          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,                  ...

Nevertheless, such organisation or certifying staff may  temporarily remove this component for maintenance, in order to improve access...

                                          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.

                        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 mainten...

(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  approv...

               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 han...

              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, to...

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 ...
