I welcome any additions, corrections, or suggestions.- Fe el free to contact me directly off list.- Thanks,=0A-=0AJeff Linebaugh =0Ajefflinebaugh@bellsouth.net=0A-=0A-=0AThe safety seminar was well at tended.- More than 25 people took time out of their AirVenture experience to participate. It was a diverse group: builders and flyers with F1s, Harm ons, and =93hybrids=94, geographically varied, experienced and not so. We h ad a wealth of knowledge and breadth of experience not often see in a flyin g group. It was a great opportunity to put faces with names and get to know other Rocketeers.=0A-=0AWe started with a short review of Rocket acciden ts. Most plaguing were several accidents that occurred =93maneuvering=94 cl ose to the ground and/or while performing aerobatics, with no aircraft anom alies found. There were also two forced landings. Compared to RV-type aircr aft, we evidently have a greater chance of falling prey to the temptations of low level aerobatics.=0AWe then passed on lessons learned and experience s. Some of the topics were:=0A=B7------- Spins and aerobatics =0Ao------ Differences with a passenger/aft CG ----- -- =0Ao------ Hammerheads, and the risks of inadvertent spi n entry=0Ao------ Differences between upright and inverted spin recoveries=0Ao------ Differences between learning aerobatics i n a Decathlon or Pitts and flying them in a rocket=0A=B7------ - Engine failure glide ratios: counter weighted propellers vs. non counte r weighted, different props and rpm settings and their affect on glide perf ormance=0A=B7------- Low altitude engine failures: when not t o turn back to the runway=0A=B7------- Inverted oil systems: risks and maintenance requirements=0A-=0AWe stand much better odds of imp roving personal safety as a group than as a bunch of individuals. Learning from each other=92s experiences, and using our varied talents and resources will reap benefits for everyone. Overall, communication is the key in iden tifying and solving problems. To this end, Mark Frederick volunteered to he lp set up a private forum for Rocket owners only, aimed at sharing useful a nd positive information (in contrast to the open, and often misused Matroni cs forum). =0A-=0ASeveral suggestions were made by the group in the inter est of safety. Suggestions that fell into the area of flying and operating the aircraft:=0A=B7------- Identify high risk practices and d evelop a list of procedures and maneuvers to avoid. For instance:=0Ao-- ---- Low-level aerobatics=0Ao------ Showing off or perf orming maneuvers at the spur of the moment without forethought, proper trai ning or practice=0Ao------ Performing high pitch angle/low airs peed maneuvers (for instance, hammerheads) without understanding the risks of inadvertent spin/inverted spin entries and recovery procedures=0Ao-- ---- Over-the-top aerobatics or spins with an aft CG/heavy weight p assenger =0Ao------ Engine hot starts with high throttle settin gs and/or locked brakes resulting in nose-overs=0A=B7------- Encourage owners to fly with one another (with ego=92s checked at the door) to observe each other=92s good and bad habits=0Ao------ Highli ghts differences between airframes and helps start an exchange of informati on=0A=B7------- Develop a personal safety creed to make a con scious decision on the ground to avoid high risk situations and actions. He lp support others in adhering to their safety creed. For instance:=0Ao- ----- I will not perform low level aerobatics or aggressive maneu vers below XXXX=92 AGL=0Ao------ I will not fly VFR with ceilin gs less than XXXX=92, XXXX=92 in mountainous terrain=0Ao------ I will identify and fix known aircraft malfunctions promptly=0Ao--- --- I will always take X minutes to perform a proper preflight inspec tion=0Ao------ I will not fly when impaired physically in any w ay=0Ao------ Etc=85- =0AFrom the Maintenance and Airworthines s side of the equation:=0A=B7------- Identify maintenance are as to pay closer attention to=0Ao------ Re-torque gear legs at oil changes=0Ao------ Engine baffling=0Ao------ Tai lwheel spring attach bracket=0Ao------ Control linkages, rod-en ds and use of washers=0Ao------ Engine mounts=0Ao---- -- Empennage and spar attach points- =0A=B7------- Real ize the additional strain placed on aircraft used regularly for aerobatics and increase inspection requirements=0A=B7------- Have an exp erienced and concerned independent person look over your aircraft=0Ao-- ---- the builder may have a prejudiced eye when it comes to inspect ing and maintaining their own aircraft=0Ao------ a non-builder may not have the experience or know how to maintain their own aircraft=0Ao ------ It may be hard on the pride, but having a critical but c onsiderate individual inspect our airplanes may help point out deficiencies .. In any case, it helps start an exchange of information.=0Ao---- -- Put together a =93for fun=94 fly-in competition where we all look at each other=92s planes to- see who can find the most items that could be improved=85?=0A-=0AConclusion:- It was worthwhile time spent with other Rocketeers.- The session was well received and most came away feeling po sitive and better informed. Many expressed an interest in continuing with s imilar gatherings and new measures focused on Rocket safety. We fly, or are building to fly one of the best sport aircraft on the planet. To be able t o maximize the thrill of flying this great aircraft safely, and be able to encourage others to do the same would be a great goal!=0A-=0AJeff Linebau gh=0Ajefflinebaugh@bellsouth.net=0A-=0A -=0A -=0Ahttp://www.matronics ================0A=0A=0A ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rocket-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Rocket-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rocket-list Browse Digests http://www.matronics.com/digest/rocket-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
