Airworthiness Directive · Amendment 39-12029 · S.N. CENTRAIR Model 201B Gliders
S.N. CENTRAIR Model 201B Gliders
This AD affects Model 201B gliders, all serial numbers, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that applies to all S.N. CENTRAIR Model 201B gliders. This AD requires you to modify the rear canopy emergency release system. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified in this AD are intended to prevent the rear canopy retaining strap from not releasing properly during the emergency egress procedure because of the current design of the rear canopy emergency release system. This condition, if not corrected, will not allow the rear canopy to completely separate from the glider and could result in potential injury to the pilot during an emergency egress.
To address this problem, you must accomplish the following:
| Actions | Compliance times | Procedures |
|---|---|---|
| (1) Install a mechanism that automatically releases the rear canopy strap when the emergency canopy lever is actuated | Within the next 3 months after January 27, 2001 (the effective date of AD) | Follow the procedures in S.N Centrair Process Sheet for Fitment of the Release Unit for the Rear Canopy Strap on Glider Centrair 201 “Marianne”, dated March 17, 1999 (or the instructions provided with the modification kit). The document specified above is referenced in S.N. CENTRAIR Service Bulletin No. 201-16, Revision 1, dated December 12, 1999. The inspection referenced in the service bulletin is not required by this AD. |
| (2) Do not install a rear canopy emergency release system without incorporating the modification referenced in paragraph (d)(1) of this AD | As of January 27, 2001 (the effective date of this AD) | Not Applicable. |
