This two day seminar is a follow-on to the previous "OVERVIEW OF FAA CERTIFICATIONS: TCs STCs PMAs TSOs" seminar for those who have more available time and need a deeper understanding. The first day addresses advanced STCs and PMAs samples and open discussion.
The second day is an overview of Functional Hazards Assessment- System Safety Analyses. It is for persons new to the subject who need to quickly understand the process. The FAA is requiring an FHA/SSA on essentially all new certifications. Like many specialty skills, System Safety Analyses have their own language with many abbreviations that can make the subject difficult to learn. The seminar starts at ground zero. We use simple language at first and slowly develop a basic understanding. Attendees leave the seminar with a top level overview of the process and purpose. Attendees will be able to read an FHA/SSA report and be able to perform simple basic analyses. Seminar material addresses four elements; Functional Hazards Assessment (FHA), Fault Tree Analyses (FTA), Failure Modes and Effects Analyses (FMEA) and Common Cause Analyses (CCA).
.
It takes some time to become an expert at this, but the seminar will lead attendees in the right direction for a much quicker start. Here are some of the topics presented in the two days:
By the way, our motto is...
"DON'T SOUND STUPID IN SSA MEETINGS !"
The seminar is periodically conducted in Las Vegas providing attendees a full two days of informative aviation sessions. As a bonus attendees have access to the relaxation of evening entertainment and numerous weekend outdoor activities of the Las Vegas vacation area.
ATTENDEE COMMENTS
"I have been to several aviation seminars in (aviation city) but this one is far superior."
"...the seminar makes System Safety Analyses an understandable subject…"
"We should have taken your seminar at the start of our last program."
SEMINAR DETAILS...
1. ADVANCED STCs This is a follow of the previous "OVERVIEW OF FAA CERTIFICATIONS: TCs STCs PMAs TSOs" seminar where the class goes into more examples, exercises and open discussion regarding STCs.
2. ADVANCED PMAsThis is a follow of the previous "OVERVIEW OF FAA CERTIFICATIONS: TCs STCs PMAs TSOs" seminar where the class goes into more examples, exercises and open discussion regarding PMAs.
1. WHAT IS A SYSTEM SAFETY ANALYSIS (SSA)System Safety Analyses is the broad subject that is sometimes referred to as “1309” or “reliability analyses” or “10 to the minus ninth stuff” among other names. The seminar explains the elements involved in an SSA effort. It consists of three elements; Functional Hazards Assessment (FHA), Failure Modes and Effects Analyses (FMEA) and Fault Tree Analyses (FTA). SSAs performed early in the design phase are usually called Preliminary System Safety Analyses or PSSAs.
2. WHAT IS A FUNCTIONAL HAZARDS ASSESSMENT (FHA)Part of an SSA is an analysis of “loss of functions” as opposed to “loss of components”. The seminar explains what a “function” is. An example is “loss of altitude information to the pilot” or “loss of breathable atmosphere in an airplane”. The seminar explains how to classify these losses when “things go wrong” by how serious a loss might be. It is typical to classify losses into 5 groups; No Safety Effect, Minor, Major, Hazardous and Catastrophic.
3. HOW TO DO A FAILURE MODES AND EFFECTS ANALYSIS (FMEA)A Failure Modes and Effects Analysis is a component by component analysis of a design. In a sense it says “if this breaks what happens” and “if that breaks what happens”. There are industry accepted methods of doing this FMEA and attendees will learn them.
4. WHEN AND HOW TO CREATE FAULT TREES (FTAs)Sometimes it is necessary to organize a sequence of failures into a diagram. This is called a fault tree. It can also calculate the probability of something “bad” happening. Students will learn the basics of fault trees.
5. HOW DO ALL THE ABOVE COMBINE INTO A COMPLETE SSAA complete System Safety Analysis has several elements. It combines all the above FHA, PSSA, FMEAs and FTAs. Sound like alphabet soup? It really isn’t once you see a few examples. Attendees will learn what each of these pieces does for the overall SSA.
6. HOW DO I PERFORM A COMMON CAUSE ANALYSIS CCAA complete System Safety Analysis also includes a Common Cause Analysis. It is different because it is qualitative as opposed to "the 10 to the minus ninth" qualitative analyses above. A Common Cause Analysis has three sub elements; a Particular Risk section, a Common Mode section and a Zonal section. The class will perform a simple Common Cause Analysis.
7. FAA REGULATIONS 23.1309 AND 25.1309The FAA has certain regulations for System Safety Analyses but they are not terribly reader friendly. The class will review the key FAA regulations.
8. FAA AND INDUSTRY REFERENCE MATERIALSThere are some FAA and industry documents that are somewhat universally accepted for doing System Safety Analyses. The class will review the key ones which are the Society of Automotive Engineers ARP 4761 document and industry databases for historical reliability of components. The ARP 4761 document is a wonderful reference but impossible to learn how to perform SSAs by reading it. There are also FAA documents called “Advisory Circulars” that are reviewed.
9. COMMON ERRORS AND PITFALLS IN SSAsDesign programs that try to do the above FHA PSSA SSA FMEA FTA (wow!) often have common problems. The seminar will discuss to common errors and pitfalls and how to best avoid them. The biggest two pitfalls are not understanding SSAs and starting the effort too late.
10. SOFTWARE THAT HELPS FHAs FTAs FMEAsThere are some software tools that are available that can help a design effort perform these analyses. A simple analysis can all be done by hand. However a complex project can be much more organized by using specific software. Like many other skills, software cannot help if a person does not understand the basics. A quick look at what is available on the software market.
11. HOW TO READ AND REVIEW AN SSA REPORTSince this class is an overview, many attendees find themselves in a managerial position where they have to assign or contract out a System Safety Analysis. Finally the report is presented and it looks like Greek. The seminar class will review a real SSA report and determine if it contains the proper elements.
12. BONUS: HOW TO STAY AWAKE IN A “1309” SEMINARIf you are taking this session literally you need to lighten up!... but... The Drake Group has made a conscious effort to make the material as interesting as possible. We even (in good natured jest) make fun of stupid applicants, grumpy FAA personnel, "talk-the-talk" seminar leaders and "out-of-town-in-Vegas" seminar attendees. After all, two days of our lives in a seminar should be informative first… but pleasant as possible also.
