Connecting ring pairs are vital for the safe connection and reliable separation of tow cable and tow release.
The type certification stipulates that every Tost tow release must be operated only with a ring pair meeting the aeronatical standard LN 65091 (in its respective current edition).
These connecting ring pairs must be stamped with the manufacturer’s name and the standard number.
Welded rings are categorically prohibited.
Their use voids the warranty of our releases. Welded rings cause damages to the releases. Moreover, undersized or deformed rings can cause the ring pair to jam the release and inhibit correct operation under load, a potential danger for the pilot.
Connecting ring pairs must be visually checked and measured at regular intervals. Ring pairs that deviate from the standard dimensions must be replaced.
Feel free to ask for the permissible measurements.
