• Identified by the airframe manufacturer and
  approved by the FAA
• Identify the equipment which may be degraded or
  inoperative at dispatch of the aircraft.
• Airline's responsibility to develop their own
  manual tailored to their specific equipment. (MEL)

24

• DDG Dispatch deviation guide

Involves configuration of the aircraft
Information on panels, fairings, and similar
variations in configuration that can be
nonstandard at dispatch as long as it does not
affect the safety of flight.
To secure the aircraft and the system against
inadvertent operation when some of the MMEL items
are inoperative or degraded at dispatch require
actions
25
Manufacturers Documentation Maintenance/Engineer
ing/Planning

• Whenever the airframe manufacturer or the engine
  manufacturer have modifications or suggestions
  for improving maintenance and/or servicing, they
  will issue appropriate paperwork to the affected
  airlines.
• SB Service Bulletins
• SL Service Letter
• MT Maintenance Tip

A service bulletin (SB) is usually a modification
of a system that will provide improved safety or
operation of a system and includes a detailed
description of the work and parts required.
A service letter (SL) usually provides
information to improve maintenance actions
without equipment modification.
The maintenance tip is a suggestion for
maintenance personnel to assist in their work or
improve conditions.

• Advisory circulars (ACs)
• An advisory circular is a document issued by the
  FAA to provide assistance to operators on meeting
  the requirements of various FARs.

30
FAAs Documentations

• Airworthiness Directives (ADs)
• Issued by the FAA (Design Authority) to correct
  an unsafe condition that exists in a product
  (aircraft, aircraft engine, propeller, or
  appliance) and a condition that is likely to
  exist or develop in other, similar products.
• An AD, whose incorporation is mandatory, may be
  issued initially by the FAA or may be an action
  after the airframe manufacturer has issued a
  service bulletin (SB)
• AD will include
• (a) a description of the unsafe condition
• (b) the product to which the AD applies
• (c) the corrective action required
• (d) date of compliance
• (e) where to get additional information
• (f) information on alternative methods of
  compliance if applicable.

33
FAAAir Operators Documentation

• Operations specifications
• Written by the airline in accordance with strict
  FAA requirements and usually with the help of an
  FAA representative.
• Refers to numerous other documents to avoid
  duplication and details the airline's
  maintenance, inspection, and operations programs.
• Technical policies and procedures manual
• Primary document for the airline's ME operation
  and, with other documents supplied by the
  airframe manufacturer, serves as the FAA
  requirement for a maintenance manual per AC
  120-16D.
• Usually written by engineering, to ensure
  technical accuracy, from inputs supplied by
  management of the various ME organizations.
• Define exactly how all ME functions and
  activities will be carried out.

The TPPM is sometimes called the policies and
procedures manual (PPM), general maintenance
manual (GMM), or the maintenance organization
exposition (MOE)
34
Air Operators Documentation

• IM Inspection manual
• May be a separate document distributed primarily
  to QC personnel, or it can be a chapter in the
  TPPM (usual approach).
• Relate to all inspection activities within ME
• (a) mechanic inspection tasks from the MPD or the
  MRB report
• (b) QC inspector's tasks
• (c) special inspections (hard landings, bird
  strikes, etc.)
• (d) the airline's Required Inspection Item (RII)
  program
• (e) the paperwork, forms, and reports required to
  carry out these functions.

35
FAAAir Operators Documentation

• RPM Reliability program manual
• Airline's reliability program must be approved by
  the regulatory authority
• Minimum equipment list (MEL)
• Customize the MMEL for the operator particular
  airframe/engine configuration.
• The operator must carry copies of this MEL in
  each aircraft for flight crew reference.
• The applicable items in the DDG and the CDL
  should also be included with the MEL.
• Task cards
• To avoid unnecessary duplication of certain
  actions, and the unnecessary opening and closing
  of the same panels, then the operator write their
  own task cards to spell out exactly what to do
• Engineering orders (EO)
• Official paper work, issued by engineering and
  approved by QA
• Some airlines called simply a "Work Order."

36
What are some examples of RIIs?

• RII examples
• a. Installation, rigging, and adjustments of
  flight controls and surfaces.
• b. Installation and repair of major airframe or
  engine structural components.
• c. Installation of an aircraft engine,
  propeller, propeller blade, or rotor.
• d . Installation, repair, and calibration of
  certain avionics and navigational equipment.

37
Air Operators Documentation

• - What is an Air Operator ?
• Air operator or Aircraft operator means any
  person which provides the service of transport of
  goods or passengers by aircraft
• - What is an Air Operator Certificate?
• A Certificate authorizing as operator to carry
  out specified air transport operation.

AIR OPERATOR CERTIFICATION
39
Air Operators Documentation

• THE AIR OPERATOR CERTIFICATE - ICAO ANNEX 6,
• 4.2.1.1 An operator shall not engage in
  commercial air transport operations unless in
  possession of a valid air operator certificate or
  equivalent document issued by the State of the
  Operator.
• 4.2.1.2 The air operator certificate. shall
  authorize the operator to conduct commercial air
  transport operations in accordance with such
  conditions and limitations as may be specified.

40
FAAAir Operators Documentation

• 4.2.1.3 The issue of an AOC .by the State of
  the Operator shall be dependent upon the operator
  demonstrating an adequate organization, method of
  control and supervision of flight operations,
  training programme and maintenance arrangements
  consistent with the nature and extent of the
  operations specified

  AOC is best organized in phases and will normally
  take following sequence
• 1. Pre-application phase
• 2. Formal application phase
• 3. Document evaluation phase
• 4. Demonstration and inspection phase
• 5. Certification phase
