Spirit Airlines says its exposure to the latest Pratt & Whitney Geared Turbofan (GTF) engine issue is unique and material, and it's having an impact on margins. 

While the issue disrupted deliveries to Boeing and impacted revenues, negative impacts will be partially offset by Spirit’s accelerating 737 production line.

The cargo carrier is investing nearly $200 million to grow maintenance capacity at its Americas hub.

Among Triumph’s business lines, commercial aftermarket performed the best, on the back of continued improvement in overall air travel metrics.

The aircraft-maker has finished its proposed redesign of older 737 nacelles, but it must analyze maintenance-related errors to help mitigate their risk.

The commercial aftermarket outlook remains highly favorable as total sales rose 23% year-on-year in the 2023 second quarter (Q2).

Aviation Week's Lee Ann Shay, James Pozzi and Dan Williams discuss the present and future of the A380 and its aftermarket.

MRO revenue drivers included the PW1100G-JM and the V2500 engine programs.
