AD 98-04-30

Applies to

Model DG-500M gliders, all serial numbers, certificated in any category.

The FAA's summary

This amendment adopts a new airworthiness directive (AD) that applies to all Glaser-Dirks Flugzeugbau GmbH (DG Flugzeugbau) Model DG- 500M gliders. This AD requires repetitively inspecting the propeller mounting plate for cracks, replacing any cracked propeller mounting plate, and modifying the bolt connections of the propeller mounting plate. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified in this AD are intended to prevent the propeller mounting plate from separating from the glider, which could result in propeller separation and possible loss of control of the glider.
