US Army grounds all Chinook helicopters worldwide: Report

The U.S. Army has ordered its entire fleet of CH-47 Chinook helicopters – approximately 400 — grounded this week over engine fires, The Wall Street Journal first reported Tuesday.

Officials told the publication that The U.S. Army Materiel Command grounded the Chinook helicopters after engine fires had occurred “in recent days” but had not caused injury or death. The grounding went into effect on Monday or Tuesday, according to officials.

The suspected cause of the engine fire is a fuel leak attributed to a part found in more than 70 of the helicopters with Honeywell engines, officials told WSJ.

The Chinook – named for the Chinook Native American Tribe – was built by Boeing. It was introduced in 1961 and was prominently used in the Vietnam War. The helicopter also played a major role in Desert Storm.

It is capable of holding up to 26,000 pounds of cargo or 55 personnel, and can travel at speeds of up to 160 knots. It is the only heavy-lift cargo chopper to support combat operations, according to the U.S. Army.

Boeing has been upgrading the Chinook to the Block II upgrade program with “redesigned fuel tanks, a strengthened fuselage, and an improved drivetrain.”

Last month, a Chinook helicopter with two military veteran pilots crashed while battling a wildfire in Idaho. Both pilots were killed on impact. The pilots were employed by ROTAK Helicopter Services in Anchorage and had been contracted to fight the fire.
