FAA Ground School Practice Test

What is the maximum time frame an approved chair-type parachute may be packed by a rigger prior to being carried in an aircraft for emergency use?

1. 120 days

2. 180 days

3. 240 days

4. 360 days

The correct answer is: 180 days

An approved chair-type parachute must be packed by a certified rigger within a maximum time frame of 180 days before it is carried in an aircraft for emergency use. This regulation is in place to ensure that the parachute is in optimal condition and that all components function correctly when needed. If a parachute is packed beyond this time frame, it may lead to increased risk during an emergency situation due to potential degradation of the materials or lack of proper serviceability checks. The 180-day requirement balances the need for readiness with the realities of material science; parachute fabrics and components can wear over time, even in storage. Regular maintenance and repacking within this period help to mitigate risks and ensure safety for the occupants of the aircraft.
