Plain English Summary

2/10 complexity

What this does: Requires operators of Cessna 172 RG aircraft (S/N 172 RG 0001–0769) to install, before further flight, a cockpit placard (letters ≥2.4 mm) warning that elevator movement may be limited when right rudder is applied; remove the placard after complying with AD/CESSNA 170/45.

Why it matters: The instruction addresses an identified jack‑screw/bungee failure that can reduce elevator control; pilots are told to centre the rudder and land as soon as practicable. Costs and actions fall on aircraft owners/operators for immediate compliance and on pilots for altered in‑flight responses.

AD/CESSNA 170/44 Limited Elevator Movement - Placard 9/81

Applicability: All model 172 RG with S/Nos 172 RG 0001 to 172 RG 0769.

Requirement: 1. Install a locally manufactured placard in clear view of the pilot, using letters at least 2.4 mm (3/32 inch) high, which reads:

“ELEVATOR MOVEMENT MAY BE LIMITED WHEN RIGHT RUDDER IS APPLIED IF THIS CONDITION IS ENCOUNTERED, CENTER THE RUDDER PEDALS, LAND AS SOON AS PRACTICAL AND COMPLY WITH AD/CESSNA 170/45 PRIOR TO FURTHER FLIGHT.”

Remove placard after compliance with AD/CESSNA 170/45.

Note: FAA AD 81-14-06 Amdt 39-4158 and Cessna Single Engine Service Letter SE80-99 Rev 1 refer to this subject.

Compliance: Before further flight.

Background: In-service failure of the jack screw shaft of the rudder trim/nose gear steering bungee could limit elevator control system movement and for safety, the aircraft should land as soon as practicable after the pilot experiences elevator control limited movement.
