    Is Oxygen Hose Length an Issue?

    We talked about the May 16 cockpit fire on a United Boeing 757 (New York to Los Angeles) that made an emergency diversion to Dulles. That event involved an airborne cockpit fire so extreme that the pilot reached for the fire extinguishers to put out flames coming from his windshield—but he was brought up short by the length of the oxygen hose. In the smokey situation, it must have been a special concern to have the oxygen mask rip away from the pilot’s face. I can only assume there is other essential gear stored and unreachable due to the length of the hose, because I haven’t seen anyone talk about solving the hose length issue by moving the extinguishers closer.

    In fact, on some Boeing 757 and 767s the length of the hose attached to the pilot’s oxygen mask and smoke goggles is under scrutiny now by the FAA for being too short to reach the fire extinguishers. Apparently Boeing has resisted lengthening the hose because of the danger of the pilot getting tangled in the hose.

    Since the FAA is looking into the issue of the possibility of the hoses being too short, one can not help but wonder if this problem were a factor in the May 22 – Air India Express Flight 812 Boeing 737-800 crash at Mangalore International Airport, or the Jan 25 Ethiopian Airlines Flight 409 Boeing 737-800 that crashed into the Mediterranean Sea shortly after take-off from Beirut. How do we know that too-short hoses did not contribute to those tragic events?

    Conversely, if the 737 hose length is not too short and allows the pilot to reach where it essential for the pilot to reach, and there is no hose problem on the 737, then why has Boeing not corrected this problem on 757s and 767s?

  • Ethiopia Flight 409: Dubious Claims Circulate the Blognet

    There’s a general consensus among the people who deal with terrorists that terrorists like to take credit for disasters, even when they’re not responsible for them. Ownership of violence is part of the whole extremist “psych-you-out “ ideology. To claim responsibility for an act one did not do to is to “claim” one for the malevolent gipper, to make one appear more powerful, especially when actually helpless, and/or to appease whomever one is confessing to with false collateral by churning out false confessions.

    But consider this: if I say I am Santa Claus or the Easter Bunny, it does not mean I am Santa Claus or the Easter Bunny. Legally, it’s going to take more than tall talking and word of mouth to establish that claim in court. It will take heavy duty concrete proof to make that claim stand up in a court of law. The head of the Engineering Department at the BEA (France’s version of the NTSB, the Investigation and Analysis Bureau) Christophe Ménez said in an interview … that evidence shows that last month’s Ethiopian plane crash was not a result of an explosion. “The fuselage and other heavy parts, such as the engine, all sank together, and the plane’s wreckage was in close proximity, which indicates that the airliner did not explode. ”

    The investigation of Ethiopia Airlines Flight 409 so far does not develop a case for terrorism having anything to do with causing the crash. But even if it were true (and we don’t think it is), the primary liability rests with the operator, Ethiopia Airlines. This is not a legal opinion, just my own opinion.

    Now let’s speculate. If it were a terrorist act, it might derail a law suit against component manufacturers in the United States, but an experienced lawyer would tell us that if an act of terror downed the plane, it would not budge legal claims against Ethiopia Airlines. Under the various treaties that govern air travel, the operator has the primary responsibility for that innocent passenger who paid good money to get on that plane.

    The big news services are not the source of this claim; it looks like it is coming from a blog network, so it appears to be a rumor rather than fact, or a rehash or repost of an earlier theory. There is no plausible evidence of sabotage.

    But we are still hoping for more evidence, and for the families, more remains, to be discovered by the Odyssey Explorer in the ongoing marine search for definitive evidence.

    The terrorism theory has already been postulated and discarded once so I don’t give much credence to it. But more than anything, I regret seeing these things crop up to stress the victims families even more. They’ve already been through too much; and the investigation is going to take a long time. They have a long way to go.

  • FAA Standards Tested

    George’s Point of View

    I hope that all of St George’s licensees have been retested.

    Anthony St. George was convicted and sentenced to prison on 15 counts of conspiracy and submitting false statements on Federal AviationAdministration (FAA) certifications. At the time, St. George was a designated mechanical examiner for St. George Aviation whose job was to administer FAA tests air-frame and powerplant tests to mechanics after mechanics took the prescribed class.Not only did St. George provide test answers, he skipped segments of the tests and issued certifications when the office was closed.

  • Expert Opinion: Fatigue and Bad Choices

    For some things, you don’t need experts.

    Anyone who has ever attempted driving cross-country without taking an overnight knows the answer to the question of whether or not fatigue affects your judgment while driving. Of course fatigue has an affect on making serious assessments. It happens while driving on the nation’s highways, so why should it be any different on the nation’s skyways?

    But of course the experts have to chime in. At least this time they agree with the rest of the real world that fatigue is hazardous to judgement. Furthermore, there is airline culpability here, since those low-wage pilots were flying cross-country just to get TO work, there’s no way they could start their shift fresh. Pilot Marvin Renslow had flown from his Florida residence to Newark and either had no hotel room, stayed up, or napped in the Newark crew lounge (which at Colgan Air is a fireable offense.) His abysmal training/test record stands as its own worst advocate. Co-pilot Rebecca Shaw who lived in Seattle had just pulled an all-nightter so she could get a free ride to work–and she was sick.

