TAT Probe Icing??
TAT probe icing has caused problems for RR-powered 777s in the past - inability to achieve max rated thrust, thrust lever stagger, weird engine responses to thrust lever movement, etc. This problem was highlighted some time ago by a Boeing Bulletin, and later a procedure for TAT probe icing was incorporated in the QRH. The 'cure' was to put the engine EECs into ALTN mode, forcing them to use N1 as the thrust setting reference, rather than EPR.
Could this accident have been caused by a similar type of failure?
Anyone...???
