Airworthiness Directive · Amendment 39-18469 · Elevator tab control system
Textron Aviation, Inc. Airplanes
Superseded. A later AD replaced this one: AD 2016-17-08. Comply with the one in force.
This AD applies to Textron Aviation, Inc. Models 310 through 310R, E310H, E310J, T310P through T310R, 310J-1, 320 through 320F, 320-1, 335, 340, 340A, 401 through 401B, 402 through 402C, 411, 411A, 414, 414A, and 421 through 421C airplanes (type certificates 3A10, 3A25, and A7CE previously held by Cessna Aircraft Company), all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for all Textron Aviation, Inc. Models 310 through 310R, E310H, E310J, T310P through T310R, 310J-1, 320 through 320F, 320-1, 335, 340, 340A, 401 through 401B, 402 through 402C, 411, 411A, 414, 414A, and 421 through 421C airplanes (type certificates 3A10, 3A25, and A7CE previously held by Cessna Aircraft Company). This AD requires replacement and repetitive inspections of the hardware securing the elevator trim push-pull rod. This AD was prompted by lessons learned in accident investigation support, analysis of past accidents, and NTSB determinations of probable cause. That information indicates that following the loss of the attachment hardware connecting the elevator trim tab actuator to the elevator trim tab push-pull rod, the elevator tab may jam in a position outside the normal limits of travel. We are issuing this AD to correct the unsafe condition on these products.
Unless already done, do the actions in paragraphs (f)(1) through (f)(3) of this AD within the compliance times specified.
(1) Within the next 90 days after April 26, 2016 (the effective date of this AD), replace the elevator trim push-pull rod attachment hardware on the elevator trim actuator and the trim tab ends of the push-pull rod following steps 2 through 5 of the accomplishment instructions in Textron Aviation, Inc. (Cessna) Multi-engine Service Bulletin No. MEB-27-02, dated February 29, 2016.
(2) Following the replacement required in paragraph (f)(1) of this AD, at intervals not to exceed 100 hours TIS or 12 months, whichever occurs first, repetitively inspect the elevator trim push-pull rod attachment hardware on the elevator trim actuator and the trim tab ends of the push-pull rod, and replace the hardware if necessary before further flight following the Compliance NOTE on page 1 of Textron Aviation, Inc. (Cessna) Multi-engine Service Bulletin No. MEB-27-02, dated February 29, 2016.
(3) After April 26, 2016 (the effective date of this AD), any time the elevator trim push-pull rod attachment hardware on the elevator trim actuator and/or trim tab ends of the push-pull rod is removed for any reason, discard the old hardware (bolt, nut, washer and cotter pin) and replace with new hardware following steps 3 and/or step 5 of Textron Aviation, Inc. (Cessna) Multi-engine Service Bulletin No. MEB-27-02, dated February 29, 2016.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
