2024年11月12日，波音WTT会议介绍了一种新的改版处置办法，可供参考，整体意思是将盖板GASKET的所有漏油路径用胶封堵，然后使用金属胶带加固。处置后提供2FC的放行。
- Defuel aircraft per operator’s standard practice (Reference 737NG AMM 12-11-00)
- Accomplish a General Visual Inspection at the fuel leak location around the entire circumference of the access panel. Look for missing of pulled fasteners, cracks, corrosion.
- Using best available practice, solvent clean subject access panel clamp ring gaps using MEK per SOPM 20-30-03 in preparation for sealing application.
- Apply BMS5-45 Class B-1/2 sealant to the clamp ring gaps, ensuring the sealant is flush within the gaps around the full inner and outer circumference of the clamp ring. See Figure 1
- Locally clean lower skin surface and access panel surface using MEKper SOPM 20-30-03 in preparation for speed tape application.
- Apply speed tape (3M 425 or similar) over the subject access panel. See Figure 2 for typical tape application
- Refuel the main and center fuel tanks to the maximum fuel quantity for each fuel tank that can be used per operator’s standard practice (Reference 737NG AMM 12-11-00). Monitor the subject areafor 15 minutes to ensureleak free condition.
- If no leaks, restore aircraft fuel quantity for operators flight requirements. Otherwise, panel replacement is required.
- Ensure pilots are notified of the temporary repair.
- Before and after each subsequent flight, perform a General Visual Inspection of speed tape application integrity and to ensure the speed tape is still fully sealing the leak. Repair or reinforce tape as required.
- Replace the subject access panel at completion of 2 Flight Cycles..
If Operator uses the above repair please report back to Boeing the results of the repairand/or repair procedural recommendations.
2024年12月更新，参考该方法执行快速封堵有效，大约工时1个小时。建议优先使用。
