 From the Honeywell Website:

After production and distribution of the Cycle 1001 databases (effective date 14-Jan-2010),Honeywell was informed by our data supplier, Jeppesen, that the data file delivered to Honeywell contained incorrect Dynamic Magnetic Variations for all terminal and en route waypoint records.For that reason, it is imperative that the incorrect databases NOT be used for arrival, departure, or approach operations.

Any of the following databases contain incorrect data that must be corrected before use:
1. Cycle 1001 databases downloaded from Wingman Services prior to January 12th, 2010.
2. Cycle 1001 databases on programmed media and received prior to January 12th, 2010.

To fix this issue, a corrected database must be installed prior to the next flight. For all units except the KLN 94, refer to the applicable pilot’s guide for database update instructions. For operators using KLN 94 equipment who downloaded the Cycle 1001 database prior to 16 January 2010, please refer to Service Information Letter "Incorrect Dynamic Magnetic Variation Data on database cycle 1001" PN D201001000010.

To obtain a corrected database:

1. For customers with web distribution, download the new data file Cycle 1001 and load the new database in the unit.

2. For customers with all other types of distribution, return the distribution media (except diskettes) to Wingman Services and a new Cycle 1001 will be sent back to be loaded into the unit.

Note that if it cannot be determined whether the Cycle 1001 database falls within the categories listed above, or if there is any uncertainty about the correctness of the data, a corrected database should be installed.