    The pilot and co-pilot of the Colgan flight were facing multiple issues. The speed of the plane had dropped. Ice had gathered on the wings. The shaker stick had engaged. Neither pilot nor co-pilot appeared to be familiar with how to handle icing; neither were adequately grounded on emergency procedure; neither knew whether this was a wing or tail stall (which affected whether or not the nose should be down); and neither knew what to do with the shaker stick.

    That the pilots were discussing subjects not related to flying is a “red herring.”

    Admittedly, they could have been paying more attention to what was going on, but think of how many of us who have driven long distances use conversation to help us stay alert in similar circumstances. Even if they’d been speaking exclusively of the emergency, doing so would not have been the magic bullet that filled in the gaps left by inadequate training. They still would not have known what to do.

  • Nothing Happened in Nashville…

    Remember the story of the boy who cried wolf? In the days when people’s lives depended on their herds, someone had to be there to watch over them. So our boy had the watch, and got tired, or was mischievous, or maybe he fell asleep, or was just plain old bored. Whatever the reason, he claimed to see a wolf when there wasn’t one. So the whole town went into overdrive emergency mode, and turned out in full force to protect the herd. But of course, there was no wolf. Everyone breathed a sigh of relief, patted the boy on the back sympathetically, and went back to what they were doing. Everything got back to normal. After a time, the boy, for whatever the reason, got bored again, or tired, or mischievous. Maybe he liked all that energy or attention he got the first time he’d cried wolf. Whatever the reason, he did it again. And of course the town rose up into emergency overdrive again, bringing swords and pickaxes and plowshares and whatnot, but of course, there was no wolf. So when the townspeople headed back, they didn’t amend their procedures; they didn’t put up cameras, or send a new watch team in. No pat on the back for the boy this time–they just went back to what they were doing. And of course, the infamous third time he called, the town rose to the occasion, but there was no occasion. They had another chance to amend their procedure, but no, this time they glared at the boy, and went back to what they were doing. This is when they should have put someone else there, because he’d lost all credibility. It was inevitable that now that everyone was desensitized, the wolf was going to show up. And so he did. And of course, the boy cried wolf this time because this time there was a wolf, and of course as the story goes, by now no one believed him when he sounded the alarm, even though this time it was really an emergency.

    So, this is why I have been wrestling with whether or not to write about the Northwestern Nashville event. The one where the plane was stopped over a suspicious looking package that turned out to be christmas ornaments. The one that has figured so highly in the news. It seems to be very important that 75 passengers and five crew members were evacuated, screened and for two hours, dogs and a bomb unit searched the plane and nothing was found. The plane went on its way.

    But here’s the rub.

    This was an emergency procedure. The package could have been dangerous. It could have been a red herring, while something else was on the plane that was more dangerous. The boy did NOT cry wolf. The boy did his job. The herd was safe, and went on its way unharmed.

    This is a non-event. Passengers reboarded after about two hours and the flight continued. A few people had their schedules rattled. Maybe a little more importantly, a few people had their calm rattled, but ultimately nothing was lost but a few hours. This was a good thing for all concerned. Can you say “Your Homeland Security Dollars At Work?”

    It is important for us to remember that the watch worked.

    Perhaps the whole emergency procedure turned out in the long run to be nothing more than a drill. But the value of a drill is that it hones skill. Practice builds expertise.

    I am sure in some countries, anti-American spindoctors are chuckling over keystone-cop-three-stooges retellings of our efforts at national security. I hope there are no such versions in this country. Because the watch worked.

    The package could have meant another disaster. It could have been bad news. It could have meant the end for 80 individuals, and grief and terror for the rest of the country. Instead, it was just another piece of lint that got caught in the filter.

    We should be thrilled at the effectiveness at the filter, not ridiculing the process anywhere (except perhaps on Saturday Night Live or in the desperate humor of late night talk show hosts no one is taking seriously anyway.)

    We should not be distracted by this non-event. We should be glad that our emergency crews are out there, doing their jobs, flexing their muscles, refining their procedures and keeping the watch. In the words of Winston Churchill, It is no use saying,” ‘We are doing our best.’ We have got to succeed in doing what is necessary.”

    We are doing what is necessary.

    The boy has not cried wolf. Neither should the media.

    The Delaminating 787: Causing Problems and Recalls


    The Boeing 787’s composite skin is under the eye now, with the carbon fiber structure deconstructing after improperly joined structural stiffeners fail. Longerons are installed on a wound carbon fibre barrel, frames and longerons are secured to the skin to strengthen the structure, and reinforced by shims. Without shims making a tight fit, damage incurs to the carbon fiber.

    The problem has been located on an All Nippon Airways (56), and two Qatar Airways airframes (57 and 58), all of which originate in Everett Washington.

    More 787s are expected to turn up with the same problem.

    The structural stiffeners are failing in the location of the Alenia Aeronotica-built horizontal stabiliser.

    Boeing confirms that the problem is a “straightforward repair that should cause no short-term safety concern.”

    Inspections are already underway, and strategic plans for repairs are on the drawing board. A 2010 problem involved the teardown and reinstallation of some Alenia Aeronautica-built horizontal stabilisers which had been assembled without adequate shims.

    In George’s Point of View

    updated


    According to a Reuters article, Boeing is saying publicly that this will not affect production.

    It SHOULD affect production.

    Boeing needs to slow down and get it right. Thousands of souls will fly in these “things.” Boeing’s got to have it right. Instead of ramping up, slow down production. What good is an ambitious target rate if the planes come out needing SAFOs (Safety Alerts for Operators)?

    Too fast reminds me of Airbus.
