October 31, 2019 – West Star is pleased to announce their first Aft Canted Bulkhead Modification for a Citation 680 at their East Alton (ALN) facility. This modification can be performed at any of the three, full-service West Star Aviation Textron Aviation Inc. Authorized Independent Service Facilities.

Textron Aviation’s Mandatory Service Bulletin (SB680-53-08R2) for the Aft Canted Bulkhead Modification is applicable to both Sovereign (680 S/N 1-349) and Sovereign Plus (680-S/N 500-531). For aircraft with 7000 or more
flight hours at the time of receipt, this service bulletin must be accomplished within 1800 flight hours or 24 months, whichever occurs first, from the date of receipt. Cost of the modification is covered under warranty for specific aircraft. Contact West Star for additional warranty information.

The SB680-53-08R2 is a mandatory modification that involves removal of the APU, associated heat shield and containment structures. The Aft Canted Bulkhead is modified by adding structural pieces to reinforce the bonded
assembly to prevent potential de-bonding of the vertical and horizontal stiffeners. This modification is being completed at West Star’s ALN facility along with the customer’s routine inspection event to minimize downtime.

“We are happy to be able to offer our customers a large array of services and upgrades to their aircraft when their routine inspections are due,” said Pat Welch, Program and Service Manager Piaggio/Cessna (ALN). “Our customers continually look to us to complete their maintenance in one convenient location within a reasonable timeframe, and this modification is another benefit we offer,” Welch continued.
