Yellow Bracket On Top Of SWA 737-700 Wing

Mon Jul 02, 2007 12:26 pm

Spent an hour and a half trying to figure out what this small bracket with a hole in the middle (painted yellow) is for?

A tie-down of some type?

In the event of a water evac, there's a line associated with each overwing exit that is extended, and clips to that yellow bracket, as a guide to get everyone out on the wing.

It took me a minute to figure out what you were talking about, but now I realize. It's also proiment on the A320.
If I remember correctly, it's a tie down for the overwing escape slides on slide-equipped aircraft.

I have a feeling, though, that someone is about to tell me I'm wrong... just a heads-up.

Single loop close in, and a double loop a little further out.

Wouldn't it be just a bracket for tethering the overwing exit chute in ground evacuations? I highly doubt that water evacs are it's primary use... not only because I don't believe that a water landing by a commerical airliner is structurally survivable, but also because in the very unlikely event that a plane comes to rest in water in tact, tying a life raft down to tiny brackets on the wing would be least of everyones worries.

From Wikipedia's entry on "overwing exits"

Use in a ditching
The use of overwing exits in a ditching varies from airline to airline. On aircraft fitted with overwing exits, there is typically a raised "D ring" about a third of the way from the door, on the wings upper surface and is typically painted yellow. This is accompanied by an escape rope found in the frame of the exit after opening and once this rope is attached to the D-ring it will aid passenger evacuation onto the wing to await rescue or to enter the water (depending on the airlines procedures), and on aircraft with life rafts to be launched via the overwing exit, the wing will be used to provide a boarding platform onto the life raft.

On a 737-700 (SWA's at least) there's no chute or slide associated with the overwing exit--it's just an exit.

I think you can safely assume that the intended use here is to have a raft attached to the line only as long as it takes to fill one up with passengers, and then detach it and float off. If the aircraft has already started to sink, common sense should dictate what not to do. Likewise if there's enough buoyancy in those early minutes where the rope can be used. The ALM DC-9 that ditched near SXM back in 1970 stayed afloat for about 10 minutes before sinking.

Difference between a 737/A320 and a DC-9 is where the engines are. I doubt very seriously that a 737 or A320 (or any aircraft with wing-mounted engines) would make a water landing intact without the engines being torn off the wings (and thus, likely the wings themselves being torn off).

Exactly as designed then! The engine mountings are designed to break away long before reaching loading high enough to rip off the wing. If the water is reasonably calm and it's daylight, a successful "landing on water" is conceivable.

Standard procedure is to attach the raft's static line to a structural point inside the cabin (usually the metal frame of pax seats, the bottom of which should be attached to the floor in most circumstances).

The D-Ring on the wing is to attach the guide-rope to. You'd send your first able-bodied evacuee out onto the wing with the rope, with instructions to attach it to aid the following evacuees to disembark. There is no suggestion that you'd attach the raft to it, although you COULD in the most desperate of circumstances, because the static line will automatically break with about 700lb of force exerted on it - so as the aircraft starts to sink, the force will cause the line to snap, as designed.

On the A320, A319 the "double loop" is for "Lifelines", as described by others for guiding pax onto wing. The single ring is for use when the offwing slide deflates. There is a pouch with a hook at the top of the slide whach can be attached to thet ring and holds the top of the slide taught, it can then be held at the bottom by people and used as a hand-held slide.

This is a non-issue because the raft mooring line, which secures the raft to the attachment point, for the life-raft is designed to break away if under sufficient force, i.e. the plane sinks.

Quoting Flybyguy (Reply 7):

On the A320, the overwing evacuation slides cannot be used for a ditching. Water would enter the aspirators because of its position on the wing, preventing inflation. Further, the slide cannot be detached at the overwing. (The main cabin doors can.) Neverthless, for many A320 operators, the primary exit in a ditching is still the overwing exits as they feel it will be above the waterline unlike the floor level exits.

The first reply was correct, then we get lots of theories!
The B737 has no slides or rafts associated with the overwing exits. You are meant to climb onto the wing and slide down the flaps. In theory the first pax out should take the rope and attach it to the yellow ring to stop people falling off the front of the wing. I wonder if it has ever happened, except in a demonstration?

Actually, some carriers suggest sliding off the LEADING edge of the wing on the B-737 as they believe a ditching would severely damage the flaps and trailing edge, which would present a puncture hazard for any portable life-rafts deployed. However, many like WN do suggest sliding to the back as you noted.

This is really NOT an ideal solution, but air carriers suggests on aircraft without slide/rafts (i.e. B737, MD-80, some A320 aircraft) that "frail or injured" passengers be placed in the slide that has been detached and inverted upside down. There is space (several large "pockets") there for a few pax who really cannot hold on.

Otherwise air carriers teach F/As to form a "survival ring" (i.e. everyone link arms and form a circle) and place all frail/injured/children pax in the center to assist them. Again, better to be out of the water than in.

This is the attach point for the life line which is a requirement of 14 CFR Part 25.1411 for ALL aircraft certified for ditching with an overwing exit.

(g) Life line stowage provisions. If cer-
tification for ditching under §25.801 is
requested, there must be provisions to
store life lines. These provisions
must—
(1) Allow one life line to be attached
to each side of the fuselage; and
(2) Be arranged to allow the life lines
to be used to enable the occupants to
stay on the wing after ditching.

A Garuda 737 did ditch into a lake and remained structurally intact...resulted in only 1 fatality

It was actually a river.

