CS-E 1030 Time Limited Dispatch
(See AMC E 1030)
(a)If approval is sought for dispatch with Faults present in an Electronic Engine Control System (EECS), a time limited dispatch (TLD) analysis of the EECS must be carried out to determine the dispatch and maintenance intervals.
(b)For each dispatchable configuration it must be shown by test or analysis that:
(1)The Engine remains capable of meeting all CS-E specifications for:
(i)The operability aspects covered by CS-E 500(a), CS-E 750 and CS-E 745;
(ii)Re-light in flight covered by CS-E 910.
(2)The ability to control the Engine within limits is maintained;
(3)Protection is maintained against Hazardous Engine Effects, if provided solely by the EECS and shown to be necessary by the safety analyses required under CS-E 510 and CS-E 50;
(4)A means is maintained to provide necessary signals to identify EECS Faults;
(5)A further single Failure in the EECS will not produce a Hazardous Engine Effect;
(6)The Engine continues to meet its certification specifications for external threats;
(7)The proposed dispatch interval is justified.
(c)The time-weighted-average of the Full-up Configuration and all allowable dispatch configurations with Faults, must meet the Loss of Thrust Control / Loss of Power Control (LOTC/LOPC) rate for the intended application(s).
(d)The periods of time allowed prior to rectification of Faults must be documented in the appropriate manual(s).
(e)Provision must be made for any no-dispatch configuration to be indicated to the flight crew.
