Several people asked for a summary of our Rocket Safety Seminar at Oshkosh.
Were it is in not so short form. I welcome any additions, corrections, or
suggestions. Feel free to contact me directly off list. Thanks,

The safety seminar was well attended. More than 25 people took time out of
their AirVenture experience to participate. It was a diverse group: builders
and flyers with F1s, Harmons, and hybrids, geographically varied,
experienced and not so. We had a wealth of knowledge and breadth of
experience not often see in a flying group. It was a great opportunity to
put faces with names and get to know other Rocketeers.
We started with a short review of Rocket accidents. Most plaguing were
several accidents that occurred maneuvering close to the ground and/or
while performing aerobatics, with no aircraft anomalies found. There were
also two forced landings. Compared to RV-type aircraft, we evidently have a
greater chance of falling prey to the temptations of low level aerobatics.
We then passed on lessons learned and experiences. Some of the topics were:
* Spins and aerobatics
o Differences with a passenger/aft CG
o Hammerheads, and the risks of inadvertent spin entry
o Differences between upright and inverted spin recoveries
o Differences between learning aerobatics in a Decathlon or Pitts and
flying them in a rocket
* Engine failure glide ratios: counter weighted propellers vs. non
counter weighted, different props and rpm settings and their affect on glide
performance
* Low altitude engine failures: when not to turn back to the runway
* Inverted oil systems: risks and maintenance requirements
We stand much better odds of improving personal safety as a group than as a
bunch of individuals. Learning from each others experiences, and using our
varied talents and resources will reap benefits for everyone. Overall,
communication is the key in identifying and solving problems. To this end,
Mark Frederick volunteered to help set up a private forum for Rocket owners
only, aimed at sharing useful and positive information (in contrast to the
open, and often misused Matronics forum).
Several suggestions were made by the group in the interest of safety.
Suggestions that fell into the area of flying and operating the aircraft:
* Identify high risk practices and develop a list of procedures and
maneuvers to avoid. For instance:
o Low-level aerobatics
o Showing off or performing maneuvers at the spur of the moment without
forethought, proper training or practice
o Performing high pitch angle/low airspeed maneuvers (for instance,
hammerheads) without understanding the risks of inadvertent spin/inverted
spin entries and recovery procedures
o Over-the-top aerobatics or spins with an aft CG/heavy weight
passenger
o Engine hot starts with high throttle settings and/or locked brakes
resulting in nose-overs
* Encourage owners to fly with one another (with egos checked at the
door) to observe each others good and bad habits
o Highlights differences between airframes and helps start an exchange
of information
* Develop a personal safety creed to make a conscious decision on the
ground to avoid high risk situations and actions. Help support others in
adhering to their safety creed. For instance:
o I will not perform low level aerobatics or aggressive maneuvers below
XXXX AGL
o I will not fly VFR with ceilings less than XXXX, XXXX in
mountainous terrain
o I will identify and fix known aircraft malfunctions promptly
o I will always take X minutes to perform a proper preflight inspection
o I will not fly when impaired physically in any way
o Etc
>From the Maintenance and Airworthiness side of the equation:
* Identify maintenance areas to pay closer attention to
o Re-torque gear legs at oil changes
o Engine baffling
o Tailwheel spring attach bracket
o Control linkages, rod-ends and use of washers
o Engine mounts
o Empennage and spar attach points
* Realize the additional strain placed on aircraft used regularly for
aerobatics and increase inspection requirements
* Have an experienced and concerned independent person look over your
aircraft
o the builder may have a prejudiced eye when it comes to inspecting and
maintaining their own aircraft
o a non-builder may not have the experience or know how to maintain
their own aircraft
o It may be hard on the pride, but having a critical but considerate
individual inspect our airplanes may help point out deficiencies. In any
case, it helps start an exchange of information.
o Put together a for fun fly-in competition where we all look at each
others planes to see who can find the most items that could be improved?
Conclusion: It was worthwhile time spent with other Rocketeers. The
session was well received and most came away feeling positive and better
informed. Many expressed an interest in continuing with similar 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 to maximize the
thrill of flying this great aircraft safely, and be able to encourage others
to do the same would be a great goal!

Well done Jeff. Wish I could have been there.
