Applied Safety Assessment Workshop in conjunction with Cranfield University
R.G.W. Cherry & Associates are pleased to be co-presenters of the APPLIED SAFETY ASSESSMENT Workshop offered by Cranfield University.
New for 2010, the workshop has been extended from 3 to 4.5 days. It covers the practical aspects of conducting safety assessment in the aerospace sector and takes the form of a series of hands-on tutorials to reinforce the process and techniques involved.
Delegates will carry out exercises on aircraft systems using both hardware and systems drawings. These exercises will then be brought together to show how they can be used in the safety analysis of the aircraft or system as a whole.
The next scheduled presentations of the workshop are 28th June - 2nd July 2010 and 29th November - 3rd December 2010.

Accident Data Analysis Study
The Federal Aviation Administration and Transport Canada have commissioned R.G.W. Cherry & Associates to carry out analyses of accident data with the primary intention of determining trends in the number of accidents, number of fatalities and fatality rates to western world turbojet and turboprop airplanes operating in the passenger or passenger/cargo role. As an integral part of this study the Cabin Safety Research Technical Group Accident Database is to be enhanced to allow on-line access and facilitate linkage with the FAA Lessons Learned Database.
CSRTG Accident Database Enhancements
It is intended to upgrade the CSRTG Accident Database to a web-based version. This will provide additional functionality to the Accident Database, easier access and immediate availability of changes. It will also make linkage with other web-enabled databases possible, including the FAA Lessons Learned Database.
Cost-Benefit Analysis for Installation of Fire Suppression Systems in Cargo Aircraft
The National Transportation Safety Board has recommended that fire suppression systems be installed in the cargo compartments of all cargo airplanes operating under 14 CFR Part 121. Currently, Class E cargo compartments, which are the primary cargo compartment type used in US cargo airplanes, do not require fire suppression systems. In response to this recommendation, FAA has requested that a cost/benefit analysis be carried out relating to the installation of on-board fire detection and extinguishment systems in cargo airplanes. This report contains the results of this analysis and a description of the methodology used.
This report prepared for the US Federal Aviation Administration can now be downloaded from here.
Cabin Crew Fire Training Report
The report on the Training Needs Analysis for Cabin Crew Fire Training, carried out by R.G.W. Cherry & Associates on behalf of the UK Civil Aviation Authority can be downloaded from here.
This Paper reviews cabin crew fire training, visits were made to training organisations and a web site was used to elicit comments from trainers and crew. Fire training in similar environments where evacuation can be difficult e.g. submarines is compared with the aviation situation. Data looking at fire incidents is analysed. Twenty-four recommendations are made which are subjected to a pre-regulatory impact assessment.
The report was launched on 24th April 2009 in an open forum for parties involved in cabin crew fire training at CAA Aviaton House, Gatwick. Click here for the UK Civil Aviation Authority press release on the open forum.
Developments in Integrated Fire Protection
It had been suggested by the Federal Aviation Administration (FAA), with the support of Transport Canada, that a strategy for aircraft enhanced fire protection should be developed by integrating current technologies that are not commonly utilised on transport aircraft.
Transport Canada has requested that an evaluation be made of the feasibility of such an Integrated Fire Protection System and R.G.W. Cherry & Associates are carrying out extensive research on their behalf in this area.
The concept of an Integrated Fire Protection System originates from the potential availability of Nitrogen Enriched Air (NEA) produced by an Onboard Inert Gas Generation System (OBIGGS) primarily intended for fuel tank inerting.
Combined with a water mist system, the available Nitrogen Enriched Air has the potential to be a replacement for Halon 1301 as a cargo compartment fire suppression agent. Furthermore, a Cabin Water Mist System could potentially be cost beneficial if the cargo and cabin systems could “share” elements of the water mist system. There is also the possibility of using the NEA as an on-demand fire suppressant for hidden areas, equipment bays, and wheel wells.
In addition to this, there is also the potential of using the Oxygen-Enriched Air (OEA), as the by-product of the OBIGGS, as part of an emergency oxygen supply for passengers and crew.
This subject has attracted much interest in the aircraft industry and, to this end, an Integrated Fire Protection Task Group (including members from airworthiness authorities, aircraft and equipment manufacturers) has been established. This Group, a subgroup of the International Aircraft Systems Fire Protection Working Group, will provide advice and guidance on future research on this subject.
