Narrative:

Small aircraft X, row-cos-ioc-fnl, route of flight. I took an automated handoff from cos approach. When small aircraft X checked in he reported at 11,000, however, the strip indicated 12,000. I called cos approach and they advised that publication approach had changed the altitude, but failed to enter the information into the computer. Two approach controllers worked the aircraft, without forwarding the correct altitude via computer or to me via landline. This is a violation of handbook 7110.65.

Original NASA ASRS Text

Title: FAILURE TO INTERFAC COORD NEW ALT ASSIGNMENT. OPERATIONAL DEVIATION.

Narrative: SMA X, ROW-COS-IOC-FNL, ROUTE OF FLT. I TOOK AN AUTOMATED HANDOFF FROM COS APCH. WHEN SMA X CHECKED IN HE REPORTED AT 11,000, HOWEVER, THE STRIP INDICATED 12,000. I CALLED COS APCH AND THEY ADVISED THAT PUB APCH HAD CHANGED THE ALT, BUT FAILED TO ENTER THE INFO INTO THE COMPUTER. TWO APCH CTLRS WORKED THE ACFT, WITHOUT FORWARDING THE CORRECT ALT VIA COMPUTER OR TO ME VIA LANDLINE. THIS IS A VIOLATION OF HANDBOOK 7110.65.
