Exceeding Floor Loading Restrictions.
 

I would like people input re damage done, of busting floor loading in aircraft.

Does anyone know of any reports of such incidents?

Eg, like floor loading maybe like 100kg per square foot.

Thanks in advance.

Would need to know what type of a/c you are talking about. 100kg/sq.ft would not be a problem on a 744F.

Exceeding floor limits tends to be not good for the floor beams.

Chances are nothing serious will happen... at first. The aircraft is built to withstand a certain load factor at the maximum floor loading.

Then you have a hard landing or hit severe turbulence, getting close to the limiting load factor... and the floor collapses. Floorboards or seat tracks/seat track support structure fail and you end up with aircraft structure, cargo and underfloor aircraft systems entangled in one another.

The last item would be the main concern. You may find hydraulic lines, environment system ducting, packs, avionics, fuel lines and control cables there, none of which are likely to react well to having floor beams crash down upon them.

In short - don't. :)

The result I've actually seen is cracked floorboards, with no further consequences. Not due to flying with floor load limits outside of tolerances, but due to exceeding them while loading. Expensive.

On a sidenote, try calculating the floor loading under the heels of a pair of high-heeled shoes... ouch! Then try telling a 50 kg woman that you have to place spreaders in the aisle before allowing her to board... double ouch! :D

The twin otter has flor loading on many of the 100-200 (two long rails) of only 100lbs per square foot.

The 300's (three long rails) has 200lbs per square foot.

Not much when taking minning stuff.
