REGULATORY TEXT:  
71-24-09 BEECH: Amendment 39-1347. Applies to Model 56TC (Serial Numbers TG-1 thru TG-76) Airplanes.

Compliance: Required as indicated, unless already accomplished.

To provide information reflecting applicable operating limitations and margin between maximum structural cruising speed and never exceed speed, within the next 50 hours' time in service after the effective date of this AD, revise placards and change airspeed indicator marking as follows:

1) Install placard at lefthand cabin side, adjacent to ignition switch panel reading: "This airplane must be operated as a Normal Category airplane in compliance with the operating limitations stated in the form of placards, markings and manuals (Pilot's Check List). Occupied seats must be in upright position during takeoff and landing. Maximum weight 5990 lb. No acrobatic maneuvers including spins approved.

Max. speed w/landing gear extended (normal) (TG-1 thru TG-71) - 165 m.p.h. (143 knots)

(TG-72 and up) - 175 m.p.h. (152 knots)

Max. speed with flaps extended (15 degrees down) - 175 m.p.h. (152 knots)

Max. speed with flaps extended (normal) - 144 m.p.h. (125 knots)

Max. design maneuver speed - 183 m.p.h. (159 knots)

Minimum control speed single engine - 97 m.p.h. (84 knots)

Max. structural cruising speed (S.L. to 20,000 ft. alt.) - 233 m.p.h. (202 knots)

Max. structural cruising speed (25,000 ft. alt.) - 222 m.p.h. (193 knots)

Max. structural cruising speed (30,000 ft. alt.) - 214 m.p.h. (186 knots)

Never exceed speed (S.L. to 20,000 ft. alt.) - 262 m.p.h. (227 knots)

Never exceed speed (25,000 ft. alt.) - 249 m.p.h. (216 knots)

Never exceed speed (30,000 ft. alt.) - 240 m.p.h. (208 knots)

2) Install placard on floating instrument panel near airspeed indicator reading: "See limitations placard for 'max. structural cruise' and 'never exceed limits'."

3) Re-mark airspeed indicator to extend yellow arc from 240 m.p.h. to 233 m.p.h. so that green arc does not enter this range.

Beechcraft Service Instruction No. 0173-016 considers this subject.

This amendment becomes effective November 30, 1971.
