The formal document which details the way in which all maintenance tasks carried out on an aircraft shall be accomplished. This includes items such as lubrication system functional checks and servicing of the airplane but usually excludes structural repairs and modifications.
The information in this manual is designed to help aircraft owners and maintenance personnel obtain optimum service from their bias and radial aircraft tires. The discussions contained in this part are designed not only to teach how to properly operate and maintain aircraft tires, but also to demonstrate why these techniques and procedures are necessary.
DALLAS - To maintain structural and operational integrity, systems reliability, simplify, modify, and enhance operations, customer satisfaction, and at a more significant level to ensure its airworthiness for the safety of passengers and crew, an aircraft must undergo various scheduled and unscheduled checks, maintenance, repair, and occasionally overall replacement of some systems or components during its operational life.
Maintenance and repair staff use different documents/manuals to make their work easier and successful when performing their duties in the hangar or at the ramp. The manufacturer, component suppliers, various aviation authorities, or aircraft operators may be responsible for creating these documents. These are a few of them:
Servicing, installation and removal, deactivation and reactivation, test and adjustment, operational test, functional test, system test, BITE test, inspection/check, detailed inspection, general visual inspection (GVI), special thorough inspection (SDI), painting, repairs and cleaning are among the tasks covered by AMM.
The IPC supplements the Aircraft Maintenance Manual (AMM). Still, since it lacks the same level of approval, it should only be used as a supplementary source, with the AMM serving as the final authority in case of any discrepancies.
Manufacturers frequently provide IPC data digitally in electronic parts catalogs (EPC), which can be either locally installed software or web applications hosted centrally. Typically, an EPC allows virtually disassembling the product into its component parts to locate the necessary part(s).
The aircraft system manual, or ASM, illustrates the principle of operation of the aircraft's systems and subsystems. The ASM does not show parts as they appear or function but indicate the location of components concerning each other.
A standardized typical diagrammatic representation of the actual connections and physical structure of an electrical system or circuit is referred to as a wiring diagram, and details like these can be found in Aircraft Wiring Manual.
Wiring diagrams demonstrate the physical connections and location of electrical components, how the aircraft's wires are connected and organized, and their part number and serial number. An electrical system or circuit can be manufactured or malfunctions troubleshot using a wiring diagram for various aircraft.
When airplane maintenance engineers are troubleshooting, maintaining, or making improvements to the loads linked to the electrical network, AWL, which consists of wire terminations, connectors, terminals, stripes, wire routing, and clamps, may assist.
The Electrical Standard Practices Manual (ESPM) is contained in the Instructions for Continued Airworthiness (ICA) which provides procedures and descriptive data for the electrical installations aboard airplanes.
The standard practices material in this manual instructs maintenance professionals on how to do maintenance for the ongoing airworthiness of the aircraft. When installing or repairing the electrical and avionics systems in the plane, the ESPM always recommends the best practices.
Information on specific tools and test equipment recommended by the aircraft manufacturer and vendors is provided to aircraft maintenance personnel in the tool and equipment manual (TEM) so they can perform the maintenance, servicing, repair, and troubleshooting tasks outlined in the aircraft maintenance manuals (AMM) and required to maintain the aircraft's airworthiness.
The standard tools and equipment used in airports, such as the escalators for passengers, baggage-loading mechanisms, and tow trucks, are not included in this manual. Additionally, it excludes data pertaining to the specific tool's operation, maintenance, and overhaul.
MMEL is a document that lists the systems, instruments, and equipment aboard a specific type of aircraft established by the manufacturer (for example, Boeing or Airbus) and approved by the State of Design (for example, FAA or EASA). It identifies components that may be temporarily inoperable at departure while maintaining an acceptable level of safety. The MMEL might come with unique operational instructions, restrictions, or procedures.
The MMEL is not to include any equipment that, if inoperative, is likely to significantly impair the performance of the aircraft, conflicts with the restrictions or invalidates the emergency procedures of the AFM (Aircraft Flight Manual) or an airworthiness directive, or that is covered by the Configuration Deviation List (CDL) unless expressly stated in the MEL or AFM.
