Many older aircraft systems that are still in use worldwide are required to remain in service for many more years to come, either due to fleet replacement cost limitations or due to issues related to integration into existing fleet management systems. A good example of a "legacy" aircraft is the Hercules C130 which had its maiden flight in August 1954 and is still in active service, albeit through many improved variants.

Philip HAUPT has a network of specialists with over 30 years experience that work in the following areas related to re-engineering of  such systems:

• Failure investigations
• Structural and duty cycle analysis
• Re-engineering of old systems
• New materials selection
• Component redesign
