Aerospace group

Parker Aerospace is a global leader in hydraulic, fuel, flight control, pneumatic, electronics cooling, and fluid conveyance components and systems and related electronic controls for aerospace and other high-technology markets. Its products are used on aircraft manufactured throughout the world today, including commercial transports, military fixed-wing planes, regional and business aircraft, helicopters, missiles, and unmanned aerial vehicles. Based in Irvine, California, Parker Aerospace operates 39 facilities in the Americas, Europe, and Asia. The latest programs include the COMAC C919, Rolls-Royce Trent XWB engine, Bombardier CSeries and Global 7000/8000, Embraer Legacy 500/450, Mitsubishi Regional Jet, Gulfstream G650, Model 850 Citation Columbus, and Airbus A350 XWB.

Greener aircraft and reduced emissions

Parker Aerospace is a longtime Airbus supplier, with special competencies in multifunctional system integration. Parker is partnering with Airbus to develop fuel cell technology as an alternative energy source for on-ground and in-flight electrical power supply. Within this partnership, Airbus will be responsible for the overall aircraft system architecture and technology integration into the aircraft, and Parker will supply the multifunctional fuel cell system and manage different subsystem suppliers. A fuel cell is a device which transforms the energy contained in hydrogen and oxygen into electricity through a direct chemical conversion at a low temperature without moving parts. The exhaust product is water, and in the case of an air-breathing system, oxygen-depleted air. The electricity produced by fuel cells can be cleaner and more efficient than combustion engines, depending on the hydrogen source. In addition, the water and the oxygen-depleted air (inert gas) can be used on the airplane to substitute the water and inerting systems.

The objective of the cooperation is the development of a technology demonstrator followed by a joint flight test campaign for the middle of the decade, including operational and infrastructural tests. With Parker Aerospace involved in the project from this earliest phase, industrialization can be considered throughout the development of the process, rather than at the end. Airbus considers fuel cell technology as a key contributor to meeting the ACARE 2020 goals, which foresee the reduction of CO2 emissions by 50%, NOX emissions by 80%, and noise by 50%.

Boeing 737 incidents

In 1995, it was discovered that failures in a servo unit supplied by Parker Hannifin to Boeing for use in their 737 aircraft may have contributed to several incidents, including that of United Airlines Flight 585 and USAir Flight 427.[5][6]

In 2004, a Los Angeles jury ordered Parker Hannifin to pay US$43 million to the plaintiff families of the 1997 SilkAir Flight 185 crash in Indonesia. Parker Hannifin subsequently appealed the verdict, which resulted in an out-of-court settlement for an undisclosed amount. The National Transportation Safety Committee could not determine the cause of the crash due to the near total lack of physical evidence and complete destruction,[7] this in contrast to the US National Transportation Safety Board, however, which disagreed and determined that the crash was caused, possibly intentionally, by the pilot.[8][9]

The FAA ordered an upgrade of all Boeing 737 rudder control systems by November 12, 2002. Parker argued that the components they supplied were not at fault, citing that the product has one of the safest records in its class, but the FAA directive went through regardless.[10]


On 18 January 2013, the F-35B variant of the Lockheed Martin F-35 Lightning II was grounded after the failure of a fueldraulic line in the aircraft's propulsion system that controls the exhaust vectoring system. This was in response to an incident on 16 January where the propulsion system experienced a fueldraulic failure prior to a conventional takeoff. The precautionary flight suspension is to preserve safety while providing time to understand the origin of the failure of the propulsion fueldraulic line.[11] The failure was found to be a manufacturing defect by Parker Hannifin's Stratoflex division.[12][13]
