Are you a building owner, maintenance man or a lawyer?
You question is vague...
Here is my friendly advice!
If you are the owner, don't set yourself up for the liability.
If you are the maintenance man, be careful what you wish for!
If you are a elevator man, go show your supervisor your post...
And if you are a lawyer, tell me the area you are from and I'll recommend a consultant.
More exactly: by inaccurate level stopping I mean the cabin quite often is failing to stop on the exact level of the floor, missing it by a few inches, up to even a feet sometimes. The elevator is still in use, but causing miscomfort for the tenants.
When we called the maintenance company, we failed to demonstrate the defect, as the occurrence rate is only around 10%; you know, when you go to the dentist it stops hurting...
I am electrician, I do not intend to fix it myself, I am just doing a humble research on the defect, if it is usual defect, what is the probable cause, like worn slipping break, or faulty sensor, you must know better.
Thank you for sharing your experience on the issue.

Dome,
The simple answer to your question is breakdowns that result in running on arrival calls, particularly in the lift industry, is common. Sometimes you can try to see what might have caused a fault, anticipate a possible cause and inspect anything for a defect. Most of the time you don't find anything because you need to see the fault happen. But the client can help the mechanic in many ways. Instead of just flighty information on whats happening, they can compile accurate information to assist us. That can be time of day, direction, floor at which it happened, number of passengers etc. That can be very helpful ie it might be the first runs of the day(a warming up issue for a particular type of lift), if only in the down direction( so you don't need to look at the up direction circuits), at what floor level it occurred( it may only be a particular floor), number of passengers( could be a load issue) etc you get the picture even if the fault has cleared. Remember most lift's are designed to reset in some instances. Finally remember that absolute perfect levelling in most instances don't happen and have a tolerance within the design parameters of the lift.
