Frequently Asked Questions
Why is Dubai a strong location for an aircraft engine repair and overhaul business
Dubai sits at the intersection of major aviation routes connecting Europe, Africa, South Asia, and Central Asia. Its airports — Dubai International and Al Maktoum International — serve as operational hubs for Emirates, flydubai, and hundreds of international carriers, generating consistent MRO demand from large commercial fleets.
The emirate's logistics infrastructure further strengthens the case. Al Maktoum International Airport's cargo facilities, DP World's bonded warehousing, and established customs corridors allow efficient parts import, repair, and re-export — a critical advantage in engine shop work where component turnaround time directly affects commercial competitiveness.
The UAE aviation sector contributes approximately 15% of Dubai's GDP, according to the Invest in Dubai portal, and the Middle East MRO market is projected to grow at a robust CAGR through 2030, driven by fleet expansion and ageing aircraft cycles.
What does activity code 3315.92 cover for aircraft engine businesses in Dubai
Activity code 3315.92 — Aircraft Engine & Parts Repair & Overhaul — covers the technical restoration, testing, and airworthiness certification of aircraft engines and their components. This includes complete engine overhaul (disassembly, inspection, repair, and reassembly), component repair, and parts testing against manufacturer specifications.
The licence also covers the documentation required to return parts to serviceable condition. Importantly, it addresses engine shop and base maintenance work, not line maintenance carried out on the apron — a distinction that affects facility planning, staffing levels, and the regulatory approvals you will need to obtain.
Typical customers under this activity code include commercial airlines, cargo operators, helicopter fleet owners, private jet operators, and defence contractors, each with different contract and billing structures.
What regulatory approvals are required beyond a trade licence to operate an MRO business in the UAE
A trade licence from a free zone such as Meydan Free Zone establishes your legal entity and commercial standing, but it does not authorise you to carry out regulated aircraft maintenance work. A separate MRO organisation approval from the General Civil Aviation Authority (GCAA) — the UAE's primary aviation regulator — is mandatory before you can perform maintenance on civil aircraft.
International airline customers will additionally require EASA Part-145 or FAA Part-145 certification, depending on the aircraft types in their fleets. These certifications involve formal audits, facility inspections, and qualified personnel requirements and run in parallel with your commercial setup rather than after it.
Planning for both the GCAA approval process and international certifications from the outset is essential to avoid delays in becoming commercially operational.
What types of customers does an aircraft engine overhaul business in Dubai typically serve
The customer base spans several distinct aviation segments. Commercial airlines — including major carriers like Emirates and flydubai — typically operate on long-term MRO agreements with defined turnaround times and pricing schedules. Cargo operators follow similar structured contracting models.
Private jet and helicopter operators often work on time-and-material billing rather than long-term agreements, offering more flexible but potentially less predictable revenue. Defence contractors represent another segment with specific compliance and security requirements.
Parts supply — sourcing, testing, and reselling serviceable components — can add an additional margin layer to the core repair revenue model across all customer segments.
How does UAE VAT treatment apply to aircraft engine repair and overhaul services
The UAE applies VAT zero-rating to qualifying international aviation services under rules set by the Federal Tax Authority. This means that certain engine repair and overhaul services provided in connection with international air transport may be zero-rated rather than subject to the standard 5% VAT rate.
The specific conditions for zero-rating depend on the nature of the service, the aircraft involved, and the operator's status. Businesses should obtain formal tax advice and review Federal Tax Authority guidance to confirm which of their services qualify, as misclassification carries compliance risk.
Proper VAT structuring is particularly important when dealing with international airline customers, who will have their own tax compliance requirements and may scrutinise invoicing closely.
What role does Al Maktoum International Airport play in MRO operations
Al Maktoum International Airport is designed to become the world's largest airport by capacity and already offers substantial cargo infrastructure relevant to MRO operators. Its facilities support the efficient movement of aircraft engines and components, which are often large, heavy, and subject to strict handling requirements.
For engine overhaul businesses, proximity to Al Maktoum's cargo terminals reduces inbound and outbound logistics time for engines and parts. Combined with DP World's bonded warehousing options, operators can hold imported components in customs-efficient storage while work is scheduled, improving cash flow and turnaround management.
The airport's growth trajectory also signals long-term increases in aircraft movements through the region, which translates directly into sustained MRO demand for businesses established in Dubai.
What is driving MRO market growth in the Middle East
Fleet expansion is the primary driver. Emirates operates more than 250 widebody aircraft, each requiring scheduled engine shop visits, while Air Arabia and flydubai continue adding narrowbody aircraft to their fleets. Private aviation and helicopter operations contribute additional volume beyond commercial airline demand.
Ageing aircraft cycles are a secondary driver. As regional fleets mature, the frequency and complexity of engine overhaul requirements increase, supporting sustained workshop throughput even without new aircraft deliveries.
According to IMARC Group, the Middle East MRO market is on a consistent growth trajectory underpinned by these fleet dynamics and the region's role as a transit hub for Africa, South Asia, and Central Asia routes — all of which generate ongoing maintenance demand.
What is the difference between base maintenance and line maintenance for licensing purposes
Base maintenance refers to scheduled, in-depth work carried out in a hangar or workshop environment — including engine overhaul, heavy checks, and component restoration. Activity code 3315.92 and the associated GCAA approvals are oriented toward this type of work, which requires dedicated facilities, specialised tooling, and certified technical staff.
Line maintenance refers to routine checks and minor repairs carried out on the aircraft apron between flights, typically to keep an aircraft serviceable for its next departure. This activity falls under a different regulatory and licensing framework.
