Narrative:

PA24-200 cleared to descend from 9000 ft to 2000 ft by myr, sc, approach control at XA25 on may/xa/01, en route from cae to myr. At 40 DME (approximately) from cre VOR on radial from 270 degrees, X was crossing 8000 ft when approach said 'X, traffic alert! Traffic alert! 11 O'clock and approaching.' I was VMC and looking at all times. Scanning couldn't see the traffic for 5 or 7 seconds. Finally traffic appeared from blind spot of left engine, 500 ft ahead crossing north to south. X stopped descent and turning north (left), evasive maneuver, maintaining separation, told myr 'maintaining separation, already 500 ft above traffic.' this alert was given in uncongested airspace with only a few targets on the sector. X was in IFR flight plan cleared to descend from 9000 ft to 2000 ft. If pilots do not make evasive action, it would culminate in a collision mid air at 7500 ft. Other aircraft similar type had full view, approximately mid high side, r-hand windshield. Never took maneuver of evasion. IFR traffic on descent should not be given a 10-second notice to impact -- should be advised if in radar environment with at least a minimum of 5 mi. Possible cause: misattended radar control scope at myr approach control.

Original NASA ASRS Text

Title: PA24 AND ANOTHER SIMILAR ACFT HAD NMAC MYR CLASS E AIRSPACE.

Narrative: PA24-200 CLRED TO DSND FROM 9000 FT TO 2000 FT BY MYR, SC, APCH CTL AT XA25 ON MAY/XA/01, ENRTE FROM CAE TO MYR. AT 40 DME (APPROX) FROM CRE VOR ON RADIAL FROM 270 DEGS, X WAS XING 8000 FT WHEN APCH SAID 'X, TFC ALERT! TFC ALERT! 11 O'CLOCK AND APCHING.' I WAS VMC AND LOOKING AT ALL TIMES. SCANNING COULDN'T SEE THE TFC FOR 5 OR 7 SECONDS. FINALLY TFC APPEARED FROM BLIND SPOT OF L ENG, 500 FT AHEAD XING N TO S. X STOPPED DSCNT AND TURNING N (L), EVASIVE MANEUVER, MAINTAINING SEPARATION, TOLD MYR 'MAINTAINING SEPARATION, ALREADY 500 FT ABOVE TFC.' THIS ALERT WAS GIVEN IN UNCONGESTED AIRSPACE WITH ONLY A FEW TARGETS ON THE SECTOR. X WAS IN IFR FLT PLAN CLRED TO DSND FROM 9000 FT TO 2000 FT. IF PLTS DO NOT MAKE EVASIVE ACTION, IT WOULD CULMINATE IN A COLLISION MID AIR AT 7500 FT. OTHER ACFT SIMILAR TYPE HAD FULL VIEW, APPROX MID HIGH SIDE, R-HAND WINDSHIELD. NEVER TOOK MANEUVER OF EVASION. IFR TFC ON DSCNT SHOULD NOT BE GIVEN A 10-SECOND NOTICE TO IMPACT -- SHOULD BE ADVISED IF IN RADAR ENVIRONMENT WITH AT LEAST A MINIMUM OF 5 MI. POSSIBLE CAUSE: MISATTENDED RADAR CTL SCOPE AT MYR APCH CTL.
