South Asian commercial fleets have expanded steadily for well over a decade, driven by rising discretionary travel, low-cost carrier penetration and route growth into the Gulf and South-East Asia. Regional maintenance, repair and overhaul capacity has not expanded at the same rate. The result is a structural gap that has been widening long enough that it can no longer be described as a temporary imbalance.
The shape of the gap
Aircraft maintenance divides into work that must happen where the aircraft operates and work that can happen anywhere. Line maintenance — turnaround checks, defect rectification, minor scheduled tasks — is performed at base and is generally available wherever a carrier operates. Base maintenance is different. Heavy checks take an aircraft out of service for weeks, require hangar capacity, tooling and certified staff, and are economically indifferent to geography beyond ferry cost.
It is the second category where the regional gap sits. Component overhaul, landing gear, engine shop visits and heavy airframe checks are concentrated in a small number of established hubs, principally in South-East Asia, China and the Gulf. Carriers based in South Asia therefore ferry aircraft out of the region, pay for positioning flights, accept longer turnaround times and hold more spare capacity than they would otherwise need.
Every one of those is a cost that a regionally located facility could capture. The gap is not a lack of demand for maintenance. It is a mismatch between where the fleets are and where the hangars are.
Why capacity has not followed the fleet
Because MRO is a harder business than it looks. It is capital-intensive in a way that is unforgiving: a hangar, tooling and a component store must exist before the first check is sold. It is skills-intensive, and licensed engineers take years to qualify and are internationally mobile the moment they are. It is approvals-intensive, since a facility is only commercially useful for the aircraft types and the regulatory jurisdictions it is certified for. And it is contract-dependent: the economics require a base load of committed volume before the facility opens, not after.
Those four conditions have to be met simultaneously. Meeting three of them produces a facility that cannot fill its hangar. That is why the gap persists in a market that would appear, on demand alone, to have closed it years ago.
The approvals foundation
A maintenance organisation is approved by the civil aviation authority of the state in which it operates, and separately by the authorities of the states whose registered aircraft it wishes to work on. In Bangladesh the domestic approval sits with the Civil Aviation Authority of Bangladesh. International recognition — the approvals that allow a facility to serve foreign-registered fleets — is what converts a domestic capability into an export business.
This is why regulatory standing at the national level matters commercially and not merely administratively. A country whose oversight system is well regarded internationally can host facilities that sell to the region. A country whose oversight system is under scrutiny cannot, regardless of the quality of any individual hangar. Any serious investment case in this sector has to underwrite the trajectory of the national regulatory position alongside the trajectory of the market.
Where the Bangladeshi case is strongest
Three arguments carry weight. The first is labour: a large technical workforce, an established culture of vocational training, and a cost base that compares favourably with the incumbent hubs. Certified engineering capability is created rather than found in any market, and Bangladesh has the raw input in depth.
The second is geography. The country sits between two very large aviation markets and on routes that already carry substantial traffic. Ferry cost from a Bangladeshi facility to much of the region is modest.
The third is that terminal and airfield investment has already been made. Where apron, taxiway and terminal capacity is being expanded, the marginal cost of adding maintenance infrastructure is far lower than building it standalone, and the case for anchoring an aviation cluster is easier to make while that programme is live.
The most credible entry route is a joint venture pairing an established MRO operator — which brings type approvals, process maturity, customer relationships and, critically, an existing order book — with local capital, land and workforce. Very few markets have built independent MRO capability from a standing start. Most have imported the operating capability and built the market around it.
What would have to be true
A facility needs anchor volume committed before construction, from a carrier or group of carriers with a real fleet plan. It needs type approvals that match the regional fleet rather than the sponsor’s preference. It needs a training pipeline established at the same time as the hangar, not after it. It needs the national regulatory position to be stable and improving. And it needs a customs regime that allows spares and rotables to move in and out without becoming the constraint on turnaround time — a detail that decides more MRO business cases than any other single factor.
The demand case for regional MRO capacity is not seriously contested. What determines whether a specific facility succeeds is whether those five conditions were arranged before the first aircraft arrived.
