Why Nigerian Airlines Still Send Aircraft Abroad For Heavy Maintenance

Nigeria’s aviation industry has a problem that extends far beyond the runway. Each time a Nigerian-registered aircraft leaves the country for a heavy maintenance check, the airline is not only paying for engineering work abroad; it is also paying for ferry flights, foreign accommodation and logistics, imported technical expertise and, most importantly, scarce foreign exchange.

The practice has persisted for years because Nigeria has not developed enough local Maintenance, Repair and Overhaul (MRO) capacity to handle the full range of heavy checks required by modern commercial aircraft. Although some Nigerian facilities can perform important maintenance work, the industry still relies heavily on overseas centres for major C-checks and more extensive structural overhauls.

The result is a recurring cycle: aircraft leave Nigeria, dollars leave with them, airlines lose revenue while the aircraft is out of service, and Nigerian engineers and MRO companies lose opportunities to deepen their capabilities.

Why aircraft leave Nigeria for heavy maintenance

Aircraft maintenance is divided into different levels, depending on the complexity and frequency of the inspection. Routine checks can be performed relatively quickly, while heavy maintenance requires aircraft to be opened up extensively, with engineers examining structural components, systems, wiring, landing gear, avionics and other critical areas.

C-checks are among the major scheduled maintenance events for commercial aircraft. Their frequency depends on the aircraft type and the manufacturer’s maintenance programme, but they can occur roughly every 18 to 24 months or according to the approved maintenance schedule.

D-check is traditionally used to describe the most comprehensive form of aircraft overhaul, although modern maintenance programmes increasingly use different terminology and task-based schedules. Such heavy maintenance can require extensive disassembly and structural inspection and may keep an aircraft out of commercial service for weeks or longer.

For an airline, the decision about where to conduct such work is therefore not simply about finding the cheapest workshop. The facility must have the right approvals, tooling, trained personnel, technical data, spare-parts access and capacity for the particular aircraft type.

The Nigeria Civil Aviation Authority (NCAA) requires organisations maintaining Nigerian-registered aircraft to operate within an approved regulatory framework. The regulator says it issues Approved Maintenance Organisation (AMO) certificates to organisations seeking to maintain Nigerian-registered aircraft, while foreign maintenance organisations can also be approved or accepted under applicable regulatory arrangements.

That regulatory requirement is important because aircraft maintenance is fundamentally a safety issue. An airline cannot simply choose a cheaper workshop without considering whether the facility is appropriately certified and capable of performing the required work.

The economics behind the decision

The financial burden becomes clearer when the cost of a C-check is converted into naira.

Industry estimates have varied considerably depending on aircraft type, age, the scope of the inspection and parts that must be replaced. BusinessDay reported in 2024 that a routine 1C check on a Boeing 737 could cost between $180,000 and $250,000, while 2C and 4C checks could rise to approximately $250,000-$300,000 and $500,000-$600,000 respectively. The same report noted that unexpected corrosion, cracks or other findings can substantially increase the final bill.

Other industry estimates have placed a typical C-check at between $500,000 and $1 million or more, depending on the aircraft and work required.

The headline price, however, is only part of the calculation when the aircraft is sent overseas.

There is the cost of flying or ferrying the aircraft to the maintenance destination. There are also parking, handling and administrative charges, as well as logistics associated with personnel, spare parts and returning the aircraft to Nigeria.

A 2018 BusinessDay report estimated that an overseas C-check on a Boeing 737 could cost up to $800,000 before ferrying and other expenses added more than $200,000 to the bill.

For airlines operating on thin margins, these additional costs matter.

The aircraft is also unavailable for revenue-generating flights while it is undergoing maintenance. If an airline has a small fleet, taking one aircraft out of service can immediately affect its schedule and available capacity.

This creates an uncomfortable contradiction for Nigerian carriers. They need heavy maintenance to keep aircraft airworthy, but the maintenance process itself can weaken their cash flow.

The foreign-exchange problem

The biggest macroeconomic concern is foreign exchange.

Nigerian airlines earn a large portion of their domestic revenue in naira, while many of their major obligations including aircraft leases, insurance, spare parts and overseas maintenance are dollar-denominated.

When the naira weakens, an aircraft maintenance invoice that was already expensive in dollars becomes significantly more expensive in local currency.

BusinessDay reported that, at an exchange rate above ₦1,500 to the dollar, a Boeing 737 C-check in the range of $500,000-$1 million could translate into hundreds of millions of naira and potentially more than ₦1 billion depending on the scope of work.

The problem is not restricted to individual airlines. Collectively, the money represents capital leaving the Nigerian economy for services that could potentially be provided domestically if sufficient capacity existed.

Recent industry estimates have put annual overseas maintenance expenditure by Nigerian airlines at around $1 billion, while a 2025 Leadership report estimated that local airlines spent about $5 billion on aircraft maintenance abroad over five years. Such figures vary according to the aircraft population and the categories of maintenance included, but they illustrate the scale of the potential market.

For an economy struggling to conserve foreign exchange, retaining even a substantial portion of that expenditure domestically could have implications beyond aviation.

Nigeria already has part of the answer

The picture is not that Nigeria has no MRO capability.

Aero Contractors operates an MRO facility, while 7Star Global Hangar and other operators have developed local maintenance capabilities. In 2024, Aero Contractors said the combination of foreign-exchange pressures and changing market conditions had resulted in increased demand for its facility, with its hangars becoming heavily occupied.

