SUFFICIENT NUMBER OF PERSONNEL
1.Has sufficient staff means that the organisation employs or contracts competent staff, as detailed in the man-hour plan, of which at least half the staff that perform maintenance in each workshop, hangar or flight line on any shift should be employed to ensure organisational stability. For the purpose of meeting a specific operational necessity, a temporary increase of the proportion of contracted staff may be permitted to the organisation by the competent authority, in accordance with an approved procedure which should describe the extent, specific duties, and responsibilities for ensuring adequate organisation stability. For the purpose of this subparagraph, employed means the person is directly employed as an individual by the maintenance organisation approved under Part-145, whereas contracted means the person is employed by another organisation and contracted by that organisation to the maintenance organisation approved under Part-145.
2.The maintenance man-hour plan should take into account all maintenance activities carried out outside the scope of the Part-145 approval. The planned absence (for training, vacations, etc.) should be considered when developing the man-hour plan.
3.The maintenance man-hour plan should relate to the anticipated maintenance work load except that when the organisation cannot predict such workload, due to the short term nature of its contracts, then such plan should be based upon the minimum maintenance workload needed for commercial viability. Maintenance work load includes all necessary work such as, but not limited to, planning, maintenance record checks, production of worksheets/cards in paper or electronic form, accomplishment of maintenance, inspection and the completion of maintenance records.
4.For aircraft base maintenance, the maintenance man-hour plan should relate to the aircraft hangar visit plan as specified in AMC1 145.A.25(a).
5.For aircraft component maintenance, the maintenance man-hour plan should relate to the aircraft component planned maintenance as specified in point 145.A.25(a)(2).
6.The man-hours allocated to the compliance monitoring function should be sufficient to meet the requirement of point 145.A.200(a)(6) which means taking into account the AMC to 145.A.200(a)(6). Where compliance monitoring staff also perform other functions, the time allocated to those functions needs to be taken into account in determining the number of compliance monitoring staff.
7.The maintenance man-hour plan should be reviewed at least every 3 months and updated when necessary.
8.Significant deviation from the maintenance man-hour plan should be reported through the departmental manager to the compliance monitoring manager and the accountable manager for review. It may also be reported through the internal safety reporting scheme. A significant deviation means that there is more than a 25% shortfall in available man-hours during a calendar month for any one of the functions specified in point 145.A.30(d).
9.In addition, as part of its management system in accordance with point 145.A.200, the organisation should have a procedure to assess and mitigate the risks:
(1)if the actual number of staff available is less than the planned staffing level for any particular work shift or period;
(2)if there is a temporary increase in the proportion of contracted staff in order to meet specific operational needs.
