Compliance is required as indicated unless already accomplished.
Part I Airspeed Restriction/Front Strut Replacement
a. Effective immediately, unless already accomplished, attach the following operating limitation placard near the airspeed indicator in full view of the pilot:
"DO NOT EXCEED 153 MPH CAS MAXIMUM OPERATING SPEED"
The letters on this placard must be at least 1/8 inch in height and on suitable material which can be expected to remain affixed in position and resist deterioration. This placard may be installed by the pilot.b. Within three (3) months after the effective date of this airworthiness directive, accomplish either:
1. Remove red radial marking on airspeed indicator at 162 MPH (141 KTS). Remark indicator with red radial line at 153 MPH (133 KTS). Change Operations Limitations Card as follows: Replace Airspeed Limitations "GLIDE or DIVE-----162 MPH CAS" with "MAXIMUM OPERATING SPEED----153 MPH CAS". Bellanca Service Kit 256 may be used to accomplish this. (Bellanca Service Letter C-127 pertains to this subject.) After marking indicator, the placard required per paragraph (a) above may be removed, or
2. Remove wing front lift struts Bellanca P/N 5-144 and install replacement wing front lift struts Bellanca P/N 5-392 (Bellanca Service Letter C-127 and Service Kit 257 pertain to this subject). After the struts are replaced, the placard per paragraph (a) above may be removed and the airspeed markings and Operations Limitations Card per paragraph (b.1) above may be returned to theiroriginal 162 MPH CAS markings.
NOTE: The Bellanca P/N 5-392 strut may be identified by a square tube fitting at the wing end.
Part II Acrobatic Maneuvers Placard/Accelerometer Markings/Operating Limitations Card Change. Applies to All Bellanca (Champion) Acrobatic Models As Indicated. (Bellanca Service Letter C-128 pertains to this subject.)
a. Effective immediately, flight operations shall be conducted in accordance with the limitations specified below.
b. Within three (3) months after the effective date of this airworthiness directive unless already accomplished, replace the acrobatic maneuvers placard and remark the accelerometer if applicable as indicated below.
