In a quick B-52 X-ray inspection, the inspection saved 17 days and strengthened confidence in the 70-year-old bomber.
In late June 2025, the US Air Force 412th test wing sharing Its Non-Destructive Inspection Team (NDI) team has completed a full 17 days of major inspections of the B-52 Stratoortress. This milestone marks the in-depth X-ray inspection of the B-52 at Edwards Air Force Base in nearly two decades. The fast turnaround not only allowed the iconic bomber to recover faster than planned, but also gave a glimpse of how modern diagnostic tools and agile processes operated life using platforms like the B-52.
According to the official version, the inspection is mainly focused on the flap tracks of the aircraft. These components can be under great pressure during flight, and any hidden structural defects can seriously affect safety and performance. Through digital X-ray technology and simplified logistics, the Edwards NDI team was able to complete the assessment before the 35-day window initially assigned by the Aircraft Maintenance Department (AMU).
To learn more about the significance of this work, Aeronautician Get more background. Here is the response from Mary Kozaitis chief to our exclusive Q&A on Edwards AFB’s NDI team, Media Operations 412th Test Wing / USAF OL Plant 42.
Q: What NDI techniques or tools are used (e.g., staged array ultrasound, digital X-rays), and how do they compare to traditional inspection methods?
Use digital X-rays. By performing digital X-rays, we reduced processing time by 60% and eliminated the need for dangerous waste of about 50 gallons. In addition, this movie can be used up to 500 times compared to traditional movies. Finally, since these files are stored digitally, we don’t have to use up space in the facility by storing hard copy film on the shelf.
Q: This article mentions that the inspection is completed 17 days in advance: How long does it usually take to check? How often do these checks usually be used for B-52?
The aircraft maintenance unit was allocated 35 days to complete this task. The NDI team completed the market research and accelerated the procurement of certain consumables they didn't have on hand so they could start early. This is the first X-ray of the B-52 in 18 years at Edwards AFB. However, it is difficult to measure what a typical completion schedule is, as the team moves to digital movies rather than traditional movies, which saves a lot of days on duty. To illustrate this in detail, images that are considered acceptable require certain densities. Since this is calculated radiography, the team is able to control density and contrast, while traditional factors (such as time, energy, temperate zone, etc.) it will require reshooting. This will greatly extend the completion time.
Q: From a structural integrity perspective, how much life or increased confidence does a successful NDI provide for such an old body?
The main work is observation and reporting. Since the team did not find any cracks, it was confident that owning the unit could put it back into the flight service or perform other maintenance measures. If the team does find something, the owner unit takes the findings and performs actions based on the technical order or the engineer’s disposal.
Q: Are any serious defects or abnormalities found during the inspection? If so, how important are they and what corrective measures have been taken?
Thankfully, no one found out.
Q: What are the next steps after inspection (other repairs, surveillance or flight verification tests)?
Since they didn't find anything, they didn't follow up.
Q: How does this check align with the broader B-52 structural integrity program?
This inspection gives the AMU and pilots at least confidence that these flap tracks are available.
Q: Is this accelerated inspection model replicable at other bases, or is the functionality of Edwards and the 412th test wing unique?
Yes, it can be copied. However, a base with a B-52 only performs B-52 inspections. At Edwards, NDI Labs is responsible for understanding all platforms assigned to the 412th Test Wing (many)! This is important because these NDI inspectors must be up to date and master each body.
Q: Can you provide some details about other types of NDIS?
On the 412th test wing, the team regularly performed phase checks composed of ultrasound, vortex and X-rays on the T-38. We also conducted various inspections on the F-16 phase. F-35 and F-22 often ask for our help. If any other unit requests any miscellaneous inspections, we will respond accordingly. In the words of SSGT Brandon Tate, “There is never a dull moment on Edwards NDI.”
As no serious defects were found and flight preparations were restored, the B-52 participating in this accelerated inspection had a mission again. This result demonstrates the lifespan and adaptability of the class. As we recently reportedThe plane marks the 73rd anniversary of its first flight earlier this year and is expected to continue using the B-52J, thanks to major upgrades in its engines, radar, avionics and crew configuration. Buff (the big ugly guy) continues to prove that this is not only a relic of the Cold War, but also a pillar of modernization for remote strikes and strategic deterrence.
