ABSTRACT
The aircraft maintenance, engineering and continuing airworthiness keep the aircraft serviceable and may be divided into separate departments for each type of maintenance activity. Often, particularly in smaller airlines and some low-cost carriers (LCCs), maintenance is contracted out to an approved third-party engineering company, or Maintenance and Repair Organization (MRO). This chapter discusses the major airworthiness codes, making a brief examination of two systems, the USA Federal Aviation Regulations (FARs) and the European Aviation Safety Agency (EASA) Regulations. The decision to enter the aviation industry at the operational level means that the operator and manufacturer will be bound by the obligations and duties prescribed in the safety regulation system. The US system of law and administration has forced the Federal Aviation Administration (FAA) to be meticulous in its presentation of regulations and supporting documentation; as such, the FARs is relatively easy to access and interprets.
