Materials status control. a. Routine materials status b. Non-routine/ADD materials status c. Modification /repair kit or special tooling required if any. d. Off wing OCCM or major components repair /OVH T.A.T or redelivery schedule. 1 of 26 Pekamco Technologies Pekamco.com

  6. A320 family heavy maintenance project management GTA (contract) review a. The fixed price and cap of non-routine labor, consumable materials, expendable and peculiar materials ( BFE etc) b. Obligations of both parties understood; Attention to responsibility of materials purchase , special tooling loan and T.A.T. c. Attention to how well the aircraft is leasing - which will impact the PMA parts usage or reimbursement requirement. It is very important issue for customers. Aircraft basic information a. share and provide airplane technical data and information, such as type of oil, fluid, MTOW, BFE data etc. Review the C check flow chart. ( It applicable for MRO PM or on-site rep) a. Milestone set up. I b. initial inspection phase and due date. Important for entire schedule. c. Repair/ mod due date and re-installation start d. Power on/hydraulic on/weighting/engine run/test flight 1 of 26 Pekamco Technologies Pekamco.com

  7. A320 family heavy maintenance project management 2. Pre-inspection for aircraft condition ( Preliminary check) If applicable. Depends on operators or MRO experience, mainly focuses on structure and cabin issues. Improves the layover quality and avoids significant structural damage, the pre-inspection is necessary. Obtain accurate part numbers and quantities to order peculiar materials. Consider the layover increase risk Order necessary materials/tooling if structural damage is found. The pre-inspection is not applicable for every C check. It is better for 6Y or 12 Y check or cabin refurbishment. 1 of 26 Pekamco Technologies Pekamco.com

  8. A320 family heavy maintenance project management 3. Communication and Liaison preceding C check C check working schedule discussion and correction with Planning or MRO ( It applicable for MRO project Manager and on-site rep as well). Account for layover information such as materials, tooling, T.A.T etc. Very important for MRO PM or Airline On-site rep. Technically, it is the final opportunity to brief the project before aircraft are incoming. If Airline on-site rep, you may pay careful attention to the following: a. Minimum fuel quantity and outstation fuel agency handling. b. Contact MRO for first working day arrangement c. Update airlines Non-routine and ADD status and inform MRO. 1 of 26 Pekamco Technologies Pekamco.com

  9. A320 family heavy maintenance project management 4. Aircraft input to the C check Phase 01----Aircraft incoming a. Share technical information with project team in first daily meeting b. Acquire the working schedule and emphasize key points ( Milestone or potential points) c. Fix both parties materials resource coordinator agenda and communication paths. Phase 02 ---- Removal and Access a. Based on the work package analysis , trace the process and focus on the key working zone ( Fwd, Aft galley aisle floor beam, top skin, rear spar, floor pan of LAV. Floor beam under cargo ball mat etc. ) Note: Important! Based on your knowledge and experience, you may catch key points and push our MRO to follow them in its priorities. b. Key working zone inspection without removal/access. - Such as both wing top skin, rear spar , T/R surface or wiremash corrsoion and de-lamination. 1 of 26 Pekamco Technologies Pekamco.com

  10. A320 family heavy maintenance project management Phase 03----- Inspection a. Continue following and monitoring key area working processes. Request report on daily basis. b. in case of any outstanding finding, especially for structures, immediately work with team for measurement, report, and liaison with vendor. Moreover, attention to whether the entire schedule will be impacted. c. Attention to materials request. Note: Important! Have to review item by item. First of all, you may know if the missing materials are critical or not, next to verify the leading time will match the schedule. d. We will Work closely with your QC and Materials resource to identify the critical missing parts, leading time, delivery date, any re-installation impact etc. 1 of 26 Pekamco Technologies Pekamco.com

