Excerpt: Yet the conditions for many controllers are far from ideal. A nationwide staffing shortage — caused by years of employee turnover and tight budgets, among other factors — has forced many controllers to work six-day weeks and 10-hour days.
The result is a fatigued, distracted and demoralized work force that is increasingly prone to making mistakes, according to a Times investigation. The findings are based on interviews with more than 70 current and former air traffic controllers, pilots and federal officials, as well as thousands of pages of federal safety reports and internal F.A.A. records that The Times obtained.
While the U.S. airspace is remarkably safe, potentially dangerous close calls have been happening, on average, multiple times a week this year,
The Times reported in August. Some controllers say they fear that a deadly crash is inevitable.
In the fiscal year that ended Sept. 30, there were 503 air traffic control lapses that the F.A.A. preliminarily categorized as “significant,” 65 percent more than in the prior year, according to internal agency reports reviewed by The Times. During that period, air traffic increased about 4 percent.
A
database of aviation safety issues is peppered with recent mistakes by exhausted controllers. A controller at the air traffic control center in the Jacksonville, Fla., area instructed one airliner to turn into the path of another, later blaming being overworked and fatigued. A controller at a facility that monitors the skies above Southern California told a plane to fly too low, attributing the lapse to being “extremely tired” after working “continuous” overtime.
“If I can make a small mistake like that, I can make a bigger one,” the controller wrote in a submission included in the database, which is maintained by NASA.
