"Overpressure"

[sigmet]

On June 16, captain Valerie Wells, a 30-year-pilot, was scheduled to fly an Airbus A330, which can carry nearly 300 passengers, on a flight from Philadelphia to Rome. But she declined to fly because of failures of both the auxiliary power unit, a backup source of electrical power, and the "hot battery bus," a primary source of electrical power.

After the crew and passengers had returned to the gate Wells, in a particularly unusual event, was escorted out of the airport by security officials. Subsequently, a second crew of three pilots also declined to fly; the aircraft was repaired and underwent a rigorous inspection, and a third crew took off about six to seven hours late.

In seeking to publicize the incident, the U.S. Airline Pilots Association took out a full-page advertisement in Friday's edition of USA Today. The ad proclaimed that US Airways put "revenues first, safety second.

"The intimidation of flight crews is becoming commonplace at US Airways, [which] works to maximize their revenues by pushing their employees to move their airplanes regardless of the potential human cost," said the text. The ad referred readers to a website http://www.USAirlinePilots.org/SafetyFirst.

In a letter to employees on Friday, Robert Isom, chief operating officer, wrote that "USAPA has embarked upon a smear campaign that in reality is all about contract negotiations, not safety.

"I can tell you unequivocally the union's claims are outlandish, false and a disservice to the 32,000 hard-working employees of US Airways," Isom wrote. "Safety has been and always will be the top priority at US Airways, as it is at any airline."
