  3. Introduction • Quality Assurance (QA) • Airline must generate/establish maintenance and inspections programs to keep aircraft in an airworthy condition. • Referred to as the CAMP (Continuous Airworthiness Maintenance Program) • FAR 121.373 (Continuing Analysis and Surveillance) provides an additional requirement (pg 181)

  4. Introduction • Although airline must have an FAA approved maintenance and inspection program: • They must monitor these programs to determine effectiveness and implement corrective actions when not effective • The requirement is for work performed by themselves and any work performed by third-party organizations (including other airlines)

  5. Functions of Quality Assurance • Functions of QA: • Administration and Management of QA and CASS activities • Conducts QA audits of all M&E organizations • Maintenance of Technical Records • Liaison with the regulatory authority for all M&E functions

  6. Quality Audits • Audits should be detailed, fact-finding designed to look at all aspects, determine discrepancies and establish a corrective action with a finite time for correction of each discrepancy • Must review administrative and supervisory aspects of the operation as well as the performance of the work

QA Audits • Supervisor of QA responsible for auditing all outside organizations • Part suppliers, parts pools, third-party organizations and other contractors • NOTE: FAR 121.373 – “Airline responsible for monitoring all maintenance on its aircraft regardless of who performs that maintenance.”

  9. QA Audits • Certain audits may span two or more organizations or activities within M&E (pg 185-186) • Audited for their part within the larger process, procedure, or function without a full audit • Ramp Operations • Airplane Tire pressures • Shop records • Required Inspection Items (RIIs) • AD & SB compliance • Major repairs & alterations • Safety equipment • Safety training • Accident/incident reporting • Fire protection/prevention • Hazardous materials handling

  10. ISO 9000 Quality Standard • Establishes the requirement for a quality system in organizations performing design and/or manufacturing or providing technical services • ISO 9001 • For facilities that design/develop, produce, install, and service products or services to customers who specify how the product or service is to perform • ISO 9002 • For facilities that provide goods or services to the customer’s design specifications • ISO 9003 • For those doing final inspection and testing • Table 17-2 page 187

  11. Technical Records • Requirement is to ensure aircraft are maintained in airworthy condition and IAW certification req. • Records allow FAA or other regulatory authorities to validate: • Current status and that status is up-to-date • Records allow new owner/operator or lessor to validate: • Exact status w/respect to ADs, SBs, and modifications and major repairs • Know what maintenance schedule is for that aircraft • Progression of maintenance checks at time of transfer • (A, B, C, etc…)

  12. Technical Records • Classification of Records (pg 188-189) • Continuous, Routine, Repetitive and Permanent • Continuous • Continuously updated to reflect status at any point in time • Routine • Usually maintained for 15 months – may be transferred to permanent status • Repetitive • Work repeated at regular intervals (daily, transit, or letter checks) • Permanent • Permanent changes to configuration of the aircraft, engines, components, and appliances • Retained permanently
