Pratt & Whitney Canada (P&WC) extended the Time Limited Dispatch (TLD) System Check inspection interval from 125 hours to 250 hours in Periodic Inspection Table 1. P&WC issued Temporary Revision No. 05-6 to Chapter 05-20-00 of the PW535B Engine Maintenance Manual affecting Citation Encore+ airplanes.
The engine manufacturer recommends the TLD system check be performed at a convenient time prior to accumulating 250 flight hours. An example given in the temporary revision is to complete the system check at 240 flight hours, to provide 10 hours of the TLD period remaining to rectify faults.
