lack of some consumable material wa

lack of some consumable material was discovered in the middle of the check. It had to be additionally ordered on a higher priority level and was consequently more expensive.

In the re-installation phase of the project a few man-hours were lost due to the waiting for the material. The particular material could not be released from the store due to certificate issues.

Due to the aircraft flight hours flight cycles and in advance known job cards (inspections) of the project, some spare material was ordered in advance the basis of the previous experiences and expectations, but later on it was not used during the project.

On the last day, the aircraft departure was delayed for a few additional hours because of the uncompleted work orders, which could easily be closed one day before the end of the project.

4. Corrective Actions

Generally, improvements and other changes are always implemented during regular processes, therefore they must be performed or implement rapidly to prevent delays case of any interruption during the improvement implementation, the possibility for quick reaction in a sense of final solution implementation has to be available. It should be taken into account that process improvements always involve high level of unpredictability [15]. Frequently, the additional research, cooperation with external suppliers, customers, authorities and other approvals are required.

Figure 2 shows that the most time consumable NVAA portions of the project are:

Preparation phase

Close-up phase

Finding part of the Defect rectification phase

Therefore, the biggest impact on the project working hours and costs saving in combination with elimination of unnecessary project events can be found in the above mentioned three phases. Various suggestions on the basis the of questionnaire were checked. Below, the most promising are listed

Preparation phase:

Due to in advance known type of inspections and consequently in advance known requests for access panels and passenger seats removal, aircraft should be positioned closer to the composite and cabin work-shops, where the panels and passenger seats are inspected and repaired. The optimum position would be in Hangar 2. Hangar 1 should be used for other types of checks. The estimation of the time saved for access panels and passenger seats removal is more than 13%. This is quite a huge number, but taking into account that all the passenger seats, all the cabin interior panels, all the floor panels, galleys and toilets are closer to the composite and cabin work-shop, the number becomes more reasonable. This action reduces MUDA of Transportation and Muda of Motion. In Figure 5 better aircraft location regarding check type is shown.

Due to the simultaneous start of more projects on the same day (although unplanned) the lack of manpower occurred in the preparation and inspection phases. At every sub-phase of the preparation phase some time savings can be gained with a proper planning of manpower. This action reduces MUDA of Waiting

By starting the loan period on the day, when the tooling is required, loan costs of the tooling can be reduced. This action reduces MUDA of Over Production

Close-up phase :

Similar as in preparation phase, MUDA of Transportation and MUDA of Motion can be reduced due to a better position of the aircraft in hangar

Component's certificate issue extended installation time of the particular component for 2 hours. By settled certificates 2 hours or 6,7% of the installation time of the particular component could be gained. This action eliminates MUDA of Waiting and MUDA of Correction.

Duly closed work-orders reduce time in the Close-up phase. This action eliminates MUDA of Waiting.
