Narrative

WENT TO TNP TO MEET INSTRUCTOR FOR BIENNIAL FLT REVIEW. INSTRUCTOR SUGGESTED WE PRACTICE ENG OUT PROCS AFTER LIFTOFF WITH ENG AT IDLE. DID A SATISFACTORY TKOF WITH REAR ENG AND INSTRUCTOR ASKED FOR ANOTHER WITH THE REAR ENG AT IDLE. LOST CTL OF AIRPLANE 200 YARDS OFF END OF RWY 26. FRONT ENG AND PROP BEYOND REPAIR. REAR PROP DAMAGE; WINGTIPS; GEAR DOORS AND VERT FIN EXTENSION DAMAGE. FLT ENDED INSIDE ARPT BOUNDARY WITH NO PROPERTY OR PHYSICAL DAMAGE. PLT SHOULD NOT ALLOW THE POS OF INSTRUCTOR TO INFLUENCE THEM TO TRY MANEUVERS NOT NECESSARY OR IMPRACTICAL. INSTRUCTOR SHOULD NOT ASK FOR GEAR UP AT SUCH LOW ALT. FAVORED ENG SHOULD BE ZERO THRUST; NOT IDLE. PLT SHOULD REFUSE TO DO ANYTHING WITH PLANE HE DOES NOT FEEL COMFORTABLE AND NOT BE INFLUENCED BY AN AUTH FIGURE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE ACFT OPERATED WAS A C337 AND THAT THE INSTRUCTOR NOT ONLY DIRECTED HIM TO DO A REAR ENG OUT PROC; BUT TO ALSO RAISE THE LNDG GEAR AT ONCE ADDING ADDITIONAL DRAG TOO EARLY IN THE ATTEMPTED CLBOUT. HE LEARNED IN A DISCUSSION WITH THE FAA FSDO MGR THAT THIS INCIDENT WOULD BE RECORDED ON HIS PLT RECORD FOR 2 YRS ONLY SINCE THE MAJOR BLAME WAS PLACED ON THE INSTRUCTOR WHOSE INSTRUCTOR CERTIFICATE WAS PROPOSED TO BE REVOKED. THE RPTR BELIEVES THAT ALL AIRMEN SHOULD BE CAUTIOUS IN ACCEPTING A BIENNIAL FLT REVIEW FROM ANY INSTRUCTOR UNTIL HIS QUALIFICATIONS CAN BE CHKED TO ASSURE THAT THE INSTRUCTOR IS APPROPRIATELY RATED AND HAS EXPERIENCE IN THE TYPE OF ACFT USED IN THE REVIEW.
