REFLECTOR: belts

[Alex Balic]

I would think that it is much more likely that the fittings were not closed
properly- but the passengers swore that they were-  I can't tell you how
many times I have flown commercial and sat next to someone who did not
connect their belt and test it- and I have had a couple come undone after I
thought they were pushed in all of the way- when I tested them-   as a
guess, I would think that the belt itself would be good for at least a 2000
pound load, and the buckle would be more than that by design. -.8 g would
not put hardly any load at all on the belt even if a "weight challenged"
double belted passenger was wearing it.

The stitching I am referring to is always cross stitched as per FAA
requirement.  Other belts and harness will not have this stitching.  If you
go to a certified aircraft upholstery shop, this is what you will get when a
custom harness or belt is made.


If you dont think this is important read the following.........

The U.S. National Transportation Safety Board (NTSB) recently issued a
preliminary report about an instance of severe
<http://www.ntsb.gov/ntsb/brief.asp?ev_id=20080305X00267&key=1>  turbulence
during which one flight attendant and five passengers on a Southwest
Airlines flight were injured. The report states that "two of the five
injured passengers were occupying seats where the seatbelt fittings failed
and separated."
The incident happened on the afternoon of February 24, 2008, when the Boeing
737-300 aircraft, operating as Southwest Airlines Flight SWA 2809,
encountered severe turbulence during descent for landing at McCarran
International Airport, Las Vegas, NV. The scheduled flight, which had five
crew members and 137 passengers on board, had originated at Ontario, CA.

More details, quoted from the NTSB report: 

According to information provided by Southwest Airlines, the flight was
descending into Las Vegas at an altitude of 11,400 feet above mean sea level
(msl) when it encountered severe turbulence. The captain communicated with
Southwest Operations to arrange for paramedics to meet the airplane at the
gate in Las Vegas. The flight continued and landed without further incident.
Medical personnel met the airplane as requested, and the treated the injured
passengers and flight attendant, classifying their injuries as minor.

A preliminary review of the flight recorder data provided by Southwest
Airlines disclosed that the airplane experienced a vertical acceleration
minimum of approximately -0.761 G, followed 2 seconds later by a positive
peak of approximately +1.762 G. [NTSB ID: LAX08IA065]

Yes.  Its the fittings that failed not the belt, but those were aircraft
belts, who knows what automotive belts would of done.....  Ya wanna take a
chance? :-P
