Narrative:

Aircraft #1 went through runup at runup area, called clearance delivery and received a release. When told ready to go, pulled aircraft onto runway. Prior to sele cting CTAF, stopped aircraft to do a transponder/instrument/time check. In approximately time of 30- 45 seconds later, aircraft #2 descended onto runway passing overhead. The initial problem was aircraft #1 not selecting CTAF on, immediately prior to rolling out onto the active runway. The initial problem probably was caused by 2 factors: 1) pilot was introducing flying to a non flying passenger, and 2) he also is a relatively new instrument pilot. The corrective action was the lesson learned and he now is very aware of this departure procedure. For this pilot, this is the first such incident of any kind in over 35 yrs of flying which puts a real awareness in safety performance in his mind.

Title: PLT OF TURBO 210 TAXIES INTO POS AND HOLD ON ACTIVE RWY AT NON TWR ARPT. HE THEN ACTIVATES HIS RADIO TO CTAF FREQ AS A CITATION LANDS OVER THE TOP.

Narrative: ACFT #1 WENT THROUGH RUNUP AT RUNUP AREA, CALLED CLRNC DELIVERY AND RECEIVED A RELEASE. WHEN TOLD READY TO GO, PULLED ACFT ONTO RWY. PRIOR TO SELE CTING CTAF, STOPPED ACFT TO DO A XPONDER/INST/TIME CHK. IN APPROX TIME OF 30- 45 SECONDS LATER, ACFT #2 DSNDED ONTO RWY PASSING OVERHEAD. THE INITIAL PROB WAS ACFT #1 NOT SELECTING CTAF ON, IMMEDIATELY PRIOR TO ROLLING OUT ONTO THE ACTIVE RWY. THE INITIAL PROB PROBABLY WAS CAUSED BY 2 FACTORS: 1) PLT WAS INTRODUCING FLYING TO A NON FLYING PAX, AND 2) HE ALSO IS A RELATIVELY NEW INST PLT. THE CORRECTIVE ACTION WAS THE LESSON LEARNED AND HE NOW IS VERY AWARE OF THIS DEP PROC. FOR THIS PLT, THIS IS THE FIRST SUCH INCIDENT OF ANY KIND IN OVER 35 YRS OF FLYING WHICH PUTS A REAL AWARENESS IN SAFETY PERFORMANCE IN HIS MIND.
