Over the next few weeks we will discuss the Rusada approach to performing heavy maintenance checks and how our new Envision Check management module will address some of these key challenges.
Performing a major heavy maintenance check represents one of the main operating costs of any airline and is a daunting task at the best of times. As a major MRO provider performing checks that can run from as short a duration as a few days to major re-configuration checks that can take months, the pressures to remain competitive is enormous. How do we perform these heavy maintenance tasks at the lowest cost possible? Can we still maintain the highest level of service and offer competitive delivery times and without compromising quality and safety?
This is the key challenge to any MRO provider.
Controlling the complexity of the check, especially with the amount of non-routine tasks that are raised as part of the check is no simple matter. With major checks, where the number of task cards can run into thousands, how do we efficiently manage the scope and detail of this check so as to ensure that all key requirements are available at the correct time and in the correct place?
How do we track the status of the check to a level where management have the key information relating to how the check is progressing?
How do we really know when the check will be finished?
What is the critical path of this major check?
Normally we think of our key requirements for a check as available resources, material and tooling. In reality, this is only the start of the problem. In managing a major check, not only do we need to consider the availability of these traditional resources but we also need to consider a range of additional requirements such as:-
- Availability of the correct version of all OEM documentation including online access to this documentation
- Waiting for customer sign-off of non-routine task cards
- Waiting for internal signoff of engineering tasks
- Availability of Ground Support Equipment
- Availability of OEM parts vs PMA parts
- Managing the interaction between scheduled and un-scheduled tasks
Over the next few weeks we will discuss the Rusada approach to performing heavy maintenance checks and how our new Envision Check management module will address some of these key challenges. In particular, we will focus on:-
1. To what level to I manage the project?
- If we plan down to each individual task card level this will require significant work for our planners
- If we plan at too high a level, we will never know the true status of the check
2. How do I control all of the costs and maximise what I can bill and invoice the customer?
3. How do I plan for the unknown amount of Non Routine work?
4. How do I allocated my resource between my routine and non-routine tasks?
- If I allocate too many to my routine tasks, that phase of the project might be completed early buy what is the impact on all of the Non routine work?
- If I allocate too many to my Non routine tasks, they will be closed off in time but what will be the impact on my routine tasks?
5. How do we allocated resources to our tasks?
- Do we roster our resources to individual tasks or phases of the check
- Do we let our resources select which task they want to work on each shift based on their trade and the status of the check?
6. How do we provide end user tools for the update of check progress?
- Mobile computing?
- Electronic Sign off?
7. What are my “What-if” analysis tools that might allow me simulate changes that I might want to make?
