1. SHELL MODEL APPLICATION ANALYSIS DURING THE MAINTENANCE WORK CAPTAIN : ZAY YAR AUNG MYANMAR AIR FORCE ISG (54) 16.1.2020

2. Contents Abstract Purpose SHELL Model Describing Interface of SHELL Mode SHELL Model Application Analysis in Aviation Maintenance Conclusion

3. Abstract As technology is changing. The safety culture of aircraft maintenance. What is Human factors? HF is about people. One of the most popular model : SHELL MODEL !

4. SHELL Model is a conceptual tool. Originated by Edwards in 1972 (SHEL) Hawkins developed in 1975 Another Liveware into original concept. (SHEL SHELL)

5. Purpose To know about some HF . To apply in our maintenance work . Safety analysis and training tool .

6. SHELL Model Describing S H L E L

7. = R ules , instructions, policies , safety procedures , SOP = V arious equipment, tools, aircraft , buildings and other physical resources = Working environment; hanger, noise, temperature, lighting = (Individual); strength, knowledge, mental and emotional well-being = (Group); teamwork, amount and quality of communication S H E L L

8. Interface of SHELL Model Software – Liveware Hardware – Liveware Environment – Liveware Liveware - Liveware

9. Software – Liveware Interface Misinterpretation of procedures B adly written manuals Poorly designed checklists S H L E L

10. Hardware – Liveware Interface N ot enough tools , I nappropriate equipment, P oor aircraft design for maintainability. S H L E L

11. Environment – Liveware Interface N oise , Workplace lighting, Climate and temperature S H L E L

12. Liveware – Liveware Interface Center Liveware (individual); knowledge , attitudes, cultures and stress Outer Liveware ( group); co-ordination , team work, communication , leadership S H L E L

13. An Analysis of the Incident I Experienced Local Made Heavy Maintenance Steps

14. Scratched Aircraft Body

15. Analysis with SHELL MODEL N o specific procedure or instruction N ot manufactured by OEM, not compatible for maintainability N ot enough of proper maintenance GSE facilities H uman factor, fun and over-active nature P oor S oftware + weakness H ardware + unsafe condition of E nvironment + unsafe acts of L iveware = incident/accident

16. Implement with SHELL MODEL R elevant maintenance manual ( be clear, easy to read, easy to understand, easy to do) P roper resources are available ( order and stock anticipated parts ) E stablish a safe and comfortable work environment ( reduce noise, adequate lighting, environmental controls, required facilities) H igh level of co-ordination and teamwork ( knowledge and skill to communicate effectively)

17. Conclusion G ood operating procedures (as simple as possible, easy to understand, easy to do ) G ood educated training (relevant on-type; aircraft/equipment /tools) G ood environment (convenience for working) G ood co-ordination and teamwork (3Cs : be Correct, be Complete, be Clear)

18. To add some facts A ccording to the SHELL model ( must good-match the central L) R esponsibility on both (maintenance person and organization) H ealth and fitness ( to perform our jobs effectively and safely) T o avoid maintenance errors in aviation ( follow regulations, organization provide facilities and training; HF, MMS, SMS) Not only above these , up-to-date our knowledge and fitness for our health
