(1) If the rod is manufactured by TAC, no further action is required.

(2) If the rod is manufactured by SARMA, vendor P/N 14132B, prior to further flight, replace the rod with a TAC rod; or a SARMA rod, vendor P/N 14132-C; in accordance with the applicable service bulletin.

(b) As of the effective date of this AD, no SARMA rudder pedal connection rod, P/N 14132B, shall be installed on any airplane.

(c) An alternative method of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Standardization Branch, ANM-113.

(d) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.
