Obama's plane aborts landing

Washington - Air traffic controllers directed an aircraft carrying first lady Michelle Obama to abort a landing at Andrews Air Force Base because it was too close to a military cargo jet, officials said on Tuesday, in yet another embarrassment for the Federal Aviation Administration (FAA).

While there apparently was little risk to Mrs Obama, the episode puts the FAA back into the spotlight as officials struggle to calm public jitters about flying that have been raised by nine suspensions of air traffic controllers and supervisors around the country in recent weeks, including five for sleeping on the job.

The first disclosed case of a controller falling asleep on duty occurred March 23 at Washington's Reagan National airport, not far from Andrews.

The most recent was this week when a controller at a regional radar facility near Cleveland was suspended for watching a movie on a DVD player when he was supposed to be monitoring air traffic. The head of the US air traffic system resigned last week.

This latest incident occurred on Monday afternoon when a Boeing 737 belonging to the Air National Guard, one of several guard aircraft used by the White House, came within about 5km of a massive C-17 as the aircraft were approaching Andrews to land, according to the FAA and Major Michelle Lai, a spokesperson for Andrews.

The FAA requires a minimum separation of 8km between two aircraft when the aircraft in the lead is as large as the 200-ton cargo jet, in order to avoid dangerous wake turbulence that can severely affect the trailing aircraft.

No proper separation

The FAA is investigating the incident as a possible error by controllers at a regional radar facility in Warrenton, Virginia, that handles approaches and departures for several airports, including Andrews, where the president's aircraft, Air Force One, is maintained.

The C-17 and Mrs Obama's aircraft didn't have the proper separation when controllers in Warrenton handed them off to the Andrews controllers, a source familiar with the incident said.

Andrews air traffic controllers initially ordered Mrs Obama's aircraft to conduct a series of turns to bring it farther from the military jet. When that didn't provide enough distance, controllers realised that there might not be enough time for the cargo aircraft to clear the Andrews runway before Mrs Obama's aircraft landed.

Controllers then directed the pilot of Mrs Obama's aircraft execute a "go-around" - to stop descending and start climbing - and circle the airport, located in a Maryland suburb of Washington. A go-around is considered a type of aborted landing.

"The aircraft were never in any danger," the FAA said in a statement.

Situation not uncommon

Aviation safety expert John Cox agreed that an accident was unlikely.

"Every professional pilot I have ever known has been in a situation where they were overtaking the plane in front of them and asked to do an S-turn," said Cox, a former airline pilot. "The only issue that could have come up was if they'd encountered the wake of the C-17."

Even then, Cox said, the 737 is a "very controllable" aircraft. "I don't think Mrs Obama's plane would have been in any jeopardy."

Jill Biden, wife of Vice-President Joe Biden, also was on the aircraft with Mrs Obama. The first lady and Mrs Biden had been in New York earlier in the day for a joint TV interview.

The first lady's office declined to comment and referred all questions to officials at the FAA and Andrews. The president's West Wing press office did likewise.

The National Transportation Safety Board is gathering information about the incident but hasn't yet decided whether it will open a formal investigation, board spokesperson Kelly Nantel said.

Increase in errors

The controllers in Warrenton and at Andrews work for the FAA, and it is their job to keep aircraft separated. When aircraft get too close, the FAA counts that as an operation error. Over the past several years, errors by controllers have increased substantially.

In the 12 months ending on September 30 2010, there were 1 889 errors, according to the FAA. That was up from 947 such errors the year before and 1 008 the year before that. Before 2008 the FAA used a different counting method.

Very few of the errors fall into the most serious category, which could result in pilots taking evasive action to prevent an accident. But those instances have also increased. In the year ending September 30, there were 44 such events, 37 in the prior year and 28 in the year before that.

FAA Administrator Randy Babbitt has said the higher number of known errors is due to better reporting and technology that can determine more precisely how close aircraft are in the air.

Bill Voss, president of the Flight Safety Foundation of Alexandria, Virginia, said the kind of spacing error that occurred in the handling of Mrs Obama's aircraft happens every day.

"It was more an embarrassment than a danger," said Voss, a former controller.

The incident was first reported on Tuesday by The Washington Post on its website.
