After-market Tandem Risers

USPA Staff

PIA released Service Bulletin PSB-10092020 affecting after-market tandem main risers constructed with obsolete RW2 rings. All sport tandem main risers produced with RW2 rings, or equivalent sized rings, are affected regardless of the hardware manufacturer, the date of manufacture, the material type or the forging process used. This PSB does not affect "solo" main risers that use RW2 rings.

Recent reports of bent rings on tandem main risers are of great concern. At least one after-market manufacturer of obsolete and unapproved tandem risers is using RW2 rings or similar rings, which were discontinued for tandem use in 1996 due to bent ring issues. These rings pass a proof load of 500 lbs. and begin to distort at 2500 lbs. Compliance is MANDATORY – REPLACE BEFORE THE NEXT JUMP.
