NTSB Safety Recommendations A-11-1 through -6

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

The National Transportation Safety Board makes the following

safety recommendations to the Federal Aviation

Administration:

Require Cessna Aircraft Company and other manufacturers

whose restraint system designs permit an occupant to use an

inactive airbag restraint system not intended for use in his

or her seat to modify their restraint system designs to

eliminate that possibility, and require them to modify

restraint systems in existing airplanes to eliminate the

possibility of misuse. (A-11-1)

Revise the guidance and certification standards concerning

restraint systems to recognize and prevent potential misuse

scenarios, including those documented in this safety study.

(A-11-2)

Modify the special conditions for the installation of

inflatable restraints on general aviation airplanes (at

Federal Register, vol. 73, no. 217 [November 7, 2008], p.

66163) to provide specific guidance to manufacturers as to

how they should demonstrate that the protection is effective

for occupants that range from the 5th percentile female to

the 95th percentile male. (A-11-3)

Require the retrofitting of shoulder harnesses on all

general aviation airplanes that are not currently equipped

with such restraints in accordance with Advisory Circular

(AC) 21-34, issued June 4, 1993. (A-11-4)

Evaluate the potential safety benefits and feasibility of

requiring airbag-equipped aircraft to have the capability to

capture and record, at a minimum, data concerning crash

dynamics and airbag deployment criteria that can be reviewed

after a crash to determine whether the system performed as

designed. (A-11-5)

Develop a system to track individual aircraft information

about aircraft safety equipment, such as restraint systems,

airbags, aircraft parachutes, and other specific aircraft

equipment, designed to improve crash outcomes. (A-11-6)
