Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120 Series Airplanes
All Model EMB-120 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all EMBRAER Model EMB-120 series airplanes, that requires revising the Airplane Flight Manual to ensure that the propeller synchronizer switch is "OFF" after engine start and before takeoff and landing. This action is necessary to prevent a possible loss of airplane control and subsequent injury to the flight crew and passengers. This action is intended to address the identified unsafe condition.
To prevent a possible loss of airplane control and subsequent injury to the flight crew and passengers, accomplish the following:
(a) Within 30 days from the effective date of this AD, do the actions specified in paragraphs (a)(1) and (a)(2) of this AD.
(1) Revise the Limitations Section of the AFM to include the following text in “Section II—Limitations” under title “Powerplant,” subtitle “Propeller” (this may be accomplished by inserting a copy of this AD into the AFM):
“For takeoff and landing PROP SYNC must be OFF”
Note 1: When a statement identical to that in paragraph (a)(1) of this AD has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed from the AFM.
(2) Revise the Normal Procedures section of the AFM by inserting pages 4-17, 4-23, and 4-27 of EMBRAER AFM 120/794, Revision 65, dated June 10, 2003, into the AFM.
