NTSB Safety Recommendations A-12-9 through -12

************************************************************

The National Transportation Safety Board makes the following

recommendations to the National Air Racing Group Unlimited

Division:

Require aircraft owners in the unlimited class to provide an

engineering evaluation that includes flight demonstrations

and analysis within the anticipated flight envelope for

aircraft with any major modification, such as to the

structure or flight controls. (A-12-9)

Develop a system that tracks any discrepancies noted during

prerace technical inspections and verifies that they have

been resolved. (A-12-10)

Provide high g training to pilots, including techniques to

mitigate the potential effects of high g exposure, as part

of preparations before the Reno National Championship Air

Races (NCAR) and during daily briefs at the NCAR. (A-12-11)

Evaluate the feasibility of requiring pilots to wear g suits

when racing at the Reno National Championship Air Races; if

the evaluation determines it is feasible, implement a

requirement. (A-12-12)
