Army Spends Billions on Helicopters With Crucial Flaw: They Overheat

SACRAMENTO, Calif. — The Army is spending $2.6 billion on hundreds of European-designed helicopters for homeland security and disaster relief that turn out to have a crucial flaw: They aren't safe to fly on hot days, according to an internal report obtained by The Associated Press.

While the Army scrambles to fix the problem — adding millions to the taxpayer cost — at least one high-ranking lawmaker is calling for the whole deal to be scrapped.

During flight tests in Southern California in mild, 80-degree weather, cockpit temperatures in the UH-72A Lakota soared above 104, the point at which the Army says the communication, navigation and flight control systems can overheat and shut down.

No cockpit equipment failed during the nearly 23 hours of testing, according to the Pentagon report, prepared in July. But the report concluded that the aircraft "is not effective for use in hot environments."

The Army told the AP that to fix the cockpit overheating problem, it will take the highly unusual step of adding air conditioners to many of the 322 helicopters ordered.

The retrofitting will cost at least $10 million and will come out of the Army's budget, according to the Army.

California Rep. Duncan Hunter, the ranking Republican on the House Armed Services Committee, told the AP that the lightweight helicopter will still have too many weaknesses.
