Viva Grounds Average of 21 Jets Monthly Amid Pratt Engine Recalls Between September 2023 and October 2025, Viva Airlines has experienced significant operational disruptions, averaging 21.3 grounded aircraft per month due to widespread recalls of Pratt & Whitney PW1100G and PW1400G engines. This analysis, conducted by aviation consultant Armando Sánchez Mata, reveals that the low-cost carrier faced monthly grounding figures ranging from three to 26 jets as its fleet expanded from 78 to 119 aircraft over the 26-month period. Impact on Fleet Availability and Operational Response The most severe disruption occurred in August 2024, when 26 aircraft—equivalent to 24.5% of Viva’s fleet—were out of service. By May 2025, the grounding peaked within the A320neo subfleet, with 17 jets inactive, representing 68% of that group. Sánchez Mata highlighted a direct correlation between the decline in flight hours throughout 2024 and the reduced availability of aircraft caused by these engine issues. In response to the shortage, Viva entered into wet-lease agreements with Avion Express and SKY Airline from late 2023, supplementing its capacity with A320ceo and A320neo aircraft. However, this strategy attracted criticism from the Colegio de Pilotos Aviadores (CPAM) and the Asociación Sindical de Pilotos Aviadores (ASPA), who raised concerns about the employment of foreign pilots and the constitutional mandate requiring Mexican-born flight crews for operations within Mexico. Root Causes and Industry-Wide Effects The engine recalls originate from defects in critical Life Limited Parts (LLP), including discs, hubs, and seals within compressors and high-pressure turbines. Since 2023, the US Federal Aviation Administration (FAA) has issued multiple airworthiness directives mandating rigorous inspections and component replacements. These measures have affected not only Viva but also other carriers such as Volaris, Spirit Airlines in the United States, ITA Airways in Italy, and numerous airlines worldwide. Volaris has similarly faced substantial operational challenges due to the Pratt & Whitney engine inspections, extending its review program through 2028. Despite grounding a portion of its fleet, Volaris anticipates a capacity growth of 6% to 8% in the coming year. CEO Enrique Beltranena projects that the primary impact of these disruptions will subside by 2027, with only limited delays expected into 2028. Volaris, one of over 40 airlines affected by the accelerated inspections announced in 2023, has secured a multi-year compensation agreement with Pratt & Whitney. In the third quarter of 2025, an average of 36 Volaris aircraft were grounded, a figure expected to decrease to 32–33 in 2026. Aircraft Storage and Broader Market Implications Viva has primarily stored its grounded jets at the Roswell International Air Center in New Mexico, with additional aircraft parked in Monterrey, Mexico City, and Aguadilla, Puerto Rico. As of late October 2025, 26 aircraft—comprising 17 A320neo and nine A321neo models—were distributed across these facilities. The ongoing engine issues have intensified scrutiny from both airlines and regulators, prompting some carriers to explore alternative engine suppliers. Competitors such as GE Aerospace-Safran and Embraer are actively enhancing their engine offerings to attract customers seeking to avoid Pratt & Whitney’s current challenges. Recent industry developments include Pratt & Whitney’s negotiations with Airbus to secure engine supplies, while Swiss International Air Lines has resorted to cannibalizing its A220-100 fleet to maintain the operability of its A220-300 aircraft. Meanwhile, Embraer reports significant improvements in the PW1900G engine’s performance and anticipates no grounded aircraft by the end of next year. Globally, the aircraft supply chain remains under considerable strain. According to the International Air Transport Association (IATA), the backlog of new aircraft orders has reached a record 17,000 units. Approximately 14% of the world’s fleet—around 5,000 of the 35,166 aircraft in service as of December 2024—remains parked for various reasons. Sánchez Mata’s analysis utilized data from Airfleets and Flightradar24, cross-referenced with official flight-hour records from Mexico’s Agencia Federal de Aviación Civil (AFAC). The study classified an aircraft as “grounded” if it had not operated a commercial flight for at least 70 days.

Airbus Calls for Urgent Modifications to Thousands of Aircraft Amid Solar Radiation Risks Airbus has issued a call for urgent modifications to approximately 6,000 aircraft worldwide, citing concerns that intense solar radiation could jeopardize critical flight control data. This development arises amid heightened awareness of the risks posed by solar activity, particularly coronal mass ejections (CMEs), which have the potential to disrupt aircraft electronics and satellite systems essential for safe flight operations. The Impact of Solar Activity on Aviation Electronics Coronal mass ejections occur when the sun releases plasma into space, emitting heavily charged particles that interact with the Earth's upper atmosphere. Dr. Ian Getley, a former Qantas captain and expert in cosmic and solar radiation in aviation, explains that the severity of a CME directly correlates with the likelihood of interference affecting satellites and aircraft electronics operating above 28,000 feet (8.5 km). These charged particles can induce disruptions in onboard electronic systems, including sensitive avionics and flight control data. Dr. Getley’s interest in this phenomenon was sparked by his own experience of electronic disturbances during a 2003 flight between Los Angeles and New York. His research underscores how solar radiation can increase the density of charged particles in the atmosphere, thereby compromising the integrity of critical flight systems. Regulatory Response and Industry Implications In response to these concerns, the European Union Aviation Safety Agency (EASA) has issued an emergency directive mandating that airlines implement the necessary software and hardware updates before affected aircraft are permitted to resume service. This directive has prompted operational challenges across the aviation sector, with carriers such as Air New Zealand and Delta Airlines warning of potential delays and cancellations as they work to comply with the new safety requirements. Although some airlines expect only limited disruptions, the sheer scale of the modifications—impacting thousands of planes globally—suggests that significant operational disturbances are likely, especially during peak travel periods. Airlines are expediting the update process to mitigate passenger inconvenience while upholding stringent safety standards. This situation highlights the increasing vulnerability of modern aviation to solar activity, as the industry’s growing reliance on advanced electronic systems makes it more susceptible to space weather events. While passengers may experience temporary disruptions, industry leaders emphasize that ensuring safety remains the paramount concern.
