The US Army’s Apache helicopters are crashing at a historically high rate amid a widespread problem with the model’s transmission, according to a CNN analysis of military accident data.

The helicopter type has experienced five major crashes since October, and a deadly mishap earlier this month in Texas killed two soldiers, sparked a wildfire and led the Army to temporarily bar Apache pilots from conducting routine training flights. With that crash, fiscal year 2026 is on pace to be the second worst for Apache flight accidents since a new model of the AH-64 was rolled out in 2011.

The Army announced that the pause in training flights, which exempted units deployed to the Middle East, ended Wednesday.

This year’s rate of major Apache crashes — known as Class A mishaps in Army parlance, meant to represent any accident that kills or permanently disables a person or results in the loss of an aircraft or $2.5 million in damage — surpasses typical years and rivals that of the service’s most severe rate in the 2024 fiscal year, according to CNN’s review of data. The accident rate is based on the number of incidents compared to the total hours the aircraft spent flying, calculated using data that has been publicly released and flight hour estimates for the current year provided to CNN by the Army.