The experience demonstrates that Nigerian operators can perform significant maintenance work when the infrastructure, approvals and technical resources are available.

The challenge is scale.

A facility may be capable of maintaining one aircraft type but unable to handle the full range of aircraft operated by Nigerian carriers. Another may have skilled personnel but lack specialised tooling or sufficient hangar space. Yet another may have the infrastructure but struggle to secure the investment needed to expand its approvals and capabilities.

The industry therefore needs more than a single hangar.

It needs an ecosystem.

That means specialist workshops, component repair, engine support, avionics capability, spare-parts logistics, technical training, tooling, engineering support and certification capacity working together.

Why airlines may still prefer foreign facilities

There is also a business argument behind the continued use of overseas MRO centres.

International maintenance companies have spent decades building large facilities around major aviation markets. They often serve multiple airlines and aircraft types, allowing them to spread infrastructure costs across a much larger customer base.

For an airline, sending an aircraft to an established international MRO may offer access to specialised equipment, experienced personnel, manufacturer relationships and predictable maintenance processes.

Reliability is particularly important. A cheaper maintenance check that keeps an aircraft grounded for an extra month can ultimately cost more than a more expensive check completed within the planned timeframe.

This is why simply telling Nigerian airlines to “maintain aircraft locally” will not solve the problem.

Local MRO facilities must demonstrate international standards, competitive pricing, turnaround times and technical reliability.

Nigeria’s regulator already has a framework for approving maintenance organisations. The NCAA notes that international aviation rules allow maintenance to be performed by approved organisations in the State of Registry or another contracting state, subject to the relevant approval and acceptance requirements.

The opportunity, therefore, is to make Nigerian facilities competitive enough that airlines choose them because they make commercial sense not simply because government directs them to.

What a strong MRO industry could change

A functioning Nigerian MRO ecosystem could retain significant foreign exchange within the country.

Instead of paying a foreign facility for labour, hangar space and engineering services, an airline could spend a larger proportion of its maintenance budget with Nigerian companies.

The economic benefits would extend beyond the airlines.

A growing MRO industry would require engineers, aircraft technicians, electricians, avionics specialists, welders, mechanics, inspectors, planners and other technical professionals.

It would also create demand for local suppliers, logistics companies, accommodation providers and aviation training institutions.

Nigeria could eventually position itself as an MRO hub for West and Central Africa, serving aircraft from neighbouring countries rather than competing only for Nigerian aircraft.

That regional opportunity is significant. An MRO facility does not have to depend exclusively on domestic airlines to remain viable. If properly certified and competitively operated, it can attract aircraft from across the region.

There are already indications that Nigerian facilities can serve beyond the domestic market. BusinessDay reported that Aero Contractors had received approval from the Ghana Civil Aviation Authority to conduct checks on Ghanaian aircraft.

Investment is the missing link

Building a world-class MRO facility requires substantial capital.

The infrastructure is expensive. So are aircraft jacks, tooling, ground-support equipment, specialist diagnostic systems and component repair equipment.

But investment cannot stop at construction.

The industry needs sustained spending on certification, training and technology. Engineers must be exposed to changing aircraft technologies, while facilities must maintain access to updated technical manuals and approved data.

Government can help by creating an environment in which private investors can commit capital for the long term.

That could include infrastructure support, reliable power, improved airport facilities, streamlined regulatory processes, investment incentives and policies that encourage airlines to patronise qualified local MRO providers.

The objective should not be to shield inefficient operators from competition. Rather, it should be to reduce the structural disadvantages that make local aviation businesses more expensive or less predictable than overseas alternatives.

A new MRO push

The debate has gained fresh momentum with new proposals for major MRO investments.

In August 2026, Binani Global Air Services announced plans to develop an MRO facility in Abuja and said the project was targeting about $218 million in annual foreign-exchange retention. The company said the facility was intended to reduce Nigerian airlines’ dependence on overseas centres for heavy checks.

Such projects could become important if they move successfully from announcements to operational facilities with the necessary approvals and technical capabilities.

The larger lesson, however, is that Nigeria does not merely need another hangar. It needs a sustainable maintenance industry.

The country has spent decades watching aircraft leave its airports for heavy maintenance abroad. Every departure represents a safety requirement, but it also represents a commercial opportunity that Nigeria has historically struggled to capture.

The answer is not to compromise on safety or regulatory standards in the name of retaining dollars. Nor is it to force airlines into facilities that cannot meet their technical requirements.

The answer is to build facilities capable of competing.

For Nigerian airlines, local heavy maintenance could mean lower exposure to exchange-rate volatility, reduced ferrying costs, shorter logistics chains and potentially faster access to technical support.

For the Nigerian economy, it could mean fewer dollars leaving the country, new technical jobs, stronger aviation skills and the development of an industry capable of servicing aircraft across West Africa.

The irony is that Nigeria has already demonstrated that local aircraft maintenance is possible. What remains is to build enough capacity, at the right technical standard and on a scale large enough to turn isolated success stories into an industry.

Until that happens, Nigerian airlines will continue to face the same dilemma: operate aircraft in a market where revenues are largely earned in naira, while sending some of their most expensive maintenance obligations abroad in dollars.

And each time an aircraft crosses the border for a major check, Nigeria loses more than the opportunity to repair an aircraft at home. It loses another opportunity to build the aviation industrial base it has spent years trying to create.