A particular type of aircraft's minimum equipment list (MEL) is a document that lists the instruments, equipment, and systems that can be inoperative at departure while still maintaining a reasonable level of safety.
The MEL is created by an operator that complies with or exceeds the MMEL established for the aircraft type and is approved by the operator's state. If any instruments, equipment, or systems fail, it helps the pilot in command (PIC), flight dispatchers, and maintenance engineers evaluate if a flight can be dispatched or continued from any intermediate stop.
When the State of the Operator is not the State of Registry, the State of the Operator must ensure that the MEL does not interfere with the airplane's ability to meet the State of Registry's airworthiness criteria during the approval process. Section 6.1.1 of ICAO Annex 6 Part I Chapter 6.
A configuration deviation list (CDL) is a section of the aircraft flight manual (AFM) created by the manufacturer of an aircraft type with the State of Design's (manufacturer's) approval. It identifies any external parts of an aircraft type that may be missing at the commencement of the flight. However, the aircraft is still airworthy and, where necessary, contains any information on associated operating restrictions and performance correction.
It is essential to distinguish the CDL from the MEL. The CDL deals with situations where external aircraft parts, such as fairings, flaps, slats, winglets, aerodynamic seals or panels, and other lift augmentation devices, are missing or have fallen off. The MEL discusses the limitations of aircraft operation if a system is not operational or has malfunctioned, for example, transponder failure.
If there isn't a CDL for a particular type of aircraft, then flying with missing external parts indicates that the aircraft isn't in its original certified configuration and isn't airworthy. The operator should have a procedure in place to ensure that all flaws compromising the aircraft's safe operation are fixed within the parameters outlined by the approved minimum equipment list (MEL), configuration deviation list (CDL), or maintenance data, as applicable.
The Structural Repair Manual (SRM) is a publication that provides in-depth descriptions of the identification, acceptable damage limitations, and repairs for the primary and secondary structures of aircraft. The manufacturer provides this guide and has received state-of-design approval.
Additionally, SRM provides information on substitute materials and fasteners and a brief description of specific procedures combined with structural repairs, like protecting repair parts and sealing integral fuel tanks. A special repair scheme must be requested from the aircraft manufacturer if acceptable methods to repair the discovered structural damage to the aircraft are not included in the SRM.
The Trouble Shooting Manual (TSM) is a manual containing thorough and systematic procedural coverage of aircraft warnings (like ECAM, EFIS, LOCAL, and OBSV), malfunction reports (for crew, maintenance), and CFDS (Centralized Fault Display System) messages to identify, confirm, isolate, and rectify aircraft malfunctions.
It also addresses defects not tracked by the aircraft system and is intended to offer a quick and accurate method of isolating faults and provides suggestions for measures to be performed to minimize aircraft downtime.
The CMM's maintenance tasks provide sufficient information to restore the component or a unit to a serviceable state and include the data necessary for inspecting, repairing, adjusting, testing, and other maintenance operations. The Illustrated Parts List (IPL), which lists each piece of a component that needs to be disassembled for shop maintenance, contains a list of the parts that are subject to CMM.
The manufacturer publishes the Aircraft Recovery Manual (ARM), which contains comprehensive technical and procedural information required to recover a particular type of disabled aircraft concerning service return.
A Service Bulletin (SB) is a document used by manufacturers of aircraft types, engines, or component parts to provide essential and practical information about aircraft safety, enhancing maintenance and product life, or design modification to boost performance which can be included in aircraft.
Service Bulletin compliance may or may not be mandatory, but when it comes to safety, it is always considered. When an SB addresses a safety risk rather than a product improvement, it is published as an Alert Service Bulletin (ASB), in which case the state where the aircraft is registered adopts it and publishes an associated Airworthiness Directive (AD). Because it covers significant conditions that may occur in a product (such as an aircraft engine, airframe, system, or propeller), the AD is a requirement that must be followed.
