Aircraft Maintenance Technology - 45

EASA should create root cause analysis (RCA) support that is
specifically focused on procedural non-compliance. The research
deliverables should help users to ask more and better questions
related to procedural non-compliance. The RCA research results
should make it easier for industry safety practitioners to effectively identify causes of procedural non-compliance and rapidly
implement solutions.

Challenge 3: Design and Deliver Training for Resilient
Behavior when Procedures Do Not Match Situations
There cannot be a specific procedure for every action in a complex
system. The group recommended that government and industry
focus on increasing human and systemic resilience. This means
that training regarding human performance variabilities in complex
operational conditions must go beyond procedural compliance.
Programs must prepare the human to "cope" and to adapt when
procedures do not offer solutions/actions match to a situation.
The committee recommended that EASA facilitates the production of training material to effectively inform audiences that
procedure following does not automatically equate to safety.
Safety emerges from systematic interactions (people, artefacts,
training, etc.) and consequently increased focus should be aimed
at adaptation skills and defensive operating techniques, ultimately
fostering individual and team resilience.

Challenge 4: Design Guidelines and Use of Electronic
Checklists (ECL) for Maintenance Tasks
ECLs for maintenance personnel lack structured human factors
design approach and often contradict well established design
philosophies of the flight deck, e.g. the use of color.

The committee recommended that EASA investigates how
properly designed ECL for maintenance personnel could help
to provide the same benefits as ECL for flight crews, and as a
consequence, reduce human error of maintenance personnel.
The committee recommended that EASA creates human factors design considerations for ECL for maintenance personnel
which are consistent with established design guidelines for ECL
for flight crews.

CONCLUSIONS
The small multi-disciplinary team felt that the list of recommendations was short, yet comprehensive. In summary, write
excellent procedures, foster an industry culture to use the procedures, seek to understand why a procedure was not used,
deliver the procedure using an appropriate methods and technology and train the human to cope when a procedure is not
available or relevant.
The recommendations described herein are but one small
example of the advice that industry/government panels can offer
to all National Aviation Authorities. US Industry/FAA examples
include committees like the Commercial Aviation Safety Team
(CAST) and the General Aviation Joint Steering Committee
(GAJSC). Internal committees like the FAA AVS Human Factors
Coordinating Committee (AVS HFCC) is comprised of Human
Factors personnel in Flight Standards and Aircraft Certification.
Advisory groups are extremely valuable to help governments
manage safety. Multidisciplinary groups offer a broad perspective that can provide the best thinking of government, industry,
and academia. Such groups can provide understandable and
actionable advice.
