MAINTENANCE RECORD KEEPING

• OBJECTIVE.This presentation provides guidance
  for evaluating an operator's procedures for
  utilizing, preserving, and retrieving the
  maintenance records required by the appropriate
  State Regulation.

RECORD KEEPING REQUIREMENTS
4
ICAO ANNEX 6, 8.8 Records

• The following records must be kept
• a) the TTIS (hours, calendar time and cycles, as
  appropriate) of the aeroplane and all life
  limited components
• b) the current status of compliance with all
  mandatory continuing airworthiness information
• c) appropriate details of modifications and
  repairs to the aeroplane and its major
  components..

5
ICAO ANNEX 6, 8.8 Records

• d) the time in service (hours, calendar time and
  cycles, as appropriate) since last overhaul of
  the aeroplane or its components subject to a
  mandatory overhaul life
• e) the current aeroplane inspection status such
  that compliance with the maintenance manual can
  be established and
• f) the detailed maintenance records to show that
  all requirements in the maintenance manual for
  issuance of a maintenance release have been met.

6
ICAO - Retention Periods

• The records in a) to e) shall be kept for a
  period of 90 days after the end of the operating
  life of the unit to which they refer, and the
  records in f) for a period of one year after the
  issuance of the maintenance release.
• The records shall be transferred to the new
  operator in the event of any change of operator.

7
MAINTENANCE RECORD KEEPING

• GENERAL.
• To comply with the maintenance recording
  requirements of ICAO and the States Aviation
  Regulations, the operator's maintenance manual
  must identify and contain procedures
  to complete all applicable
  documents used by the
  operator.

8
MAINTENANCE RECORD KEEPING

• CURRENT AIRWORTHINESS DIRECTIVE STATUS.
• The operator must keep records showing
• A list of ADs applicable to the aircraft
• the current status of applicable ADs,
• the method of compliance.
• the date and time in service or cycles,of
  compliance, as applicable

9
MAINTENANCE RECORD KEEPING

• TOTAL TIME IN SERVICE RECORDS
• Total time in service records may consist of
  aircraft maintenance record pages, separate
  component cards or pages, a computer list, or
  other methods as described in the operator's
  manual and approved by the NAA.

10
MAINTENANCE RECORD KEEPING

• LIFE-LIMITED PARTS STATUS RECORDS
• State Regulations should require that records be
  kept for components of the airframe, engine,
  propellers, rotors, and appliances that are
  identified to be removed from service when the
  life limit has been reached.

11
MAINTENANCE RECORD KEEPING

• AIRWORTHINESS RELEASES
• When maintenance, repair or modifications on an
  aircraft are performed, an airworthiness release
  or log entry must be completed prior to operating
  the aircraft.
• Using the procedures described in the manual, the
  operator must be able to retain all of the
  records necessary to show that all requirements
  for the issuance of an airworthiness release have
  been met.

12
MAINTENANCE RECORD KEEPING

• OVERHAUL LIST.
• The operator is required to develop procedures
  for recording the time since the last overhaul of
  all items installed on the aircraft that are
  required to be overhauled or inspected on a
  specified time basis.

13
MAINTENANCE RECORD KEEPING

• OVERHAUL/REPAIR RECORDS
• Records must be made of every component
  overhaul/repair and must include the following
• A description of the work performed or reference
  to data
• A positive identification of the person
  performing the work and the person approving the
  work

14
MAINTENANCE RECORD KEEPING

• CURRENT AIRCRAFT INSPECTION STATUS.
• A record, identifying the current inspection
  status of each aircraft must be maintained,
  detailing
• The time in service since the last inspection
• Records must be maintained for periods as listed
  in a states regulations

15
MAINTENANCE RECORD KEEPING

• MAJOR MODIFICATION AND MAJOR REPAIR.
• operators are required to retain records of major
  repairs and major modifications
• Major modifications
• record should include
• the date of modification
• a brief description of the
• work accomplished.

16
MAINTENANCE RECORD KEEPING

• MAJOR REPAIRS.
• Operators are required
• to retain records of
• major repairs

17
EVALUATION OF AN ORGANISATION
18
INSPECTION/EVALUATION OF AN ORGANISATION

• Review the operator's Maintenance Manual to check
  for procedures to ensure a suitable system for
  creating, preserving
• and retrieving required records.

19
INSPECTION/EVALUATION OF AN ORGANISATION

• REVIEW THE MANUAL PROCEDURES.
• Ensure that the State requirements are met for
  the retention of Airworthiness Release Records.
  Ensure the following
• records will be retained for (one year) after
  the work is performed or until the work is
  repeated or superseded
• The manual identifies the person(s) authorized to
  sign an airworthiness release

20
INSPECTION/EVALUATION OF AN ORGANISATION

• FLIGHT MAINTENANCE RECORDS.
• Ensure that procedures provide for the
  following entries
• Flight discrepancies to be entered
• at the end of each flight
• Corrective actions and sign-off, per manual
  procedures
• Certification of Required Inspection Items
  (RIIs), by authorized personnel
• Minimum Equipment List (MEL) deferment

21
INSPECTION/EVALUATION OF AN ORGANISATION

• TOTAL TIME IN SERVICE RECORDS
• Evaluate the method of recording total time in
  service of airframes. This record should show the
  current time in service in hours and cycles.
• Ensure that procedures are in place to retain the
  records until the aircraft is sold and that the
  records will then be transferred with the
  aircraft.

22
INSPECTION/EVALUATION OF AN ORGANISATION

• LIFE-LIMITED PARTS STATUS
• Ensure that the operator has procedures for
  tracking life-limited parts, to include the
  following informationTotal operating hours
  (including calendar time)/cycles
  accumulated Life limit (total service life)
  Remaining time/cycles Modifications

23
INSPECTION/EVALUATION OF AN ORGANISATION

• TIME SINCE LAST OVERHAUL
• RECORDS.
• Ensure that the manual includes a
  method/procedure for updating this document and
  ensuring that this document accompanies the
  aircraft upon sale

24
INSPECTION/EVALUATION OF AN ORGANISATION

• OVERHAUL RECORDS
• Ensure that the CMM describes how the last
  complete overhaul of each part is recorded. The
  record should include the following
  information Disassembly data Dimensional
  check data Replacement parts list Repair
  data/ Reassembly/test data Reference to data
  including overhaul specificationsEnsure that
  these records will be retained until the work is
  superseded by work of equivalent scope and detail.

25
INSPECTION/EVALUATION OF AN ORGANISATION

• CURRENT AIRCRAFT INSPECTION STATUS
• Evaluate the method the operator will use to
  record the time in service since the last
  inspection.
• Determine if procedures ensure that these
  records are transferred with the aircraft when
  sold.

26
INSPECTION/EVALUATION OF AN ORGANISATION

• AIRWORTHINESS DIRECTIVE (AD) COMPLIANCE.

  brief description of the modification

28
INSPECTION/EVALUATION OF AN ORGANISATION

• MAJOR REPAIR RECORDS.
• Evaluate the manual procedures to ensure that
  the operator prepares and maintains a report of
  all major repairs to each airframe, engine,
