United Parachute Technologies has recently changed the weight limit capability of the Vector Tandem System and the Sigma Tandem System when used in conjunction with the following (airworthy) canopies, regardless of their date of manufacture.
The previous weight limit was 450 lbs.
The new approved gross weight limit is 500 lbs. This translates to approximately 50 lbs. of gear weight and 450 lbs. of personnel weight.
Please keep this official weight-change authorization (in your office files and in the aircraft with your FAA-Exemption) for future reference because the canopies you currently jump are placarded for 400-450 lbs. This notice supercedes current placarding.
