Every now and then, late additions such as MODs, ADs or EOs, are added to the heavy maintenance program. If you are managing a 3, 5 or even 15 year plan, addressing those new requirements may result in potentially hundreds of visits and thousands of requirements within visits that need to be reconciled, one by one. One can imagine the level of manual work, frustration and human error that may ensue.

 Imagine the level of manual work, frustration and human error that may ensue

Let's imagine a new MOD campaign, such as adding WIFI across a fleet. Naturally, the planner must decide how best to plan each instance of the MOD. In doing so, they ask themselves a set of questions: Do I add the MOD into my heavy visits? If I do, what is the yield loss of extending a visit to include the MOD. Is it more efficient to plan the MODs as stand-alone visits? If I do, I will have to justify why it made more sense to take the aircraft out on a separate visit. Or should I look for visits containing work on the same area of the aircraft, and determine the efficiency gains in doing the MOD work then.? Finally, how do I ensure effective use of the limited resources we have to do the actual work? How do I phased-in the work so it doesn't fall due at the same time? Clearly a complex undertaking.

Another example: The escalation of a block check, such as a C check going from 5,000 to 6,000 cycles. On the surface, a seemingly trivial change to the program but it can, in fact, lead to loads of manual work and complexity for the planner. Fallout tasks such as ALI’s (Airworthiness Limitation Item) and SDI’s (Special Detailed Inspection) that cannot be escalated along with the check will need to find a (proper) home. And the same questions that surfaced for late addition MODS/ADs/EOs need to be asked for every single fallout task that needs to be re-planned.

With IFS Maintenix Fleet Planner, such disruptions can be handled with ease - without consuming days of your time and taking you away from strategic work. Late additions can be added to full or sections of the plan, while preserving the hard work you've already invested. The scheduling engine will simply combine or not combine visits in a way that seeks to maximize the utilization of maintenance resources and aircraft availability, while following organizational business rules. Different planning scenarios can also be modeled to account for planning possibilities of these late additions, and then be compared against a set of KPIs to pinpoint what is best for the business.
