B737 CDL Limitations

  • The Configuration Deviation List (CDL) limitations must be listed on a placard affixed in the cockpit in clear view of the pilot-in-command and other appropriate crew members.
  • Operation with those missing parts requiring a reduction of VMO/MMO is permitted only when the airplane has the appropriate alternate VMO set prior to flight.
  • The pilot-in-command will be notified of each operation with a missing part(s) by listing the missing part(s) in the flight or dispatch release.
  • The operator will list in the aircraft logbook an appropriate notation covering the missing part(s) on each flight.
  • If an additional part is lost in flight, the airplane may not depart the airport at which it landed following this event until it again complies with CDL limitations. This does not preclude the issuance of a ferry permit to allow the airplane to be flown to a point where the necessary repairs or replacements can be made.
  • Unless otherwise specified herein, parts from different sub-systems may be missing. In addition, any combination of the authorized number of parts from a single sub-system may be missing unless otherwise specified.
  • The takeoff performance decrements in the CDL are to be applied to the performance limited takeoff weights determined from field length, first segment climb, second segment climb, final segment climb, or obstacles in the takeoff flight path.
  • The enroute performance decrements in the CDL are to be applied to the weight limit determined from enroute, one-engine-inoperative climb performance.
  • The landing performance decrements in the CDL are to be applied to the performance limited landing weights determined from landing field length, landing climb, or approach climb.
  • The numbering and designation of sub-systems in the CDL are based on ATA Specification 100. The parts within each sub-system are identified by functional description and, when necessary, by part numbers.
  • Items are applicable to all 737 MAX engine/airframe combinations unless otherwise designated.
  • The CDL does not provide information regarding dispatch with missing fasteners. Refer to Structural Repair Manual (SRM) Section 51-10-05 for conditions and limitations which permit operations with missing fasteners.
