CB0286 to simulate the aircraft on the ground with weight-on-wheels. Wait for at least 15 seconds, then move both power levers back toward the propeller reverse position with the flight idle gate triggers in the normal flight position. Verify that the power lever for each engine cannot be moved below the flight idle position.

(f)      Raise the flight idle gate triggers and verify the power levers can be moved below the flight idle position.

(g)     Failure to satisfy the requirements of either test (c), test (f) indicates a failure of the SFISS, which must be rectified before further flight.

               Failure to satisfy the requirements of test (e) indicates a failure of the primary flight idle stop system, which must be rectified before further flight.

               If required application can be made under CAR (1998) Part 21.197 for a special flight permit to ferry an aircraft to a place where rectification of the discrepant flight idle stop system can be accomplished.

           Note 3: The tests prescribed in Requirement 3 essentially reflect the requirements of Brazilian CTA Telegraphic AD T92-08-04 and FAA Emergency AD T92-16-51.

             4.    Incorporate the requirements of Embraer Operations Bulletin OP120-004/99 into the flight crew-training program.

           Note 4: Incorporation of Embraer SB 120-76-0018, Revision 1 (or later revision) constitutes terminating action for Requirements 1 through 4.

           For aircraft incorporating Embraer SB 120-76-0018 (Original Issue)

             5.    Incorporate the SFISS reliability improvements in accordance with Embraer SB 120-76-0022, Original Issue, Revision 1 or Revision 2.

             Upon compliance with Requirement 5, the SFISS configuration may be considered to be equivalent to that specified in Embraer Service Bulletin 120-76-0018, Revision 1, and no further action with respect to this Airworthiness Directive is required.

           Note 5: For Requirement 5, CTA AD 90-07-04 R4, COMPLIANCE (c) also refers

 Compliance: Requirements 1 & 2:

              Prior to the first flight of each day.

           Requirement 3:

             (a)     At each Line Check but not to exceed 100 hours time in service since the last functional test of the SFISS;

             (b)     Immediately following any maintenance where the aircraft is jacked; and

             (c)     Prior to further flight, if circuit breakers CB0582 and CB0583 are required to be reset as a result of Requirement 1 or 2 inspections.

           Requirement 4:

             Unless previously accomplished, no later than 6 months after the effective date of this Directive.

           Requirement 5:

             Unless previously accomplished, no later than 6 months after the effective date of this Directive.

           This Airworthiness Directive becomes effective on 6 September 2001.

           Background:  The manufacturer received reports of propeller overspeed events simultaneously affecting both engines when the power levers were inadvertently moved into the Beta range in flight. Investigation revealed that both circuit breakers of
