Airworthiness Directive · Amendment 39-14720 · DG Flugzeugbau GmbH Model DG-1000S Sailplanes
DG Flugzeugbau GmbH Model DG-1000S Sailplanes
This AD affects all Model DG-1000S sailplanes, all serial numbers, that are certificated in any category.
We are adopting a new airworthiness directive (AD) for all DG Flugzeugbau GmbH Model DG-1000S sailplanes. This AD requires you to modify the elevator control at the stabilizer assembly, replace a placard on the fin, and incorporate changes in the FAA-approved sailplane flight manual (SFM). This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent the rigging of the horizontal stabilizer without properly connecting the elevator, which, if not prevented, could lead to an inoperative elevator. An inoperative elevator could lead to loss of control of the sailplane.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Modify the elevator control at the stabilizer assembly as follows: (i) Replace the rod-end, part number (P/N) 5St94 (or FAA-approved equivalent P/N), with a rod-end 5St94 modified to P/N 10St97/1 (or an FAA-approved equivalent P/N); (ii) Install deflector part number 10St97/2 (or an FAA-approved equivalent P/N); and (iii) Replace the placard on the fin. | Within the next 25 hours time-in-service (TIS) after September 18, 2006 (the effective date of this AD) | Follow DG Flugzeugbau GmbH Technical Note No. 413/3, dated April 28, 2004. |
| (2) The parts that this AD requires to be replaced as well as those to be installed could have replacement parts approved under 14 CFR 21.303. Any such parts approved per this regulation and installed are subject to the actions of this AD. In addition, nothing in this AD prevents the installation of such alternatively approved parts provided they meet current airworthiness standards including those actions cited in this AD | Not Applicable | Not Applicable. |
| (3) Incorporate changes in the FAA-approved sailplane flight manual, as specified in paragraph 6a) of the Instructions section of DG Flugzeugbau GmbH Technical Note No. 413/3, dated April 28, 2004 | Within the next 25 hours TIS after the effective date of this AD | The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may do the flight manual change requirement of this AD. Make an entry in the aircraft records showing compliance with this portion of the AD following section 43.9 of the Federal Aviation Regulations (14 CFR 43.9). |
| (4) Do not install any rod end P/N 5St94 (or FAA-approved equivalent P/N) unless it is modified to DG Flugzeugbau GmbH rod-end P/N 10St97/1 (or FAA-approved equivalent P/N) | As of September 18, 2006 (the effective date of this AD) | Not Applicable. |
