ends of the tension tie where the tension tie attaches to the frame. Do HFEC inspection of all open holes in the frame structure where the tension tie was removed.
If a crack is found in a frame, contact Boeing for repair instructions and do the repair. Install new tension tie channels, straps, and fillers. Before installation of permanent fasteners at the outboard ends of the tension ties, cold work the fastener holes common to the frames and straps.
POST-REPLACEMENT INSPECTIONS:
– After replacement, restart initial and repetitive detailed (or detailed and HFEC) inspections beginning at the post-replacement inspection threshold in accordance with this service bulletin.
EFFECTIVITY 747-100B SUD, 747-200B, 747-300, 747-400, and 747-400D airplanes. Refer to Paragraph 1.A., Effectivity, for the list of affected airplanes.
