    2. OVERVIEW What is a 16G seat? Part 25 Large Transport Category 16G 10 Yaw/Forward Test Floor Deformation (Pitch & Roll) 14G 60 Pitch (Download) Test No Floor Deformation Part 23 Normal, Utility, Acrobatic 21G Pax Seats & 26G Crew Seats Same Yaw Requirements 15G 60 Pitch (Pax) & 19G 60 Pitch (Crew)

    3. FACILITIES Sled Tests Decelerator vs. Accelerator Facilities ATDs (Anthropomorphic Test Device/Dummy)

    4. VIDEO Over In A Blink Of An EyeAlmost Entire Event Occurs In About 0.100 Sec. High Speed Film/Video 1000 Frames Per Second

    5. PASS/FAIL CRITERIA 10 Yaw/Forward Test Demonstrates Structural Integrity of: Seat Structure Aircraft Attachment (Seat Tracks/Floor Fittings) Restraints Bulkheads (Side Facing Seats/Divans) Demonstrates Retention Of Occupant In The Seat Restraints Remain On The Occupant Survivable Injury Criteria

    6. PASS/FAIL CRITERIA Injury Criteria Spine (Lumbar) Loads Less Than 1500 lbs Head Impact Criteria (HIC) Less Than 1000 Units Tests Determine Head Trajectory Shoulder Harness Loads 1750 Lbs. Single/2000 Lbs. Dual Femur Loads Less than 2250 lbs

    7. MONUMENTS Head Trajectory Occupant Movement Envelope (OME) Determine ATD Position Determine Head Strike Potential Data Supplied By Seat Manufacturer Data Supplied By Aircraft Manufacturer 5th thru 95th Percentile Female/Male

    8. UPHOLSTERY Dress Covers Slickness Concern For Submarining Sliding Out From Under The Lap Belt Typical Fabrics & Leathers Are OK Changes Made by EO or Drawing & 8110-3 Flammability Certification

    9. UPHOLSTERY Cushions Amplify Spine Loads Critical To Spine Load Certification Requires Engineering Data To Change Replacement is a Modification to a TSO Article Some Aircraft: Seats Not TSOd, but Type Design Data

    10. MODIFICATIONS Modifying A TSO Article Reference AC 21-25a Restraints are Part of TSO-C127a Certification Upholstery Is Part Of TSO-C127a Certification Label Required To Indicate Modified IAW Engineering Data Seat Manufacturers Fees for TSO Label FAA/Industry Committee Seat Cushion & Restraint Replacement Policy

    11. FAA DRAFT POLICY Restraint Replacement Side by Side Testing in Rigid Seats Compare Restraint Webbing Loads (+/- 6%) Max Head Excursion (+/- 1.0) Cushion Replacement Monolithic (Single Layer Single Density) Structural Compression Test Foam Characteristics Compare Data to a Set of Curves

    12. ALTERNATIVE APPROACH Foam Replacement (styling changes allowed) Cessna Models 525 CitationJet (ACES STC To Replace) 750 Citation X (ACES Engineering Data) 560XL Excel (Similar to 750) Sovereign (Similar to 750) Gulfstream GV ACES Engineering Data For Most Pax Seats Falcon 2000 Engineering Data For Jump Seat Only

    13. BULKHEAD/AIRBAG TESTS

    14. INFLATABLE RESTRAINTS Improved HIC Results AMSAFE Paving the Way Lap Bags Shoulder Restraint Bags Both Solve Head Impact Problems and/or Improve Crashworthiness

    15. INFLATABLE RESTRAINTS Adam Aircraft First New Type Certificated Aircraft to Offer Inflatable Restraints A500 Inline Twin Excellent Results Various Aircraft Manufacturers Providing Retrofit Inflatable Restraints

    16. VIDEO 26 G Comparison Simulated Cockpit Lap Bag 26G Shoulder Bag Restraint Development

    17. MISCELLANEOUS Seat Supplier vs. Installer Responsibilities Seat Suppliers Know Seats And Sell Seats Installation Is The Responsibility Of The Repair Station HIC Is Installers Responsibility Installer Responsible To Maintain The Integrity Of the TSO Article

    18. MISCELLANEOUS Refurbs / Used Aircraft Purchase If 25.562 is in the Cert Basis Has aircraft ever been re-ragged? Were cushions changed? OEM Agreements With FAA for Dynamic Tested Seats But Not in the Cert Basis TC Data Sheet Side Facing Divans Barriers Are Part Of The Restraint System
