Unfortunately, This appears to be the start of Fire Blight, or any of the related blights. Likely, the soil remains too wet for too long without adequate chance to dry out, thoroughly, down to about 5 to 8 cm between waterings.

I would treat with a fungicide, but this is going to take some serious management to correct from here.

Here are some articles that will help:
