When it comes to military aviation parts, you’re probably looking at an old military aircraft

The most expensive pieces of military aircraft you’ll find at thrift shops are likely from World War II.

But now, thanks to a recent lawsuit, you can purchase parts made by a different military organization.

The Civil Air Patrol (CAP) sued the military to prevent its parts from being used in new Boeing 737 aircrafts.

According to the lawsuit, the parts were used in the F-35 Joint Strike Fighter program and are now part of a range of military fighter aircraft used by the U.S. Air Force, Navy, Marines and Coast Guard.

According the lawsuit:The F-16 Fighting Falcon, the F/A-18E/F Super Hornet, the A-10 Thunderbolt II, the E-3 Sentry and the AIM-120D Counter Attack Missile all received military parts from the U-2 spy plane.

The lawsuit also alleges that in order to comply with the FAA, the military used parts from other U.N. peacekeeping and military aircraft and sold the military parts to a variety of American companies.

It also alleges the military also sold the parts to U.K.-based military suppliers including Northrop Grumman and Pratt & Whitney.

But CAP says the parts are not part of the UF-18 and cannot be used in Boeing’s new jets.

The complaint also alleges, among other things, that the parts could be used for other military aircraft in the future, and that the military’s “disposition of the materials was a violation of [its] obligations under [the] Arms Export Control Act.”

A spokesperson for Boeing told Mashable in a statement, “We are pleased to be partnering with the CAP to ensure our customers’ rights are protected.”CAP claims the lawsuit “will cause significant harm to Boeing and the U of T community, and will adversely affect our ability to compete for future contracts.”

“The suit is the latest in a long line of efforts to bring legal action against Boeing, the UTS, and the Canadian Government over alleged violations of export controls,” the spokesperson said.

In a statement to Mashable, Boeing said it would defend itself against the lawsuit.

“We stand ready to defend ourselves in the courts of law,” the statement said.
