A BE400A ON TOUCHDOWN DURING THE REVERSER DEPLOYMENT BOTH ENGS WENT INTO CUT-OFF MODE. RESTART OK.

Narrative

ON LNDG AT ZZZ ARPT; THE PF ATTEMPTED TO DEPLOY THE THRUST REVERSERS. THE REVERSERS DID NOT DEPLOY; INSTEAD THE THROTTLES WENT INTO CUT-OFF. THIS CAUSED THE ENGS TO FLAME OUT. WE PROCEEDED TO BRAKE; EXITED THE RWY AND HELD SHORT OF TXWY A AS ASSIGNED BY TWR. AFTER STOPPING WE RESTARTED THE L ENG AND TAXIED TO PARKING. WE ARE NOT SURE HOW THIS HAPPENED. OUR COMPANY IS LOOKING INTO THE THROTTLES TO SEE IF THERE IS A MECHANICAL PROB. AS A CREW; WE CTLED THE ACFT AFTER FLAMEOUT WITH NO PROBS AND CAUSED NO PROBS FOR OTHER ACFT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR WAS THE FO AND THE PNF AND STATED THE LNDG PROC WAS FOLLOWED PRECISELY. AT 50 FT THE THROTTLES WERE BROUGHT BACK TO IDLE AND ON TOUCHDOWN THE 'PIGGYBACK' REVERSER HANDLES WERE RAISED AND PULLED AFT FOR REVERSING BUT THE REVERSERS NEVER DEPLOYED. THE ENGS BOTH SHUT DOWN BUT WERE RESTARTED AND THE AIRPLANE WAS TAXIED TO THE HANGAR. MAINT FOUND NO PROB WITH THE THROTTLE INTERLOCK AND ON FLT TEST THE NEXT DAY THE THROTTLE SYS OPERATED NORMALLY. THE INTERLOCK SYS ON THIS AIRPLANE IS TOUCHY AND WILL NOT TAKE ROUGH HANDLING. THE RPTR DID NOT AND COULD NOT OBSERVE THE CAPT'S THROTTLE OP.
