On a normal aircraft redelivery or at an early lease termination the importance of receiving a certified status list from the airline CAMO or Quality Assurance department ( for non EASA) is critically important when performing the technical records review. The certified and dated list is the benchmark or “hard point” DATE that allows the reviewer record the Open Item List (OIL) findings and build the records folders with the compliant documents.
Current Time in Service: Report showing the TSN (Time Since New – i.e. total Flight Hours since new manufacture) and CSN (Cycles Since New – i.e. total Cycles since new manufacture) for Airframe, Engines, APU and Landing Gear.
Airworthiness Directive Status: List of all the ADs generally applicable to the Aircraft/Engine type showing for each AD, method of compliance, interval, last done, next due (TSN,CSN, Date). The status should be broken down by individual task of the AD. If not applicable, then must show reason why. A separate status is preferable for each of the Airframe, Engines, and Appliances.
Service Bulletin Status: A certified list of all Manufacturer’s Service Bulletins issued for the Aircraft/Engine type showing for each Service Bulletin, whether or not incorporated, intervals, last accomplished, next due (TSN, CSN, Date), as applicable to the Service Bulletin type. A separate status is preferable for each of the Airframe, Engines, and APU.
Modification Status : A certified summary of all modifications accomplished on the Aircraft/Engine which are not accomplished in accordance with a service bulletin issued by the Manufacturer. A separate status is preferable for each of the Airframe, Engines, and APU.
Engine & APU LLP Status : A certified list for each engine and APU showing all the LLPs incorporated in the engine by P/N (Part Number) and S/N (Serial Number), showing the Life Limit of the part, the Hours and Cycles accumulated and the Hours and Cycles remaining at each Thrust Setting (Engines).
Landing Gear LLP Status: A certified list for each Landing Gear assembly showing all the LLPs incorporated in the assembly by P/N and S/N, showing the Life Limit for the part to which it can be fitted, the Flight Hours and Cycles accumulated on each part, and the Flight Hours and Cycles remaining for each part.
Hard Time Parts Status: A certified list of the Hard Time Parts which require replacement or off aircraft maintenance at time intervals specified in the MPD (at the end of the lease) or Maintenance Program (during the lease). The list should show by P/N and S/N the Hard Time Event maintenance required, the hard time limit (Flight Hours, Cycles or Calendar Time, as appropriate), last done, next due (TSN, CSN, Date).
Other Status lists would include STC, Repair File, Loose Equipment, Fitted Listing, ALI and CMR List.
