400 Chinooks pinned to the ground because of a bad part: US Army


(NewsNation) – The US military has confirmed to NewsNation that the reason it grounded an entire fleet of Chinook helicopters earlier this week was because incorrect parts were installed in some of the planes.

As NewsNation previously reported, 400 Chinook cargo helicopters were grounded, the military said Wednesday, after fuel leaks caused a “small number” of engine fires. No injuries or deaths were reported, the army said.

Army officials said they grounded the helicopters out of “an excess of caution”.

This all happened after a piece of engine equipment was replaced with the wrong part during maintenance, according to the military.

The part “received an incorrect part number and was subsequently installed on certain Chinook helicopters,” the military said in a statement. “This error has been corrected.”

The Wall Street Journal reported that the part, called an O-ring, is suspected of causing seven fuel leaks, four of which resulted in engine fires.

The military has relied on the Chinooks for nearly 60 years. They can carry up to 36 troops and cargo loads, and are also used in search and rescue missions and in airdrops.

On Saturday, the helicopters were still grounded. NewsNation has no timeline from the military on when the plane will be back in action.

A private sector engineer familiar with the Chinooks previously told NewsNation’s “Rush Hour” on Wednesday that he hoped the military would fix the problem soon.

“With their features and capabilities, I think everyone is on deck at this point to get these things off the ground as quickly as possible,” said Rob Roedts, senior director of aerospace technology and manufacturing at Columbia Helicopters. .
