ED Decision 2007/015/R
(See AMC E 80)
(a) Equipment Drives and Mountings
(1) Mountings and drives for all equipment installed on the Engine must be designed:
(i) To permit safe operation of the Engine with the equipment fitted, and
(ii) So that Failure of equipment will not result in further damage likely to produce a Hazardous Engine Effect.
(2) Mountings and drives for equipment identified under CS-E 20(c) must be designed and located so as to minimise the possibility of defective equipment necessitating Engine shut-down as a result of:
(i) Contamination or major loss of the Engine oil supply, or
(ii) Engine malfunctioning through the application of excessive torque, loose parts falling into the Engine, flailing of the drives, etc.
(b) The equipment identified under CS-E 20(a) must be approved as an integral part of the Engine and must meet the relevant specifications of CS-E. Unless the specifications prescribed in subpart C or E, as appropriate, will subject this equipment to such cycles of operation as to adequately represent all the critical conditions affecting its airworthiness to which it may be expected to be exposed during service, the equipment specification must state those additional airworthiness specifications for which evidence of compliance will be needed.
(c) The equipment identified under CS-E 20(c) will be accepted for use on an Engine subject to:
(1) The equipment meeting the interface specifications identified under CS-E 20(d);
(2) Evidence of satisfactory compliance with CS-E 80(a);
(3) Being approved under the relevant aircraft Type Certificate.
(d) Equipment with high-energy rotors must be such as to meet one of the following:
(1) Failures will not result in significant non containment of high energy debris, or
(2) An acceptable level of integrity of the design, including the high energy parts, has been established, or
(3) An appropriate combination of (1) and (2).
[Amdt. No.: E/1]
EASA engine safety regulations mandate secure equipment mountings preventing failures causing hazardous effects or engine shutdowns. Critical equipment requires integral engine approval, meeting airworthiness standards. High-energy rotor failures must minimize debris or demonstrate design integrity. Equipment must meet interface specifications and aircraft type certificate requirements for safe engine operation.
