1.1 Record of Revisions
All revisions of this manual must be recorded in chapter 1.2. Revisions of chapter
“6 OPERATING DATA / LIMITATIONS” requires approval by EASA.
All incorporated Temporary Revisions must be recorded in chapter 1.4.
The new or amended text is indicated by a vertical line at the left hand side of the revised
page, with the revision number and data appearing at the bottom of the page.
If pages are revised which contain information valid for your particular serial number
(modification level of the engine, Equipment Inventory, etc.), then this information must be
transferred to the new pages in hand–writing.
Temporary revisions, if applicable, are inserted behind the cover page of this manual.
Temporary revisions are used to provide information on systems or equipment until the next
‘permanent’ revision of the Engine Manual. When a ‘permanent’ revision covers a Mandatory
or Optional Design Change (MDC or ODC), then the corresponding temporary revision is
superseded.
It is the responsibility of the operator to ensure that this manual is maintained to a current
status.
If the address or the ownership of the engine/aircraft changes, an address card has to be sent
to Austro Engine GmbH.
