The FAA is revising an existing airworthiness directive (AD), that is applicable to Hartzell Propeller Inc. (formerly TRW Hartzell Propeller) models HC-B3TN-2, HC-B3TN-3, HC-B3TN-5, HC-B4TN-3, HC-B4TN- 5, HC-B4MN-5, and HC-B5MP-3 turbopropellers. That AD requires, before further flight, that all new propellers being installed and all serviceable propellers being reinstalled, are attached using part number (P/N) B-3339 bolts and P/N A-2048-2 washers, and that the bolts are properly torqued. That AD also requires a onetime torque-check of P/N A-2047 bolts that are already installed through propellers and replacement of those bolts if necessary, with P/N B-3339 bolts and P/N A-2048-2 washers. This AD requires the same actions, and includes the use of other equivalent FAA-approved serviceable bolts and washers. This AD results from the need to make nonsubstantive wording changes and additions to clarify that terminating action is achieved by attaching propellers with P/N B-3339 bolts and P/N A-2048-2 washers or other equivalent FAA-approved serviceable bolts and washers, to the engine flange, as instructed in the compliance section of this AD. We are issuing this AD to preclude propeller attaching bolt failures or improperly secured propellers, which could lead to separation of the propeller from the airplane.

Aviointeriors S.p.A. Series 312 Seats
The FAA is superseding an existing airworthiness directive (AD), that is applicable to Aviointeriors S.p.A. (formerly ALVEN), series 312 seats. That AD requires initial and repetitive inspections of the seat central crossmember for cracks, and if necessary, replacing the crossmember with a new crossmember. This ad requires the same actions and adds other crossmember part numbers for inspection. In addition, this AD replaces the original design crossmembers with reinforced design crossmembers as optional terminating actions to the repetitive inspections. This AD results from reports of 88 cracked seat central crossmembers and 60 aisle side crossmembers, to date; and, from the introduction of reinforced optional seat crossmembers by the manufacturer. We are issuing this AD to prevent the loss of the structural integrity of the seat due to cracks in seat crossmembers, which could lead to passenger injury.

Pilatus Aircraft Limited Models B4-PC11, B4-PC11A, and B4-PC11AF Sailplanes
The FAA adopts a new airworthiness directive (AD) for all Pilatus Aircraft Limited (Pilatus) Models B4-PC11, B4-PC11A, and B4- PC11AF sailplanes. This AD requires you to repetitively inspect the control-column support for cracks and, if any cracks are found, replace the control-column support with a new support. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. We are issuing this AD to detect and correct cracks in the control-column support, which could result in failure of the support. This failure could lead to loss of the primary flight control system.

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.

Glaser-Dirks Flugzeugbau GmbH Model DG-800B Sailplanes
The FAA adopts a new airworthiness directive (AD) for all Glaser-Dirks Flugzeugbau GmbH (DG Flugzeugbau) Model DG-800B sailplanes equipped with a SOLO 2625 engine or a Mid-West AE 50T engine. This AD requires you to modify the coolant pump and fuel pump electrical circuits, remove the non-resettable digital engine indicator (DEI) circuit breaker (4-ampere) and replace with a resettable 5-ampere circuit breaker, secure (for sailplanes with a SOLO 2625 engine) the choke butterfly valve axis, install edge protection at the sharp edges of the resettable 5-ampere DEI circuit breaker, and incorporate changes in the FAA-approved sailplane flight manual. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent electrical failure of the fuel and coolant pumps if a non-resettable circuit breaker trips. This could result in power loss with the inability to restart the fuel pump during a critical phase of flight (for example, takeoff under own power).

LET a.s. Model Blanik L-13 AC Sailplanes
The FAA adopts a new airworthiness directive (AD) for all LET a.s. (formerly LET n.p.) (LET) Model Blanik L-13 AC sailplanes. This AD requires you to replace the original control bridge with the new strengthened control column mounting bridge. This AD is the result of a report of one case of cracks in the attachment of control levers on the control bridge. We are issuing this AD to correct cracks in the bedding of the front and rear control levers, which could result in failure of the control bridge for the sailplane. This failure could lead to loss of sailplane control.
