Southern California has long been the nation’s runway incursion epicenter. Among the country’s 25 busiest commercial airports, John Wayne Airport in Orange County, Long Beach Airport and LAX ranked one, two and three in runway incursion rates – measured by incidents per 100,000 flights – since 1999. The three airports also topped the list for the total number of incidents, regardless of size. Aviation officials call the geographic clustering a coincidence. “There’s no common theme or thread, nothing unique to Southern California,” said FAA spokesman Donn Walker. Spokeswomen at Long Beach and John Wayne airports said most runway incursions at their facilities involved small, private planes. The problem at LAX has commanded the most attention: It mostly serves commercial aircraft, giving it the greatest potential for a catastrophic accident. LAX has seen between six and 10 incursions annually since 1999, though FAA officials caution those numbers can be misleading. None of LAX’s eight incursions in 2005 posed an imminent collision risk, Walker said. Airports in Chicago, Newark, New York and Kentucky had fewer incursions, he said, but experienced more serious individual events. Not that LAX has been problem-free. In November 1999, the pilot of a departing United Airlines Boeing 757 pulled up early to avoid barreling into an Aeromexico MD80 that had mistakenly taxied into its path. The United plane – which counted among its passengers then-U.S. Sen. Bob Dole and his wife, Elizabeth Dole – skimmed an estimated 200 feet over the smaller jet, according to a LAX report. In an August 2004 incident that chillingly echoed the 1991 crash, the pilot of an arriving Asiana Boeing 747 swooped about 200 feet over a Southwest jetliner that an air traffic controller had positioned on the runway where the jumbo jet had been cleared to land. Authorities blame the airfield’s layout for most of LAX’s runway incursions – including six in just two months last year. LAX has two sets of parallel runways. Planes land on the outer runways and, while taxiing to their gates, cross the inner runways, which are used for takeoffs. While other airports have similar configurations, LAX is the nation’s fourth-busiest airport in terms of flights and has a relatively small, congested airfield. Looking down from the cab of the LAX control tower, the potential for problems is obvious as a succession of arriving jets nose up to a stop line before reaching the inner runway as other planes roar down it. “I always equate it to the same act of faith as pulling up to a traffic signal and you’ve got a green light and you see somebody pulling up in the other direction,” said Mike Foote, the air traffic controllers union representative at LAX. In other words, you assume – and hope – they’ll stop. The FAA attributes most of LAX’s incursions to pilot error, but pilots and air traffic controllers say the causes are more complex. “It’s just like an accident – it’s never one item, it’s a series of things,” said Jon Russell, a United Airlines captain based at LAX. For example, pilots may miss instructions because they’re preoccupied with landing or digesting last-minute runway assignments, he said. Authorities have tried to address LAX’s problem by installing new technology in the control tower, stressing vigilance to airline pilots and placing “hot spot” warning signs on the LAX charts pilots use. Additionally, LAX has spent $8 million on better airfield signs, lighting and markings, said airport spokesman Paul Haney. And, next year, the airport is scheduled to get a new ground radar system that will give air traffic controllers precise information about the locations of planes on the airfield. It all comes against a backdrop of a major airfield rejiggering that should give air traffic controllers greater control over the planes they guide. The project faces environmental lawsuits, but the airport hopes to settle those and begin construction early next year. 160Want local news?Sign up for the Localist and stay informed Something went wrong.

Los Angeles International Airport and two others nearby have the worst runway safety records among the nation’s busiest airports in recent years, a review of federal aviation data shows. Federal officials are most concerned by the situation at bustling LAX, where commercial jets have come perilously close to crashing at least twice since 1999, the first year of data reviewed by The Associated Press. The problem persists because, despite millions spent to reduce violations known as runway incursions, LAX’s airfield has built-in flaws: It’s too tightly packed and arriving aircraft must cross runways used for takeoffs. Nationwide, the number of incursions has dropped about 20 percent from its 2001 peak. Airports in Boston, Philadelphia and Newark had unusually high numbers of incursions in fiscal year 2005; those in Denver, San Francisco and New York’s La Guardia had none, according to federal records.

Now, after years of planning, the airport plans a permanent fix: a $250 million airfield renovation that officials say should eliminate most of the violations. Federal authorities and LAX officials say that, using interim fixes, they have reduced the severity of the incidents, if not the number. “I don’t feel there’s an enormous safety problem there right now (but) the numbers do concern us,” said Dave Kurner, the Federal Aviation Administration’s regional runway safety program manager. Runway incursions occur when a plane or vehicle on the ground gets too close to a plane that is landing or taking off. The worst aviation accident in history occurred on a runway in 1977 when two jumbo jets collided in the Atlantic Ocean’s Canary Islands, killing 582 people. At LAX, 35 people died in 1991 when an air traffic controller cleared a jet to land on the same runway where she had positioned a commuter plane for takeoff. Nationally, incursions spiked at 407 in fiscal 2001, FAA reports show, before dropping to 326 in fiscal 2004 – about the same level as in 1999. Boston’s Logan International bucked the trend in spectacular fashion by recording 15 incursions last year after experiencing just four from 2002 through 2004. The number of incursions that resulted in near crashes also dropped.
