Narrative:

Citation was cleared by norcal for approach to mce; and went to mer instead. He probably was using commercial approach plates where the mer and mce are lumped together. In the government approach plates; the airports are separated as different cities -- atwater and merced. Commercial chart listing mer under merced is probably a very big mistake; and certainly contributed to a very dangerous situation. The government approach plates handles this much better!
