A Federal Aviation Administration Senior Rigger found excess wear on the top and bottom of this reserve parachute closing loop during an inspection. Even though you cannot see the entire loop without opening the reserve, you can check the condition of the top of the loop during a normal pin check. Any fuzz or broken strands are an indicator that the reserve loop is in need of replacement. Reserve loops can wear over time, so your reserve loop may be ready for a replacement before the reserve is due for the next inspection and repack. Check the condition of both your main and reserve closing loops frequently, and replace any worn loop immediately. If you have a question about the condition of your closing loops, ask a parachute rigger for assistance.
