EV 742-landing In HHN - What Happened?

Thu Apr 12, 2012 5:26 pm

Surely you have also seen the picture of the Evergreen B 747-200 landing in HHN currently shown on the photo search engine page:

I am curious to find out what happened? Is there any pilot out there who can share some more details. I remember WILCO737 recently posting “they rotated her onto the runway” or a similar expression when commenting about a hard landing of another 747 (TUI fly). Is this what happened here as well?

I tried to find out the distance between the aft fuselage and the runway and used the original picture. I hope this acceptable and not breaking any rules (of course, only shown here for dicusssion). If not, please delete. Thanks to Marc Lehman for this amazing photo.

This looks like possibly jammed brakes, and some pretty serious smoke. The dust/smoke comes from directly behind the wheels, and doesn't start further back, as in a tail strike. My observation...

Yes, that can happen. As I explained in the other thread. If you start the flare too late, then you rotate the gear into the runway. Looks like this happened. Or they triet to make a very smooth landing and flared and flared and flared, nose comes up higher and higher and then suddenly the lift is not enough anymore and you 'drop' the last inches onto the runway. That causes a rather hard touchdown and a lot of smoke.

Doubt that. Then it would've made it into avherald or another website as it would cause some tire failures if the brakes are jammed and the anti skid system doesn't work anymore.

Agree, looks like they got too slow, that is a far higher landing attitude than normal.



Lucky they did not hit the tail.
The best contribution to safety is a competent Pilot.

The hard landing may have caused a tyre failure, they are not uncommon, and would account for the additional smoke.
