Is Fatigue a Concern in MX Operations?
• National Transportation Safety Board (NTSB)– Reduce accidents and incidents caused by human fatigue in the
aviation industry (NTSB Most Wanted)– Review the issue of personnel fatigue in aviation maintenance; then
establish duty time limitations consistent with the current state of scientific knowledge for personnel who perform maintenance on air carrier aircraft (A-97-71)
• Federal Aviation Administration (FAA)– The aircraft maintenance work environment is a leading problem
area for high levels of physical and cognitive fatigue (FAA Fatigue Conference, 2008)

An Example from Industry
“I have been a lead mechanic for over 25 years for the airlines. Have I ever worked tired …or seen others work tired when they shouldn't have? Yes. Do other mechanics, leads and management know about it? Yes. Have mistakes been made due to fatigue? Yes... When errors are made we catch them and repair them and press on with the job….”

Current R&D for Maintenance Fatigue
• Multi-disciplinary workgroup• Develop integrated, scientifically-based, practical
solutions– Short-term (Low Hanging Fruit)– Long-term

Steps to an Effective Training Program
1. Motivate the learner
2. Help the learner diagnose their challenges
3. Empower the learner with knowledge to overcome challenges
4. Reinforce the learning

Step 1 - Motivation: What’s in it for me?
• INDIVIDUAL– Improved quality of life– Increased average sleep times– Fewer physical illnesses
• COMPANY– Reduced absenteeism– Reduced turnover– Reduced morale problems– Fewer accidents and injuries

Step 2 - Diagnosis: Is fatigue an issue for me?
• Most people overestimate their sleep
• Several methods to improve diagnosis– Sleep diary– Symptom checklist– Supplemental incident form

Sleep Log: Example
Your total average hours of sleep this week
(Naps not included):
Your total average number of awakenings this week:
Quality of your sleep on average:
Note: If you are experiencing multiple awakenings (longer than 20 mins) during your sleep period, you may have a sleep disorder and should consult a physician.
This rating is based on a (1 - 5) scale. 1=poor, 5=excellent.
*Caffeine=coffee, tea, caffeinated soda, chocolate, energy drinks, & certain medications
Note: Deduct 30 mins from your total for sleep inertia (the period it takes to wake-up and fall asleep). If you are getting less than 7 hours of sleep on average, you may need to change your sleep habits.Bed Tim

Step 4 – Reinforcement: Promoting Fatigue Awareness at Work
• Utilize international attention to fatigue in aviation to improve awareness and reinforce training
• Utilize available fatigue awareness materials – Calendars– Newsletters– Posters– HFPS

Organizational Implications
• Training is the first step toward addressing job-related fatigue
• Knowledgeable employees are more likely to embrace change if they understand and recognize the effect of fatigue
• Manager training must include guidance on:– How to develop science-based schedules– How to allocate tasks when fatigue is a concern– How to continually evaluate fatigue-related safety
18 18Federal AviationAdministration
World Aviation Training SymposiumApril 27-29, 2010 Orlando, FL
Training Limits
• Fatigue countermeasure training is a low-hanging fruit with substantial benefits, but– it has its limits– it cannot extend human physical and
mental capabilities beyond design limits
• Training is a first step in active fatigue risk management
19 19Federal AviationAdministration
World Aviation Training SymposiumApril 27-29, 2010 Orlando, FL
Future Plans for MX Fatigue Workgroup
• Training program for supervisors• Review of fatigue modeling and scheduling
tools• Return-on-investment assessment for
fatigue management interventions• Operational handbook
– Instructions for implementing a fatigue risk management system
– Tools needed for implementing a fatigue risk management system
