1 Session 6 Documenting the Cabin
Overview Focus of the analysis Documentation process Systems Equipment Cabin conditions Examples Points to remember Q&A Practical exercise #2 2
Documenting the Cabin Key part of investigation process Examine & record condition of Relevant aircraft systems Safety & emergency equipment Cabin in general Floor, ceiling panels, seats, etc. 3
Focus of Analysis Reasons for failure, damage or malfunction of Structures Systems/equipment or their components Evaluate how they affected Ability of cabin crew to carry out duties & responsibilities Survivability of occupants 4
Documentation Process Process may require testing of parts Cabin documentation includes Pertinent manufacturer information Model/part numbers for components e.g. seats, seat belts, slides Use tables to facilitate on-site tabulation of systems or equipment data may be included in report 5
Example of Tabulation of Exit & Slide data Door Exit condition Girt bar Slide condition Slide inflation Power assist Other 1 Right Found open. Burn damage on bustle. Handle position 11:00. Attached to door. Handle position 11:00. Found partially deployed Gauge indicated pressure bottle was low or discharged (red). Gauge indicated pressure bottle was low or discharged (red). Exit area burned out. Sill height 7 11. Aircraft leaning approx. 7 degrees to right 6
Documenting Specifics Systems, equipment and conditions to document depend on type of occurrence Fire on board vs. turbulence vs. evacuation Templates in Appendices to Chap 5 of Doc 10062 Provide specific detailed guidance 7
Need to document Example: Evacuation Exits Assisting evacuation means Aircraft/cabin systems Safety & emergency equipment Conditions of the cabin 8
Exits, Assist Evac Means, Systems For systems listed in App C to Chap 5, record Presence Condition failed or damaged, serviceable and/or worked normally Part/serial number Why? Evaluate if systems were useful in managing evacuation or increasing survivability of occupants Determine if systems worked as intended and, if not, determine reason 9
Exits, Assist Evac Means, Systems Exits & assisting evacuation means Evacuation alarm system Comm systems & signalling panels Lighting systems Emergency signalling system 10

Safety & Emergency Equipment For equipment listed in App C to Chap 5, record Presence Condition Failed or damaged, or serviceable and/or worked normally Part/serial number of equipment Why? Evaluate type of equipment available Assess if it was useful or hindrance in managing evac or increasing survivability of occupants 16
Safety & Emergency Equipment Analysis should determine if Required equipment was available, accessible and functional Instructions on how to use equipment were effective Additional equipment would have been helpful not found on board 17
Examples of Equipment Protective breathing equipment Emergency flashlight Megaphone Survival kit Child restraint systems Equipment suited to the likely environment e.g. arctic gear 18
Halon Fire Extinguisher Found in Overhead Bin Above Seats 1A & 1C 19
Unbroken Lanyard on One of the Unpackaged PBEs 20
Life Jacket Stowage 21
Conditions of the Cabin For conditions in cabin listed in App C to Chap 5, record Presence Condition Failed or damaged, serviceable and/or worked normally Part/serial number Why? Evaluate reason for failures/damage How this impacted survival of occupants including injuries sustained Affected their ability to evacuate aircraft 22
Items in Cabin Conditions Floor structure & panels Carpets Insulation Ceiling & sidewall panels PSUs Overhead bins & closets Latching mechanisms Bulkheads & class dividers Tray tables Passenger seats Floor fittings & seat tracks Passenger restraints Cabin crew seats Cabin crew restraints Carry-on baggage 23
What to Look For Deformation/breaches in cabin structure Floor disruptions Evidence of injuries Blood stains Dents or cracks on side panels, ceiling or other Damage or stains on carpets such as bodily fluids which may indicate injuries Seat & restraint mechanism failure incl. seat track attachment Location of upset/damaged seats Seat belts Tray table deployment Condition of stowage bins Signs of flame propagation on insulation materials 24
