Centrair 101/201

Airworthiness Directives; Centrair Gliders

We are adopting a new airworthiness directive (AD) for Centrair Model 101, 101A, 101AP, and 101P gliders. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as structural damage to the fuselage. We are issuing this AD to require actions to address the unsafe condition on these products.

Airworthiness Directives; CENTRAIR Models 101, 101A, 101P, and 101AP Gliders

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Airworthiness Directives; CENTRAIR 101 Series Gliders

The FAA adopts a new airworthiness directive (AD) for all CENTRAIR 101 series gliders. This AD requires you to make pen and ink changes to the Limitations Section of the glider maintenance manual to eliminate contradictory information concerning the structural life limit. This AD results from a review by FAA of the Limitations Section of the CENTRAIR Model 101AP glider maintenance manual that revealed conflicting information concerning the structural life limit. We are issuing this AD to assure that the published life limit is adhered to and to prevent structural failure of the glider once this life limit is reached.

Airworthiness Directives; CENTRAIR 101 Series Gliders

The FAA adopts a new airworthiness directive (AD) for certain CENTRAIR 101 series gliders. This AD requires you to replace non- strengthened rudder pedals with reinforced rudder pedals. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. We are issuing this AD to replace the non-strengthened rudder pedals and to prevent failure of the rudder controls. This failure could lead to loss of directional control of the glider.

Airworthiness Directives; CENTRAIR 101 Series Gliders

The FAA adopts a new airworthiness directive (AD) for all CENTRAIR 101 series gliders with other than elevator or aileron part number (P/N) SY991A hinge pins installed. This AD requires you to replace any installed elevator or aileron hinge pins that are not P/N SY991A hinge pins with P/N SY991A pins. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. We are issuing this AD to replace incorrectly heat-treated elevator or aileron hinge pins, which could result in failure of the elevator or ailerons. Such failure during takeoff, landing, or flight operations could lead to loss of glider control.

Airworthiness Directives; S.N. CENTRAIR Model 201B Gliders

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.

Airworthiness Directives; S.N. CENTRAIR 101 Series Gliders

This amendment adopts a new airworthiness directive (AD) that applies to certain S.N. CENTRAIR 101 series gliders. This AD requires you to inspect the airbrake control system for cracks; and if cracks are detected, replace the airbrake control 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 detect cracks in the airbrake control system and replace cracked parts with parts of improved design. A crack in the airbrake control system could prevent the pilot from using the airbrake system.

Airworthiness Directives; S.N. CENTRAIR 101 Series Gliders

This amendment adopts a new airworthiness directive (AD) that applies to all S.N. CENTRAIR (CENTRAIR) 101 series gliders that have modification 101-24 (major cockpit configuration equipped on all gliders manufactured since 1990) incorporated, and do not have modification 101-21 (minor modifications to this cockpit configuration) incorporated. This AD requires installing an attachment lug to the supporting bracket in order to secure the battery discharge warning device. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by this AD are intended to prevent elevator flight control interference caused by an unsecured battery discharge warning device, which could result in reduced or loss of glider control.

Airworthiness Directives; S.N. Centrair 101 Series Sailplanes

This amendment adopts a new airworthiness directive (AD) that applies to all S.N. Centrair (Centrair) 101 series sailplanes. This AD requires replacing the airbrake control system with one of improved design. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by this AD are intended to prevent loss of the airbrake control system caused by cracks in the original design airbrake control system, which could result in an inadvertent forced landing with consequent sailplane damage and/or passenger injury.

Airworthiness Directives; S.N. CentrAir Model 201 (All Types) Sailplanes

This amendment adopts a new airworthiness directive (AD) that applies to S.N. CentrAir Model 201 (all types) sailplanes. This action requires replacing all aileron balancing mass screws made of brass with screws made of steel, inspecting all steel screws for tightness, replacing any loose screws, and applying a normal screw thread safety bond. Incorrect fastening of the aileron balancing mass found on a Model 201 sailplane in France prompted this action. The actions specified in this AD are intended to prevent aileron failure and flutter caused by incorrect fastening of the aileron mass balance, which, if not detected and corrected, could result in loss of control of the sailplane.
