General requirements to be met by a CAMO are facilities (offices and documentation storage), a Continuing Airworthiness Management Exposition (CAME) which must be approved by the competent authority of the country or EASA and company procedures (to comply with Part M requirements). A CAMO can also be the operator of the aircraft.
In 1965 CAR 1.55 became Federal Aviation Regulation section 21.303. [12] The 1965 regulatory change also imposed specific obligations on the PMA holder related to the Fabrication Inspection System. [13] Amendment 21-38 of Part 21 was published May 26, 1972. [14] This was the next rule change to affect PMAs.
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.

The PHAC is submitted as part of the authorities 1st stage of involvement (SOI#1). It is important to note that: EASA wrote a certification memoranda to require the use of DO-254 for all complex electronics within a system, stating that all equipment and CBA with a Design assurance classification of A, B, C or D should meet level D objectives ...
One airworthiness regulation is found in ICAO international standard of Annex 8 to Chicago Convention on International Civil Aviation which defines "airworthy" - in respect of an aircraft, engine, propeller or part there of - as "The status of an aircraft, engine, propeller or part when it conforms to its approved design and is in a condition for safe operation".
Certification Review Item (CRI) is a document describing an item that requires disposition prior to the issuance of Type Certificate (TC), change to TC approval or Supplemental Type Certificate (STC) by European Aviation Safety Agency (EASA).
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.
A 1976 study included an evaluation of the armor required to contain the energy from 1 blade, 2 blade, and 4 blade fragments of the compressor and turbine stages of General Electric CF6 and Pratt & Whitney JT9D engines; although the 4 blade fragment was unlikely to occur, containing it would have required a steel plate 1.212 inches (30.8 mm ...
