The successful Return to Service (RTS) of the A321neo highlights the strong, enduring partnership between SIAEP and Hawaiian Airlines, demonstrating a shared commitment to the highest standards of safety, quality, and operational efficiency. The HMV encompassed a comprehensive range of maintenance, repair, and overhaul tasks critical to ensuring the aircraft’s long-term airworthiness and reliability.

We are proud to support Hawaiian Airlines as they uphold their commitment to safety and the famed Aloha Spirit for their passengers.”
The A321neo is a critical component of Hawaiian Airlines’ long-haul narrow-body fleet, serving key routes across the carrier’s network. Minimizing aircraft downtime is essential for maintaining flight schedules and passenger trust.
“The prompt and flawless return of N228HA is vital for our operations, and we deeply value the expertise SIAEP brings to the table,” commented a Hawaiian Airlines official. “Our partnership extends across the globe, from our home in North America to SIAEP’s facility in Asia, creating a synergy that directly translates into the consistent, reliable service our guests expect. This successful HMV completion ensures this modern aircraft continues to deliver a safe and comfortable travel experience.”
