Analysis
Twa flt 388 (DC-9, N924L) was in clouds climbing to 7000' when Baltimore (bwi) TRACON adzd that an acft (Piper PA-28R) was straight ahead at 3 mi dscndg fm 6700'. Flt 388 had passed 6000' & the capt requested a traffic avoidance vector. The TRACON ctlr instructed flt 388 to lvl at 6000' & turn left to 270 degs, but by that time, flt 388 was at 6400'. As flt 388 was turning left, it broke out of cloud tops & the aircrew saw the Piper PA-28 at their one o'clock position. The twa crew took evasive action. The twa capt said the Piper PA028 passed aprx 500' to 1000' laterally with no verticalseparation. The Piper pilot said he saw flt 388 as it came out of the cloud top in a left turn. He estimated that flt 388 passed with aprx 3/4 mi separation. The Piper was VFR & flt 388 was IFR & flying in the bwi arsa. The plts of both acft were in ctc with bwi TRACON, but they were on different radio freqs & were being handled by different ctlrs. Flt 388 was being handled by a trainee ctlr.
