DG Aviation GmbH (Type Certificate Previously Held by DG Flugzeugbau GmbH) Gliders
This AD applies to DG Aviation GmbH (type certificate previously held by DG Flugzeugbau GmbH) Model DG-1000T gliders, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all DG Aviation GmbH (type certificate previously held by DG Flugzeugbau GmbH) Model DG-1000T gliders. This AD was prompted by reports of propeller separation. This AD requires revising the glider flight manual and installing "Motor INOP" placards to prohibit operation with the powerplant. The FAA is issuing this AD to address the unsafe condition on these products.
Within 3 days after the effective date of this AD, comply with either paragraph (g)(1) or (2) of this AD.
(1) Revise the flight manual for your glider and install “Motor INOP” placards in accordance with paragraphs 1 and 3 of the Instructions in DG aviation GmbH Service Information No. 116-25, Issue 01.b, dated May 12, 2025. The owner/operator (pilot) holding at least a private pilot certificate may revise the existing flight manual and must enter compliance with the applicable paragraph of this AD into the glider maintenance records in accordance with 14 CFR 43.9(a) and 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.
