Honeywell has released an urgent safety bulletin, noting that updates for some Bendix/King databases contained incorrect information.
The bulletin concerns databases for KLN 35A, KLN 88, KLN 89, KLN 89B, KLN 90, KLN 90A, KLN90B, KLN 94, KLX 100, KLX 135, KLX 135A, and KLN 900.
According to officials with parent company Honeywell, after the distribution of Cycle 1001 databases, which have an effective date of Jan. 14, Jeppesen informed Honeywell that the data file 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,” the urgent safety bulletin stated.
Databases that contain incorrect data — which must be corrected before use — are Cycle 1001 databases downloaded from Wingman Services before Jan. 12 and Cycle 1001 databases on programmed media and received before Jan. 12.
To fix this issue, a corrected database must be installed prior to the next flight, Honeywell officials said. For all units except the KLN 94, owners are directed to refer to the pilot’s guide for database update instructions. KLN 94 operators who downloaded the Cycle 1001 database before Jan. 16 should refer to Service Information Letter “Incorrect Dynamic Magnetic Variation Data on database cycle 1001.”
Honeywell officials add that if operators cannot determine whether their Cycle 1001 database falls within the categories listed above, or if there is any uncertainty about the correctness of the data, they should installed a corrected database.
