If you do intentional aerobatics you will need to wear one. I found this at the below url:

"All other U.S. made emergency parachutes, the FAA Parachute Rigger that repacks the parachute is certifying that the parachute is airworthy for the next 180 day cycle. In other words....it is up to the FAA Certificated Parachute Rigger to inspect, test if necessary, and re-certify airworthy your parachute. The parachute may last 8 years or 30 years, it all depends on the care and condition of the parachute. (just like the annual inspection by your A&P mechanic for your aircraft),

I inspect every pilot parachute that comes into my parachute loft, those that don't pass you never see, the ones that make it are advertised here & have gone through my tough inspection and will last many years if taken care of. My name is Don Mayer, Master Parachute Rigger, FAA Designated Parachute Rigger Examiner, 36 years experience, owner of the Parachute Shop. 1-800-872-2488"
