Checklist für Diamond DA40 NG

Edition #: 17.3 Edition date: 15.04.2017

Please observe:

The file you are receiving hereby combines all three sections of the checklist: Normal
Checklist, Emergency Checklist and Abnormal Checklist.

All pages of a new edition will have the same new “edition #” and “edition date”, even if
only one page was amended and all other pages still have the same, unchanged content.

Therefore the “List of Effective Pages” (LEP) is provided. It is here where you can see
whether a particular page was amended. Pages which have been amended by a new
edition will be marked yellow. For all other pages you will see which original “edition #”
(and of course any higher “edition #”) is still valid.

Note:
The system of assigning “Edition #” is as follows:
• if the revision affects all types, a new edition # (without a decimal figure) will be
assigned to all of the checklists
• if the revision does not affect all types, the affected checklists will get subsequent
“decimal figures” until a major revision affecting all checklists is issued.

Have a lot of nice flights and happy landings!

NORMAL CHECKLIST

Diamond DA40 NG

This checklist is compiled according the guidelines of GAMA Specification No.1, SECTION 3, para 3.5,
SECTION 3A, para 3A.5 and SECTION 4, para 4.5.
The “Amplified Normal Procedures”, „Amplified Emergency Procedures“ and „Amplified Abnormal
Procedures“ according GAMA Specification No. 1 are in the DA40 Airplane Flight Manual Chapters 4A,
3 and 4B.

This checklist is a Recommended Operator Checklist and for reference only.

It is not a substitute for and does not supersede the current approved Airplane Flight Manual or any
of its supplements or parts thereof, or any training or procedures required by any regulatory or
advisory bodies.
This checklist may not contain all procedures shown in the Airplane Flight Manual. For a
comprehensive listing of all procedures consult the Airplane Flight Manual.
Use of the checklist is at the user's sole risk and discretion.
Any possible liability of Diamond Flight Training and/or Diamond Aircraft Industries for any
damages, injury or death resulting from its use is excluded.
All such terms and conditions shall be deemed to be explicitly accepted in full by using the checklist.
If you do not understand, or if you disagree with, any of the above terms and conditions and in any
jurisdiction that does not give effect to all provisions of these terms and conditions any use of the
checklist is not permitted.

Use of the electronic checklist (if available):

Before using the electronic checklist on the G1000 the following sections have to
be completed using this paper checklist:
• Preflight interior + exterior
• Preflight exterior
• Check before engine start items 1 to 21 (may be completed by heart).

This checklist also serves as a back up for the electronic checklist in case the
G1000 MFD is not available.
