IER MRO Starts Building AI-Enabled Engine Shop at Dubai South

Construction has started on a new narrowbody engine maintenance complex at Dubai South. IER MRO Industries has appointed Dubai-based design-and-build contractor Group AMANA as general contractor for MRO4, the first operational phase of its development at Mohammed Bin Rashid Aerospace Hub (MBRAH), next to Al Maktoum International Airport.

The company announced the appointment on 14 September. Bureau of Engineering Studies Consulting Engineers (BEST) is the project’s engineer and consultant.

What is being built

MRO4 is the fast-track first building of a wider 1.4 million sq ft site. IER says the complex is designed as a highly automated engine shop, combining engine and major-module repair and overhaul with AI-enabled operations, robotics, digital twin technology and advanced manufacturing.

At full scale, the company says the site will be able to handle up to 550 engine shop visits a year, or about 2,000 major module overhauls. The plan also includes a twin engine test cell facility designed for more than 1,000 tests a year, with room for engines of up to 100,000 lb of thrust. That ceiling is high enough for large widebody engines, not only the narrowbody types the shop is starting with.

Initial work will focus on the CFM56 and LEAP engine families. IER says it plans to expand later into advanced manufacturing, component engineering and other aftermarket services, along with a technical training academy and a centre of excellence on site.

Lawrence J. Howie, IER MRO’s chairman and CEO, said the company is aiming for a highly automated, AI-native operation rather than a conventional engine shop.

Why narrowbody engine capacity matters here

CFM56 and LEAP engines power a large share of the region’s narrowbody fleet, including flydubai’s Boeing 737s (CFM56-7B and LEAP-1B) and Air Arabia’s LEAP-1A-powered A320neo family aircraft. Limited shop capacity is one of the factors that industry forecasts cite behind rising global MRO spending, and long engine turnaround times keep aircraft on the ground.

Engine shop capacity is also where the region is investing most heavily. In May, Sanad announced an AED480 million engine repair centre in Al Ain covering Trent 700, V2500, LEAP, GEnx and GTF parts. In the same month Emirates broke ground on a US$5.1 billion engineering complex at Dubai South, due by mid-2030. IER’s project adds an independent, narrowbody-focused shop to that mix, at the same airport cluster where Emirates is building.

The test cell is a notable part of the plan. An overhauled engine has to pass a test run before it is released back to service, so every engine shop depends on access to a cell. A twin-cell facility rated to 100,000 lb would give operators in the UAE another local option for that final step.

What to watch

IER has not given a capacity figure for MRO4 on its own, and the 550 shop-visit figure refers to the complex at full scale. Key milestones will be the opening of the first building, regulatory approvals for the shop, and which airlines and lessors sign up as its first customers.
