Structural limit of A320 overhead lockers

Is there a published limit for thes lockers and is the latch rated the same?
I don't understand how Easy can have no weight limit.

There is a weight limit placard inside every overhead locker and every stowage on the aircraft. However, I don't see how the overhead locker weight limits can be monitored or enforced.
I have never seen any published data on the latch rating.

I think there have been survivable accidents (not sure which type involved) where the lockers came down on passengers heads.

In Boeing products you will bend the airframe before the lockers comes down.

Thanks to those who replied. I was hoping for a bit more info as flying Easyjet there appears to be no check on the weight going overhead. Only restriction appearing to be what you can lift.

The presumption is that the bins will normally bulk out before the weight limit is reached.

I have a figure of 39kgs per locker in my head. I'd have to check that though. I've not heard of a latch limit. Presumably lateral loads are not considered more critical.

My underline. What is the OVHD single compartment weight limit then?

regards, FD

It's written on the back the lockers of at least one of our fleet - I think it's 39kgs.

That said, I cannot find the limitation in any documentation, from AFM, AMM, CCOM, IPC, etc.

My guess would be a structural weight limit above 39kgs given crew often enjoy posing in the hatbins

The latches also fuse out the load by popping open while the bin stays attached. I've seen bins dislodged completely even on "repairable" aircraft but that also included a pretty big twist in the fuselage during an event.

I'm always amazed by the amount of side walls and ceilings that dislodge in the aft toilets when things get really bumpy

So when they "fuse out" they dump the contents on the heads of the pax below.

Safety really is a negotiable item these days isn't it.

Maybe the AMM or IPC for the decal itself? If it is not included in the AFM or noted in CCOM, then it is kind of pointless.

How many seats per bin there, for 180Y? I reckon 7,5 >> 11 pounds each.

I can't think of any narrow-body that has enough bin space for a carry-on per seat.

A standard ICAO bag (when there was such a thing) is 45cm wide, so the passengers in a triple would need around 55 inches of bin, i.e. considerably more than the seat pitch. Or, put the other way round, on a full flight fewer than 60% of passengers will have space overhead for a carry-on.

Some success!

I looked for the decal in the IPC but no luck.

I have found a reference in the WBM for an A319 that the maximum load for the length (front to back) of the overhead lockers is 660kg on the LHS and 616kg on the RHS.

It also states that the placarded weights must be observed for each locker.

It will be in IPC Ch 11 for sure. Sorry, don't have IPC on hand, so can't check sub para.
