US Army attack helicopters crashing at historically high rate amid mechanical issues

US Army Apache Helicopters Crash at Historic Rate

Healfromzero.com – US Army attack helicopters crashing at a historically high rate has become a pressing concern after five major Apache mishaps were logged since October, according to a CNN review of publicly released military accident data. A deadly incident earlier this month near Fort Hood, Texas, killed two soldiers, ignited a wildfire, and prompted the Army to temporarily suspend routine Apache training flights. With that crash, fiscal year 2026 is tracking toward the second-worst year for Apache flight accidents since the AH-64E model entered service in 2011.

A Deadly Spike in Flight Accidents

The Army confirmed that the training-flight pause—which exempted units deployed to the Middle East—ended Wednesday. This year’s tally of Class A mishaps (the Army’s designation for any accident that kills or permanently disables a person, destroys an aircraft, or causes at least $2.5 million in damage) already rivals the service’s worst recorded rate from fiscal year 2024, when nine major Apache crashes occurred amid a broader surge across all Army helicopter types. That earlier spike was attributed to reduced pilot experience and heightened training complexity following Russia’s invasion of Ukraine, which drove a renewed emphasis on preparing for large-scale conflict. The drivers behind this year’s uptick remain less clear.

The July edition of the Army’s official flight-safety newsletter reported that just over half of this year’s Apache incidents, including lesser ones, were primarily linked to human error. How many of the most severe crashes stem from equipment malfunction is not yet established, though the newsletter noted that “a catastrophic transmission failure was noted in one Class A mishap.” CNN calculated this year’s major-crash rate at roughly 6.24 per 100,000 flying hours, based on publicly released incident data combined with flight-hour estimates supplied by the Army.

Transmission Failures Under Investigation

Through August 15, the Apache fleet had accumulated approximately 80,171 flight hours—42,971 hours logged through March 31 per an internal safety newsletter, plus an estimated 37,200 additional hours reported by an Army safety spokesperson. For comparison, fiscal year 2024 recorded a rate of 7.02 major crashes per 100,000 hours for the same aircraft.

Two internal safety messages obtained by CNN describe significant problems with the E-model Apache’s transmission, a component whose failure can disable the tail rotor, electrical power, and hydraulics simultaneously. Loss of those systems can throw the helicopter into a sudden spin and compromise flight controls. As of mid-July, the root cause remained “under investigation,” according to a safety message issued at the time.

“We express our deep sadness over the loss of the two Soldiers near Fort Hood,” said Maj. Montrell Russell, an Army spokesperson, in a statement to CNN. He declined to disclose preliminary findings on the transmission investigation or the causes of the Texas crash, citing “special controls and release protections” that bar detailed technical aviation information.

The initial April safety message—first reported by trade publication Defense One—identified 70 potentially faulty transmissions and grounded all affected aircraft pending repair. A follow-up message in mid-July added 10 more suspect units to the no-fly list while reiterating that the root cause was still unresolved. Together, the two directives affected roughly one-tenth of the Army’s attack helicopter fleet. An Army official told CNN in early June that all affected Apaches remained grounded; the service did not respond to follow-up questions about whether any have since returned to flight.

CNN obtained an August 14 internal Army order that formally cited both transmission safety messages in its references for the training-flight pause following the Texas crash. Russell cautioned that “including these messages in safety reviews does not imply causation for any individual mishap,” underscoring that the investigation into US Army attack helicopters crashing at elevated rates is ongoing.

Frequently Asked Questions

How many major Apache crashes have occurred in fiscal year 2026?

Five Class A mishaps involving the Apache have been recorded so far in fiscal year 2026, including the fatal Texas incident that killed two soldiers.

What is causing the elevated crash rate?

The Army has not confirmed a single cause. A July safety newsletter attributed just over half of all Apache incidents (including minor ones) to human error, while at least one Class A mishap involved a catastrophic transmission failure. The root cause of the transmission problems remains under investigation.

How many helicopters were grounded due to the transmission issue?

The combined effect of the April and July safety messages impacted roughly one-tenth of the Army’s Apache fleet. The Army has not disclosed how many, if any, have returned to flight since early June.

When did the training-flight pause end?

The Army announced the pause ended Wednesday following the Texas crash. Units deployed to the Middle East were exempted from the restriction throughout.
