Increasing Crash Survivability
by jeff edwards
I recently spent some time (and money) installing an important upgrade in my Evolution that all Lancair and Evo pilots may want to consider. I have long been interested in installing airbag devices in my aircraft. Such systems have been saving lives in automobiles for nearly three decades. Cirrus began installing airbag seatbelts in its production aircraft more than ten years ago, and I have worked a few accidents where pilots and passengers survived because of these systems. The FAA Alaskan Region studied fatal and serious injuries that occurred in its jurisdiction from 2005 to 2010. It concluded that airbags could have saved up to 50 of 113 lives lost.
In 2011 the NTSB published the results of research on airbag restraints for general aviation in a study titled Airbag Performance in General Aviation Restraint Systems. According to the authors:
In 2003, airbags were first certificated for pilot and copilot seats on general aviation (GA) aircraft, and as of August 2010, they have been installed in nearly 18,000 seats in over 7,000 GA aircraft. In 2006, the National Transportation Safety Board (NTSB) initiated an exploratory case series study to consider airbag performance in GA accidents. The goals of the study were (1) to examine the effectiveness of airbags in mitigating occupant injury in GA accidents, (2) to identify any unintended consequences of airbag deployments, and (3) to develop procedures to assist investigators in documenting airbag systems in future investigations.
The NTSB found the most common cause of death for pilots in GA accidents is blunt trauma; accounting for 86.0 percent of fatalities. The report added:
Aviation airbags can mitigate occupant injuries in severe but survivable crashes in which the principal direction of force is longitudinal. Based upon investigations of 10 accidents, the airbag systems did not cause any negative outcomes when occupants adjusted the restraint systems correctly, and in some cases with airbag deployment, they were associated with reductions in the severity of occupant injuries.
This past year AmSafe announced a universal airbag seatbelt kit that may be installed in many different aircraft. Priced at $2580, AmSafe says its Seatbelt Airbag System (SOARS) is "a universally adjustable lapbelt airbag restraint system designed to mitigate head and torso injury in aircraft crash conditions.
With over a billion hours of logged service, AmSafe Airbag Systems are utilized in commercial aircraft, business jet and turboprop aircraft; as well as general aviation to protect pilots, co-pilots and passengers. SOARS is a very affordable, yet significant enhancement for general aviation occupant protection. Each SOARS kit includes a complete airbag restraint system for both the Pilot & Co-Pilot seats, replacing the original pilot and co-pilot 2 or 3-Point standard restraints.”
I found the AmSafe booth in Hangar D at Airventure this year and after talking to Mr. Jim Crupi, their representative, I decided to purchase the kit. It arrived complete with a very comprehensive set of instructions. I reviewed them thoroughly before installing the two seatbelt sets. Installation was straightforward using the mannequin supplied in the kit.
