All Jetstream Series 3200 aircraft up to and including constructors number 956.

Requirement: Action in accordance with British Aerospace Mandatory Service Bulletins 27-A-JA 881041 Revision 2 and 27-JM 5313 Revision 2, or 27-JM 5322.

This amendment is effective from 9 December 1993.

Background: A failure of the flap torque shaft universal joint securing rivet occurred.

This condition could have resulted in asymmetric flap deployment. Amendment 1 introduced an alternative modification (JM 5322) to suit a different joint configuration, and required inspection of joints that had already been modified.

Amendment 3 upgraded 27-JM5313 to Rev 2 which revised a periodicity. Amendment 4 included the 3200 series.

Amendment 5 is issued to introduce optional terminating action for this directive.
