East Africa’s aircraft boom meets a maintenance bottleneck
The new hangar doors at Ethiopian Airlines’ sprawling Addis Ababa maintenance base opened with a ceremony and a promise. Two bays large enough for widebodies, a fresh component repair shop, and a central warehouse—more than $150 million invested to keep the region’s aircraft flying. The carrier now counts eight hangars on site and says it is ready to take in more third-party work from around the continent.

It’s a significant bet on a region where travel demand is rising fast. And yet the scene also underscored an uncomfortable truth: the line for maintenance, parts and skilled hands is growing faster than capacity.
Demand gallops ahead of capacity
By one industry estimate, African airline traffic will jump from 98 million passengers this year to 113 million in 2025—a 15% leap in twelve months, according to the African Airlines Association (AFRAA). Globally, maintenance, repair and overhaul (MRO) spending passed $114 billion in 2024 and is forecast to reach $156 billion by 2035. This “super-cycle” is being pushed by older fleets staying in service longer, strong utilization, and stubborn supply chain friction. Engine overhaul shops, in particular, report turn times stretching to historic highs.
That delay has a knock-on effect most travelers never see. When engines wait months for parts, airline schedules thin, aircraft are parked, and revenue evaporates. On paper, a high season. In practice, a weekly puzzle of shifting assets and shrinking buffers.
Somali operators: every hour counts
Nowhere is the margin thinner than for airlines flying classic narrowbodies and turboprops on short, commercially vital routes. Somali carriers lean on 737 Classics, Dash-8s and Fokkers—the reliable workhorses that connect Mogadishu to Nairobi, Hargeisa and regional hubs. In that world, an Aircraft on Ground (AOG) event can cost from €10,000 to €150,000 per hour, depending on the aircraft, route and the scope of the disruption. Multiply those hours, and the cost of a single snag becomes the difference between a good month and a red one.
There is also a new regulatory backdrop. With the Mogadishu Flight Information Region (FIR) restored to Class A airspace, international partners are looking closely at operating standards in the corridor. Auditors are spending more time on safety reporting, reliability programs, and the completeness of maintenance records. Compliance is no longer a box-tick; it is a commercial advantage—or a roadblock.
Paperwork is power
One lesson increasingly shared in boardrooms from Addis to Entebbe: paperwork equals money. A robust Safety Management System (SMS), aligned with ICAO Annex 19, travels well. It lowers the cost of insurance, strengthens the case for financing and leases, and eases the path to codeshares. It also reduces nasty surprises when an aircraft finally reaches the hangar. Clean logbooks and a steady rhythm of corrective action closeout can shave days off heavy checks and help secure scarce slots in advance.
This is where the industry’s quieter revolution is happening—digitizing records, tightening reliability tracking, and building a culture where a snag is reported once, fixed once, and learned from. It is unglamorous work. But in grounded hours saved, it’s worth more than a new paint job.
The case for turboprops on thin routes
In East Africa’s patchwork of short sectors and medium-density city pairs, turboprops remain a lifeline. The ATR 72-600, for instance, can emit roughly 45% less CO₂ than a comparable regional jet on short-haul routes. That math isn’t only about climate; it’s about cash. Lower fuel burn creates a cushion—money that can be redirected into maintenance reserves, line-station tooling or recurrent training. For small carriers, that operational discipline is often the difference between growing a network and shrinking it.
Three moves airlines can make this quarter
- Run a 48-hour reliability and SMS gap check. Baseline your fleet against Annex 19 expectations: hazard reporting, safety assurance, training records, and corrective-action follow-through. Produce a short, prioritized punch list for the quality team. The payoff is fewer audit findings when you request MRO slots and a better risk profile for underwriters.
- Target the usual avionics culprits. Many AOG events stem from recurring, fixable issues. Focus on pitot-static leaks, RVSM validations, transponder and TCAS tests, VOR/ILS, radio altimeters, and EGPWS checks. Keep nav databases current monthly. Don’t neglect wiring inspections and small modification packages that cut nuisance write-ups. These are quick wins that convert directly into dispatch reliability.
- Hedge parts and shop time now. Identify the five line-replaceable units most likely to ground your fleet type this season and pre-position rotables or secure a pooling arrangement. For unavoidable heavy work—especially engines—reserve shop windows early and make sure documentation is complete and consistent. In today’s environment, clean records are as valuable as the slot itself.
Diaspora skills as a competitive edge
There is a human angle to all this. East Africa’s maintenance ecosystem is being quietly upgraded by diaspora engineers who cut their teeth in Canada, Europe or the Gulf and then bring that discipline home. Their familiarity with licensing regimes, from AME credentials to radio technical certifications, helps local operators navigate audits and accelerate approvals. The region could benefit from scaling that know-how: harmonized licensing, apprenticeships tied to real fleets, and line-maintenance training that meets both local and international standards.
In practical terms, that means aligning national authorities and operators around a shared target: reduce unplanned ground time by days per aircraft each quarter. A small goal, repeated across fleets, unlocks capacity without building a single new hangar.
What to watch next
Three variables will define East Africa’s maintenance picture over the next 12 months:
- Engine shop backlogs. If turn times shorten, capacity will loosen across the board. If they don’t, operators will be forced to stretch intervals, lease spare engines at painful rates, or trim schedules.
- Parts pipelines. The availability of rotables and avionics components—and the lead times for core items—will determine how many AOGs are measured in hours rather than days.
- Regulatory momentum. Continued vigilance under the restored Class A airspace in the Mogadishu FIR, along with progress on digital recordkeeping and SMS maturity, will shape everything from insurance pricing to the pace of new routes and partnerships.
The Addis expansion is a reminder that East Africa can build world-class capability. The harder question is whether the region can match that brick-and-mortar ambition with equally rigorous processes: clear documentation, predictable reliability programs, and proactive parts strategies. For carriers balancing thin margins and high expectations, it’s not a choice between safety and growth; it’s a sequence. Safety first, then growth that sticks.
As the high season approaches, the region’s airlines face a simple challenge with complicated answers: how many grounded hours can you remove before the holidays? In a market rising as quickly as this one, the answer may define who thrives, who survives—and who sits on the tarmac waiting for a part that won’t arrive until next month.
