of identification, of EDTO specific procedures or tasks that must be accomplished or verified by EDTO qualified maintenance personnel;

(E) a procedure to verify the status of the aeroplane and that EDTO significant systems and equipment are serviceable for an intended flight;

(c) detailed procedures to prevent multiple identical system maintenance actions and the procedures to be followed if any such maintenance actions cannot be avoided;

(d) a parts control program that ensures:

 (i) the type certification standard is maintained; and

 (ii) the proper identification of parts to maintain the EDTO configuration;

(e) an EDTO reliability program acceptable to CASA that is designed for the early identification and prevention of EDTO-related problems and that contains a reporting procedure for any significant events detrimental to EDTO;

Note   A manufacturer's support program may be an integral part of the reliability program.

(f) a supplement to the air operator's maintenance control manual for use by all personnel involved in EDTO that:

 (i) lists all EDTO supporting programs; and

 (ii) references all the EDTO systems of maintenance; and

 (iii) specifies the maintenance procedures, duties and responsibilities of all relevant maintenance personnel; and

 (iv) indicates where more detailed information on each of these matters may be found in the operator's document system.

Note   The supplement need not be exhaustive provided it complies with subparagraph (iv).

       (3) The AOC holder must ensure that each of the following events is reported to CASA within 72 hours of the event occurring:

(a) IFSD;

(b) diversion or turnback;

(c) uncommanded power change or surge;

(d) inability to control a propulsion engine or to obtain desired power;

(e) malfunction of an EDTO significant system;

(f) any other event detrimental to EDTO.

       (4) The AOC holder must conduct an investigation into the cause of any event mentioned in subclause (3).

       (5) The AOC holder must establish an engine condition monitoring program designed to detect engine deterioration at an early stage and allow for corrective action before safe operation is affected.

       (6) The engine condition monitoring program mentioned in subclause (5) must describe:

(a) the parameters to be monitored, the methods of data collection and analysis, and the corrective action process; and

(b) the procedures to ensure that engine limit margins are maintained so that a prolonged engine inoperative diversion may be conducted without exceeding approved engine limits at all approved power levels and expected environmental conditions.

       (7) The AOC holder must establish an engine oil consumption monitoring program that ensures:

(a) that sufficient oil is carried and available for each engine and APU (if an APU is required for EDTO) to allow completion of a scheduled EDTO flight; and

(b) the oil consumption of an engine or APU (if an APU
