The team of qualified design engineers performs all of the expected engineering design functions, including Finite Element Analysis, stress and fatigue analysis as well as design certification and qualification using drop testing, static strength testing and performance analysis.

Qualification Testing Capabilities:
• Drop test
• Landing gear reliability demo test
• Fatigue test
• Static strength test
• Performance analysis

Service and support
APPH offers a full range of support services to it's customers to ensure that aircraft are kept in operation. Personnel are available to travel worldwide at short notice to help customers should they require it.

From initial spares provisioning, through normal spares supply to a 24 AOG service, APPH will ensure that parts are available when required. APPH either supplies direct from it's facilities or through distributors, whichever is more appropriate.

Design and development
In many ways the APPH Runcorn Engineering Division forms the heart of our organisation. It is here that ideas originate, innovative solutions are explored and systems are tested and certified. Working in close partnership with clients, APPH offers a fully comprehensive service that covers initial concept through final design to lifetime engineering support. Solutions include landing gear systems, flight controls and hydraulic system assemblies for both civil and military aircraft.

Whatever the project, the aim of APPH is to evolve answers to the challenges facing the aerospace industry over issues such as performance, weight, reliability, maintainability and cost of ownership. To ensure the customer's design targets are met, APPH design and stress engineers work as an integrated team for each project.

A good example of this is the program for the SAAB JAS39 Gripen Advanced Combat Aircraft, where APPH designed, certified and manufactured the entire landing gear system including struts, stays, retract actuators, the electro-hydraulic selector and the steering control valve.
