maintenance hours per flight hourmsci world ticker

The amount of money needed to keep cutting-edge military aircraft airborne once they enter service is also considerable.Here is another Chart that shows the cost of operating the US Air Force’s most expensive planes:The E-4 Nightwatch is the most expensive military plane the Air Force operates.

Is there something else that you can do to better understand and predict maintenance costs? Rather than using maintenance cost per flight hour, build your budget on predicted total maintenance costs, which should yield a more accurate estimate.For this scenario, let's assume that the information in Figure 1, maintenance costs per flight hour, is all that you have to work with. But cost-wise certain questions come to mind. Can you point out to the representative that in actuality, the average cost per year over the 11-year period is about 33 percent of the cost of the most recent year? The greatest resource available to the aviation commander is the time assigned soldier maintainers are actually turning wrenches on their aircraft. Generally, they are a conservative group and do not like surprises, especially surprises that cause a cash shortage. Here’s a sample of what it costs to keep these Air Force aircraft airborne for one hour last year (the so-called “ownership” cost-per-flight-hour, which includes modifications): A-10C Warthog Attack Plane — $17,716 And in total, over a long period of time, with a similar number of flight hours, perhaps the total cost will be similar. However, the increase in maintenance costs per flight hour is compounded if you experienced both a reduction in flight hours and an increase in maintenance costs in a given year. This is from an Australian Transport Safety Bureau paper written by Dr Alan Hobbs. The average maintenance cost per flight hour for the 11 years has been about $210 while the cost per year for the most recent year, as shown, was $625. This is a very likely situation in a year of heavy scheduled maintenance. Its costs are partially due to the lack of an efficient supply chain for the aircraft, something that should be sorted out over the coming years.
That must mean that the difference between the 10th year in Figure 1 ($625) and the same year in Figure 2 ($150) is attributed primarily to scheduled maintenance costs.As a result of breaking your costs down, what appeared to be a very large gap between the total maintenance costs and on-condition maintenance costs is not as intimidating.What is your response?
Ten percent may not seem significant but when total operating costs can be in the hundreds of thousands or millions of dollars, then even 10 percent becomes significant.If a cost category is significant, that alone will catch the attention of the executive management team. Figure 2 reveals that through the 10th year, this aircraft has averaged about $110 of on-condition maintenance costs per flight hour. Add to that, the expensive and significant nature of maintenance and you have a subject that attracts a great deal of attention. (On-condition represents those costs that are associated with items that get replaced due to their condition and are not based upon a schedule.) Modern military fighter aircraft are extremely expensive to procure with the unit cost for a single F-35A coming to $98 million.

If one inspection requires more time and parts to complete than another, then the cost should also be greater. maintenance man-hours per flight hour must not exceed 11.5 or a penalty will be imposed. This is a very significant point to make especially if it ensures longer-term employment.There is another factor to consider that would affect the maintenance cost per flight hour. A representative from your executive management team walks into your office.

My first reaction was sticker shock, while my second reaction was disbelief that perfectly good functioning parts would be either retired or overhauled and at a great deal of expense.Since maintenance costs do attract so much attention, do what you can to gain a better understanding of their significance and behavior. Maintenance costs will also vary according to aircraft type, i.e., a light jet vs. a medium vs. a long range. Surprisingly, the much-maligned F-35 is only the seventh most expensive plane per hour that the Air Force flies. Throw in the fact that you may be dealing with inexperienced executives in aviation and the subject of maintenance costs can become more difficult. The two go hand in hand. Its costs are partially due to the lack of an efficient supply chain for the aircraft, something that should be sorted out over the coming years. First of all realize that the representative has performed what has become one of the popular buzzwords in our industry. When do the differences occur? But as you are probably aware several factors can make the representative's comparison a bad one.You will probably want to clarify several points to make sure the comparison is valid. And that perhaps it's time to get rid of the aircraft or get out of aviation altogether.What is your response? But then that is a subject for another article.© 2020 Endeavor Business Media, LLC.
