A. General

(1) Operation and Maintenance Manual

(a) The engine model designation used throughout this manual (RR300 Series) refers to the same

engine model (250-C300/A1) that is both stamped on the engine data plate and listed on the

official Engine Type Certificate, Number E4CE, issued by the FAA. The RR300 Series

Operation and Maintenance Manual (OMM) is part of a set of manuals that helps the operator

do the necessary maintenance to the engine. It is written so a technician who does not know

the engine can:

- Do the maintenance and the servicing of the engine systems and components

- Isolate failures of the engine systems and components.

- Use the OMM when the engine is installed on the aircraft.

(b) Rolls-Royce technical publications, in whole or in part, cannot be utilized as a means to

establish serviceability of material not manufactured or approved by Rolls-Royce. Rolls-Royce

technical publications and documents are developed solely for use in support of applicable

Rolls-Royce parts. Parts, materials, or processes not approved by Rolls-Royce were not

considered in the development of Rolls-Royce technical publications due to Rolls-Royce not

having knowledge of any specifications or design criteria for parts, overhaul or repair processes

of parts or material not authorized by Rolls-Royce. Therefore, Rolls-Royce technical

publications must not be used to support or maintain engines, modules, or parts using details,

parts, materials, or processes that are not Rolls-Royce approved. Rolls-Royce disclaims any

liability for the performance or the failure to perform of engines, modules or parts that have

been maintained or supported using parts, materials, or processes not authorized by

Rolls-Royce.

J. Revisions and Service Bulletins

(1) Issue of Revisions.

(a) The manufacturer regularly issues revisions to the maintenance manual to keep it at the correct

standard. The revisions add, remove, and/or change data as necessary. All revisions are by

replacement of pages. You must not use hand-written revisions.

(b) A letter of Transmittal is sent with each revision. The transmittal letter:

- Is the authority to put the revision into the manual

- Gives instructions on how to put the revision into the manual.

(c) You are recommended to keep the transmittal letters at the front of the manual for reference.

(d) Each revision has a specified number and date. Revisions start at No. 1 and continue in

sequence.

(e) A Record of Revisions page is located at the front of the manual. When you put a revision into

the manual, you must write the revision number and its issue date on the Record of Revisions

page.

(f) A vertical block line or an upper case "R" at the left side of a page shows that the data adjacent

to the line has changed. If a black line is aligned with the page number and date, this means

that the data has not changed, but some of the data on the page has moved to or from a

different page.

(2) Temporary Revisions.

(a) When it is necessary to include data in the manual quickly, a Temporary Revision (TR) is

issued. The first page of the TR gives the transmittal instructions. The data/instructions in a TR

replace the equivalent data/instructions in the manual. A TR can also be used to include data

before the subsequent revision.

(b) Each TR is printed on yellow paper. The TR numbers are in sequence and start at - 1 in each

chapter. The chapter number goes in front of the TR number to give each TR an identification

code. For example 72-1, 72-2, 72-3, and so on, 79-1, 79-2, 79-3, and so on.

(c) The data/instructions in a TR are included in a revision (usually, the subsequent revision to the

manual) or a subsequent TR replaces it. When a revision includes the data/instructions of a

TR, the transmittal letter includes an instruction to remove the applicable TR. When a

subsequent TR replaces a TR, the subsequent TR includes an instruction to remove the

applicable TR. You must not remove a TR from the manual unless you get an instruction to do

so in the Transmittal Letter of a revision or on the first page of a subsequent TR.
