- Nepal Airlines returned one Airbus A330 to Kathmandu on August 6, 2026, after maintenance in Italy.
- The carrier faces severe grounding risks with only two widebody aircraft available for long-haul routes.
- Future maintenance costs are estimated at Rs 5 billion as aircraft approach major flight cycle thresholds.
Nepal Airlines brought one Airbus A330 back to Kathmandu on August 6, 2026, after it completed a fourth C-check in Italy, but a conflicting maintenance timeline still leaves the carrier exposed to a possible grounding of its remaining widebody capacity.
The airline operates only two A330-200s for long-haul services. Its other two aircraft are A320s, used on regional and shorter international routes.
One account says 9N-ALY, identified there as Annapurna, left for Naples on July 7, 2026, and missed an expected August 2, 2026, return. Another identifies Annapurna as the aircraft that completed its fourth C-check and reached Kathmandu on August 6. The accounts do not align.
The status of the second A330 now carries the immediate operational risk. Nepal Airlines has no spare widebody aircraft to cover a prolonged maintenance absence. One aircraft is enough to remove half of its long-haul capacity.
Ramesh Paudel, a Nepal Airlines spokesperson, said the carrier would try to preserve scheduled services while accepting that maintenance problems could cause delays.
“Flights will be delayed when the aeroplane are grounded; we have planned to avoid canceling the scheduled flight as much as possible.”
The disruption has already touched services linking Kathmandu with Dubai, Dammam and Narita. Schedule cuts or aircraft substitutions could follow if the remaining maintenance work runs late.
The aircraft information points to a maintenance timeline under strain
The available aircraft details combine a confirmed return with an unresolved account of the earlier check. The registrations, names and cycle figures are presented below without treating the conflicting timeline as settled.
| Registration | Name identified in the material | Maintenance and operational detail | Cycles remaining |
|---|---|---|---|
| 9N-ALY | Annapurna in one account | Completed its fourth C-check and returned to Kathmandu on August 6, 2026; another account places it in Naples after July 7 and delayed beyond August 2 | Roughly 500 |
| 9N-ALZ | Makalu in one account | The remaining maintenance slot is the focus of the current delay risk | Roughly 400 |
The conflicting aircraft names should not be used to infer that both jets remain overseas. The August 6 return is the clearest current status supplied for either aircraft.
The operational problem is straightforward. Heavy maintenance can keep an aircraft out of service until technicians complete the work and clear it for flights. With only two widebodies, Nepal Airlines has little room to absorb another delay.
An A330 can operate for as many as 18–20 hours daily, yet the carrier has recently averaged about eight hours per day. Technical problems and a shortage of destinations have held utilization to 40%.
Archana Khadka, identified as a former or alternative Nepal Airlines spokesperson, said more destinations would be needed to use the aircraft more intensively.
“Operating an aircraft at full daily capacity means adding new destinations. if we could add South Korea alone, the A330 could be flown up to 15 hours a day.”
The airline’s limited reserve capacity has already produced passenger disruption. In May 2026, the simultaneous grounding of both widebodies left approximately 1,500 passengers stranded.
The Kathmandu-Narita service is used mainly by Nepali students and migrant workers. Delays of 24–48 hours have put university reporting deadlines at risk and threatened to push some travelers toward visa expirations.
Passengers have also faced premium prices when switching to foreign carriers such as Qatar Airways or Emirates. Nepal Airlines’ fleet has no widebody backup when both aircraft are unavailable.
The next overhaul could cost Rs 5 billion
Both A330s are approaching a regulatory threshold of 6,000 flight cycles, which requires a full overhaul. The material assigns roughly 400 cycles to 9N-ALZ and 500 to 9N-ALY.
Nepal Airlines has estimated a global tender for overhauling both aircraft at Rs 5 billion (approx. USD 34.5 million). That figure covers the planned work, not a confirmed replacement aircraft or the cost of every schedule disruption.
Devendra Pun, the airline’s technical spokesperson, said management was considering leased engines rather than leasing a complete aircraft.
“We are at a critical stage for initiating the overhaul process. We have chosen to lease engines rather than lease an entire aircraft.”
The plan addresses equipment needs but does not remove the exposure created by an aircraft held in maintenance. The two A320s cannot provide equivalent widebody capacity on the carrier’s long-haul network.
Earlier delays have already affected the airline’s finances. The two aircraft spent 163 total days inactive two years ago, producing what officials described as “massive revenue losses” estimated in the millions of dollars.
The maintenance cycle is therefore approaching from two directions: an immediate need to complete scheduled work and a longer-term requirement to overhaul aircraft nearing their cycle limit.
A repeat contract has reopened questions about procurement
The latest maintenance concerns follow Nepal Airlines’ decision to use the Italian provider Atitech SpA again. Two years earlier, the carrier sent the same aircraft there for a check planned to last 30 days.
The work lasted longer. One aircraft remained unavailable for 80 days, while the other stayed out of service for 83 days.
A government-led investigation examined those delays. Triratna Manandhar, a former director general of the Civil Aviation Authority of Nepal and head of the committee, called the procurement process “flawed and non-transparent.” The committee recommended that the airline not return to the provider without corrective measures.
Nepal Airlines nevertheless signed a new contract with Atitech in July 2026. The new maintenance timeline has revived the earlier concerns, although the supplied accounts differ over which aircraft was delayed and when it returned.
The A330 program is also connected to a Rs 1.47 billion corruption case filed by the Commission for Investigation of Abuse of Authority in April 2024. The case names 32 individuals and alleges irregularities in the original $209.6 million procurement.
The procurement questions have extended into airline management. Captain Subash Rijal, director of the Operations Department, was reappointed despite previous associations with procurement scandals, prompting concerns about “institutional collapse.”
Calls for structural change are growing as capacity tightens
Captain Rameshwar Thapa has called on the government to convert Nepal Airlines into a public limited company. He linked the proposal to what he described as “years of mismanagement.”
The airline must now manage scheduled heavy checks, approaching cycle limits and a network that depends on two widebodies. It also faces pressure to add destinations if it wants to raise aircraft utilization.
A further maintenance slip could reduce service to Dubai, Dammam and Narita, or force travelers onto connecting airlines. The carrier’s spokesperson has said it will try to avoid cancellations, but delays remain possible whenever an aircraft cannot operate.
The immediate question is no longer whether maintenance affects the long-haul fleet. It is which A330 is available, which one has been cleared, and whether the next maintenance slot will hold. Nepal Airlines’ latest operational position must be measured against the August 6 return to Kathmandu, while the remaining aircraft undergoes the work needed for continued service.
