Narrative:

I went out on a gate call for the aft attendant jumpseat, it wouldn't spring back up. Another mechanic and I removed the seat while the aircraft was being boarded by passenger. Because we couldn't get off the plane, we called the lead on the radio, and gave him the part number off the removed seat. The lead ordered the seat from stores at the hangar. Stores delivered the seat to the aircraft and handed it up through the aircraft entry door. As I filled out the parts tag and logbook I noticed the different dash number, but figured like the #2, #3, and #5 seats were interchangeable. I also thought the lead had looked it up in MPD25 before it was ordered. For that reason and the fact that the plane was going to be delayed, I never double-checked the part number.

Title: A B737-700 WAS DISPATCHED IN NON COMPLIANCE WITH THE INCORRECT AFT CABIN ATTENDANT SEAT INSTALLED.

Narrative: I WENT OUT ON A GATE CALL FOR THE AFT ATTENDANT JUMPSEAT, IT WOULDN'T SPRING BACK UP. ANOTHER MECH AND I REMOVED THE SEAT WHILE THE ACFT WAS BEING BOARDED BY PAX. BECAUSE WE COULDN'T GET OFF THE PLANE, WE CALLED THE LEAD ON THE RADIO, AND GAVE HIM THE PART NUMBER OFF THE REMOVED SEAT. THE LEAD ORDERED THE SEAT FROM STORES AT THE HANGAR. STORES DELIVERED THE SEAT TO THE ACFT AND HANDED IT UP THROUGH THE ACFT ENTRY DOOR. AS I FILLED OUT THE PARTS TAG AND LOGBOOK I NOTICED THE DIFFERENT DASH NUMBER, BUT FIGURED LIKE THE #2, #3, AND #5 SEATS WERE INTERCHANGEABLE. I ALSO THOUGHT THE LEAD HAD LOOKED IT UP IN MPD25 BEFORE IT WAS ORDERED. FOR THAT REASON AND THE FACT THAT THE PLANE WAS GOING TO BE DELAYED, I NEVER DOUBLE-CHKED THE PART NUMBER.
