Technical Operations Center

Delta’s primary maintenance facility, the Technical Operations Center (TOC), is located at Hartsfield-Jackson International Airport in Atlanta.
The TOC consists of three interconnected buildings or hangars that cover 63 acres or nearly 2.7 million square feet.

TOC-1 can accommodate up to two wide-body aircraft and four narrow-body aircraft simultaneously. It also houses TechOps’ five engine test cells.

Before an engine goes back into service, it is put through the rigors of TechOps’ engine test cells.
The average test runs about 16 hours (32 man hours) and is more rigorous than anything the engine would experience on an aircraft.
Annually, more than 650 engines and 350 APUs are tested in one of our five test cells.
The largest cells are capable of testing engines providing up to 100,000 pounds of thrust.
The facility uses 85,000 gallons of fuel a month to keep with its rigorous 24-hour, 7-day a week schedule.

TOC-2, the larger hangar, is one of the world’s largest cantilevered buildings. It accommodates six widebody aircraft and six or more smaller aircraft simultaneously.
TOC-3 provides four floors of shops and warehouses and three state-of-the-art paint hangar bays that can simultaneously accommodate two widebody aircraft and one narrowbody aircraft.

Average time to strip and paint a narrowbody aircraft is five days, and approximately six days for a widebody aircraft.
A narrowbody needs 40 gallons of paint (including primers) to repaint the exterior, while a widebody needs 80 gallons.
