Twin-engine aircraft V-22

piston engine

Overview The Nacelle Improvement (NI) Program is a targeted upgrade designed to modernize the V-22's most maintenance-intensive system: its nacelles. By simplifying wiring, enhancing structural components, and integrating maintainer-informed feedback, NI improves reliability, sustainment and mission readiness for the V-22 fleet over the next 30 years.

Program Summary The NI effort simplifies wiring, strengthens structures, reduces maintenance complexity, and incorporates feedback from maintainers to deliver longer part life, reduced downtime, and improved fleet sustainability.

Key benefits

• 24,000 hrs recovered: NI has recovered over 24,000 maintenance man-hours for AFSOC, equating to more than 1,000 days of maintainer time redirected to mission-critical tasks.
• +10% Readiness: A 10% readiness increase validated by 10,000+ flight hours on modified CV-22 aircraft.
• -75% Maintenance Time: NI delivers four times longer flight hours between critical part changes and reduces maintenance time by 75%.
• Modernized design: Simplified wiring and strengthened structures improve reliability, reduce downtime, and extend service life.

Strategic Impact NI enables agile combat employment by significantly increasing aircraft readiness, enhancing maintainability and reducing overall lifecycle cost to the V-22 fleet.

Timeline

• 2021: NI installation begins on V-22.
• 2021: First CV-22 NI modification completed at Amarillo.
• 2022: Fleet rollout begins.

Performance Validation Benefits have been validated through more than 10,000 flight hours on modified CV-22 aircraft and measured maintenance-hour recoveries for operational units.

Quote "Nearly 60% of all maintenance actions occur within the V-22’s nacelle area, so the NI effort is designed to attack the highest reliability and readiness degraders while maximizing return on investment for the taxpayer." — Kurt Fuller, SVP, Military Fielded Programs, Bell

Sustaining Superiority With NI, the V-22 remains a cornerstone of vertical lift, offering unmatched range and flexibility with improved readiness and maintainability projected into 2055 and beyond.
