So we’re happy about that. What we’ve got to give honorable mention, the 747, we’re still making spares of 747. Slide 26. This slide you’re familiar with, a couple of changes, though to it. GE Aviation Jet Engine Program sales history, I won’t go into the history, just look at the slide – in the column though, look at Q1 to Q2, $6.2 million to $3.1 million, there is a $3.1 million difference, and I think that’s about half, isn’t it? Yes. For Q3, we got $4 million booked, but we’re not – it’s not a forecast because there’s so much uncertainty, which we’ll talk about a little bit more. We get it, it’s a burn down, we got it in Q3 and Q4. So I mean, look, we wouldn’t expect to be less than that, but we’re not giving you that as a forecast.
We’re just saying this is what we know, and we’re not giving you a forecast. We just don’t feel comfortable. Now one thing I want to add is on the right hand – in a little box here, see, $9.4 million. Remember we said earlier, same amount of non-GE Aviation Programs in Q1 and Q2. So that annualized, it’s $37.5 million. And I just want to – just to remember that number, $37.5 million, if I forget when we get to our outlook. So we’ll talk about that again when we get to that outlook. I think on Slide – I don’t know, 35 or something like that. Okay. Let’s go to Slide 27. Okay. Now this is the painful part of the presentation. GE Aviation sales are all about the MRAS inventory burn down, still in time, the sharp drop-off in Q2 GE Aviation program sales is all about MRAS’s burn down of Park inventory carried by them and its subcontractors.
Now this is a really key point. The MRAS calendar year 2022 build plan, that’s their build plan, not our plan. They’re build plan. This is what they plan to build in 2023. We got to build plan too, I think, 2028 or 2029. This comes from them, not us. It translates into approximately $20 million – sorry, $23 million of calendar year 2023 Park Aviation GE Program sales. It’s very easy to do the math. Once we know how many units they’re going to build, we know how much material is used per unit, we know what we sell the material for. So it’s very easy to do that math to get to $23 million. That’s a pretty precise number, assuming the build plan is correct and normally it is, that’s approximately $5.75 million per quarter. So the MRAS calendar 2023 build plan is reduced to some extent, this is just a side point.
Because MRAS is carrying excess finished structures inventory as well. I was reluctant to put this in, this could be confusing. This is just saying, their build plan would be more, except they have their own inventory. That’s nothing to do with Park inventory. As far as Park’s concerned, what matters is their build plan, okay? That’s what matters. That says, this is how many units they’re going to build, and that will drive how much material – Park material they’re using. But since MRAS’ 2023 build plan translate to $5.75 million in Park GE Program sales per quarter. Why were Park GE Programs sales only $3.1 million in Q2? I guess we already kind of gave away the little secret, but what explains $2.65 million, that’s just math. That’s taking $5.75 million subtracting $3.1 million.
Which translates to $2.65 million gap to doing Park’s expected Q2 GE Program sales based upon the build plan and parts actual Q2 GE Program sales. Well, again, now it’s all about the burn down – the MRS burn down of Park’s inventory carried by MRAS as subcontractors. The inventory burn down explains 100% of the gap or short flow, which makes sense because – as we had the programs are ramping up, the programs are going strong. So why would the number be down? Well, that’s the explanation. That’s 100% of the explanation. Let’s go on to Slide 28. Why the inventory burn down? Why the surprise about the excess Park inventory being carried by MRAS? I’m going to say something, I mean, very sincerely, MRAS is a wonderful customer. The relationship between MRAS and Park is very special and unusual and Park is very fortunate to have such a wonderful customer as MRAS, and that’s such an unusual relationship with MRAS.
