Commercial Airplanes 777 Service Bulletin ALERT SummaryNumber: 777-52A0038Original Issue: June 18, 2009 Revision 1: June 24, 2010 ATA System: 5234 SUBJECT: DOORS - Forward Large Cargo Door - Lower Sill Latch Pin Fitting (LPF) No. 1 through 8 - Latch Pin Retention Bolt Inspection

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 Accomplishment of this service bulletin will inspect the forward large cargo door lower sill Latch Pin Fitting (LPF) No. 1 through 8 at Station 509.10, 522.75, 537.50, 554.30, 562.90, 579.70, 591.25 and 604.90 for loose, fractured or missing latch pin retention bolts. A fractured retention bolt can become separated from the LPF and latch pin, which could lead to migration of the latch pin. A latch pin that migrates and becomes disengaged from the main cam latch can result in increased loads on adjacent LPFs, which may cause damage to the cargo door latch mechanism and/or lower sill structure. The migration of two or more latch pins can result in the inability of the cargo door to carry limit loads which may cause loss of the cargo door and catastrophic depressurization of the airplane.
The forward large cargo door LPFs are attached to the door lower sill and numbered 1 through 8 forward to aft.
LPFs and latch pins are an integral component of the large forward cargo door latching mechanism that carry structural and pressurization loads during flight.
Two operators have reported missing and fractured LPF latch pin retention bolts. One report indicated that on a 777-200 airplane at LPF No. 1 and 2, Stations 509.10 and 522.75, one retention bolt was found on the ground during closure of the forward cargo door and after further inspection a second bolt was noticed to be missing from the adjacent fitting. In addition it was found that one of the latch pins had migrated away from engagement with the corresponding cargo door main cam latch. Based on this report, Boeing requested a limited survey of the 777 fleet for missing and/or fractured latch pin retention bolts. In response to this request an operator reported that after applying a 15 in-lb test torque to all eight retention bolts on a 777-300, one retention bolt fractured at LPF No. 2, Station 522.75. In both cases no further damage was reported as a result of the missing and fractured retention bolts. All bolts were replaced and the airplanes were returned to normal service.
Boeing has developed terminating action for the Latch Pin Fitting (LPF) latch pin retention bolt inspection and replacement that was given in the original issue of this service bulletin. In addition, repeat LPF latch pin retention bolt inspections are added to this revision as optional action for terminating action.

Boeing Service Related Problem (SRP) 777-SRP-52-0090 is related to this service bulletin.
ACTION (PRR 62777-68S)
INSPECTION Do a Detailed Inspection and torque check of the forward large cargo door lower sill Latch Pin Fitting (LPF) No.
1 through 8 at Station 509.10, 522.75, 537.50, 554.30, 562.90, 579.70, 591.25 and 604.90 for loose, fractured and/or missing latch pin retention bolts.
If no retention bolts are fractured or missing do terminating action, or alternatively, change the installed bolt head direction of existing bolts if necessary or if bolt head direction is unchanged apply a torque to check for loose bolts. If no retention bolt is found loose, do repeat Detailed Inspections and torque check for loose bolts.
If any retention bolt is found loose, apply the specified full torque. If any bolt is found fractured during the initial inspection and has not separated from the LPF and latch pin, carefully remove the bolt and do a Detailed Inspection of the LPF latch pin retention bolt hole for cracks and/or surface depressions. If no cracks and/or surface depressions are found do terminating action, or alternatively, install a new retention bolt (same type as the removed bolt or Inconel bolt.) Do repeat Detailed Inspections and torque check for loose bolts. If any crack and/or surface depression is found in the LPF, more work is required as specified.
If any retention bolt is missing and the associated latch pin has not migrated more than a specified distance, do a Detailed Inspection of the LPF latch pin retention bolt hole for cracks and/or surface depressions. If no cracks and/or surface depressions are found, do terminating action, or alternatively, install a new retention bolt (same type as the removed bolt or Inconel bolt.) Do repeat Detailed Inspections and torque check for loose bolts. If any crack and/or surface depression is found in the LPF, more work is required as specified.
If any retention bolt is missing and the associated latch pin has migrated more than a specified distance, do a Detailed Inspection of the forward large cargo door lower sill, fuselage frames and internal/external skin, cargo door frames and main cam latch mechanism for damage. If any damage is found remove the associated LPF and repair the fuselage and/or cargo door in accordance with applicable 777 Structural Repair Manual (SRM) or contact Boeing for repair data and do the repair. Then do a Detailed Inspection of the LPF latch pin retention bolt hole for cracks and/or surface depressions. If no cracks and/or surface depressions are found do terminating action, or alternatively, install a new retention bolt (same type as the missing bolt or Inconel bolt.) Do repeat Detailed Inspections and torque check for loose bolts. If any crack and/or surface depression is found in the LPF, more work is required as specified.
TERMINATING ACTION Terminating action is not complete until titanium bolts have been removed and replaced with new Inconel bolts at all LPF No. 1 through 8 locations.
To accomplish terminating action, do a Detailed Inspection of LPF No. 1 through 8 for fractured or missing latch pin retention bolts. If no retention bolts are fractured or missing, remove the existing titanium bolts and replace with new Inconel bolts. No further action is required. If any existing retention bolt is found fractured and has not separated from the LPF and latch pin, carefully remove the bolt and do a Detailed Inspection of the LPF latch pin retention bolt hole for cracks and/or surface depressions. If no cracks and/or surface depressions are found, replace with a new Inconel bolt. If any crack and/or surface depression is found in the LPF, more work is required as specified.
If any existing retention bolt is missing and the associated latch pin has not migrated more than a specified distance, do a Detailed Inspection of the LPF latch pin retention bolt hole for cracks and/or surface depressions.
If no cracks and/or surface depressions are found, replace with a new Inconel bolt. If any crack and/or surface depression is found in the LPF, more work is required as specified.
