I was right seat PIC for the crash fire rescue equipment part 61 instructional flight, receiving flight instruction toward a CFI airplane rating from a left seat instructor pilot. During the preflight briefing, I briefed the instructor pilot on the procedure for 'maximum performance lndgs' as published in the approved pom for the M20K (copy enclosed). However, I neglected to mention during this briefing that, when performing a 'maximum performance landing' in a mooney out of the idle power/maximum descent angle confign that the instructor pilot is required to demonstrate during the flight, the throttle must be advanced off of idle at about 50 ft AGL to respool the turbocharger and to restore elevator effectiveness in the flare. Thus, during the actual approach to landing, I allowed myself to be distraction by the instructor pilot's expressions of dismay as I began the 50 ft ago 'throttle advance' which I failed to brief him about. Distraction, I failed to advance the throttle sufficiently and soon enough to enable a flare sufficient to avoid a nose-first impact and the resulting propeller strike. This incident could have been avoided at either of 2 levels. At the 'tactical' level, I should have initiated a missed approach at about 50 ft AGL (notwithstanding the fact that I was discouraged from performing missed approachs under the rules then in effect), as soon as it became apparent that the instructor pilot was distracting me. At the 'strategic' level, I recommend extension of the sterile cockpit rule to all operations below 300 ft AGL, even for instructional flts, when the PF is known to be proficient on takeoffs and lndgs in type.

Title: MOONEY M20K INSTRUCTOR PLT TRAINEE, WHILE DEMONSTRATING MAX PERFORMANCE LNDGS TO AN INSTRUCTOR PLT, LOST CTL DURING TOUCHDOWN CAUSING A PROP STRIKE.
Narrative: I WAS R SEAT PIC FOR THE CFR PART 61 INSTRUCTIONAL FLT, RECEIVING FLT INSTRUCTION TOWARD A CFI AIRPLANE RATING FROM A L SEAT INSTRUCTOR PLT. DURING THE PREFLT BRIEFING, I BRIEFED THE INSTRUCTOR PLT ON THE PROC FOR 'MAX PERFORMANCE LNDGS' AS PUBLISHED IN THE APPROVED POM FOR THE M20K (COPY ENCLOSED). HOWEVER, I NEGLECTED TO MENTION DURING THIS BRIEFING THAT, WHEN PERFORMING A 'MAX PERFORMANCE LNDG' IN A MOONEY OUT OF THE IDLE PWR/MAX DSCNT ANGLE CONFIGN THAT THE INSTRUCTOR PLT IS REQUIRED TO DEMONSTRATE DURING THE FLT, THE THROTTLE MUST BE ADVANCED OFF OF IDLE AT ABOUT 50 FT AGL TO RESPOOL THE TURBOCHARGER AND TO RESTORE ELEVATOR EFFECTIVENESS IN THE FLARE. THUS, DURING THE ACTUAL APCH TO LNDG, I ALLOWED MYSELF TO BE DISTR BY THE INSTRUCTOR PLT'S EXPRESSIONS OF DISMAY AS I BEGAN THE 50 FT AGO 'THROTTLE ADVANCE' WHICH I FAILED TO BRIEF HIM ABOUT. DISTR, I FAILED TO ADVANCE THE THROTTLE SUFFICIENTLY AND SOON ENOUGH TO ENABLE A FLARE SUFFICIENT TO AVOID A NOSE-FIRST IMPACT AND THE RESULTING PROP STRIKE. THIS INCIDENT COULD HAVE BEEN AVOIDED AT EITHER OF 2 LEVELS. AT THE 'TACTICAL' LEVEL, I SHOULD HAVE INITIATED A MISSED APCH AT ABOUT 50 FT AGL (NOTWITHSTANDING THE FACT THAT I WAS DISCOURAGED FROM PERFORMING MISSED APCHS UNDER THE RULES THEN IN EFFECT), AS SOON AS IT BECAME APPARENT THAT THE INSTRUCTOR PLT WAS DISTRACTING ME. AT THE 'STRATEGIC' LEVEL, I RECOMMEND EXTENSION OF THE STERILE COCKPIT RULE TO ALL OPS BELOW 300 FT AGL, EVEN FOR INSTRUCTIONAL FLTS, WHEN THE PF IS KNOWN TO BE PROFICIENT ON TKOFS AND LNDGS IN TYPE.
