3.  
In the case of commercial air transport, an operator should publish guidance to maintenance and flight personnel and any other personnel performing pre-flight inspection tasks, as appropriate,  defining responsibilities for these actions and, where tasks are contracted to other organisations, how their accomplishment  is subject to the quality system of MCAR-M.712. It should be demonstrated  to CAD that pre-flight inspection personnel  have received appropriate training for the relevant pre-flight inspection tasks. The training standard for personnel performing the pre-flight inspection should be described in the operator’s continuing airworthiness management exposition.

AMC M.301 - 2- Continuing airworthiness tasks
In the case of commercial air transport the operator should have a system to ensure that all defects affecting the safe operation of the aircraft are rectified within the limits prescribed by the approved minimum equipment list (MEL) or configuration deviation list (CDL) as appropriate. Also that such defect rectification cannot be postponed unless agreed by the operator and in accordance with a procedure approved by CAD.
In the case of commercial air transport or large aircraft, a system of assessment should be in operation to support the continuing airworthiness  of an aircraft and to provide a continuous analysis of the effectiveness of the MCAR-M Subpart G approved continuing airworthiness management organisation’s defect control system in use.
The system should provide for:
(a)
significant incidents and defects: monitor   incidents and defects that have occurred in flight and defects found during maintenance  and overhaul, highlighting any thatappear significant in their own right.

(b)
repetitive incidents and defects: monitor on a continuous basis defects occurring in flight and defects found during maintenance and overhaul, highlighting any that are repetitive.

(c)
deferred and carried forward defects: Monitor on a continuous basis deferred and carried forward defects. Deferred defects are defined as those defects reported in operational service which are deferred for later rectification. Carried forward defects are defined as those defects arising during maintenance which are carried

forward for rectification at a later maintenance input.

(d)
unscheduled  removals  and system  performance:  analyse unscheduled component removals  and  the  performance  of  aircraft  systems  for  use  as  part  of  the maintenance programme efficiency.

When deferring or carrying forward a defect the cumulative effect of a number of deferred or carried forward defects occurring on the same aircraft and any restrictions contained in the MEL should be considered. Whenever possible, deferred defects should be made known to the pilot/flight crew prior to their arrival at the aircraft.
AMC M.301 - 3- Continuing airworthiness tasks
The owner or the MCAR-M Subpart G approved continuing airworthiness management organisation as applicable should have a system to ensure that all aircraft maintenance checks are performed within  the limits prescribed by the approved aircraft maintenance programme and that, whenever a maintenance  check cannot  be performed  within the required time limit, its postponement is allowed in accordance with a procedure agreed by CAD.
AMC M.301 - 4- Continuing airworthiness tasks
The operator or the contracted MCAR-M Subpart G approved organisation as applicable should have a system to analyse the effectiveness of the maintenance programme, with regard to spares,  established  defects, malfunctions  and  damage,  and to amend  the maintenance programme accordingly.
AMC M.301 -5- Continuing Airworthiness Tasks
Operational directives with a continuing airworthiness impact include operating rules such as extended twin-engine operations (ETOPS) / long range operations (LROPS), reduced vertical separation minima (RVSM), MNPS, all weather operations (AWOPS), RNAV, etc.
