Description

Garuda Indonesia Boeing 737-300, 737-400, 737-500 Continuous Airworthiness Maintenance Program (CAMP Rev 40)

The Boeing 737-300, 737-400, 737-500 Continuous Airworthiness Maintenance Program (CAMP Rev 40) is an exhaustive, engineering-approved technical document (Doc No. MZ-TD-04-737) establishing mandatory scheduled maintenance intervals, routine checks, and detailed task breakdowns for commercial Boeing 737 Classic fleets. Formulated in compliance with DGCA requirements, Boeing Maintenance Planning Data (MPD D6-38278), MRBR recommendations, Certification Maintenance Requirements (CMRs), and Airworthiness Limitations (AWLs/CDCCLs), this document serves as the regulatory operational baseline for heavy maintenance planning, line transit handling, and structural integrity oversight.
