69-24-01 AER PEGASO C.A.R.M.A.M.: Amdt. 39-877. Applies to Aer-Pegaso Model M.100S and C.A.R.M.A.M. Model M.200 gliders.
Compliance is required within the next 25 hours' time in service after the effective date of this AD, unless already accomplished.
To detect improper installation of the horizontal stabilizer to the glider, accomplish the following:
(a) Install an inspection window on the left side of the dorsal fin to allow visual confirmation of the elevator "quick disconnect" attachment and paint the two plates of the elevator control transmission fork in accordance with Aer-Pegaso Technical Bulletin N.10/M- 100S, dated September 26, 1969, or an FAA-approved equivalent.
(b) Install the following placard in the cockpit in clear view of the pilot:
"Before the first flight after rigging the tailplane to the fuselage, look through the inspection window located on the left side of the dorsal fin and visually confirm that the end (ball bearing) of the elevator control lever is correctly engaged in the corresponding fork of the elevator control transmission. To do this, it may be necessary to move the control stick in the longitudinal direction in order to bring the lever end into view through the window. If the rigging is correct, the ball bearing will appear between the fork sides."
This amendment becomes effective November 23, 1969.
