The U.S. military has grounded its entire fleet of CH-47 Chinook helicopters due to a risk of an engine fire, U.S. officials said.
Army officials are aware of a small number of engine fires with the helicopters, and the incidents resulted in no injuries or deaths, US officials said. One of the officials said the fires occurred in recent days.
The U.S. Army Materiel Command grounded the fleet of hundreds of helicopters “out of an abundance of caution,” but officials were examining more than 70 planes containing a part suspected to be linked to the problem, officials said.
Grounding Chinook helicopters, a battlefield workhorse since the 1960s, could pose logistical challenges for U.S. soldiers, depending on the length of the order.
The grounding targeted certain Boeing Co. BA,
-models manufactured with engines manufactured by Honeywell International Inc. HON,
said people familiar with the matter. The grounding took effect within the past 24 hours or so, these people said. The military has around 400 helicopters in its fleet, one of the US officials said.
