General question about Boeing's 737's

[Dai.]

Hello!

I watched a documentary the other day about Helios Flight 522?, I can't remember the exact number, but in short it was the one that crashed in Greece


But on the documentary they said that the main fault they could find was a wire in the Boeing 737 that burnt out and it happens in all the other 737's in commercial use today!

The wire that burnt out controls the cabin and plane pressure and with this wire gone the plane de-pressurises and causes the associated after effects but the cabin controls still look fine..


Or at least that was what I understood from it,

Now I don't want to scare anyone, but does this fault still exist or has it be fixed?


Thanks in advance

The Board reported no evidence of wiring failure in Flight 522, and did not mention the G-DOCE incident. Because all available flight data showed the pressurization control in manual mode and the outflow valve open at a constant angle, and because there was no evidence the flight crew ever changed the pressurization mode, the Board concluded that the pressurization system had been set to manual for the entire flight, which caused the pressurization failure.

So, there you are!

If there HAD been a systematic fault with all 737s, then Boeing would have mandated a fix- if it was criticl, it would have led to planes being grounded until the fault was fixed; if not, it would have been fixed at the first possible oppertunity, with a deadline for doing so. Failure to fix would result in the aircraft being banned from (at the very least) European and North American skies.

But in this case, seem the documentary is ill informed.

A plane like the 737 will never be grounded, as was done to the Concorde, as it would cripple the air industry.
All that would happen would be a letter sent out telling all the operators to check/fix the problem as quickly as possible, if one or 2 go down while this is being done, unlucky, its the cost of doing business!
