A vital element in the development process at APPH UK is the testing of the equipment to verify functional and environmental performance.

To this end, we offer in-house testing facilities with tailored capabilities housed across two laboratories. Allowing us to accommodate the development and qualification testing typically associated with landing gear systems, these include, for example:

  • Drop Testing
  • Static Strength Testing
  • Fatigue Testing
  • Environmental Testing
  • Performance & Endurance Testing

Over the years our engineering teams we have successfully developed landing gear systems that are recognized for their excellence, which in conjunction with the comprehensive through life support we offer for our equipment, has allowed us to develop long term, multi-platform, relationships with many of our customers.
