Continuous airworthiness maintenance program (CAMP) for two-engine ETOPS

Airlines operating two-engine aircraft on ETOPS (Extended Operations) flights must develop and follow a specialized continuous airworthiness maintenance program that supplements their standard maintenance procedures. This program requires maintaining an ETOPS maintenance document that lists all critical systems and procedures.

Before each ETOPS flight, maintenance personnel must complete a pre-departure service check verifying all ETOPS-significant systems, reviewing maintenance records, and inspecting the aircraft inside and out, including engine and APU oil levels. An ETOPS-qualified mechanic must perform and sign off on ETOPS-specific tasks, and an authorized signatory person must certify the check is complete.

The regulation restricts "dual maintenance"—working on the same or similar critical systems during one maintenance visit—unless different technicians perform the work or proper supervision and verification testing occurs. Airlines must also establish verification programs, parts control procedures, centralized maintenance control, and reliability programs specifically for ETOPS operations.
