Due to a hole that came into being on an American B757 on October 26th and a crack in a United-Continental B757 on Sept. 11th an inspection of all 757s is coming. This will include all passenger and cargo operators in the United States. I hope there isn't a serious issue here as the 757 is one of my favorite aircraft to travel on as it is with many of you.

I know that old UA has been at this already for months and should be more than half done....they were not waiting. Not a clue on other carriers.

This is something that happens occasionally; it is highly unlikely that it is anything with serious long-term implications. There is apparently a weakness in the design; but by having regular inspections they should be able to catch any others before they progress to the point of decompression as happened on the AA flight.

I'm glad they're moving forward with a SB/SL/AD, but I'm really not that worried: 1050 in service, some of them for going on 30 years, and just a couple of incidents. So yeah, check 'em out, but there's no reason to take the 757 off of your 'favorite flyer' list.

We finished the first round of inspections on AAL of our airplanes, This inspection is due every 300 cycles so we will be at it again in about 6 months, for the next round.

What's the 757-200CB mentioned in the article?

Can anyone comment on the crazy flexing the fuselage does during when hitting turbulence? You don't know how many times I've seen my seat go down while the seat up front goes up like were on a wave. I'm sure its the same effect on other planes as well, but never seen it more pronounced except on the 757. Especially the 757-3. I mean such constant flex would cause fatigue, would it not?

The A346 also has significant flex.

These Alerts come out all the time and more then 95% of the time the general public never hears about it.

I wonder if they are looking for fatigue in places where the fuselage skin has been chemically "milled", just like the 737 classics I would also be curious to know if the Unitanental bird had the problem in the same area of the fuselage as the AA bird that had a rapid depressurizaiton.

This remembers me a littlebit about the middle of the eighties, when there were a series of similiar cases on 727s and 737s, the most well-known case being of course the Hawaiian B 737-cabrio.

It happens on any long-thin fuselage...CRJ1000, 757-300, A340-600 are all more prone to this than most.
Quoting BA (Reply 6): I mean such constant flex would cause fatigue, would it not?
Absolutely. *Any* tension load causes fatigue. Unless the structural engineers screw up, it's all modeled into the load profiles and tested on the fatigue test frames.

That particular situation is worlds away from the 757 incidents which have occurred.
The Aloha 737 was being inspected in an unlit hangar (good grief). Further, several passengers saw the crack when boarding the aircraft.
All things get old; proper maintenance ensures that they can age safely.
The 757 incidents weren't like that at all--these fuselages did something UNexpected.

Yes. If it didn't do that, it would break. Just like the wings. Flexing is how energy is absorbed.

You are right about the Aloha 737. All I wanted to say is that in the eighties there were two incidents in the United States shortly one after the other (not including the Aloha 737) were holes opened during flight.
I think one was a B 727, I remember a picture (it was even shown in the German National TV at that time) of a 727 with a silver fuselage, so eventually it was Eastern.
Haa, I just made a small google research and immediately found something - it was in 1989.
Quote: Eastern Airlines today said an inspection of 46 older Boeing 727s found one with a three-inch fuselage crack in roughly the same spot as a tear that forced a jet to make an emergency landing Monday in Charleston, W.Va.
The plane was grounded at Boston's Logan International Airport, and late today Eastern maintenance workers here found apparent corrosion near rivets on another 727, company spokeswoman Karen Ceremsak said. She said paint was being removed from the area and no other details were available.
