UPDATE:

FORT RUCKER, Ala (WDHN)— According to Jimmie Cummings, Public Affairs officer for Fort Rucker, the cause of the CH-47’s fleet engine fires has been found.

The Army has identified an incorrect manifold O-ring that caused fuel leaks as the source of the problem and is prioritizing the delivery of replacement parts.

“The Army has conducted an initial records review to identify suspect engines on aircraft and in
stocks, which have a high probability of having an improper manifold O-ring,” said Cummings “We are still in the process of inspecting all of our CH-47s here at Fort Rucker. These aircraft will be grounded until corrective maintenance is complete.”

FORT RUCKER, Ala (WDHN)—As of the last 24 hours, the U.S Army has grounded its entire fleet of Chinook helicopters due to the risk of engine fires.

According to U.S Army officials, they are aware of a small number of engine fires with the aircraft. The incidents did not result in any injuries or deaths.

The U.S Army Material Command grounded the fleet of around 400 Chinook helicopters “Out of an abundance of caution.”

Officials are looking at more than 70 aircraft that contains the part which could be causing the problem. Issues may be targeted at certain Boeing Co.-made models with engines manufactured by Honeywell International Inc., said officials dealing with the matter.

The grounding could cause logistical issues for the military, as the chinook has been dubbed the “battlefield workhorse” since the 1960s.

Fort Rucker, which is primarily a flight training installation, has just over 40 CH-47 Chinooks.
