4.4.2 Experience levels
Except in the case of incumbent supervisory/management personnel already employed in an organi-zation introducing a new aircraft type, where additional manufacturer or other qualified support may be required during the introductory and early operational phases, the experience level require-ments at Appendix 5D1-3 should be applied.
4.4.2.1 Unlicenced and recently licensed maintenance personnel
Where organisations employ a mix of licenced and unlicenced or recently licenced personnel, the proportion of personnel having Certificate of Release to Service (CRS) privileges to others should be sufficiently high to ensure adequate supervision of work is provided at all times.
4.4.2.2 Trainee aircraft maintenance engineer/technician/mechanic
Where trainees are sponsored or employed directly, the requirements for unlicensed and recently licenced maintenance personnel equally applies. In addition, there will be a documented training plan that includes:
a) Formal training – must hold basic educational qualifications for entry into regula-tor approved maintenance training course(s) in respect of the licence categories desired. Training must be provided by an approved training organisation.
b) On-the-job training – must be relevant and provide adequately supervised experience.
4.4.3 Avoidance of fatigue in maintenance personnel
Other than any specific labor laws that may be applicable locally, maintenance personnel are not
regulated by duty hour limitations. The following should be applied to all engineering staff as a minimum standard:
4.4.3.1 Total work period
Total work periods should not exceed 12 hours in any 24-hour period. Where, exceptionally, it is essential that the working period is extended; the Head of Maintenance should approve it on a case-by-case basis.
4.4.3.2 Night Shifts
Where shifts are regularly rostered with a heavy maintenance workload to be completed through the night, the length of the duty period may be reduced from the 12 hour maximum.
Ideally, if night maintenance is necessary, the bulk of work should be completed by the shifts on duty up to midnight with the residue completed by a swing shift covering the period from approximately 2300 to 0700 hrs.
4.4.3.3 Rest
Each full working shift should be followed by a minimum 8-hour rest period. When working a 24-hour split shift on line operations, at least 6 hours rest should be provided excluding travel. The entitlement for days off should be a minimum of 7 per month of which at least 4 should be in a minimum of 2-day periods. When the location or climate is arduous then this should be increased to minimize fatigue.
4.4.3.4 Remote camps
On locations such as seismic camps, where it is not feasible to provide other than the bare accom-modation necessities, a regular “time on site, time off site” routine should be set up to ensure that maintenance personnel working under these conditions do not stay in the field for prolonged peri-ods. The minimum recommended ratio of time on site to time off site is considered to be 2:1 with a maximum period on site not to exceed 2 months.
4.5 Maintenance requirements
4.5.1 Quality assurance & quality control
Quality Assurance requirements are given at paragraph 3.4. Quality Control procedures are nor-mally a regulatory requirement, and should adopt a form similar to those expressed in JAR Ops 1/ JAR 145. However, where there is an absence of regulatory control in this respect, the requirements expressed in paragraphs 4.5.2 and 4.5.3 should be satisfied by all operators/maintenance organisa-tions on contract to the OGP Member.
