Delta Air Lines places order for 100 A321neo ACF aircraft

Delta launches first-ever service from Los Angeles to Auckland

Atlanta, Georgia (U.S.) 14 December 2017 – Delta Air Lines today placed an order with Airbus for 100 of the manufacturer’s modern A321neo ACF (Airbus Cabin Flex configuration) aircraft. The U.S.-based carrier selected the largest member of Airbus’ single-aisle Family to meet Delta’s future requirements for aircraft with greater efficiency and additional capacity. The airline’s A321neo ACF planes will be powered by Pratt & Whitney PW1133G-JM geared turbofan engines.

Delta’s announcement on the A321neo ACF follows several orders in recent years for the current engine option (ceo) version of the A321. Delta has ordered a total of 117 A321ceos, each powered by CFM56 engines from CFM International.

The A321neo ACF introduces new door and fuselage enhancements allows airlines to make best use of the cabin space with a range of up to 4,000 nautical miles. The A321 is the largest member of the A320 Family, seating up to 240 passengers. Incorporating the latest engines, aerodynamic advances, and cabin innovations, the A321neo will offer a significant reduction in fuel consumption of 20 percent by 2020. With more than 5,300 orders received from 96 customers since its launch in 2010, the A320neo Family has captured some 60 percent share of the market.

Most of Delta’s A321neos will be delivered from the Airbus U.S. Manufacturing Facility in Mobile, Alabama. The airline has taken delivery of 13 U.S.-manufactured Airbus aircraft since last year. In addition, the 50^th aircraft to be produced by the Airbus U.S. Manufacturing Facility will be delivered to Delta later this week. The Mobile factory produces four aircraft per month for delivery to Airbus’ U.S. customers. Plans for further production ramp up are currently being discussed.

In addition to Airbus’ U.S. manufacturing, the company has a long and strong partnership with American aerospace supplier companies. Today, there is more U.S. content in Airbus aircraft than from any other country, with more than 40% of the company’s aircraft-related procurement coming from the United States.

As of the end of November, Delta was flying a fleet of 196 Airbus aircraft, including 150 A320 Family members, 42 A330 widebodies, and four A350 XWB aircraft

Lost Tool Found in Qantas A380 After 34 Flights

An Australian Transportation Safety Bureau (ATSB) investigation recently revealed that a Qantas A380 operated 34 flights with a 1.25-meter nylon tool lodged in one of its engines.

This turning tool, used during borescope inspections to rotate the intermediate-pressure compressor, was left behind during scheduled maintenance at Los Angeles on December 6, 2023. It remained inside the engine until it was discovered by maintenance staff during a subsequent check at Los Angeles on January 1, 2024.

The ATSB report highlights two critical lapses. First, maintenance engineers failed to notice the tool during final checks for foreign objects after the borescope inspection. Second, the lost tool procedure was not activated when the tool was identified as missing.

The certifying engineer ultimately cleared the aircraft for service without accounting for the misplaced tool. During the time qantas films the tool was inside, the A380 completed 34 flight cycles, accumulating nearly 294 hours without any noticeable effect on engine performance.

Although the tool was deformed by high-energy airflow within the engine, there was no reported damage to the engine itself. ATSB Chief Commissioner Angus Mitchell commented.

“This incident underscores the importance of following established maintenance protocols. Engineers missed the tool during foreign object checks, and the required lost tool procedure wasn’t started after realizing the tool was missing.”

Following the investigation, the airline issued a safety directive, urging all engineering and tool storage teams to adhere strictly to these protocols to prevent similar incidents in the future.

A qantas spokesperson stated, “While the tool didn’t impact engine performance, we take this incident very seriously. It is critical to follow the correct lost tool procedures.”
