P&WC Issues SB/CSPN for Fuel Cooled Oil Coolers



                            Pratt & Whitney Canada (P&WC) has issued Service Bulletin (SB) No. 7630 affecting all Citation V and Ultra equipped with JT15D-5A and JT15D-5D engines.
             A Commercial Support Program Notification (CSPN) No. 1006369R00 was also issued to offer assistance for operators to comply with the SB.
                     The bulletin was issued following discovery of an unapproved bonding seal material application on some fuel cooled oil coolers (FCOCs).
                 Operators are provided instructions to perform a one time inspection of the serial numbers found on the FCOCs for comparison to a list of suspect serials provided in Table 1 of the bulletin. The affected FCOCs are to be removed and replaced with another one not listed in Table 1.
The Category 3 bulletin should be completed within 200 hours or by the next minor inspection, whichever occurs first. Operators should also be aware that the program duration of the CSPN will terminate on November 30, 2013.
