Boeing 767 Overweight Landing Questions

Wed Jul 15, 2009 12:59 am


Just curious what all is involved after a aircraft, in this case a B767-300, makes a overweight landing. For example, making a air return shortly after takeoff with a medical emergency.

I know that a overweight landing inspection is required, but what all is inspected. Also can these checks be performed while loaded with cargo and pax? Given that in this case there was not a mechanical issue causing the turnback, is it required to download the aircraft first?

Additionally, how do landing speeds vary for the full load. Any examples of a 767-300 at typical landing speeds versus say full cargo/pax + 8 hours fuel?

Thanks for the information,

Some discussion here


It would seem that the severity of the landing would determine whether the inspection is visual (soft landing) or rather more involved (landing above a certain g loading).

Otherwise the circumstances would dictate any procedures followed after landing.

As for speeds, the fuel is around 30-40% of the take-off weight. The pilots here will say whether the landing is faster and/or the flare is to a higher pitch angle.

As stated above, it works in stages.

The AME's check out the FMS to see the vertical speed/Gforce on landing, if it is below a certain point, the check ends.

If not, they go further, opening some panels in succession. Again, if no evidence of damage is found, it ends.

If evidence of some stress is found, then usually the passengers and cargo/baggage are deplaned and the aircraft is grounded pending further inspection.

Every overweight landing I have performed has ended after stage one of the maintenance inspection. The landing was smooth, they are happy, we continue.

As Vspeeds are predicated on aircraft weight, usually the speeds are higher than one would normally see in normal operation. Technique would dictate that the nose attitude is a little lower, as with the higher speeds, combined with the fine Boeing wing of the B767-300 the aircraft has a tendency to "balloon" and normally runway length is a consideration with the heavier weights.

Just as an aside, most of our B767-300s are equipped with fuel dump capability, and when time is not limiting, we will dump fuel for lower speed and shorter runway requirements. So far, I have only performed this task in the simulator!  Smile

Keep in mind that most aircraft have a stipulation that if the vertical speed is less than 360 fpm at touchdown, no overweight inspection is required.

Still write the overweight landing up, but in the write up include the actual landing weight and vert speed at touchdown.
