EASA is responsible for new type certificates and other design-related airworthiness approvals for aircraft, engines, propellers and parts. EASA works with the EU member states' civil aviation authorities (CAAs) but has taken over many of their functions in the interest of aviation standardisation across the EU and in the non-EU member Turkey.

ATA 100 contains the reference to the ATA numbering system which is a common referencing standard for commercial aircraft documentation. This commonality permits greater ease of learning and understanding for pilots, aircraft maintenance technicians, and engineers alike.
Similar standards are maintained by other aviation authorities. For example European Technical Standard Orders (ETSO) by EASA for the European Union, [3] with limited reciprocal equivalence on a per-country basis. [4] These often have the same numbers as FAA TSOs. For example, the FAA TSO for aviation headsets is C139.
ATA Spec 100 [1] ' and iSpec 2200 [2] are information standards for aviation maintenance and flight operations [3] published by Airlines for America (formerly Air Transport Association). [ 4 ] These standards provide recommended specifications for the content, structure and deliverables to meet communication requirements [physical, electronic ...
Aerospace bearings are the bearings installed in aircraft and aerospace systems including commercial, private, military, or space applications. Materials include M50 tool steel (AMS6491), carbon chrome steel (AMS6444), the corrosion resistant AMS5930, 440C stainless steel, silicon nitride (ceramic) and titanium carbide-coated 440C.
Aerodynamic bearings: The gas is pressurized by the relative velocity between the static and moving surfaces in the bearing. Such bearings are self-acting and do not require an external input of compressed gas. However, mechanical contact occurs at zero speed, requiring a particular tribological consideration to avoid premature wear.
The European Aviation Safety Agency (EASA) was created in 2003 and reached full functionality in 2008, and has since taken over most of the JAA functions. JAA Certification Specifications, formerly known as JARs, are recognised by EASA as an acceptable basis for showing compliance with their national airworthiness codes.
JAR-OPS 1 is the Joint Aviation Requirement for the operation of commercial air transport (aeroplanes). Any commercial airline within the European Union flying jet or propeller aircraft has to comply with this standard.
