Foreign Object Damage (FOD) in Aviation
*FOD costs the civil aviation industry 3-4 Billion dollars each year
![Page 7: Falling objects: Engaging the ”man-in-the-loop” to achieve real safety improvement](https://reader033.vdocuments.us/reader033/viewer/2022060110/5559dd4dd8b42a39498b48a3/html5/thumbnails/7.jpg)

Civil aviation describes the FOD program as a two phase process: • Avoidance of foreign objects • Removal of foreign objects
FOD program activities: • FOD walkdowns • ”Good housekeeping” activities • Reporting and investigation • Compiling data and trend analysis
![Page 8: Falling objects: Engaging the ”man-in-the-loop” to achieve real safety improvement](https://reader033.vdocuments.us/reader033/viewer/2022060110/5559dd4dd8b42a39498b48a3/html5/thumbnails/8.jpg)

The FOD program today is an integrated part of the overall safety management system • Safety culture/climate
But what about identification of foreign objects? • Everyone’s responsibility

A systems perspective
• ”Since both failures and successes are the outcome of normal performance variability, safety cannot be achieved by constraining – or eliminating it.”
• Normal Accident Theory – (Perrow, 1984) • High Reliability Organizations (Rochlin et al.,
1987) • Resilience Engineering (Hollnagel et al., 2006)
• Safety management cannot be based on a reactive approach alone
![Page 14: Falling objects: Engaging the ”man-in-the-loop” to achieve real safety improvement](https://reader033.vdocuments.us/reader033/viewer/2022060110/5559dd4dd8b42a39498b48a3/html5/thumbnails/14.jpg)
Understanding the nature of systems
• How systems are designed and developed to operate in an ”expected” environment
• How they evolve in response to the environment
• Based on our limited mental models – why a particular risk assessment might be limited
• Instead, expecting that challenges to system performance will occur – because systems evolve
![Page 15: Falling objects: Engaging the ”man-in-the-loop” to achieve real safety improvement](https://reader033.vdocuments.us/reader033/viewer/2022060110/5559dd4dd8b42a39498b48a3/html5/thumbnails/15.jpg)
The problem with models
• ”All models are wrong” – Jay Forrester • All models are simplifications of reality
• Includes our system of rules and regulations • Models are based on our limited cognative
capacity • Short-cuts • Rules-of-thumb
![Page 16: Falling objects: Engaging the ”man-in-the-loop” to achieve real safety improvement](https://reader033.vdocuments.us/reader033/viewer/2022060110/5559dd4dd8b42a39498b48a3/html5/thumbnails/16.jpg)
Safety Management Systems
• Based on an ideal or rational view of an organization
• Where functions, roles and responsibilities are clearly defined ”for people” according to specified organizational goals, and as a result, the organization is designed to ”behave” in a rational way
• A prescriptive approach ending up with a normative organization against which practices can be measured or assessed

Swiss Cheese Model – Reason (1990)
• Focus and the Man-in-the-loop in MTO and on HSE-culture.
• Need to involve those who feel the problem in the bodies – those on the shop floor.
• Last line of defence

Organizational culture (Schein, 2004)
• Culture – a dynamic phenomenon that surrounds us at all times • Constantly enacted and created by our interaction
with others and shaped by leadership behavior • Creates a set of social structures, routines, rules and
norms that guide and constrain behavior • The dynamic processes of culture creation and
management are the essence of leadership

Culture and leadership
• Two sides of the same coin • Culture decides what defines leadership but
leaders create and manage culture • Leadership creates and changes culture, while
management and administration act within culture
• Culture is the result of complex group learning processes that are only partly influenced by leader behavior

Culture drives our thinking and actions
• Observed behavioral regularities when people interact
• Group norms • Espoused values • Informal ”rules of the game” • Habits of thinking, mental models and linguistic
paradigms – cognitive frameworks

• Relative priorities • Alignment between espousals and
enactments • Internal consistency • Shared cognitions or social consensus • Motivation for climate perceptions: social

How do leaders embed their beliefs, values and assumptions
• Primary embedding: • What leaders pay attention to, measure and control • How leaders react to critical incidents and
organizational crisis • How leaders allocate resources • Deliberate role modeling, teaching and coaching • How leaders allocate rewards and status • How leaders recruit, select, promote and
excommunicate 05-11

High Reliability Organizations (HROs)
• Creating a supporting organizational culture • Creating a ”learning environment” • Mindfulness
• Knowing (Education and training) • Sensemaking • Seeing (Noticing) • Responding (Reporting) • Taking action

Key points
• Targeting human error no longer target • Safety is the presence of something not the
absence of something • Attempting to fix unreliable human behavior
by: • Automation • More procedures and barriers • Increased monitoring
• Only people have adaptive capacity
![Page 36: Falling objects: Engaging the ”man-in-the-loop” to achieve real safety improvement](https://reader033.vdocuments.us/reader033/viewer/2022060110/5559dd4dd8b42a39498b48a3/html5/thumbnails/36.jpg)
Using the operators
• Operators, and their deep understanding of an application area is an important source of resilience – expertise in action
• Two main sources of resilience • Picking up the faint signals when ”things are going
wrong” • Being able to develop resources that can adapt ”on
the fly” • Identify potential dangers
