Panic as jet’s cabin walls crack on flight to Dallas

SAN FRANCISCO — A Dallas-bound American Airlines flight that departed from San Francisco International Airport turned back and made an emergency landing after some of the cabin’s wall panels cracked loose, aviation and airlines officials said.
The captain of the Boeing 757 decided to turn around an hour into the flight to Dallas/Fort Worth International Airport because of a possible blown air duct, American Airlines spokesman Matt Miller said.

Flight 2293 departed from SFO shortly before 1 p.m. Monday and landed without incident about 2:15 p.m. No one on the plane with 184 passengers and six crew members was hurt, he said.

“The captain elected to return to San Francisco and landed the plane safely,” Miller said.

Even though the plane’s problem is related to pressurization, the cabin did not lose pressure and oxygen masks did not deploy, he said.

Flight attendants told passengers the problem was “cosmetic,” a passenger said.

Aviation safety experts agreed with that assessment and said that while it is disconcerting for passengers to see any piece of the plane break, the cabin’s wall panels are not part of the plane’s structure.

“The plastic wall has no meaning to the safety of the plane. They are there so you don’t have to look at the bare walls,” said Robert Ditchey, an aeronautical engineer with four decades of experience.

“On the other hand, it’s not normal for this to happen to a side wall,” added Ditchey, a former U.S. Navy pilot. “Someone is going to have to fix this airplane.”

James Wilson, of Kyle, Texas, said he and his fellow passengers knew there was a problem within minutes after takeoff from San Francisco. Wilson, 32, an amateur race car driver returning from a competition in Northern California, said they felt the fuselage violently shake and heard popping noises coming from outside of the plane as it made its initial ascent.

Then they watched in horror and screamed for the flight attendants to come as interior panels on both sides of the aircraft pulled apart from the walls.

“It was the whole Row 14 on all sides, from the floor to the ceiling,” said Wilson, who was seated in the row right behind and felt a change in cabin pressure. “It sounded like it was popping and banging so loud at first I thought stuff was coming out of the overhead compartments.”

Crew members were “pulling the panels apart and looking for daylight behind there,” he said.

HIGH-ALTITUDE PILOTS SUBJECT TO BRAIN LESIONS


High-Altitude Pilots Subject to Brain Lesions

Decompression sickness, or “the bends,” is typically seen in scuba divers, but high-altitude pilots, who regularly fly at 64,000 feet and higher in planes that maintain a lower cabin pressure than typical commercial flights, are also at risk. Even those that escape decompression sickness are not unaffected by the repeated and prolonged exposure to a low-pressure environment. Researchers have found that high-altitude pilots have a higher incidence of brain lesions calledwhite matter hyperintensities than other military personnel. The pilots show no discernible cognitive impairments, but further study is needed to ascertain whether these lesions are harmful. More… Discuss