  11. A320 family heavy maintenance project management e. Meanwhile, both parties should consider two solutions for missing materials, one way is to order anew, one way is to repair. It is better for time and cost savings. Moreover, the schedule will not be impacted due to missing materials. Phase 04 and 05----- Repair/modification/non-routine handling a. Attention to the major repair /modification process and to avoid any impact for final hydraulic on and power on. b. Pay more attention to the interface between major modification or repairs. It always happens in ageing aircraft’s heavy maintenance. Major repair interface may change the jacking CG or affect jacking procedure. Note: Important! Jacking loan need 5 days at least from HAM airbus. It represents potential risk for T.A.T 1 of 26 Pekamco Technologies Pekamco.com

  12. A320 family heavy maintenance project management c. Set up the deadline for materials delivery and feedback materials status with your team. Note: Technically, the mass of missing materials requests will be reported from production after the inspection phase is done. - Especially for China mainland MRO’s. The phase 04/05 is a good opportunity to follow and trace the missing materials. Phase 06----- Reinstallation and Non-routine handling a. Push the materials availiability and fulfill the milestone. Note: Delayed materials cause cost waste. b. Attention and monitoring key non-routine task processing, it will impact reinstallation schedule. 1 of 26 Pekamco Technologies Pekamco.com

  13. A320 family heavy maintenance project management Phase 07----functional test and final assembly a. Fulfill the power on and hydraulic on. b. Technical logic for final test sequence. - Especially for aircraft LDG swing, weighting, fuel on-board check, engine run. Note: At C check final phase, you need to with an MRO PM for key issues, not only consideration for materials supply. Final working flow also needs be discussed and reviewed. If applicable, the key workflow will be enhanced. Phase 08----- close up and redelivery a. If on-site rep for airlines, inform flight operation of delivery date and request for ferry flight schedule in advance. b. Ask flight dispatch for ballasting and fuel quantity. c. make a cross index for incoming non-routine and inform MCC in advanced. d. Make a ADD records and extention records , inform MCC and planning department in advance if applicable. 1 of 26 Pekamco Technologies Pekamco.com

  15. A320 family heavy maintenance project management 1.A320 family both wing top skin corrosion Inspection and findings must be as earlier as possible. 1) No extra access required for such inspection zone, the inspection must be done once aircraft is incoming. 2) If in case finding, polish and blend out will be followed and measured. The step shall be finished at first day. 3) If corrosion is out of limits, a structural engineer needs to be involved immediately, make a grid for the damage area, and report to AIRBUS promptly. 1 of 26 Pekamco Technologies Pekamco.com

  16. A320 family heavy maintenance project management Note: Long delays will be incurred If the top skin corrosion cannot not be found at first phase. Major impacts as following: a. damage report and AIRBUS inquiry. b. oversized fasteners seeking and order c. special jacking procedure and jacks loan if reinforce plate required. In summary, the top skin corrosion is a major issue leading to long delay. Early inspection/report and fasteners estimate/ordering are important. If advice is followed, the entire repair T.A.T can be deducted 5 days at least. 1 of 26 Pekamco Technologies Pekamco.com

  17. A320 family heavy maintenance project management 2.A320 family rib 5 inspection and modification This is AD requirement for each AIRBUS aircraft. For ageing aircraft, it is a potential risk for aircraft redelivery a. Inspection must be first priority once LDG removed. b. Bore inspection and blend out must be careful. If crack found, structural engineer must be involved immediately and report to AIRBUS. c. Special tooling and reamer need be loaned from AIRBUS. Some airlines also need AIRBUS on-site advisor to support. Note: reamer goes in slowly and controls size carefully to ensure the crack is eliminated and the bore inner diameter is within limit. d. If crack remains and the bore’s inner diameter is out of limit, the fitting must be replaced by AIRBUS working party. Entire repair T.A.T is 14 days. 1 of 26 Pekamco Technologies Pekamco.com

  18. A320 family heavy maintenance project management 3.A320 family SB A320-57-1154 and A320-57-1155 inspection and Modification. This is recommended for each aircraft , especially ageing aircraft. a. special NDT tooling must be prepared before C check layover. b. modification kits must be available before C check. c. No more extra access inspection area, the inspection has to be performed once aircraft is incoming. d. If found, the concerned area damage limits need to be verified immediately. If out of limit, oversized fasteners need be estimated and ordered. Meanwhile, structural engineers need to be involved and report to AIRBUS. Note: If above findings happened, you may coordinate with MRO to readjust the schedule. Because Top skin repair and Two SBs repair Will be seriously interfered. 1 of 26 Pekamco Technologies Pekamco.com

