Control of Unserviceable Components

          1. Mutilation should be accomplished in such a manner that the components become permanently unusable for their original intended use. Mutilated components should  not be able to be reworked or camouflaged to provide the appearance of being  serviceable, such as by re-plating, shortening and re-threading long bolts, welding,  straightening, machining, cleaning, polishing, or repainting.           2. Mutilation may be accomplished by one or a combination of the following procedures:                   (a) grinding,                   (b) burning,                   (c) removal of a major lug or other integral feature,                   (d) permanent distortion of parts,                   (e) cutting a hole with cutting torch or saw,                   (f) melting,                   (g) sawing into many small pieces,                   (h) any other method accepted by DGCA on a case by case basis.          3. The following procedures are examples of mutilation that are

Unsalvageable Components

       1. The following types of components should typically be classified as  unsalvageable :             a) components with non-repairable defects, whether visible or not to the naked  eye;             b) components that do not meet design specifications, and cannot be brought  into conformity with such specifications;            c) components subjected to unacceptable modification or rework that is  irreversible;            d) certified life-limited parts that have reached or exceeded their certified life  limits, or have missing or incomplete records;            e) components that cannot be returned to airworthy condition due to exposure to extreme forces, heat or adverse environment;            f) components for which conformity with an applicable airworthiness directive cannot be accomplished;            g) components for which continuing airworthiness records and/or traceability to  the manufacturer can not be retrieved.       2. It is common practice for possessors of

Unserviceable Components

             a) A component shall be considered unserviceable in any one of the following circumstances:                     1. expiry of the service life limit as defined in the maintenance program;                     2. non-compliance with the applicable airworthiness directives and other continued airworthiness requirement mandated by DGCA ;                    3. absence of the necessary information to determine the airworthiness status or  eligibility for installation;                    4. evidence of defects or malfunctions ;                    5. involvement in an incident or accident likely to affect its serviceability.             b) Unserviceable components shall be identified and stored in a secure location under the control of an approved maintenance organisation until a decision is  made on the future status of such component. Nevertheless, for aircraft not used  in commercial air transport other than large aircraft, the person or organisation  that decla

Service Life Limited Components

               M.A.503 Service Life Limited Components        (a) Installed service life limited components shall not exceed the approved service  life limit as specified in the AMP and ADs , except as provided for in point M.A.504(c).                (b) The approved service life is expressed in calendar time, flight hours, landings or  cycles, as appropriate.                ( c ) At the end the approved service life, the component must be removed from the  aircraft for maintenance, or for disposal in the case of components with a certified life limit

Component Maintenance

                                  M.A.502 Component Maintenance               (a) The maintenance of components shall be performed by maintenance organisations appropriately approved in accordance with Section A, Subpart F of  CAR M or with CAR 145.              (b) By derogation from paragraph (a), maintenance of a component in accordance with aircraft maintenance data or, if agreed by DGCA, in accordance with  component maintenance data, may be performed by an A rated organisation  approved in accordance with Section A, Subpart F of CAR-M or CAR 145 as well  as by certifying staff referred to in point M.A. 801(b)2 only whilst such components are fitted to the aircraft. Nevertheless, such organisation or certifying staff may  temporarily remove this component for maintenance, in order to improve access  to the component, except when such removal generates the need for additional  maintenance not eligible for the provisions of this paragraph. Component maintenance performed in a

Component Installation

                                          M.A.501 Installation                (a) No component may be fitted unless it is in a satisfactory condition , has been appropriately released to service on a CA Form 1 or equivalent and is marked in accordance with CAR 21 Subpart Q, unless otherwise specified in CAR 21, CAR  145 or CAR-M Section A, Subpart F.               (b) Prior to installation of a component on an aircraft the person or approved maintenance organisation shall ensure that the particular component is eligible for fitment.               (c) Standard parts shall only be fitted to an aircraft or a component when the maintenance data specifies the particular standard part. Standard parts shall only  be fitted when accompanied by evidence of conformity traceable to the  applicable standard .              (d) Material being either raw material or consumable material shall only be used on an aircraft or a component when the aircraft or component manufacturer states  s

Maintenance Data

                        A pplicable current maintenance data            1. any applicable requirement, procedure, standard or information issued by  DGCA,          2. any applicable airworthiness directive,          3. applicable instructions for continuing airworthiness, issued by type certificate   holders, supplementary type certificate holders and any other organisation  that publishes such data in accordance with CAR 21.         4. any applicable data issued in accordance with 145.A.45(d).  All applicable   maintenance data is current and readily available for use when required.  Establish a work card or worksheet system to be  used and shall either transcribe accurately the maintenance data onto such work  cards or worksheets or make precise reference to the particular maintenance  task or tasks contained in such maintenance data. Each person or organisation performing  aircraft maintenance should have access to and use: a) all maintenance related CAR’s and associated

Operator's Technical Log System

(a) In the case of commercial air transport, in addition to the requirements of M.A.305,  an          operator shall use an aircraft technical log system containing the following  information for      each aircraft:      1. information about each flight, necessary to ensure continued flight safety, and;      2. the current aircraft certificate of release to service, and;      3. the current maintenance statement giving the aircraft maintenance status of  what scheduled and out of phase maintenance is next due. The maintenance  statement may be kept at the operators engineering office: and;     4. all outstanding deferred defects rectifications that affect the operation of the  aircraft,     5. any necessary guidance instructions on maintenance support arrangements. (b) The aircraft technical log system and any subsequent amendment shall be  approved by              DGCA. (c) An operator shall ensure that the aircraft technical log is retained for 36 months  after the          

Tech Record Maintenance

               When an owner/operator arranges for the relevant maintenance organisation to retain  copies of the continuing airworthiness records on their behalf, the owner/operator will  continue to be responsible for the retention of records. If they cease to be the  owner/operator of the aircraft, they also remain responsible for the transferring the  records to any other person who becomes the owner/operator of the aircraft.                Keeping continuing airworthiness records in a form acceptable to DGCA normally means in paper form or on a computer database or a combination of both methods . Records stored in microfilm or optical disc form are also acceptable.                All records  should remain legible throughout the required retention period.  Paper systems should use robust material, which can withstand normal handling and  filing.               Computer systems should have at least one backup system , which should be updated at least within 24 hours of any

Service life-limited components

              The term ‘ service life-limited components ’ embraces:                                          (i) components subject to a  certified life limit after which the components should be retired, and                                          (ii) components  subject to a service life limit after which the components should undergo maintenance  to restore their serviceability.             The current status of service life-limited aircraft components should indicate:                                        i. for components subject to a certified life limit: the component life limitation, total  number of hours, accumulated cycles or calendar time and the number of hours/cycles/time remaining before the required retirement time of the component is reached;                                       ii. for components subject to a service life limit: the component service life limit, the  hours, cycles or calendar time since the component has been restored back to their  servi

Aircraft Continuing Airworthiness Record System

Current status of AD should identify the applicable AD including revision or  amendment numbers. Where an AD is generally applicable to the aircraft or  component type but is not applicable to the particular aircraft or component, then this  should be identified.   AD Status includes the date when the AD was  accomplished, and where the AD is controlled by flight hours or flight cycles it should  include the aircraft or engine or component total flight hours or cycles, as appropriate. Repetitive ADs , only the last application should be recorded in the AD status. The  status should also specify which part of a multi-part directive has been accomplished  and the method, where a choice is available in the AD. Status of current modification and repairs means a list of embodied modification  and repairs together with the substantiating data supporting compliance with the  airworthiness requirements. This can be in the form of a Supplemental Type  Certificate (STC), SB, Structural