In 1968, a JL DC-8-62 landed in San Francisco Bay a couple of miles short of the SFO runway in foggy conditions. Fortunately the water was only about 10 feet deep so the aircraft came to rest sitting on its landing gear on the bottom, with the water about level with the bottom of the passenger doors. The DC-8 suffered very little major structural damage, and was repaired by UA and returned to service about 4 months later. Amazingly, there weren't even any injuries to anyone on board during the unexpected water landing and evacuation into rafts.

The 747-400 does have life lines stored in the ceiling of the L3 and R3 doors. They were not used in this situation. Earlier variants kept the life line in the Flight Attendant doghouse.

It wasn't really a controlled ditching considering that the hijackers tried to take control of the powerless aircraft in the last few moments before water contact.

This attempt doesn't really "count".

As MarkHKG mentions, it was not very controlled. As the plane was about to ditch, the hijackers tried to take control of the aircraft. The resulting crash was largely the result of the struggle. If the pilots had retained control, the aircraft would at least have hit the water wings level.

Quoting Flybyguy (Reply 36):
I know GA planes have ditched intact, but not modern commercial airliners ... perhaps the only airliners that remained intact (or near so) were victims of runway overruns into shallow water.

Flybyguy, I repeat that there have been several successful ditchings, and not all from overruns. Here is some of ye olde Wikipedia listing. Note how many ditchings were successful:
* In 2002, Garuda Indonesia 425 (a Boeing 737) successfully ditched into the Bengawan Solo River near Yogyakarta, Java Island after experiencing a twin engine flameout during heavy precipitation and hail. The pilots tried to restart the engines several times before taking the decision to ditch the aircraft. Of the 60 occupants, one, a flight attendant, was killed.[6]
* In 1970, Antillean 980 (a DC-9-33CF) ditched in mile-deep water after running out of fuel during multiple attempts to land at Princess Juliana International Airport in the island of Saint Maarten in the Netherlands Antilles under low-visibility weather. Of 63 occupants, 40 survivors were recovered by U.S. military helicopters.[7]
* In 1963, an Aeroflot Tupolev 124 ditched into the River Neva after running out of fuel. The aircraft floated and was towed to shore; all 52 on board escaped without injuries.[8]
* In 1956, Pan Am 943 (a Boeing 377) ditched into the Pacific after losing two of its four engines. The aircraft was able to circle around USCGC Pontchartrain until daybreak, when it ditched; all 31 on board survived.[9][10]
* Also in 1956, Northwest Orient Airlines Flight 2 ditched into Puget Sound after the flight engineer forgot to close the cowl gills on the Boeing Stratocruiser's engines. All aboard escaped the aircraft after a textbook landing, but four passengers and one flight attendant succumbed either to drowning or to hypothermia before being rescued.

Quoting MarkHKG (Reply 25):
Actually, some carriers suggest sliding off the LEADING edge of the wing on the B-737 as they believe a ditching would severely damage the flaps and trailing edge, which would present a puncture hazard for any portable life-rafts deployed. However, many like WN do suggest sliding to the back as you noted.

Which Carriers are you reffering to.

Republic Airlines is one. Many corporate jets also recommend the leading edge (Gulfstream, Falcon, Global Express, etc.) .

They use to operate MD-80s.
Similarly, Canadian Airlines recommended on their 737s to jump from the leading edge in a ditching, but they don't exist anymore. (Now Air Canada)

You know, it amazes me how many pilots aren't even aware of the crash history of aircraft. I've had MANY tell me there was never a successful ditching of an airliner. Just last month I had an First Officer telling me that the A320 did not come out until 1995 and that it was NEVER in service with Braniff II. It's a bit frustrating knowing there are THAT many ignorant aviation professionals out and about not really knowing some important history of their field.

In a way, sure. I will agree that it shows a certain education to know some history of what you work with. But then again is knowing the history really necessary? My wife is a wiz at Excel but she can't tell me it was derived from VisiCalc, the first PC "killer app". Does she need to know this? As a computer dude I find that piece of trivia rather fundamental, but she doesn't care. And she can still kick my ass when making a complex spreadsheet.

Having said that, it bugs me when people insist on being wrong. It's ok that they don't know their history, but they should at least then not try to create their own faulty version.

Honestly,

When YOUR job is the safety of passengers and being familiar with MANY possible situations I say yes, it is important that you know the history. Knowing the history or a computer program doesn't affect how you use that program, BUT knowing the crash history of airliners COULD affect how you decide to land/crash the plane.
It's like when flight attendants can't answer simple aviation physiology/environmental questions. I think for people who work in a VERY unique environment daily they should be better educated by their airlines, and thus be able to more effectively and accurately answer passenger inquiries. Just because flying is common doesn't mean people aren't still in awe by the whole process. Just today I had a passenger ask me how fast we were going. I called the CA and asked him...his response, "Are you serious? Oh my GAH!....uh, looks like, uh....450 knots over the ground. Next time just make something up."

So yes, those of us in aviation, in direct responsibility for our own safety AND the safety of passengers should VERY much be as educated as possible about the safety history of the industry...but, we are not.

True.I've spoken to many Flight crew,who though very good in their job are not very well versed about the Aviation world.Guess its an Individuals interest.

Thank God for those life raft tiedowns on WN B737s!!!

For many years, I have been worried about a water landing in Bachman Lake off the arrival end of 13R. We might have to spend weeks in those rafts until the Coast Guard found us or, shudder, wade through knee-deep and perch-infested water to the shore.

Sure, but you didn't say crash history. You were mentioning examples like the entry into service date of the 320. Is the latter really important to operate the 320 safely? The information is trivia at best for a pilot.

I will agree that knowing something about past crashes is important. He or she needs to know the aircraft and have an understanding of risks and problem resolution. But entry into service dates? I think it's too much to ask for everyone working in aviation to be as obsessed with the industry as we are.