The distinction matters practically because facility requirements, staffing qualifications, and regulatory approval pathways differ significantly between the two. Businesses planning engine shop operations should ensure their facility design and approval applications are aligned with base maintenance standards from the outset.
How to Start an Aircraft Engine Repair and Overhaul Business in Dubai
Dubai sits in one of the busiest air corridors in the world. Emirates and flydubai are based here, hundreds of international carriers pass through Dubai International and Al Maktoum International, and all those aircraft need engines that work. That is steady, well-paid work for anyone who can do it properly.
This is not a business you start on a laptop. You need a workshop, certified engineers, and approval from the aviation regulator before you touch a civil aircraft. But the demand is real and it is not going away. This guide covers what activity code 3315.92 allows, who buys the work, and how to get set up through Meydan Free Zone.
Key Stats at a Glance
What This License Covers
Activity code 3315.92 covers repair and overhaul of aircraft engines and their parts. In plain terms, that means:
- Full engine overhaul: strip it down, inspect it, repair it, put it back together
- Component repair on individual parts
- Testing parts against the manufacturer's specifications
- Producing the paperwork that returns a part to serviceable condition
One distinction matters more than any other here. This license is for engine shop and base maintenance, the deep work done in a hangar or workshop. It is not for line maintenance, the quick checks and small fixes done on the apron between flights, which sits under a different framework. Get this right early, because it decides your facility, your staffing and which approvals you apply for.
Who Your Clients Will Be
Nobody in this market buys on a phone call. Contracts are formal, audited and slow to win, and that is good news once you are in.
Your customers are:
- Commercial airlines, usually on long-term agreements with fixed turnaround times and pricing
- Cargo operators, who contract in much the same way
- Private jet and helicopter operators, who tend to pay time and materials rather than sign long contracts
- Defence contractors, who bring their own compliance and security conditions
There is a second income line worth planning for. Sourcing, testing and reselling serviceable components adds margin on top of the repair work itself, and it uses capability you already have.
Mainland or Free Zone
For an operation with heavy capital equipment, the free zone route usually wins on duty alone. Whichever you choose, the GCAA approval is the same requirement and the same timeline.

Step by Step Setup Guide
- Step 1, book your trade name: Submit the name you want and have it checked against UAE naming rules.
- Step 2, confirm your activity: Code 3315.92 is the right one. Check the exact scope with the Meydan Free Zone team so everything you plan to offer is covered, and add any related activities now.
- Step 3, send your shareholder documents: Passport copies for all shareholders and directors, a shareholder resolution if a company holds shares, and a summary business plan covering your services and target customers.
- Step 4, get your license: Pay the fees and the trade license is issued, usually in days rather than weeks.
- Step 5, sort your visas: Investor and employee quotas depend on the package you choose.
- Step 6, arrange your facility: Your workshop, hangar or engine bay is leased separately and runs alongside the license, not after it.
You will also need a No Objection Certificate if you currently hold a UAE residence visa under another sponsor, plus evidence of your technical qualifications or existing MRO certifications. Corporate shareholders need attested company documents.
Compliance and What You Need in Place
GCAA approval
Your trade license makes the company legal. It does not let you work on aircraft. The General Civil Aviation Authority issues MRO organisation approvals, and you need one before you touch a civil aircraft. Start this early, because it takes far longer than the license.
International certification
Airline customers will want EASA Part-145 or FAA Part-145 approval, depending on what they fly. Both mean audits, facility inspections and qualified staff. Run them alongside your commercial setup rather than treating them as a later step.
Staff
Every maintenance engineer must hold a license the GCAA recognises. Licensed Aircraft Maintenance Engineers with type ratings on the engines that matter commercially are scarce across the region, so budget properly for pay and allow real time to recruit. MOHRE rules apply too, including Emiratisation thresholds for technical workshops.
Customs
Parts brought in for repair and sent back out get bonded treatment. The Ports, Customs and Free Zone Corporation framework covers bonded warehousing and re-export, which also helps your cash flow while work is scheduled.
VAT
The Federal Tax Authority zero-rates qualifying services tied to international air transport. Whether yours qualify depends on the service, the aircraft and the operator, so get formal tax advice. Airline customers check invoices closely.
Insurance
Aviation liability cover is not optional. It is a condition of GCAA approval and commercial operators will ask for it. Talk to a specialist aviation insurer before you are mid-negotiation on a contract.
Market Opportunity
Fleet size is what drives this. Emirates alone runs more than 250 widebody aircraft, every one of them due engine shop visits on a schedule. Air Arabia and flydubai keep adding narrowbody aircraft, and private and helicopter operations add more on top. As those fleets age, overhauls get more frequent and more involved, which keeps a workshop busy even in years with few new deliveries.
IMARC Group has the Middle East MRO market on a steady growth path through 2030. Around that sits the logistics: cargo facilities at Al Maktoum International, bonded warehousing from DP World, and customs routes that let parts come in, get worked on and go back out quickly. In engine work, turnaround time is what you compete on.
Conclusion
This is a high-barrier sector, and that is the point. Capital, certification and skilled people keep the field small, and Dubai gives you fleet density, logistics and a favourable tax and ownership structure that most places in the region cannot match.
Three things decide whether it works: enough capital at the start, qualified engineers you can actually hire, and the right order of trade license, GCAA approval and international certification. Undercapitalising is the most common way these ventures fail, so be honest about the numbers before you begin.