  19. A320 family heavy maintenance project management 4.A320 family lavatory floor pan heavy corrosion in the lavatory wet zone The floor pan heavy corrosion will incur extra removal or access and impact cabin restoration process. a. If floor pan leading time is long it will impact entire T.A.T. b. If corrosion or crack heavy, the underlying floor beam will incur corrosion. The extra removal and access is required. 1 of 26 Pekamco Technologies Pekamco.com

  20. A320 family heavy maintenance project management Highlight C: A320 aircraft heavy maintenance cost saving and re- adjustment of T.A.T. 1 of 26 Pekamco Technologies Pekamco.com

  21. A320 family heavy maintenance project management 1.Detailed analysis of the GTA details, such as the cap of Non-routine manhour, materials, and obligation of both parties. Attention to the cap of Non-routine manhour definitions, It is better to discuss the above charges in the final phase. Only if you carefully review the routine task card and understand the contract may you know the non-routine resource and how much labor you should pay for. Attention to the cap of materials price and routine task cards involved zone or area, you may know how much materials cost need to be paid. Attention to the obligation of both parties, you may know the key obligations such as tooling loans, warranty, redelivery etc. 1 of 26 Pekamco Technologies Pekamco.com

  22. A320 family heavy maintenance project management 2.Deeply understand and analyze the work package, such as customized MP tasks and major work scope. Attention to the major access and major routine task cards, such as LDG,ENG,THS removal, Cargo loading removal, cabin floor panel etc, you may clearly figure out the work sequence and milestones. Attention for preliminary check, especially for structure inspection and CPCP tasks ( MRB5,8 or CMR) , you may estimate the potential risk and easily trace the key points. Attention for Off-wing ( OCCM or hard time control) components requirement, one way you can follow the materials status, another way you will find close or open loop repair T.A.T. Attention to routine task cards working zone, you may know how much the above charge would be incurred. 1 of 26 Pekamco Technologies Pekamco.com

  23. A320 family heavy maintenance project management 3.Combine work schedule processing, make materials delivery a priority and closely monitor milestones of the entire project. Whatever C check duration, you have to give attention to the materials delivery time and schedule. It can save operator cost directly and can save the layover time. Attention to the schedule process, provides enough stress to MRO and controls the non-routine materials raise. Based on your knowledge and experience, you may focus on the key missing materials who will impact entire project milestones. If any key missing materials cannot match the milestone, you may consider moving the schedule sequence and try to fulfill the final delivery target or reduce delay time. For example, If top skin are fasteners missing, you need to move the final phase tasks forward to avoid time waste. 1 of 26 Pekamco Technologies Pekamco.com

  24. A320 family heavy maintenance project management 4. Negotiate the final labor of non-routine and additional work requests. You have to have figure out or estimate what non-routine or additional tasks will occur above charge. The handling process and result needs to be closely monitored. Finally you will catch up the key point and negotiate with MRO. 1 of 26 Pekamco Technologies Pekamco.com

  25. A320 family heavy maintenance project management 5.In case outstanding issues will impact delivery targets, the schedule sequence and milestone could be movable and match the final target. It depend on your experience and knowledge. If outstanding issue occurred, you may clearly figure out what’s major work zone or task will be postponed. What tasks can be moveable or adjusted. The time need must be carefully reviewed and estimated. In this phase , task combination is first priority. 1 of 26 Pekamco Technologies Pekamco.com

  26. A320 family heavy maintenance project management Technically, this is general instruction for AIRBUS A320 family common C check. This instruction is a little bit different with leasing aircraft delivery or redelivery check. Major requirement will be as followed: 1) Work package analysis and estimate 2) Materials status confirmation and follow up 3) Enough stress for MRO and control key milestone 4) Any schedule arrangement or adjustment will fulfill final redelivery target. 1 of 26 Pekamco Technologies Pekamco.com
