Lack of Spare Parts Is Keeping F-35s on the Ground
The logistics system designed to keep the F-35 fleet flying often
doesn't, with more than a fifth of grounded planes sitting idle waiting for
spare parts. The result is fewer airplanes available for training-and
increasingly, combat-as the system struggles to keep an ever-growing number of
jets flying.
Aviation Week & Space Technology reports that parts shortages and bureaucracy
are hampering efforts to keep the F-35 Joint Strike Fighter in the air. In
particular,it includes an anecdote
about an Air Force major whose helmet had a broken plastic clip, a problem that
would have grounded him for two weeks as he waited for a replacement. It was
only when the issue was escalated to the Joint Program Office, which runs the
F-35 program, that rules were bent to fix the problem.
The single anecdote speaks volumes about the F-35 program's logistics
system. The program is designed to centralize the repair and spare parts program
as much as possible, to increase efficiency and reduce costs. Instead of every
F-35 base stocking plastic clips, helmets, or even engines, a centralized,
global computer system would keep track of all working and spare F-35 parts
worldwide, sending them to bases worldwide in a timely manner as needed. Repairs
are done at a handful of depots to minimize costs and maximize
efficiency.
On paper that sounds like a great idea, no doubt inspired by the
just-in-time nature of companies such as Amazon and UPS. Together, the two
companies can ship millions of types of goods globally from a handful of
distribution centers, overnight on a consumer's whim, often for completely
trivial reasons. In practice, the F-35 program needs two weeks to ship a plastic
helmet clip to someone who needs it more urgently than the typical Amazon Prime
customers needs their latest impulse buy.
According to AW&ST, the parts shortage
is so severe that at Eglin Air Force Base, "maintainers are constantly battling
for parts." Twenty two percent of the F-35s grounded globally are unable to fly
because they are waiting on parts. The F-35's only forward-deployed until,
Marine Corps F-35Bs regularly based in Japan, has a readiness level just over
fifty percent. In October 2017, the average time to repair a part was 172 days,
twice the F-35 program's goal.
The story mirrors a General Accounting
Office report in 2017 but paints a more vivid picture. In 2017
the GAO in large part pinned the problem on the Air Force and Navy not providing
enough funding to build out six centralized repair depots with some needed
capabilities not coming online until 2022. Another problem: the F-35 program was
simply not buying enough spare parts.
The government, unlike Amazon, operates from a fairly fixed federal
budget, and experiences an inventory loss on every spare part used. Furthermore,
the F-35's logistics program, with its monopoly on providing to pilots, is
seemingly unconcerned with "customer service," versus enforcing bureaucratic
rules about switching plastic clips from helmet to helmet in the
field.
The services are trying to fix the situation, establishing an
"organic government repair capacity" and increasing the budget for spare parts.
Given the complexity of the F-35 and its subsystems, it's hard to see an
alternative to a centralized repairs and spare parts system. Still, it's clear
the new fighter's global logistics system still has a long way to go.
