Summary
This document proposes to supersede Airworthiness Directive (AD) 96-19-07, which currently requires the following on Burkhart Grob Luft-und Raumfahrt (Grob) Models G115C, G115C2, G115D, and G115D2 airplanes: installing a placard that restricts the never exceed speed (Vne) of the affected airplane models from 184 knots to 160 knots; installing on the airspeed indicator glass a red line at 296 km/h (160 knots); installing a placard that prohibits aerobatic maneuvers; and placing a copy of the AD in the Limitations Section of the airplane flight manual. The proposed AD would temporarily retain the flight restrictions that are currently required by AD 96-19-07; and would eventually require accomplishing certain inspections and modifications, as terminating action for these flight restrictions. The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by the proposed AD are intended to prevent loss of control of the airplane caused by excessive speed or aerobatic maneuvers.
