soa...@yahoo.com
Supplemental notice of proposed rulemaking (SNPRM).
The FAA is revising a notice of proposed rulemaking (NPRM) that would have applied to certain Schempp-Hirth Flugzeugbau GmbH (Schempp-Hirth) Model CIRRUS gliders. This action revises the NPRM by changing references to the affected glider model from CIRRUS to STANDARD CIRRUS throughout the proposed airworthiness directive (AD). The FAA is proposing this AD to address the unsafe condition on these products. The FAA is requesting comments on this SNPRM.
The FAA must receive comments on this SNPRM by January 12, 2026.

The commenter noted that the CIRRUS sailplane is a different type of glider model than the STANDARD CIRRUS sailplane with a different type of elevator.The FAA agrees with the commenter's request and has revised this proposed AD as requested.
