At fl300 the cabin was about 8.3 /\p. 8.3 lbs per sq inch. I do not know the exact size of the window, I bet one of our A&P guys familiar with the 73 can give those dimension and do the math of the pressure on that window.Originally posted by beefed88 View PostThat is a lot of cabin pressure leaving through a small hole.
I do know this........ Eight psi is about half an atmosphere. This means that while an airliner is flying, there are about ten tons of air pressure pushing outward on each of the doors. Think about that next time you pass the door
on the way to the John.

767 outer window is about 13"X 10". I believe the 737 is a bit shorter and wider.. Looks like the blade failed at the annular filler. Last guy to do a fan blade lube is probably sweating a bit.Originally posted by likeitfast55 View PostAt fl300 the cabin was about 8.3 /\p. 8.3 lbs per sq inch.

Have you heard of "blade stacking" during the cool off of engine shutdown?Originally posted by 68RR View Post767 outer window is about 13"X 10". I believe the 737 is a bit shorter and wider..

Mostly N1 blades. Causes massive vibs on the N1 and N2.
The CRJ-700 G.E. CF34-8C5 did it bad.

Are you referring to blade shingling? Pratt JT9 would do that on occasion.Originally posted by likeitfast55 View PostHave you heard of "blade stacking" during the cool off of engine shutdown?

The Southwest fan blade failure would most likely only be caught by a NDT non destructive testing method. Some engines have time limits on the fan blades like 777 and 757 RR. But not sure about CFM56.2006 Civic SI

Randy, not familiar with that family of engines. Mostly dealt with GE CF6-50's, 80A's and C2's. Did a ton of blade lubes. Usually the moly coating would start flaking off and you would get a N1 vibe. Usually at .9- 1.2 (coming into Tulsa for a MBV) they would schedule a lube. Pull the blades, clean both the blades and hub, recoat and reinstall. The A sump seal would sometimes fail, allowing oil to get into the spinner, which would also show up as a vibe..Originally posted by likeitfast55 View PostHave you heard of "blade stacking" during the cool off of engine shutdown?

The typical cabin window has 600 to 900 pounds of force on it at altitude. Of course it varies, but that is typical. When they do pop, they do so pretty spectacularly.Originally posted by likeitfast55 View PostAt fl300 the cabin was about 8.3 /\p. 8.3 lbs per sq inch.

The GE rep told me that "stacking" is an uneven cooling of the blades causing random gaps between the base of the blades. Once centrifugal force of the rotation of said blades is achieved, on the subsequent engine run-up, the out of balance section causes massive "vibs" in the core and N1.Originally posted by beefed88 View PostAre you referring to blade shingling?

GE solved the problem in two ways, first by increasing the red-line of max vibs. Second, changing out all of our N1 blades after 500hrs run time.Last edited by likeitfast55; 04-22-2018, 03:59 PM.

I never thought about this issue had a small kid been in that seat nor the amount of cabin pressure.
I'm pretty sure I'll try my hardest to not get a window seat and for damn sure keep our seatbelts on for the entire flight.

Better not get behind the wheel anytime soon then either. Fatal traffic accidents happen every day, so that must mean you're next there too.Originally posted by GeorgeG.
