AN INSTRUCTOR PLT GAVE INSTRUCTION TO A STUDENT PLT IN A PA28 WITHOUT TOE BRAKES ON THE R SIDE. IN HINDSIGHT; THE INSTRUCTOR WONDERED IF HE ACTUALLY HAD FULLY FUNCTIONING DUAL CTLS IN THE ACFT.

Narrative

STUDENT PLT CAME IN SEEKING INSTRUCTION IN HIS OWN AIRPLANE. I HAD JUST STARTED THAT JOB AS CFI THE DAY BEFORE; IT WAS MY FIRST JOB OUT OF AN AERONAUTICAL UNIVERSITY. I HAD ZERO HRS OF INSTRUCTION GIVEN. WE WENT OUT AND GOT IN THE AIRPLANE TO LEAVE. IT WAS AN OLD CHEROKEE 140. IT HAD NO TOE BRAKES ON THE R SIDE OF THE COCKPIT. THE STUDENT; HOWEVER; HAD BEEN FLYING FOR MANY YRS AND HAD LOGGED OVER 200 HRS. I DECIDED; WITHOUT CONSIDERING FAR 91.109; THAT IT WOULD BE SAFE TO GO ON THE FLT. HE DID A NORMAL TKOF; SOME 4 FUNDAMENTALS; CONSTANT ALT TURNS; SLOW FLT; STALLS; AND WE THEN RETURNED TO SRB FOR A NORMAL LNDG. HE WAS A SAFE PLT. THIS WAS MY FIRST FLT ON WHICH I GAVE INSTRUCTION. WE WENT BACK INSIDE THE FBO AND I DEBRIEFED HIM AND SIGNED HIS LOGBOOK. HOWEVER; LOOKING BACK; I RECALL THAT I FORGOT TO NOTE THE EXPIRATION DATE OF MY CFI CERTIFICATE IN HIS LOGBOOK. AFTER HE LEFT; I STARTED TO WONDER ABOUT THE ABSENCE OF TOE BRAKES ON THE R SIDE. SO; I GOT OUT MY FAR AIM 95 AND STARTED SEARCHING. I REALIZE NOW THAT THIS SHOULD HAVE TAKEN PLACE BEFORE THE FLT. I FOUND FAR 91.109 AND BEGAN TO WONDER IF 'FULLY FUNCTIONING DUAL CTLS' INCLUDES TOE BRAKES. I STILL DO NOT KNOW. MAYBE THIS SHOULD BE ADDRESSED. I PLAN ON CALLING FSDO TO FIND OUT. I ASKED MY SUPVR AND HE DID NOT KNOW EITHER. FACTORS I BELIEVE CONTRIBUTED: LACK OF CFI EXPERIENCE; LACK OF SAFEGUARD POLICIES AT LCL FBO; EAGERNESS TO 'GET MY TICKET WET;' HAVING BEEN ON THE JOB ONLY 1 DAY; LACK OF SPECIFICITY IN 91.109; AND A STUDENT WHO WAS UNCONCERNED ABOUT FARS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR RAN INTO A FRIEND WHO IS EMPLOYED WITH THE FAA. HE PRESENTED HIS QUESTION AND WAS TOLD THAT IT WOULD DEPEND UPON A PERSON'S INTERP OF THE 'FULLY FUNCTIONING DUAL CTLS.' THE FRIEND OF THE PLT FELT THAT IF THE HAND BRAKE WAS WITHIN COMFORTABLE REACH; IT QUALIFIED AS A FULLY FUNCTIONING CTL.
