SR22 INSTRUCTOR AND STUDENT PLTS FAIL TO REMOVE TOW BAR PRIOR TO TAXI. PROP STRIKE RESULTS.

Narrative

PROP STRIKE OCCURRED DURING TAXI DUE TO TOW BAR NOT REMOVED FROM NOSE GEAR AFTER PULLING ACFT OUT OF ITS HANGAR. PF WAS LICENSED PVT PLT; UNDERGOING TRAINING TO COMPLETE FACTORY-APPROVED SYLLABUS TO TRANSITION TO THIS ACFT TYPE. PNF WAS FACTORY-TRAINED CFI. THE PF CONDUCTED THE PREFLT INSPECTION USING THE WRITTEN FACTORY-PROVIDED CHKLIST WHILE THE ACFT WAS STILL IN THE HANGAR. THIS PROC IS USED LOCALLY TO PREVENT BLOCKING THE HANGAR AISLE FOR LONG PERIODS OF TIME DURING PREFLT; FUELING AND LOADING. THE PNF CONDUCTED AN INDEPENDENT 'WALKAROUND' OF THE ACFT DURING AND AFTER THE PF'S PREFLT. THE ACFT WAS REPOSITIONED TO THE HANGAR AISLE JUST PRIOR TO BOARDING AND START. THE PF FAILED TO REMOVE THE TOW BAR AFTER THE REPOSITIONING: THE PNF (INSTRUCTOR) BOARDED THE ACFT WITHOUT MAKING A SECOND WALKAROUND AFTER THE REPOSITIONING. THE FACTORY CHKLIST PRESUMES THE ACFT WILL NOT BE REPOSITIONED AFTER THE PREFLT IS COMPLETE: THE 'TOW BAR...REMOVE AND STOW' ITEMS OCCURS ONLY IN THE PREFLT INSPECTION PROC. DURING THIS OP; THE PF CONDUCTED THE PREFLT WITH REF TO THE WRITTEN CHKLIST; BUT SKIPPED THE TOW BAR ITEM BECAUSE THE ACFT WOULD NEED TO BE REPOSITIONED FROM THE HANGAR TO THE HANGAR AISLE JUST PRIOR TO ENG START. THERE IS NO ITEM IN THE FACTORY CHKLIST TO CHK THE TOW BAR IN ANY PROC SUBSEQUENT TO THE PREFLT INSPECTION. COMPLACENCY: THE PNF (INSTRUCTOR) HAD OBSERVED THE PF CORRECTLY CONDUCT THE PREFLT AND REPOSITIONING OF THE ACFT MANY TIMES PRIOR TO THE INCIDENT DATE. THE PNF HAD SUCCESSFULLY MET THE TRAINING STANDARD IN THE EARLIER PORTIONS OF THE SYLLABUS (WHICH CONTAINED THE PREFLT; START AND TAXI PROCS). THE INSTRUCTOR INCORRECTLY FELL VICTIM TO THE 'COMPLACENCY TRAP' AND DID NOT CHK THE TOW BAR PARTLY BECAUSE HE DEEMED THAT TO BE WELL WITHIN THE PF'S EXPERTISE.
