Quoting 96adrian (Thread starter): Does anyone know which aircraft was involved? |
Quoting EBGflyer (Reply 1): It is concerning to hear though that slides did not deploy properly. |
Quoting MerlinIIIB (Reply 6): Slides on both sides did deply. Overwing evacuation with take-off flap only may have contributed to number of casualties. |
Quoting migair54 (Reply 8): In the picture i can see in another web the slides are all deployed. I can´t believe that no slide were deployed, they are arm even before the plane start moving, as soon as the doors are closed. |
Quoting migair54 (Reply 10): I think some people state that the slides didn´t deploy because they didn´t know that a B737 has no slides over the wings exits. Because it´s very clear in the pics that the slides are deployed in all the 4 doors. |
Quoting KaiGywer (Reply 12): Huh? |
Quoting bueb0g (Reply 14): No slides required for the overwing exits due to regulations coming into force after the 737 program was active, and existing aircraft programs being grandfathered. 777236ER is saying Boeing should be installing the sides anyway. |
Quoting SASDC8 (Reply 15): Yes but flaps should be at 40 degrees for overwing evacuation. The CC crew obviously did not do their job properly. |
Quoting aluminumtubing (Reply 16): After, and ONLY after a PROPER investigation, should a determination be made as to how the crew acted. |
Quoting SASDC8 (Reply 17): I totally agree with you, and I now see that my post was a bit more judgemental than it should have been. Sorry. |
Quoting Fabo (Reply 20): It is, btw, possible that the crew DID put the flaps lever in fully extended position, however some airlines mandate no hydraulic pressure during pushback due to nosewheel steering. Some airlines use pressure in single system |
Quoting SASDC8 (Reply 15): es but flaps should be at 40 degrees for overwing evacuation. The CC crew obviously did not do their job properly. |
Quoting 777236ER (Reply 21): Yet another reason not to rely on flaps 40 for a safe evacuation |
Quoting 777236ER (Reply 11): Yet another example that Boeing need to stop delivering aircraft following rules grandfathered in from the 60s. |

Quoting boeingfixer (Reply 23): Both of you may want to refresh yourself with the regulation per FAR 25.810 regrading escape routes before throwing Boeing under the grandfathered bus. The current regulation states that if the escape route is over a flap, the height must be no more than 6 feet off the ground with the flaps in landing or takeoff position, which ever is higher from the ground. I'm not at our hangar and can't measure the flaps at the moment but I would be hard pressed to say it's out of the regulation of 6 feet. |
Quoting 777236ER (Reply 24): It's over 10ft |
Quoting rfields5421 (Reply 25): Where do you see that number? |

