In reply to D.Lam's post.
The TQ registrations from TQN onwards were used for the Fokker F27 Quick Change 200 series (with some series vaiations within).
The TF rego was used for TFA thru TFM with TFA through to at least TFG being 100 series, TFH was a strange beast as the rego appearered on several aeroplanes, one of which was East West delivered I believe, and TFM was a pure Quick Change 200 series.
TFL and TFW (the latter sourced from All Nippon) were 200 series with no QC door, and TQS and TQT were QC's with the cargo door but no roller mats fitted. These generally were in BNE or DRW base and were seldom seen in Southern climes except when a C or D check was required. There were 150's and 600's in the mix somewhere but they were generally referred as 100 and 200 series.
TFB which was lost with all aboard off Mackay was actually the first delivered, continuing a poor record for "first of type" with TN, as TFA was delayed in delivery being retrofitted with wx radar.
Best all
