The scope of this Airworthiness Notice cover working Hours of Aircraft Maintenance Personnel employed by Maintenance organisations/operators. D. DESCRIPTION: D1. DEFINITION: Nil D2. GENERAL: D2.1 The aviation maintenance system is heavily dependent upon people being able to perform their jobs efficiently. On a number of occasions, Airworthiness Directorate has been reported excessive working hours or shift detailing of individuals involved in aircraft maintenance. The stretched working hours are a potential hazard, which is contrary to Human Performance Limitations. Despite obvious involvement of maintenance personnel in the overall safety of air transport operations, there exist no such limit on the work hours of aircraft maintenance personnel. Additionally, other factors also contribute to concerns over the extended work hours of aircraft maintenance personnel, which leads to making errors, omissions, lapses and failure to notice obvious flaws. D3. APPLICABILITY: D3.1 This Airworthiness Notice is applicable to all local operators, Maintenance Organizations and individuals, who are engaged in aviation related maintenance activities; all local approved organizations involved in aircraft maintenance/ overhaul, aviation training, design, manufacture or repair of aircraft components.

D4.1.2 No shift should be extended through overtime beyond a total of 13 hours. D4.1.3 A minimum rest period of 11 hours should be allowed between the end of a shift and the beginning of the next, and this should not be compromised by overtime. 01/11/2014 Page 2 of 4 AWNOT-082-AWXX-1.0

D4.1.5 A minimum break period of fifteen minutes for first hour plus five minutes for each subsequent hour worked since the start of the work period or the last break.

D4.1.7 Total work, including overtime, should not exceed 60 hours or seven successive work days before a period of rest days. D4.1.8 A period of rest days should include a minimum of two successive rest days continuous with the 11 hours off between shifts (i.e. a minimum of 59 hours off).this limit should not be compromised by overtime. D4.1.9 A minimum of 4 weeks annual leave should be allowed. D4.1.10 A span of successive night shifts should be limited to 6 for shifts of up to 8 hours long, 4 for shifts exceeding 8 hours up to 10 hours long, and 2 for shifts of exceeding 10 hours or longer. These limits should not be exceeded by overtime. D4.1.11 A span of nights shifts involving 12 or more hours of work should be immediately followed by a minimum of two successive rest days continuous with the 11 hours off between shifts (i.e. a minimum of 59 hours off) and this should be increased to three successive rest days (i.e. 83 hours off) if the preceding span of night shifts exceeds three or 36 hours of work. These limits should not be compromised by overtime. D4.1.12 The finish time of the night shift should not be later than 08:00. D4.1.13 A morning or day shift should not be scheduled to start before 06:00, and wherever possible should be delayed to start between 07:00 and 08:00.

This limit should not be compromised by overtime. D4.1.15 Wherever possible aircraft maintenance personnel should be given at least 28 days notice of their routine work schedule. D4.1.16 Training programmes should be developed to increase aircraft maintenance engineers and support staff awareness on the problems associated with shift work. In particular, it is important to draw their attention to the objective trends in risk with a view to increasing their vigilance at points when risk may be high despite the fact that fatigue may not be. It is also important to provide information on how to plan for night work, and to give guidance on the health risks which seem to be associated with shift work, particularly at night. D4.1.17 Aircraft maintenance personnel should be required to report for duty after they have taken adequate rest. 01/11/2014 Page 3 of 4 AWNOT-082-AWXX-1.0