Quoting SASDC8 (Reply 15): Norwegian media is now reporting that the flight attendants left the aircraft before evacuation was complete, and that the did not assist passengers in need of assistance. I know that people in emergency situations tend to think the saw things that really did not happen, but It true could Corendon Airlines get in trouble for it? |
Quoting 777236ER (Reply 21): Yet another reason not to rely on flaps 40 for a safe evacuation |
Quoting 777236ER (Reply 19): Never mind that the 737-800 is only about 29 people over 25.807 too, and the front doors are a nightmare when armed (so much so that crew often can't open it...no assist here!!) |
Quoting KC135TopBoom (Reply 29): So when Airbus gets the certification for the A-320NEO models, they should not grandfather the airplane to the 1980s? |
Quoting KC135TopBoom (Reply 29): This perticular airplane was originally delivered in 2009, so it has been inservice for 3 years, at least. |
Quoting KC135TopBoom (Reply 29): Boeing will install slides on any exit where it is not mandatory |
Quoting 777236ER (Reply 11): Yet another example that Boeing need to stop delivering aircraft following rules grandfathered in from the 60s. |
Quoting Fabo (Reply 20): Otherwise 2 fractures of a planes worth of evacuation in a fire event is not that bad I think. |
Quoting 777236ER (Reply 11): Yet another example that Boeing need to stop delivering aircraft following rules grandfathered in from the 60s. |
Quote: (d) Means must be provided to assist evacuees to reach the ground for all Type C exits located over the wing and, if the place on the airplane structure at which the escape route required in paragraph (c) of this section terminates is more than 6 feet from the ground with the airplane on the ground and the landing gear extended, for all other exit types. (1) If the escape route is over the flap, the height of the terminal edge must be measured with the flap in the takeoff or landing position, whichever is higher from the ground. |
Quoting 777236ER (Reply 24): It's over 10ft |
Quoting 777236ER (Reply 26): 25.810 takes no credit for flaps or wings, it's about height to the door. |
Quoting 777236ER (Reply 26): 25.810 takes no credit for flaps or wings, it's about height to the door. It makes it totally clear that a new type certificate with 737 over wing exits would need slides |
Quoting BMI727 (Reply 32): Wrong. The bottom of the overwing exit is ten feet off the ground. The "terminal edge" of the escape route, which in this case would be the flap in takeoff position, is barely over six feet, if at all. |
Quoting BoeingVista (Reply 34): So you slide and drop 6 feet... This seems like a safe escape practice to you? |
Quoting aluminumtubing (Reply 16): Yes, and Maybe, maybe not. YES, the flaps should be fully extended to aid the passengers as part of the emergency evacuation checklist. The cockpit crew MAY or MAY NOT have acted improperly. There could be a reason the flaps were not extended to 40 other than crew error. After, and ONLY after a PROPER investigation, should a determination be made as to how the crew acted. |
Quoting ricknroll (Reply 36): Either way, it's obviously not a workable procedure to expect the crew to set the flaps in an emergency like this. Boeing needs to do the right thing by it's customers and passengers. |
Quoting BMI727 (Reply 37): The certification requirements explicitly do not expect the crew to set the flaps to 40. It's part of the checklist, however certification assumes that it is not possible and the evacuation must be accomplished with the flaps in whatever state they happen to be in. |
Quoting ricknroll (Reply 38): If that height is enough to break bones, it's enough to split open someone's head, when there is no need for it, and newer aircraft are required to be safer. A broken leg by itself can be a very serious injury for an older person. |
Quoting BMI727 (Reply 35): You wouldn't slide and drop, you would walk to the edge and jump down about 6 feet. I won't say it's the safest thing to do, but I think that if you go to any playground you'll find at least a few kids performing similar feats |
Quoting BMI727 (Reply 35): without the added motivation of escaping a flaming aircraft. |

Quoting BoeingVista (Reply 40): Look I'm not saying its a recipe for death but standards of air safety have been improved, there is NO justification for allowing Boeing to build the MAX to 50 year old air safety regulations, well none apart from money. |
Quoting ricknroll (Reply 36): If the fire was in the cockpit, then the crew probably had to flee for their own safety. Either way, it's obviously not a workable procedure to expect the crew to set the flaps in an emergency like this. Boeing needs to do the right thing by it's customers and passengers |
Quoting BMI727 (Reply 35): You wouldn't slide and drop, you would walk to the edge and jump down about 6 feet. I won't say it's the safest thing to do, but I think that if you go to any playground you'll find at least a few kids performing similar feats, without the added motivation of escaping a flaming aircraft. I've not done it in a while, but I've survived it without injury a few dozen times, so I don't think it's a big deal. Besides, I don't think the regulations are arbitrary. |
Quoting Daysleeper (Reply 30): I'm not sure what your point is here, other than evacuating an almost new 737 means 27 passengers will require hospital treatment - Which is insane, so perhaps that is your point? |
Quoting 2175301 (Reply 39): The problem is that elderly or people with certain medical conditions can break the bones by just falling down when standing on the ground. |
Quoting rfields5421 (Reply 46): Evacuating an aircraft in an emergency isn't safe for anyone. But it sure beats staying in a burning plane. |
