**2026 archive** · May 14, 2026Reporting prepared October 22, 2026\. This retrospective describes events and expectations from the period covered.[Browse the archive](https://pvweekly.com/archive/)

Nearly three-quarters of aircraft completing Air Force depot maintenance in fiscal 2024 missed their original target dates, according to a Government Accountability Office report released May 14, 2026\. The share had been 31 percent in fiscal 2019.

The service’s main performance measure told a less complete story. The Air Force tracked original and revised completion dates but primarily reported results against the revised ones. GAO found that targets were often changed after work was finished to match the actual completion time.

Unexpected repairs can justify changing a maintenance plan. They do not erase the time an operating unit spends waiting for its aircraft. Reporting both dates lets commanders distinguish an expanded job from a late return and see how much availability the change consumed.

A second GAO report, released July 31, supplied a concrete example aboard the B-52\. Maintainers found unexpected wing corrosion, then had to engineer repairs and obtain parts. Beginning in fiscal 2022, the corrosion added about 58 depot days on average.

In fiscal 2025, maintainers introduced extra inspections and prepared standard collections of spare parts. GAO reported that those steps reduced the additional time associated with the corrosion repairs. The response changed the job’s preparation, rather than simply moving its deadline.

Parts remained a wider problem for the aging bomber. Some original manufacturers had closed or stopped producing suitable components. Air Force officials told GAO that ordering and receiving a new part took at least two years, and could take longer when too few suppliers were interested.

The two reports cover different aircraft populations and earlier fiscal years; their findings cannot be combined into a single 2026 readiness rate. Read together, they identify two useful measures of improvement: a candid account of the original wait and evidence that recurring repairs can be completed faster.
